A.1.0 Non Technical Summary

Moylough Sewerage Scheme was completed in October 1986 with final commissioning in 1987. It

serves a peak population equivalent of 600. Following tertiary treatment through plastic media, the

final effluent discharges to a nearby stream in Moylough.

A.1.1 Existing Waste Water Treatment Works and Collection System

The plant comprises:-

• Raw Effluent screening and pumping

• Aeration/Activated Sludge treatment

• Clarification

• Sludge Return

• Final Effluent Flow monitoring and,

• Plastic Media Filtration.

The collection system consists of approx 1750 meters of sewer network. The network is all 225 mm

sewer except for 190 meters of 300mm and 430 meters of 375mm.

A.1.3 Nature and Quantity of Foreseeable Emissions from the Waste Water Treatment Plant

The existing Dry Weather Flow and Population Equivalent estimates for the Moylough catchment

are set out as follows:

o Existing Dry Weather Flow 0.00125 l/s or 107.93 m3/day

o Existing Population Equivalent 600 PE

A.1.4 Significant Effects of the Emissions on the Environment

Laboratory results show little or no significant deterioration in water quality between upstream and

downstream results. At the discharge point, the concentrations of BOD, COD, the nutrients and

ortho-phosphates are considerably up, however at the sampling point downstream have returned to

be directly comparative with upstream results.

A.1.5 Proposed technologies and other techniques for preventing or, where this is not

possible, reducing emissions from the wastewater works and

A.1.6 Further measures planned to monitor emissions into the environment and comply with

the basis principal of the basic obligations of the operator, i.e. that no significant pollution is

caused. (These two are addressed collectively below)

Sampling will continue in accordance with the sampling requirements of the Urban Waste Water

Treatment Regulations. Also, to be continued in place:-

o Monitoring of final effluent turbidity and phosphate is carried out, including data logging.

o Outputs from all monitors are connected to the PLC. Monitors are located upstream of

sample points.

o Influent sampling is provided downstream of the screens but upstream of grit removal.

o A final effluent sample point is provided down stream of all treatment processes. Also an

additional sampling point is provided prior to tertiary treatment.

A.1.7. Measures planned to monitor emissions into the environment

Currently Galway County Council carries out regular sampling of discharges from the agglomeration.

Galway County Council will continue with the system in place of sampling to comply with the Urban

Waste Water Treatment Regulations.

Galway County Council will put a system in place to provide for automatic flow monitoring and

sampling of influent, treated effluent and storm water discharges from the plant.

In order to calculate the potential additional waste water contributing to the Moylough WWTP, a list of planning applications that have been granted and those that have commenced since 2005 were obtained from the Planning Department within Galway County Council. No relevant applications were identified. Due to the lack of capacity at the Wastewater Treatment Plant in Moylough, development has been curtailed.

C. 1 Operational Information Requirements Moylough is currently served by a public Wastewater collection and treatment system, which provides primary, secondary and tertiary treatment for effluent from the village. It was constructed during 1986/1987. The treated effluent runs into a small stream which runs adjacent to the plant. This is located to the North-East of the village. Moylough Sewerage Scheme caters for a population equivalent of approx 600 persons. Sludge enters the sump pump chamber where there are 2 duty and 2 stand-by pumps in operation. Sewage is screened before entering the plant. From there it is pumped to the aeration tank. This tank is 7.5 meters square and approx 4.0 meters deep. The aeration tank is complete with macerator. Effluent then goes to the clarifier (diameter 11.3 meters) where sludge settles out. There is a sludge return facility and an overflow weir and scraper on the settlement tank also. Treated effluent passes through the filter media before passing through a perforated pipe to the discharge location. Tertiary treatment is in the form of plastic filter media. Effluent discharged in Moylough is partially through ground also through a perforated pipe to the discharge location. The sludge is dried out in the sludge drying bed before being taken off site for final disposal. C.1.1 Storm Water Overflows Storm water overflow is in the form of the overflow weir in the settlement tank which allows overflow in storm conditions. C.1.2 Pumping Stations There is no pumping station in the Moylough sewer network, only the pump sump at the inlet chamber. C.2 Outfall Design and Construction (Refer to Attachment B3 for Outfall Location Details) SW1 – Primary Discharge Point, Moylough WWTP The Primary Discharge Point is Referenced SW1 and is located at E: 163,031; N: 248,349. Treated effluent from the WWTP discharges via a 225mm outfall pipe to a Local Stream at a point adjacent to the treatment plant site. The outfall pipe discharges directly to the stream.

ANALYTICAL STANDARD OPERATING PROCEDURE SOP NO: ENV.001

PAGE: 1 of 8

PREPARED BY: Louise Brennan

DATE: 20/12/05

TITLE: Measurement of Biochemical Oxygen Demand

Version: 002

1 WARNING AND SAFETY PRECAUTIONS

Routine laboratory safety precautions shall be followed by analysts carrying out this test.

Special Hazards: Refer to material safety data sheets for details of hazards associated with chemicals used in this test.

2 INTRODUCTION The Biochemical Oxygen Demand (BOD) determination is an empirical test in which standardised laboratory procedures are used to determine the relative oxygen requirements of wastewaters, effluents and polluted waters. The test has its widest application in measuring waste loadings to treatment plants and in evaluating the BOD removal efficiency of such treatment systems. The test measures the oxygen utilised during a specified incubation period for the biochemical degradation of organic material (carbonaceous demand) and the oxygen used to oxidise inorganic material such as sulphides and ferrous iron. It may also measure the oxygen used to oxidised forms of nitrogen (nitrogenous demand) unless their oxidation is prevented by an inhibitor.

3 PRINCIPLE A 250 ml volume sample of water or wastewater or an appropriate dilution is incubated in an airtight bottle, at 20 + 1oC in the dark for 5 days. Sufficient micro-organisms and nutrients must be present in the sample to allow for the biodegradation of the organic matter present – hence for some samples dilution water will need to be seeded with micro-organisms. The dissolved oxygen (DO) in the sample is measured at the beginning and end of the test period. The reduction in DO during the incubation period yields a measure of the BOD.

4 SAMPLE HANDLING Samples shall be taken in accordance with SOP No ENV011. The samples shall be handled at the Laboratory in accordance with SOP No ENV011. BOD analysis must be commenced as soon as possible after sampling and every effort should be made to carry out analysis within 6 hr. in no case start analysis more that 24h after sampling. Samples should be stored at 4°C in the fridge (Equipment ID No. F 1) if kept overnight. Composite samples should be collected for a maximum of 24 hours. The same storage criteria as outlined above should be used for composite samples.

5 INTERFERENCES 5.1 Samples containing caustic alkalinity or acidity – samples with pH >8.5 or <6.0 should be

neutralised with a solution of sulphuric acid (H2SO4) or sodium hydroxide (NaOH) of such strength that the quantity of reagent does not dilute the sample more than 0.5%.

5.2 Samples saturated with DO – samples containing more than 9mg/l DO at 20 0C may be encountered in cold waters or in waters where photosynthesis occurs. To prevent loss of oxygen during incubation of such samples, reduce the dissolved oxygen (DO) to saturation at about 20 0C by aerating with clean filtered compressed air or by shaking the sample

5.3 Samples containing algae – algae present in samples may undergo respiration in the dark

during the test period. The respiration will consume dissolved oxygen and cause an apparent increase in the BOD. Samples containing visible amounts of algae shall not be analysed for BOD.

6 REAGENTS AND MATERIALS

6.1 BOD Nutrient Powder Pillows

6.2 Nutrient water: Place desired volume of deionised water in 10 L container and bring the temperature of the water to approximately 20 0C. Add 1 nutrient powder pillow (6.1) per 3 litres of water.

8.1.8 Meter should be calibrated before the analysis of samples and re-calibrated after a

maximum of 20 readings.

8.2 Monthly Calibration Check D.O. meter is oxygen and temperature calibrated as follows:

8.2.1 Prepare air saturated water by bubbling air into a beaker of stirred tap water. Allow 15 minutes for the water to come to saturation.

8.2.2 Calibrate the meter as described in section 9.1, place the electrodes in the water and measure the D.O. The reading should be 100 + 2 % saturation.

8.2.3 Remove the aerator and add a trace of cobalt chloride and an excess of sodium sulphide (approx. 1g Na2SO3 per litre) and stir slowly to bring the D.O. to zero

8.2.4 Place the electrode in the water and measure the D.O. The reading should be 0-2 %Sat.

8.2.5 Place some cold water in a beaker. Bring the temperature down below 15 0C. Stir gently and place the meter electrode and calibrated thermometer in the water. Wait for the readings to stabilise and note the temperature on the meter and thermometer. Increase the temperature of the water so that the temperature is between 15 and 30 0C. Record the temperature on the thermometer and meter. Readings should not differ by more than 0.5 0C in each case.

