Mr. Steve MooreSan Francisco BayRegional Water Quality Control Board1515 Clay Street, Suite 1400Oakland, CA 94612

Dear Mr. Moore:

Subject: Public Solicitation of Water Quality Information

In response to the State Water Resources Control Board's (SWRCB) March 14, 2001 requestfor water quality information, the Alameda County Water District (ACWD) is submitting thefollowing information:

1. Results of Weekly Watershed Monitoring. Key points within the watershed aremonitored by ACWD on a weekly basis for the following: flow, pH, total dissolved solids,conductivity, hardness, nitrate as N, temperature, turbidity, and chlorides This weeklydata is being provided electronically in a Microsoft Excel spreadsheet. One Excel fileexists for each year from 1997 to 2001. Within each Excel file there are severalworksheets. Each worksheet represents a particular sampling location.

2. Site Codes and Approximate Coordinates. The watershed monitoring samplinglocations names are abbreviated with site codes. The site code file provides a list ofthese abbreviations along with the approximate geographical coordinates for eachsampling location. This information is being provided electronically in an Excel file titled"Site Codes."

3. Procedures and Location Maps for Weekly Watershed Monitoring. Key pointwatershed monitoring procedures and locations are also provided electronically in aMicrosoft Word document titled "Alameda Creek Watershed Monitoring Key PointProcedures & Maps."

4. Diazinon Results and Additional Sampling at the ACWQMS. We understand thatAlameda Creek, Arroyo de la Laguna, Arroyo Del Valle, and Arroyo Hondo have beenlisted as impaired water bodies in the Clean Water Act Section 303(d) due to thepresence of diazinon. Periodically, surface water samples are collected at the ACWDAlameda Creek Water Quality Monitoring Station (ACWQMS) for analysis of diazinonand other water quality parameters. This data has been provided electronically in anExcel file titled "Diazinon & ACWQMS analyses."

As requested, we are also submitting two hard copies of the information described above.Along with the hard copies, you should find a map showing the relative locations of the keypoint sampling locations within the Alameda Creek watershed. We hope this map will be usefulto you; unfortunately, it is not available in an electronic format.

If you have any questions or need any additional information, please feel free to contact me at(510) 659-1970, extension 511, or Marian J. Gonzalez at (510) 659-1970, extension 546 or [email protected].

ALAMEDA COUNTY WA TER DISTRICTAlameda Creek Watershed Key Point Monitoring Procedures & Locations

General Instructions

The following instructions are intended to help orient personnel with watershed monitoringtechniques and the watershed field observations scheduled to be done one day each week.

At each key point location. look carefully at the water and surrounding land for strange thingslike oily. foamy. milky, or colored water, dumped containers of hazardous materials. and othersuspicious activities. Take a photo to document anything strange and record the observationson the field sheet. In the case of inclement weather or impassable roads. do a visual checkfrom a distance and skip the field measurements.

After visually inspecting the area, measure the water's chloride concentration, conductivity.nitrate concentration, pH, turbidity. and temperature. Always record the water quality readingson the field sheet. If any of the field water quality data seem abnormal, obtain a sample forlaboratory analysis. Also obtain a sample if any visual abnormalities are present.

A. Bring the following items on the weekly watershed monitoring run:-chloride meter kit (calibrated) -keys (ACWD #206. #208. Yale,-conductivity meter kit (calibrated) Vallecitos and SFWD dimpled key)-nitrate test strips -screwdriver-nitrate colorimeter kit (to be used the first -pliers

sampling day of every month and when- -permanent felt tip penever nitrate test strips read >10mg/L) -camera and film

-pH meter (calibrated) -cooler with ice for samples-turbidimeter-thermometer If outside lab analysis is requested:-one 1-liter sampling bottles - sixteen 500mL sample bottles-three 500mL sampling bottles - labels-deionized water and spray bottle - Chain of Custody Forms-field binder with data sheets (See Section D)

B. Before leaving headquarters:

1. Call the WTP2 Water Treatment Plant operator (ext. 612). Ask the followingquestions and record the answers:

Revised 9/99

What PT (Peralta-Tyson) wells are operating?What Mowry wells are operating?

2,4.5, for example.3.6.8. for example

Pg 1

When making field obseNations at the PT and Mowry Wellfields, take fieldmeasurements at a well that is running and is the highest priority on the following list.

Highest Priority-->---->---->---->---->--Lowest Priority

PT Wellfield 1 4 2 3 5 6 7 8

Mowry Wellfield 1 7 9 3 2 8 6

2. Call the following locations for USGS gage heights.a.) USGS @ Niles (ACWQMS)b.) Arroyo de la Laguna near Pleasanton (ADLL_NP)c.) Arroyo Valle at Pleasanton (ADV_AADLL)

(510) 797-7493(510) 862-2912(510) 426-5349

-Record gage height on field data sheet.-Use corresponding rating table in field binder to obtain flow and record onfield data sheet.

3. Perform calibration check on Turbidimeter & record in calibration labnotebook.

C. If the field measurements are outside of these normal ranges, obtain a sample, placein the cooler and return to headquarters for laboratory analysis.

IConstituent I Lower Limit I Higher LimitI

Chloride None 250 mg/L

Conductivity None 1500 uS

pH 6.5 10

Nitrate None 10 mg/L*

Temperature 5°C (40°F) 25°C (7rF)

*If nitrate screen test strip reading is greater or equal to 10 mg/L, obtain anotherreading using nitrate colorimeter and record on data sheet.

D. If outside laboratory analysis is requested, the following steps must be taken:

1. Obtain at least two Chain of Custody forms from the cabinets in the watercontroller's workstation and place them in the field binder. When filling these formsout follow the example in the field binder.

Revised 9/99 Pg 2

2. Obtain the sixteen pre-printed sample identification labels from the bulletin boardacross from the Water Quality Supervisor's office in the ACWD laboratory.

3. Before leaving the ACWD laboratory, verify that the identification labels arewith the correct information. Place labels in the front pocket of the field binder.

4. Obtain sixteen clean and empty 500mL plastic sampling bottles.

5. In the field, obtain a 500mL sample from each of the key point locations that hasflow and perform the following immediate steps:

a.) affix the appropriate identification label to each bottle. Make surethe label corresponds with the correct sampling point code on the fieldsheet. (write the Well # on the respective Well sample identificationlabels)b.) verify or correct the sample date on the labelc.) write the sampling time and note the field conditions on the labeld.) place the sample bottle in the ice chest.

6. Complete the Chain of Custody form (see examples).*Make sure to only include the site where samples where obtained (Le. ifthere was no flow don't put that site on the form). There should be the samenumber of samples and lines entered on this form.*Verify what analyses are requested (Le. TDS, chloride, nitrate). This mayvary from week to week.

7. Return all water sample bottles, unused sample identification labels, together withthe completed Chain of Custody form to the ACWD laboratory

8. Relinquish custody of the water samples to the ACWD laboratory by getting alaboratory person to sign the "Received by:" section of the Chain of Custody form.DO NOT leave the water samples in the laboratory without properly relinquishingcustody.

9. Place a copy of the Chain of Custody form in the field binder with the completedfield sheet.