8.2.6 Record readings on a Monthly Calibration of Dissolved Oxygen Meters calibration sheet (Back of DO calibration book).

9 ANALYTICAL PROCEDURE

9.1 Sample Dilution

9.1.1 Because of the low solubility of oxygen in water (9.2 mg/l O2 at 20 0C) and because dissolved oxygen must be present throughout the test with a recommended 2 mg/l O2 remaining after 5 days, samples with a BOD greater than 7 mg/l O2 must be diluted with dilution water.

9.1.2 The dissolved oxygen concentration in a freshly prepared BOD bottle is approx. 9 mg/l O2 and the desired minimum consumption of oxygen during the test is 2 mg/l O2 and 1.0mg/L residual DO. Therefore a desired consumption of between 2 and 7 mg/l O2 is the optimum level of oxygen consumption to aim for in dilution.

9.1.3 When a Chemical Oxygen Demand value for an effluent or polluted water sample

is known then the BOD may be estimated at 0.6 times the COD and the appropriate dilution carried out.

9.1.4 Serial dilutions should be carried out on outflows of wastewater treatment plants, discharge licence outflows and samples of unknown concentrations.

9.1.5 A dilution scheme for BOD samples is shown in attached table. This is only used as a guideline. Other dilutions not stated in this table may be prepared. In addition dilutions can be prepared in a different manner e.g. 1:60 dilutions may be prepared by a 1:2 dilution of a previously prepared 1:30 dilution.

9.1.6 Dilutions are prepared in a clean 500ml graduated cylinder. The required volume of sample is added to the cylinder using the graduated cylinder or pipettes as appropriate. This is then diluted to the 500ml mark with the dilution water. The cylinder is then covered with parafilm and inverted 3 times to mix the dilution thoroughly.

9.2 Sample Analysis

9.2.1 Before testing, the temperature of the samples and dilution water are adjusted to about 200C by leaving at room temperature.

9.2.2 Check the pH result of the sample if previously analysed. Samples whose pH lies outside the 8.5 – 6.0 ranges should have their pH adjusted with acid or alkali solutions (6.12).

9.2.3 Fill a BOD bottle to overflowing with the diluted sample. Any entrapped air bubbles are removed by gently tapping the bottles with a spatula.

9.2.4 Calibrate the D.O. meter as described in section 9.1.

9.2.5 Place the D.O. meter probe into the sample bottle using a funnel and switch on the stirring paddle. Wash D.O. meter probe and funnel before and after each use.

9.2.6 Allow the DO reading to stabilise.

9.2.7 Record the DO as mg/l O2 (=DO0) to one decimal place

9.2.8 Remove the electrode and funnel from the bottle and stopper the bottle so as to exclude all air bubbles and place in the BOD incubator.

9.2.9 After 5 days measure and record the DO remaining in the bottle (=DO5).

9.2.10 Record all readings on a Biochemical Oxygen Demand Laboratory Sheet (Ref. LS001).

Both reagents should be previously dried in an oven at 103 – 1060C for 1 hour and stored in a dessicator. This standard has a BOD of approx. 198 mg/l O2 +/- 30mg/l O2. (Errors in QC results are normally in relation to the addition of the seed.) The Quality Control system requires that one QC standard is analysed with each batch of samples. In addition one blank dilution water sample shall be analysed with each batch of samples. A duplicate test sample must randomly be analysed each month. In the case of BOD test which takes 5 days to complete, it is not possible to repeat a batch of samples where the QC standard is outside the upper or lower action limits.

10.2 Nutrient water Blank - this is to check the quality of the unseeded dilution water and the cleanliness of the incubation bottles. Together with each batch of samples incubate a bottle of unseeded dilution water. Determine the initial and final DO. The DO uptake should not be more than 0.2mg/l.

11 EXPRESSION OF RESULTS

11.1 Undiluted Samples BOD = DO0 – DO5

Where DO0 = initial DO of the sample DO5 = final DO of the sample

11.2 Diluted Samples BOD = F ⎧ (DO0 – DO5) – F – 1 (B0 – B5)⎫

⎩ F ⎭ Where F = Dilution factor (e.g. for ¼, F = 4) DO0 = Initial DO of diluted sample DO5 = Final DO of diluted sample B0 = Initial DO of dilution water B5 = Final DO of dilution water

Where a dilution factor of greater than 10 (i.e. F >10) is used then the (F-1)/F factor is insignificant and may be ignored.

11.3 Results are expressed as mg/l O2.

11.5 Samples are reported to the nearest whole number.

11.5 When nitrification is not inhibited report the results as BOD5.

11.6 When nitrification is inhibited report the results as CBOD5 (i.e. carbonaceous BOD).

11.7 When analysing diluted or undiluted samples, DO5 values of < 2 mg/l O2 should not be

used and another dilution used instead. If an alternative, more suitable dilution has not been prepared then the result shall not be reported.

11.8 For diluted samples the following conditions also apply before a dilution factor may be applied: (a) The factor (DO0 – DO5) should be ≥ 2 mg/l O2 (b) The factor (DO0 – DO5) – F – 1 (B0 – B5) should be ≥ 1 mg/l O2 F If this is not the case then an alternative dilution should be used. If an alternative dilution has not been carried out then the result should not be reported.

12 MAINTENANCE PROCEDURES 12.1 Electrolyte solution in the StirrOx G oxygen sensor should be replaced as per the

instrument manufacturer’s handbook Refer to the instrument manufacturer’s handbook for further details of maintenance and trouble-shooting.

13 METHOD PERFORMANCE DATA 13.1 Method Detection Limit (MDL) / Lowest Reporting Value (LRV)

The MDL is 0.23 mg/l O2 and the LRV is 0.72 mg/l O2 (rounded up to 1 mg/l O2). These were determined by analysing 7 portions a of a river water sample (average BOD = 1.08 mg/l O2) and calculating the standard deviation (s). Method Detection Limit (MDL) = 3.14 x (s) Lowest Reporting Value (LRV) = 10 x (s) MDL and LRV data were recorded on a Method Detection Limit Data Sheet (Ref. LS00?).

13.2 Precision, Bias and Total Uncertainty Precision, Bias and Total Uncertainty were determined in accordance with Standard Methods for the Examination of Water and Wastewater. The QC standard data obtained on 11 separate days by different analysts was used. Precision, Bias and Total Uncertainty data was recorded on Method Performance Testing Data Sheet (Ref. LS00?).

TITLE: Measurement of Chemical Oxygen Demand

Version: 002


Routine laboratory safety precautions shall be followed by all analysts carrying out this test. Eye protection should be worn while carrying out this test. The safety shield should be used on the COD reactor while the reactor is in use.


2 INTRODUCTION The chemical oxygen demand (COD) is used as a measure of the oxygen equivalent of the organic matter content of a sample that is susceptible to oxidation by a strong chemical oxidant. For samples from a specific source, COD can be related empirically to BOD, organic carbon, organic matter.

3 PRINCIPLE The Chemical Oxygen Demand (COD) test measures the oxygen equivalent of the amount of organic matter oxidisable by potassium dichromate in a 50 % sulphuric acid solution. The sample is digested with the acid/dichromate solution in a closed glass digestion vial at 150 0C for 2 hours. After oxidation the amount of dichromate used up is measured colorimetrically using a uv/visible spectrophotometer.

4 INTERFERENCES Samples with high chloride concentrations cause precipitation in the acid/dichromate solution. The COD vials contain mercuric sulphate which will complex up to 2000 mg/l chloride. Seawaters samples requiring COD analysis should be diluted prior to analysis. Samples which form a precipitate should not be analysed.

5 REAGENTS AND MATERIALS 5.1 Deionised Water. Used in the preparation of all solutions. Refer to SOP No ENV.009

for the production and use of deionised water.

5.2 Commercially available screw cap vials containing sulphuric acid, potassium dichromate, silver sulphate and mercuric sulphate. This mixture is light sensitive and so the vials should be stored in the dark.

5.3 COD standard 100mg/l and COD standard 600mg/l both available from Reagacon. Potassium hydrogen phthalate. Obtained from two different suppliers. Used for calibration and QC purposes.

Absorbance standards are used in instrument performance verification on the HACH DR/2400 instrument. The set consists of three standards plus a blank. Each of the standards is certified to give a known absorbance value at a particular wavelength. The standards are used to verify that the instrument is performing in a consistent manner on a routine basis. The standards are measured at the following wavelengths: 420 and 520

Determining Photometric Accuracy: page 31 DR/2400 Spectrophotometer Instrument Manual.

Digest 2mls of each of the working calibration standards below and using the digested standards calibrate the instrument as outlined in the HACH Spectrophotometer Handbook.

The instrument is calibrated on a yearly basis and the calibration details are recorded on a HACH Spectrophotometer Calibration Sheet (Ref. CS002). A straight line calibration should be obtained with a minimum correlation coefficient of 0.999. The top standard absorbance should be within the allowed limits.

TITLE: Measurement of pH

Version: 002


Routine laboratory safety precautions shall be followed by all analysts carrying out this test.


2 INTRODUCTION pH is used to determine the acidic or basic character of waters. By definition it is the negative logarithm of the hydrogen ion concentration of a solution (i.e. pH = -log10 [H

+]). The pH scale ranges from 0 (very acidic) to 14 (very alkaline). The range of natural pH in freshwaters extends from around 4.5 for acid, peaty upland waters, to over 10 in waters where there is intense photosynthesis activity by algae. However, the most frequently encountered range is 6.5 - 9.0. In waters with low dissolved solids, which consequently have a low buffering capacity (i.e. low internal resistance to pH change); changes induced by external causes may be quite dramatic. Extremes of pH can affect the palatability of water and increase the corrosive effects on distribution systems. The effect on fish is also an important consideration and values that depart increasingly from the normal levels found, will have a more marked effect on fish leading ultimately to mortality. The range of pH suitable for fisheries is considered to be 6.0 to 9.0. Apart from the aspects just mentioned, pH values govern the behaviour of several other important parameters of water quality, for example ammonia toxicity, chlorine disinfection efficiency and metal solubility are all influenced by pH.

3 SCOPE AND FIELD OF APPLICATION This method refers to the determination of pH. The method applies to the following materials in accordance with the INAB P9 Classification System for Testing and Calibration: 766 WATERS Sub-class: .01 (for potable and domestic purposes), .02 (for irrigation and stock), .03 (for industrial and steam raising purposes), .04 (sewage), .05 (trade wastes), .06 (saline waters), .07 (bore waters) 781 CONSTITUENTS OF THE ENVIRONMENT Sub-class: .11 (waters other than saline), .12 (saline waters). The range of measurement is pH 2 – 12.

4 PRINCIPLE

This method describes the electrometric determination of pH using a pH meter. The basic principle of electrometric pH measurement is determination of the activity of the hydrogen ions by potentiometric measurement using a standard hydrogen electrode and a reference electrode. The electromotive force (emf) produced in the glass electrode system varies linearly with pH. Because single ion activities cannot be measured, pH is defined operationally on a potentiometric scale. The pH meter is calibrated potentiometrically using buffers which have assigned pH values.

5 INTERFERENCES 5.1 Oily or greasy samples may coat the glass electrode.

5.2 In dirty waters or solutions with suspensions, the diaphragm may become clogged.

Refer to manufacturer’s handbook for cleaning procedures.

5.3 Temperature will affect the pH and should always be noted when measuring pH.

6 REAGENTS AND MATERIALS 6.1 Reagent Grade Water. Refer to Appendix 5 of the Quality Manual for production

and use of reagent grade water.

6.2 pH buffer, pH = 2.00 + 0.02 @ 200C (used for calibration / linearity test).





6.7 pH buffer, pH = 6.87 + 0.02 @ 200C (used for quality control).

6.8 3-molar KCl solution (for combined electrode). Commercially available.

All buffer solutions used shall be certified as traceable to N.I.S.T. standards or equivalent. Buffer used for quality control purposes is obtained from a different supplier to that used for calibration purposes.

7.1 Conductivity/pH Meter - model WTW Inolab Level 3 with Sentix 81 pH combined electrode with integrated temperature sensor, and built in printer (Equipment ID No. E122). Reference temperature = 20 0C.

7.2 Magnetic Stirrer.

7.3 Beakers preferably polyethylene. 8 SAMPLE HANDLING

Samples shall be taken in accordance with SOP No ENV011. The samples shall be handled at the Laboratory in accordance with SOP No ENV011. Samples should be taken to room temperature before analysis. Determine pH within 35hours of the sample being taken


The instrument is programmed to be calibrated using the ‘Buffer Mrk1’ buffer set. The instrument may be calibrated using any two of the calibration buffers listed in section 6 above – the two used depending on the required range of measurement.

9.1 Daily / Before use calibration (pH range 4 to 7) This procedure is used to calibrate the instrument when analysing samples whose pH is between 4.0 and 9.0. For pH values outside this range refer to section 9.2 or 9.3. Buffers solution should be 20oC at time of calibration.

9.1.1 With the instrument in standby mode press the ‘online’ soft key followed by ‘OK’

9.1.2 Set the instrument to pH mode by pressing the ‘m’ soft key until pH is displayed on the screen. Note pH and conductivity may be simultaneously displayed on screen by pressing this soft key.

9.1.3 Press the ‘CAL’ soft key. ‘Cm1’ is displayed on the screen.

9.1.4 Remove the electrode from storage solution and rinse with DI water, blot dry with a soft tissue. Place the electrode into a beaker containing the first calibration buffer (i.e. 7.00) and while gently stirring with the magnetic stirrer press ‘RUN/ENTER’.

9.1.5 When ‘AR’ stops flashing ‘cm2’ is displayed. Remove the first buffer; rinse the electrode thoroughly with DI water and blot dry again. Immerse the electrode in the second calibration buffer (i.e. 4.00) and while gently stirring with the magnetic stirrer, press ‘RUN/ENTER’.

9.1.6 After measuring and reaching a stable value the slope is displayed. The

slope should be between -50 and -62. If not, refer to the Inolab Level 3 Handbook.

9.1.7 To terminate the calibration at this point press the ‘m’ soft key. The calibration details can be automatically printed out and the instrument returns to normal pH measuring mode.

9.1.8 Check the calibration by measuring pH buffer 6.87, record result in the pH calibration log book.

9.2 Daily / Before use calibration (pH <4.0) When analysing a sample whose pH is less than 4.00 the meter must be calibrated using pH buffers 2.00 and 6.00. To calibrate using these buffers repeat the above procedure 9.1.3 to 9.1.7, substituting pH buffer 2.00 and pH buffer 6.00 for buffers 7.00 and 4.00 respectively. QC check is pH buffer 4.00

9.3 Daily / Before use calibration (pH >9.0) When analysing a sample whose pH is greater than 9.00 the meter must be calibrated using pH buffers 9.00 and 12.00. To calibrate using these buffers repeat the above procedure 9.1.3 to 9.1.7, substituting pH buffer 9.00 and pH buffer 12.00 for buffers 7.00 and 4.00 respectively. QC check is pH 10.00

9.4 Linearity Test 9.4.1 Set the instrument to ‘mv’ by pressing the ‘>’ key (beside ‘Run/Enter’)

until mv is displayed on the screen.

9.4.2 Pour a portion of pH buffer 2.00 into a beaker, rinse the electrode with DI water and blot dry and place the electrode into the buffer while gently stirring.

9.4.3 When the reading stabilises print out the mv reading.

10 ANALYTICAL PROCEDURE 10.1 When the meter has been calibrated, it returns to the pH measurement mode

10.2 Rinse the electrode with DI water and blot dry with a soft tissue and then place

the electrode into a beaker containing the sample, gently stir, wait for the reading to stabilise and then record the result on pH, Conductivity & Salinity Laboratory Sheet (Ref. LS005).

10.3 Conductivity measurements may be made on the sample at the same time by removing the pH electrode, rinsing the conductivity probe with DI water and placing the probe into the beaker containing the sample. The conductivity result is displayed by pressing the ‘m’ soft key until a reading in μS/cm is displayed (or a combination of both pH and conductivity on the same screen). When a stable reading has been obtained, this may be recorded. (Refer to the Conductivity Method B.5).

10.4 Repeat step 10.2 for all subsequent samples / standards

10.5 Between single measurements the electrode must be rinsed with DI water prior to analysis

10.6 After use, replace electrode protective cap (ensure that it contains 3-molar KCl). 11 ANALYTICAL QUALITY CONTROL

11.1 Working QC Standard A pH buffer, pH = 6.87 + 0.02 @ 200C is used as a QC standard. The calibration slope which can be automatically printed out during calibration should be between -62 and -50. Otherwise check and if necessary replace the electrode. The Quality Control system requires that one QC standard is analysed with each batch of samples. In addition one duplicate test sample shall be randomly analysed each month.

12 EXPRESSION OF RESULTS 12.1 pH is expressed in pH units to 1 decimal place. Samples whose pH is less than 2.0

or greater than 12.0 are reported as <2.0 and >12.0 respectively.

TITLE: Total Suspended Solids dried at 103°C - 105°C

Version: 002




2 INTRODUCTION This method refers to the determination of suspended solids. They are determined gravimetrically and refer to the portion of solids that are retained on a filter of 2.0 µm (or smaller) nominal pore size under specified conditions.

3 SCOPE AND FIELD OF APPLICATION This method refers to the determination of Suspended Solids. The method applies to the following materials in accordance with the INAB P9 Classification System for Testing and Calibration: 766 WATERS Sub-class: .01 (for potable and domestic purposes), .02 (for irrigation and stock), .03 (for industrial and steam raising purposes), .04 (sewage), .05 (trade wastes), .06 (saline waters), .07 (bore waters) 781 CONSTITUENTS OF THE ENVIRONMENT Sub-class: .11 (waters other than saline), .12 (saline waters). The range of measurement is pH 2 – 12.

4 PRINCIPLE Suspended solids are determined gravimetrically. A well mixed sample is filtered through a weighted standard glass fibre filter the residue retained on the filter is dried to a constant weight at 103 - 106 0C. The increase in weight of the filter represents the total suspended solids. Refer to ‘Standard Methods for the Examination of water and wastewater’ 20th edition 1998.

5 INTERFERENCES 5.1 Non-homogenous samples should be homogenised as necessary. Large floating

particles or submerged agglomerates which remain non-homogenous after mixing should be excluded

5.2 Limit the amount of sample filtered to a volume that will not cause filter clogging.

5.3 Prolonged filtration times resulting from filter clogging may produce high results owing to increased colloidal materials captured on the clogged filter.

5.4 Samples with low pH may dissolve or form a hole in the glass fibre filter.

10 ANALYTICAL PROCEDURE 10.1 Filter Preperation

10.1.1 Place numbered filter papers into the oven to for at least 1 hour at 103 - 105 0C.

10.1.2 Cool to room temperature for at least 20 mins in a desiccator.

10.1.3 Store in the desiccator until needed and weigh on the analytical balance immediately before use.

10.2 Sample Analysis 10.2.1 Place the weighed filter paper wrinkled side up into the assembled Buchner

funnel and apply a vacuum.

10.2.2 Wet the filter with a small amount of reagent grade water to seat it.

10.2.3 Shake samples thoroughly before use. Homogenise non-homogenous samples as necessary according to SOP No 6. Using a graduated cylinder measure out a suitable volume of sample. The volume taken depends on origin of the sample (sample volumes normally range from 50 to 500mls – use a maximum of 1000mls for clean samples).

10.2.4 Filter the measured volume through the filter apparatus using suction.

10.2.5 Rinse the graduated cylinder three times with at least 10ml reagent grade water and transfer to the funnel. Rinse the inside walls of the funnel with reagent grade water and continue suction for about 3mins after filtration is complete.

11.2 Working QC Standard

Dissolve 0.100 + 0.001g of stock QC standard (11.1) in reagent grade water and dilute to 1 litre in a volumetric flask. Shake vigorously remove the suspension from the neck of the flask and measure out 250mls of the standard and filter as described in section 10. This suspension has a suspended solids content of 100 mg/l.

The Quality Control system requires that one QC standard is analysed with every batch of samples. Duplicates should be carried out monthly and should agree within 5% of there average weight

12 EXPRESSION OF RESULTS 12.1 Suspended Solids (mg/l) = (A - B) x 1000 x 1000 where:

Sample Volume (mls) A = Weight of filter + dried suspended solids (g) B = Weight of filter (g)

12.2 Results of analysis are expressed in mg/l and are reported to the nearest whole number

13 METHOD PERFORMANCE DATA 13.1 Method Detection Limit (MDL) / Lowest Reporting Value (LRV)

The MDL is 3 mg/l and the LRV is 8 mg/l . These were determined by analysing 7 portions a 10 mg/l standard and calculating the standard deviation (s). Method Detection Limit (MDL) = 3.14 x (s) Lowest Reporting Value (LRV) = 10 x (s) MDL and LRV data were recorded on a Method Detection Limit Data Sheet (Ref. LS00?).

13.2 Precision, Bias and Total Uncertainty Three separate standards covering the normal analytical range were analysed once on eleven separate days. Precision, Bias and Total Uncertainty data was recorded on a Method Performance Testing Data Sheet (Ref. LS00?).

TITLE: Measurement of Ammonia (High Range Salicylate Method) 0.4 to 50.0mg/l NH3-N

Version: 002




2 INTRODUCTION Ammonia is a product of the microbiological decay of animal and plant protein. It is also applied directly as fertilizers. The presence of ammonia nitrogen in surface water usually indicates domestic pollution. Ammonia in ground water is normal and is due to microbiological processes.

3 SCOPE AND FIELD OF APPLICATION Suitable for water waste water and seawater.

4 PRINCIPLE Ammonia compounds combine with chlorine to form monochloramine. Monochloramine reacts with salicylate to form 5-aminosalicylate. The 5-aminosalicate is oxidized in the presence of sodium nitroprusside catalyst to form a blue coulored compound. The blue is masked by the yellow colour from the excess reagent present to give a green coulored solution. Test results are measured at 655nm.

5 INTERFERENCES 5.1 Airborne cross contamination of the blank is possible in some laboratories and there

should be prepared before opening or handling any samples. If samples have alreadyopened prepare blank in another area of the laboratory.

5.2 Acid or basic samples should have there pH adjusted to pH7.

5.3 Further details may be obtained from Method 10031 of the HACH DR/2400 Manual

TITLE: Measurement of orthophosphate Using the PhosVer 3 (Ascorbic Acid )Method (0.02 to 2.50mg/l PO43)

Version: 002




2 INTRODUCTION Phosphorous occurs in natural water and in wastewater almost solely as phosphates. These are classified as orthophosphates, condensed phosphates and organically bound phosphates. Orthophosphate and condensed phosphates may enter the water body due to water treatment, larger quantise may arise due to the addition of detergents particularly from laundry. Orthophosphates are also applied to land as fertilizers and may enter the watercourse due to runoff. Organic phosphates are formed primarily by biological processes. Phosphorous is essential to the growth of organisms. Excessive quantities of phosphorous in a water body can cause eutrophocation.

3 SCOPE AND FIELD OF APPLICATION Suitable for water, waste water and seawater. USEPA Accepted for reporting for waster water analysis

4 PRINCIPLE The orthophosphate ion reacts with ammonium molybdate and antimony potassium tartrate under acidic conditions to form a complex. This complex is reduced with ascorbic acid to form a blue complex, which absorbs light at 880nm. The absorbance is proportional to the concentration of orthophosphate in the sample.

5 INTERFERENCES 5.1 Aresenate react with the molybdate reagent to produce a blue colour similar to

that formed with phosphate. Hydrogen sulphide will also cause interference. For other interferences refer to the HACH 2400 Procedures Manual, Method 8048.

TITLE: Collection and Handling of Samples Version: 002 1. WARNING AND SAFETY PRECAUTIONS Routine safety precautions shall be followed by the sampler when carrying out sampling. 2. INTRODUCTION This method refers to the collection and handling of samples for bacteriological and physio/chemical analysis and transport for analysis. 3. SCOPE AND FIELD OF APPLICATION This method is used for the collection of a water and waste water sample for bacteriological and physio/chemical analysis. It deals specifically with grab samples and composite samples.

3.1 Grab Samples: grab samples are single samples collected at a specific spot at a site at a specific time and are as such just a ‘snapshot’. When a source is known to be relatively constant in composition over an extended time or over substantial distances in all direction the sample may represent a longer time period and or a larger volume than the specific time and place at which it was collected. In such cases a source may be adequately represented by a single grab sample. Examples are protected groundwater supplies, water supplies receiving conventional treatment some well mixed surface waters but rarely, wastewater, rivers, large lakes, shorelines, estuaries and groundwater plumes. When a source is known to vary with time it may be necessary to sample at suitable intervals, seasonal variation may necessitate sampling over months. If the source composition varies in space samples may need to be collected from appropriate locations e.g. upstream and down stream. 3.2 Composite Samples: composite samples should provide a more representative sampling of heterogeneous matrices in which the concentration of the analytes of interest may vary over short periods of time and/or space. Composite samples can be obtained by combining portions of multiple grab samples or by using specially designed automatic sampling devices. The advantages of composite samples include reduced costs of analyzing a large number so samples, more representative samples of heterogeneous matrices and larger sample sizes when amounts of test samples are limited. The disadvantages include the loss of analyte relationships in individual samples, potential dilution of analytes below detection levels and increase and increase possibility of analyte interactions. If preservatives are to be used they must be added to the sample bottle initially so that all portions of the composite are preserved as soon as collected.

5. SAMPLE TAKING AND HANDLING 5.1 Chain of Custody One must be able to trace possession and handling of all samples from the time of collection through analysis and final disposition.

A Sample labels: the following information must be included on the label of all samples taken; sample type, date and time of collection, place of collection, name of person who carried out sampling and whether samples are preserved or not. Samples must be labelled on site.

B Sample seals: seal the sample with self adhesive paper seals, the seal should contain the following information sample number (if applicable), collector’s name, date and time of sampling. The seal should be attached in such a way that it is necessary to break it to open the sample container. This is only necessary for samples that are subcontracted.

C Field log sheet: the following should be included in the field log sheet: purpose of sampling; location of sampling point use GPS where possible; name and address of field contact; producer of material being samples and address if different from location; type of sample; method, date and time of preservation. If possible provide information on possible composition of suspect sampling. Record the number of samples taken; description of sampling point and sampling method; date and time of collection; collectors ID; sample distribution and how transported. References such as maps and photographs of the sampling site should be kept on file along with field observations and measurements (LS 033).

D Chain of custody record: a chain of custody record must accompany every sample that is subcontracted. It must include the following: sample number, signatures of collector, dated and time and address of collection, sample type, signature of persons involved in the chain of possession and inclusive dates and times of possession. This form can also include information on analysis requested. Upon receipt in the laboratory the details in the chain of custody record must correspond with the information on the bottle the condition of the sample on arrival should be noted by the receiving laboratory.

TITLE: Collection and Handling of Samples Version: 002 5.2 Sampling Methods Most samples are taken manually the sample apparatus (dipper bottle) must be rinsed thoroughly before taking the sample. The sample container type is very important due the fact that some sample analytes may dissolve into the walls of plastic containers, similarly, contaminants from plastic containers may leach into samples. Always consult with the subcontracting laboratory in relations to sampling requirements such as preservation and sampling containers and where possible use appropriate containers provided by the laboratory. Glass containers should be used for all organics analyses such as volatile organics, semi-volatile organics, pesticides, PCBs and oil and greases. Some analytes (e.g. bromine containing compounds and some pesticides, polynuclear aromatic compounds, etc.) are light sensitive and should be collected in amber coloured glass containers.

TITLE: Collection and Handling of Samples Version: 002 5.4 Sample Storage and Preservation Refer to table 1060:1 of Standard Methods for the Examination of Water and Wastewater 20th Edition for full details on sample preservation. Preservation does not stop but will help to retard chemical and biological changes that continue after a sample is collected. When testing for aluminium, cadmium, chromium, copper, iron, lead, manganese, silver and zinc samples should be acidified with nitric acid to bring the pH below 2.0 to minimize precipitation and adsorption on container walls. Temperature, pH and DO should all be tested on site as these parameters can change very quickly. Microbiological activity may affect the nitrate-nitrite-ammonia content, phenol or BOD concentration and therefore the shorter the time that elapses between collection of a sample and its analysis the better, such samples should be stored at <4oC to retard the growth of micro organisms. Zero head space is important in preservation of samples with volatile organic compounds and radon. If sample bottles contain preservatives before filling you must avoid overfilling and thus the loss of the preservative. 6. CALIBRATION STANDARDS Refer to SOP No ENV 003 for the pH meter, SOP No ENV 004 for the Conductivity meter and SOP No. ENV 012 for dissolved oxygen measurement. 7. ANALYTICAL PROCEDURE 7.1 pH Measurement

2 INTRODUCTION The Sigma 900Max portable sampler is designed to automatically collect and preserve samples from a liquid source. The sampler is suitable for collection of conventional and toxic pollutants and suspended solids. The sampler is designed for portable use and consists of three main sections- the top cover, the centre control section, and the bottle/base section. The three sections are held together by stainless steel latches which also serve as the connection point for the optional suspension harness. The sampler collects samples on either a timed cycle or in proportion to flow when used in conjunction with a flow meter. There are two flow-proportional modes: Constant Volume, Variable Time (CVVT) and Constant Time, Variable Volume (CTVV). Refer to Pages 7-9.

TITLE: Measurement of Ammonia (Low Range Salicylate Method) 0.02 to 2.5mg/l NH3-N

Version: 001




2 INTRODUCTION Ammonia is a product of the microbiological decay of animal and plant protein. It is also applied directly as fertilizers. The presence of ammonia nitrogen in surface water usually indicates domestic pollution. Ammonia in ground water is normal and is due to microbiological processes.

3 SCOPE AND FIELD OF APPLICATION Suitable for water waste water and seawater.

4 PRINCIPLE Ammonia compounds combine with chlorine to form monochloramine. Monochloramine reacts with salicylate to form 5-aminosalicylate. The 5-aminosalicate is oxidized in the presence of sodium nitroprusside catalyst to form a blue coulored compound. The blue is masked by the yellow colour from the excess reagent present to give a green coulored solution. Test results are measured at 655nm.

5 INTERFERENCES 5.1 Acid or basic samples should have there pH adjusted to pH7.

5.2 Further details may be obtained from Method 10031 of the HACH DR/2400

Manual

Regulation 16 (1) (l) of the Waste Water Discharge (Authorisation) Regulations 2007 states the following: “(l) Give details of compliance with relevant monitoring requirements and treatment standards contained in any applicable Council Directives or Regulations” The Urban Waste Water Treatment Regulations require the provision of appropriate treatment for all discharges to freshwaters. The Moylough WWTW does not discharge to a sensitive area as defined by the Urban Waste Water Regulations and the relevant required maximum final effluent standards are:

BOD 25mg/l COD 125mg/l SS 35mg/l

To date in 2009 three samples of the outflow from this plant were taken for analysis. The laboratory results showed that the limit values set in the regulations were not exceeded at all for BOD or COD and only once for SS parameters. In 2008 twelve samples were taken. The laboratory results showed that the limit values set in the regulations were exceeded 4 times for BOD, three times for COD and only five times for SS parameters.

F.1 Assessment of Impacts of Waste Water Discharges on Receiving Waters F.1.1 Give summary details and an assessment of the impacts of any existing or

proposed emissions on the environment, including environmental media oththan those into which the emissions are to be made.

The Moylough Wastewater Treatment Plant discharges to a local stream (known locally as Castlegar Stream) which in turn confluences further downstream with the Castlegar River (EPA River Code: 26C03). The local stream has not been allocated an EPA River Code and therefore is not monitored for water quality. The nearest water quality monitor is at Mountbellew Bridge (Station Number 0100) on the Castlegar River which shows a quality rating of 3 (Moderately Polluted) in 2002. The biological quality ratings (Q values) at the EPA monitoring location (Mountbellew Bridge) are shown in Table F.1.1 below: Sampling Stations Biological Quality Ratings (Q Values) No. Location 1979 1981 1983 1987 1992 1996 1999 2002 0100 Mountbellew Bridge

There is an EPA Hydrometric Station (Staff Gauge Only) (26105) downstream of the Waste Water Treatment Plant. Monitoring data of the effluent from the primary discharge point is included in Table D.1 and monitoring data from the monitoring points upstream and downstream of the primary discharge point is included in Table F.1. F.1.2 Table(s) F.1(i) (a) and (b) should be completed for the primary discharge

point

Tables F.1 (i) (a) and (b) are completed for the primary discharge point and are included at the rear of the attachment. F.1.3 Surface water monitoring locations upstream and downstream of the

discharge point shall be screened for those substances listed in Tables F.1(i) (a) and (b)

The surface water monitoring locations upstream and downstream of the discharge point have been screened for substances listed in Tables F.1 (i) (a) and (b) F.1.4 For discharges from secondary discharge points Tables F.1 (ii) (a) & (b)

should be completed. Furthermore, provide summary details and an assessment of the impacts of any existing or proposed emissions on the surface water or ground (aquifers, soils, sub-soils and rock environment), including any impact on environmental media other than those into which the emissions are to be made.

There are no secondary discharge points and therefore Tables F.1 (i) (a) and (b) are not applicable. There are no impacts on groundwater or other environmental media from secondary discharge points. The impact of the primary discharge point on the Castlegar Stream is evaluated in Section F.1.6

CURRENT WATER QUALITY STATUS AND TARGETS

Introduction

Under the Local Government (Water Pollution) Act, 1977 (Water Quality Standards for Phosphorus) Regulations, 1998, local authorities are responsible for maintaining and improving water quality to specific standards by 2007. The requirements of the regulations include the preparation of a baseline report and the preparation of an implementation report every two years. The baseline report described the existing river and lake water quality, proposed measures to improve and protect surface waters and set out a timeframe for implementation of the measures. This report, the fourth in a series of implementation reports, documents the current status of surface water quality, describes the implementation of the measures proposed in the baseline report and identifies problems, successes and future initiatives. Galway County Council and Galway City Council are implementing the requirements of the Phosphorus Regulations through an environmental management system approach. In line with this approach the measures identified in the baseline report have been fully reviewed and new measures and time frames have been adopted. The Phosphorus Regulations are similar in approach to the EU Water Framework Directive, 2000, which sets a target of good water status for all surface waters by 2015. Measures undertaken to comply with the Phosphorus Regulations will assist in meeting the requirements of the Water Framework Directive.

Current Water Quality

River Water Quality

The biological assessment of water quality, which gives a definitive description of pollution status, is carried out by the EPA on a 3-year cycle. The physico/chemical analysis of water quality takes place 4-12 times a year, giving an indication of water quality on the day of sampling only. The results in the baseline report were reported by sub-catchment and the same sub-catchments have been used for the purposes of the implementation reports. The seventeen sub-catchments are shown in Appendix 1, Map 1. Current river water quality is set out in Appendix 2, Table 1.1 and is summarised below:

Baseline Water Quality (1995 – 1997 or 1st available results) Number of Monitoring Stations 240 Number of Monitoring Stations with Satisfactory Water Quality 141 Number of Monitoring Stations with Unsatisfactory Water Quality 99 Current Biological Water Quality (based on most recent data) Number of Monitoring Stations 240 Number of Monitoring Stations with Satisfactory Water Quality 160 Number of Monitoring Stations with Unsatisfactory Water Quality 80 Current Level of Compliance with the Regulations Number of Stations in compliance with Regulation Requirements 164 Number of Stations not in compliance with Regulation Requirements 60 Number of Stations with Insufficient Data 16 The table above indicates that the biological water quality at 160 out of the 240 monitoring stations (66.7%) is of satisfactory quality. This represents an increase of 7.8% in the percentage of monitoring stations with satisfactory quality from the baseline (1995-1997). The analysis results indicate that 164 out of the 240 monitoring stations (68.3%) meet the biological or chemcial quality requirement and are thus compliant with the Regulations. The most recent EPA biological data indicates that one station is seriously polluted. The station in question, station 500 on the Owendaulleegh, was last sampled by the EPA in 2003 following the Derrybrien Landslide. Recent small stream assessment carried out upstream of this point by Galway County Council indicates that the biological status of the river has significantly improved. A further thirty-three monitoring stations are moderately polluted, as summarised below:

River Number of Stations Abbert 1 Ballinaboy 1 Ballyquirke 1 Bealanabrack 1 Carra Stream 1 Castlegar 1 Castlelodge 2 Clarinbridge 4 Coos 1 Dalgan 1 Eyrecourt 3 Grange 1 Kilcolgan 2 Kilcrow 3 Lisduff 2 Shiven 2 Sinking 2 Suck 2 Terryland 1 Toberdoney 1

A serious issue, indicated by the results, is the decline in the number of stations with pristine water quality (Q5) from 14 (baseline report) to 4. The decline in the number and percentage of river stations with pristine water quality is common across Ireland and has been highlighted in

the National Phosphorus Implementation Reports. A reversal of the trend is required as these sites are essential for the protection of pollution sensitive species and are necessary to function as reference sites for the purposes of the Water Framework Directive. The rivers with monitoring stations that have declined from pristine water quality are set out below:

River Number of Stations Owendalulleegh 1 Coos 1 Cammanagh 1 Dawros 1 Duniry 2 Failmore 1 Fooey 1 Owenglin 1 Tooreenacoona 1

Lake Water Quality

The baseline lakes and their status are set out in Appendix 2, Table 1.2. Based on sampling results collated by the EPA, the majority of the baseline lakes in County Galway have a satisfactory trophic rating, however, a number of the lakes have elevated phosphorus levels. The results indicate that Lough Corrib, the largest lake in the county, has improved from Mesotrophic to Oligotrophic, however, incidences such as localised algal blooms indicate that there are elevated nutrient levels at certain pressure points along the shoreline. Environmental pressures in the catchment are increasing and need to be addressed in order to protect the water quality of the lake. An aggressive alien plant species has recently been positively identified in Lough Corrib. Lagorosiphon major, a water weed, has become well established in the lake in recent years. It forms very dense infestations and poses serious problems for angling, boating, environmental and tourism interests. It also creates poorer living conditions for native plants, fish, birds and insects and can ultimately displace them from their natural habitats. A task force has been formed to determine and implement all options for the control and possible elimination of the weed. Several lakes that were not included in the baseline report are monitored 2-4 times per annum as part of the National Monitoring Programme for Lakes coordinated by the EPA. A list of these lakes and their status is set out in Appendix 2, Table 1.3.

IMPLEMENTATION OF MEASURES As part of the preparation of the baseline report measures were identified to improve and maintain water quality in accordance with the requirements of the Phosphorus Regulations. During the preparation of this report a review of the baseline measures was carried out and revised timescales and targets were determined. Table 2.1 in Appendix 2 summarises county-wide measures, describes actions taken in relation to these measures, sets out a timetable for completion and provides details on new measures proposed. Table 2.2 highlights the measures assigned for the maintenance or improvement of individual stretches of rivers. The table mainly focuses on unsatisfactory stretches as the majority of the measures relating to maintenance of satisfactory water quality are county-wide and are therefore detailed in Table 2.1. As all of the baseline lakes are considered to have a satisfactory trophic status the measures to maintain them in this condition are generally those which have already been outlined in Table 2.1. However Table 2.3 highlights the measures required for those lakes whose trophic status is threatened in all or a portion of that lake. In previous reports a table was included in the appendices detailing the measures to be taken on a sub-catchment basis. The majority of the measures detailed in this table related to the introduction of catchment management plans and to the upgrading or construction of new wastewater treatment plants. As the introduction of catchment management plans is adequately detailed in Table 2.1 and the sub-catchment table is not a requirement of the implementation report it has not been included in the current report. Table 2.4, which provides details on the proposed commencement dates for the upgrading and construction of new treatment plants, has been included in place of the sub-catchment table.

Water Protection Team

An important development within Galway County Council in relation to the implementation of measures is the establishment of a dedicated team within the Environment Section with responsibility for water protection. A Team Development Plan for 2006 has been prepared as part of the Galway County Councils Performance Management and Development System (PMDS). The development plan assigns targets and responsibility for measures relevant to the implementation of the Phosphorus Regulations. Regular team meetings are held to determine level of compliance with the plan. Five members of staff have been allocated to the water protection team.

PROGRESS TO DATE Although the water quality analysis results, as set out in Table 1.1 and 1.2, indicate that the water quality in Galway has improved in relation to the baseline quality, a significant amount of work is required to meet the targets of the Phosphorus Regulations by 2007.

Water Quality Management Planning

Water Quality Management Plans

The Western River Basin District project (WRBD) and Shannon River Basin District project (SRBD) were approved by the DoEHLG and the consultants commenced work in 2003 / 2004. The aim of the River Basin District Management projects is to establish an integrated monitoring and management system, develop a programme of management measures and produce a River Basin Management Plan. Characterisation Reports for the projects were completed in 2004 and a national monitoring programme was developed in 2006. The participation of Galway County Council and Galway City Council in the RBD projects should assist in meeting the standards of the Phosphorus Regulations.

Groundwater Protection Schemes

The Geological Survey of Ireland (GSI) is currently conducting surveys for the purposes of preparing a Groundwater Protection Response for County Galway. Galway County Council has commissioned the GSI to carry out this work in order to provide land surface zoning maps which outline vulnerable areas. This data will be used to assess the suitability of an area for certain activities from a planning and licensing perspective and will also enable the use of groundwater protection response sheets developed by the EPA and GSI.

Waste Management and Sludge Management

A draft Sludge Management Plan for Galway City and County was prepared in 2001 to identify current sources and to identify suitable outlets. The majority of the non-hazardous sludge in County Galway is generated through agricultural practices. The code of good practice developed to control the use of this material has recently been superseded by the EC (Good Agricultural Practice for Protection of Waters) Regulations, 2006. Galway County Council will be carrying out education and enforcement actions to ensure that the regulations are implemented. A review of the disposal of sludge from all local authority facilities is currently being carried out to ensure that disposal practices do not pose a risk of environmental pollution. A member of staff has been appointed to ensure that the sewage sludge register is maintained and that all information required is submitted. The development of a GIS system incorporating digitised spreadlands for IPPC facilties, local authority facilities and private contractors would be of significant benefit. In 2005, local authorities were invited by the EPA to express an interest in participating in Phase 1 of a Local Authority Prevention Demonstration Programme. A total of 14 applications were received representing 22 local authorities. The application submitted by Galway County Council and Galway City Council was one of three applications selected to become involved in the programme. Projects approved for Galway include waste prevention initiatives within the local authorities, the development of green communities and the employment of a green business officer to work with local commercial and industrial businesses.

Planning Control Measures

The Planning Section of Galway County Council deals with approximately 5500 applications per annum. An improved systematic referral system between the Planning and Environment Sections has been implemented, which ensures that all applications with a potential to cause environmental degradation are assessed by the Environment Section. The Environment Section recommends appropriate conditions to mitigate the environmental risk to waters, particularly in relation to the risk posed to groundwater from wastewater treatment plants. In addition staff members of the Environment Section frequently facilitate pre-planning meetings for the purpose of discussing wastewater treatment requirements for large developments. These activities have greatly improved the liaison between the Environment and Planning Sections on relevant issues. The Water Services Section deals with the drainage aspects of developments. To ensure that stormwater run-off does not impact on water quality the use of the Sustainable Drainage Systems (SuDS) is encouraged. Meetings have been held with the Environment, Planning and Water Services Sections to review relevant concerns such as the maintenance issues associated with the proliferation of large-scale private wastewater treatment systems. It is envisaged that this process will highlight water quality protection issues and will assist the Planning Section in the development of conditions governing the maintenance of large-scale private wastewater treatment systems. The Environment Section also works with the Forward Planning Section in relation to the County Development Plans, Strategic Environmental Assessments, Local Area Plans and Village Plans at both the pre-draft and draft stages of the process. Issues considered include the capacity and functionality of existing municipal treatment plants, the proliferation of existing private treatment plants and the protection required for vulnerable surface and ground waters.

Control of Point Discharges

Municipal Wastewater Discharges

Due to increased funding from the Department of Environment, Heritage and Local Government significant progress has been made in this area. The funding has enabled Galway County Council to bring forward the construction date on schemes originally falling outside the year 2007 and add new schemes to the list. The County has an extensive schedule of proposed capital works under the Assessment of Needs programme, which priorities proposed schemes in accordance with its regulatory responsibilities. The schedule of proposed capital works for the 2005-2007 period is expected to cost in the region of €152 million. In addition to the construction and upgrading of plants the capital works will involve the surveying and upgrading of foul sewer drainage systems. Municipal wastewater discharges are suspected to be responsible for unsatisfactory water quality at a number of baseline monitoring stations. The majority of the treatment plants that are suspected to be responsible for unsatisfactory water quality at baseline monitoring stations are currently being upgraded or are on the Water Services Investment Programme 2005 – 2007, as detailed in Appendix II, Table 2.4. However, it has been the experience of Galway County Council that delays in the construction of facilities is common. The requirement for phosphorus removal is assessed for new municipal wastewater treatment plants at the design stage. If delays are experienced in the upgrading of inadequate WWTPs it is highly unlikely that analysis results from downstream monitoring points will comply with the requirements of the Regulations. A sampling programme has been established and implemented in accordance with the requirements of the Urban Wastewater Treatment Regulations, 2001 and the recommendations

of the EPA. The programme will be fully compliant with the requirements of the legislation following the installation of flow proportional sampling equipment at three remaining facilities. It is expected that the installation of the samplers will be completed by the end of 2006. Samples are taken at the inflow and outflow points during each inspection and are also taken approximately 100m upstream and downstream of the plant during every second inspection. The Environment Section of Galway County Council is in the process of improving reporting procedures to ensure that all significant non-compliances are reported to the relevant Area Engineer. In addition the annual reporting procedure, on the level of compliance of each public WWTP with the requirements of the Urban Wastewater Treatment Regulations, 2001, will be formalised. The Water Services Section propose to improve operational management by developing and implementing Quality Management Systems for selected wastewater treatment plants.

Industrial & Commercial Discharges

Since the preparation of the previous implementation report a significant amount of work has been carried out in relation to the issuing and review of Section 4 and Section 16 licences. The limits set for nutrients have been reviewed and Ortho-Phosphorus has been included in the list of parameters, with the standard set at 1mg/l in general. As of July 2006 there are one hundred and sixty facilities with discharge licences in the functional area of Galway County Council and approximately two hundred and fifty facilities with discharge licences in the functional area of Galway City Council. Galway County Council carries out an inspection of each facility at a minimum of once per annum. The level of inspection is increased in the event of non-compliances with discharge licence requirements. Discharges are monitored for nutrients including Ammonia and Ortho-phosphate. One hundred and forty three routine inspections were carried out in 2005 and seventy eight routine inspections have been carried out to date in 2006. In the event of a breach of discharge licence conditions a warning letter is issued to the licence holder outlining the relevant non-compliances and requesting proposals for remediation. Thirty-six warning letters have been issued to date in 2006. Further non-compliances may lead to the issue of a Section 12 notice and the initiation of legal proceedings. Ongoing enforcement of the Water Pollution Acts and liaison with the Planning Section has resulted in a significant increase in the number of discharge licence applications submitted, with approximately 35 applications received annually. Applications come from a variety of sectors including housing developments, small industries and quarries. A significant amount of staff resources is required to process these applications. Individual discharge licences are reviewed on an ongoing basis. A list of discharge licences requiring review has been prepared and the licences will be reviewed on a prioritised basis in 2006 / 2007.

Single House Wastewater Treatment Systems

The baseline report identified that malfunctioning and inadequately maintained single house wastewater treatment systems can result in excess phosphorus loading to groundwater and surface water. As a result the surveying of domestic wastewater treatment systems in sensitive areas was adopted as a measure in the report. One domestic wastewater treatment systems were conducted upstream of bathing areas in 2004 and twenty one surveys were carried out in Clarinbridge in 2006.

The surveys were carried out in Clarinbridge due to the vulnerable nature of the oyster beds and the significant risk posed by wastewater treatment systems. It is proposed to carry out further septic tank surveys in the area in 2006. It is also proposed to identify other vulnerable areas, in conjunction with the Western RBD project, in which to undertake septic tank surveys. As part of the Clarinbridge survey a brochure, which provides guidance in relation to the maintenance of septic tank and wastewater treatment systems, was prepared and circulated. The brochure will be used as part of future surveys. A number of issues were identified in the course of the surveys. Firstly, it is very difficult to determine whether a wastewater treatment system or septic tank is functioning adequately unless there are indicators of significant problems. Secondly, it is difficult to prove that a system poses a significant risk of environmental pollution and therefore it is difficult to undertake enforcement actions. Under the County Development Plan 2003- 2009 all site assessments for an on-site wastewater treatment system must be carried out in accordance with the requirements of the EPA guidance documents on Treatment Systems for Single Houses and Treatment Systems for Small Communities, Business, Leisure Centres and Hotels. In addition all wastewater treatment systems must be NSAI accredited. Staff in the Environment, Planning and Housing Sections received training in relation to site assessment in accordance with the EPA guidance documents. Each RBD project is carrying out a detailed study on certain areas and the WRBD project is focusing on the issue of malfunctioning and inadequately maintained single house wastewater treatment systems. It is anticipated that the results of their research will assist in the determination of high risk areas and will assist in the development of suitable mechanisms for control of development in high risk areas.

Pollution Incidences / Complaints

A dedicated enforcement team was set up in 2004 to investigate and bring legal action against offenders where significant environmental pollution occurs and to ensure that complaints are dealt with in an adequate and timely manner. The team participates in the Enforcement Network operated by the Office of Environment Enforcement (EPA). Complaints received are recorded on a new database designed to enable flagging and tracking of complaints. Minor complaints are forwarded to the relevant community warden for an initial inspection to ensure early assessment of incidents/complaints. On receipt of a report / call from the community warden it is determined whether a technical inspection is required. Serious complaints are investigated by a technical member of staff as soon as possible and at a minimum within 24hrs of receipt of the complaint.

Control of Discharges from Agriculture and Forestry

Diffuse pollution from agriculture is considered to be one of the most significant sources of phosphorus loss to surface waters. In the long term it is anticipated that the reform of the Common Agricultural Policy (CAP), the introduction of regulations under the Nitrates Directive and schemes such as REPS will result in a reduction in the losses of phosphorus from agriculture. However a significant amount of work is required in relation to education and enforcement to ensure that the input from agriculture is decreased. In the baseline report five measures were identified to tackle both point source discharges and diffuse discharges from the agricultural sector. Due to the introduction of the EC (Good Agricultural Practice for Protection of Waters) Regulations, 2005, the introduction of agricultural bye-laws is not being considered at present. The remaining measures proposed for the agriculture

section include public education, farm surveys and the service of notices requesting nutrient management plans from large pig and poultry units.

Farm Surveys

Two hundred and seventy farm surveys were conducted in 2003, the majority of which were carried out in areas identified by the Lough Ree / Lough Derg project. A significant farm survey programme is proposed for 2006 / 2007. As current staff numbers will not enable the completion of farm surveys in all areas with unsatisfactory or declining water quality the programme will focus on both moderately polluted areas and areas where pristine sites have declined in quality. Surveys will focus on farm yards but other issues will be considered, where necessary, including nutrient management planning, generation of dangerous substances, landspreading practices and protection of buffer zones in vulnerable areas. An incremental approach will be used in relation to enforcement, commencing with a warning letter, followed by a formal notice and concluding with legal action where necessary. The “Farms Module” database developed by the LGCSB will be used for data entry if suitable. Recent research led by Teagasc under the EPA Environmental Research, Technological Development and Innovation (ERTDI) programme indicates certain areas of a catchment, usually less than ten percent, can contribute the majority of the phosphorus. It is hoped that further research in this area will enable the development of vulnerability maps and will thus enable Galway County Council to refine its farm survey programme.

Nutrient Management Planning

Galway County Council has recently developed a standardised form for inclusion with all planning applications for all farm developments. The form requires basic nutrient management information including details on the quantities of waste produced, storage capacity and nutrient levels of the soil. It is proposed to carry out inspections of all intensive pig and poultry units and mushroom facilities that are below the EPA IPPC licence thresholds to determine whether they pose a risk of water pollution. Nutrient management plans will be requested if considered necessary to protect water quality. If a full nutrient management plan is not required Galway County Council may request details of spreadlands under Section 23 of the Waste Management Acts, 1996 to 2003.

Forestry

A portion of the county-wide small streams survey was carried out by staff members of Galway County Council. It was noted during the survey that the water quality in several streams downstream of areas of forestry activity was unsatisfactory. In addition clear-felling is considered to be a likely cause of algal blooms in some upland rivers. At present proposals for aerial fertilisation submitted by Coillte are assessed by the Environment Section. In addition Galway County Council proposes to extend the existing referral system between the Planning and Environment Sections to include applications for forestry establishment and felling.

Monitoring Measures

At present monitoring for rivers is carried out on behalf of Galway County Council by the EPA and the SRBD laboratory in Roscommon. Monitoring of lakes is carried out by Galway County Council, EPA and SRBD. All river samples are analysed for molybdate-reactive phosphorus and all lake samples are monitored for both molybdate-reactive phosphorus and total phosphorus. In accordance with Section 22 of the Waste Management Acts, 1996 to 2003 Galway County Council and Galway City Council have prepared a list of closed landfill sites within the region for the purposes of identifying whether remedial measures are required. Twenty five closed landfill sites have been identified. At present the effluent from five of the closed landfills is being monitored. If sufficient resources are available it is proposed to include the landfills situated in vulnerable areas on the annual monitoring programme. As part of the preparation of the Water Framework Directive Monitoring Programme for Ireland the Western RBD and Shannon RBD forwarded detailed monitoring proposals to Galway County Council. Following review of the proposed monitoring points recommendations were made to alter the location of some of the proposed monitoring points and to include other points to ensure that all relevant point discharges will be monitored. The proposed monitoring points correspond with existing EPA monitoring locations. In addition a review of the monitoring required for the purposes of the phosphorus report was carried out. Galway County Council will endeavour to ensure that all baseline rivers and lakes are monitored at the required frequency in 2007 to ensure that the level of compliance with the phosphorus regulations can be demonstrated. A Small Stream Risk Score Methodology was developed by Dr. Aishling Walsh under the supervision of the EPA Regional Office in Castlebar Co. Mayo. The methodology was developed to enable the rapid assessment of the biological quality of first and second order streams. The Western RBD project co-ordinated a monitoring programme for the small streams in each of the sub-catchments in the region. Sampling was carried out by several organisations including local authorities, fishery boards and private consultants. The results enabled accurate classification of small streams that were originally classed as “probably at risk” or “probably not at risk”. It is envisaged that the results of the survey will be used to improve the targeting of measures by helping to identify sub-catchments that are causing the most severe water quality problems. It is also envisaged that staff, trained in the use of the methodology, will be able to use the system to identify the effects of discharges on small streams and to establish the baseline condition of rivers that are not sampled by the EPA. It should be noted that the surveys indicate that hydromorphological pressures such as drainage and siltation have a significant effect on water quality in localised areas. Samples obtained as part of the wastewater treatment plant and discharge licence monitoring programmes are analysed in the Galway County Council laboratory. A new quality system has been put in place, which is based on the European Standard ISO 17,025.

Special Catchment Studies

To date, due to staff constraints, it has not been possible to carry out significant investigations in areas where the analysis indicates unsatisfactory or declining water quality with an unidentified pollution source. In 2006 / 2007 it is proposed to carry out investigations to include farm surveys, septic tank surveys and river walks as relevant. As it will not be feasible to investigate all areas, the investigations will focus on areas where analysis indicates moderately polluted water quality or a decline from a pristine standard. These areas will be further prioritised based on the

uses of the water body, for example as a drinking water source or as a habitat for sensitive and endangered species.

Geographical Information Systems and other IT Infrastructure

Galway County Council stores all monitoring data obtained from analysis in the council laboratory and monitoring data obtained from the Shannon RBD laboratory in a LabInfo system. As the LabInfo system is stored on the network the data can be made available to all relevant personnel. At present the majority of data collected by the EPA is supplied in paper format or, if specifically requested, in excel format. It is envisaged that a data management system with a GIS component will be developed as part of the implementation process for the Water Framework Directive. Extensive use is made of the MapInfo GIS system during the planning process and in the investigation of pollution incidences. GPS co-ordinates have been obtained for the majority of discharge licence facilities, WWTPs and their associated monitoring points and river and lake monitoring points. The co-ordinates have been forwarded to the Western and Shannon RBD projects for inclusion in the GIS systems being developed. GPS units are used for recording all relevant locations including pollution incidents, small stream sampling locations and septic tank survey locations.

Consultative & Co-operative Measures

Co-operation and consultation with all stakeholders is essential to meeting the requirements of the phosphorus regulations and the Water Framework Directive. This is particularly important in relation to measures dealing with diffuse pollution sources such as agriculture and forestry. A central aim of the RBD projects set up to implement the Water Framework Directive is to enable co-operation between local authorities and all relevant stakeholders. As required by the Water Policy Regulations a River Basin District Advisory Council (RBDAC) has been established as a permanent forum for dialogue and interaction between interested parties and the relevant public authorities. In addition the public have opportunities to comment on draft proposals at various stages of project development. At present Galway County Council liaise with other public bodies including local authorities, fisheries boards, the Department of Agriculture and the National Parks and Wildlife Service on issues including pollution incidences, farm surveys and discharge licence applications as appropriate. Enhanced co-operation will be required for the purposes of investigation of areas where the source of pollution is unknown. In addition liaison will be required with the Department of Agriculture and Food, Teagasc and IFA for the purposes of farm surveys. The Galway County Heritage Plan 2004-2008 identified the prevention of the spread of the Zebra Mussel, an invasive exotic mussel, to the Western River Basin District as a priority action. As a result a regional group was established with representatives from local authorities, fisheries boards, National Parks and Wildlife Service, other interested public bodies and angling and boating organisations. An education officer has been employed and an education programme has been developed which includes the production of posters and brochures, the erection of signs at launching points, the development of a media campaign and the organisation of a conference. The extension of the education programme to address other invasive alien species is under consideration at present.

Public Education and Advisory Measures

Water quality issues are addressed as part of the existing environmental awareness programme. Articles in relation to septic tank maintenance, prevention of the spread of alien species, water conservation and protection have been included in the bi-annual newsletter circulated to all homes by the Environment Section. In addition, a water awareness programme has been developed and has been incorporated into the Green Schools programme. This has been implemented in approximately 80 of the 104 Green Schools in County Galway. Galway County Council staff also participate on an occasional basis in Teagasc seminars and REPS courses on water quality. A central requirement of the Water Framework Directive is to undertake a programme of public consultation and awareness. The public education campaign is likely to include education campaigns, the provision of technical advice and publicity campaigns.
