CITY OF MILTON Coliform Monitoring Plan

System Information

Updated 7-8-2010

Sources: S01 – Well 3

S02 – Well 5

S03 – Well 7

S04 – Well 10

S06 – Well 12

S07 – Corridor Well #1

S08 – Corridor Well #2

Interties:

S05 - On Highway 99 with Lakehaven Utility District

S09 - At 10105 24th

Street East, Edgewood, with Mt. View-Edgewood Water Co.

Storage: 3 Steel Tanks

1. 1 Million Gallons

2. 350,000 Gallons

3. 2 Million Gallons

Treatment:

S01, S03, S04, and S06 are treated with gas chlorination for disinfection and are

treated with caustic soda (NaOH) for pH adjustment.

Corridor Wells 1 & 2 are treated with Hydrochloride for disinfection and aeration

for pH adjustment.

Pressure Zones:

The system is comprised of three different pressure zones. Wells 3, 5, 10, 12, and

Corridor Wells 1 & 2 are the primary source with Well 7 being the backup.

Wells 3, 10, 12, and Corridor Wells 1 & 2 are located in pressure Zone 1 and are

pumped into the distribution system and into the 350,000 gallon reservoir located

at 1700 block of 15th

Avenue. From the 15th

Avenue reservoir and Well 5, the

water is pumped into Zone 2 distribution system and to the 2 Million and 1

Million gallon reservoirs, where it is then pumped into Zone 3.

Population and Connections Served:

Population serviced is approximately 7868.

Connections: 2684

Routine Sampling Required by Regulation:

Nine samples per month

Triggered Source Monitoring

Rotation:

The water system has been divided into sections for sampling purpose. This

provides the operator the opportunity to maintain the proper representation that is

critical to the coliform monitoring plan. Samples drawn from each section every

month allows for that section to be tested quarterly. (refer to the map)

Triggered Source Monitoring:

Per the Groundwater Rule, if a total coliform-positive sample is detected, samples

will be taken prior to treatment from all sources that were operating when the

positive sample was taken. Source samples will be taken within 24 hours of

notification of a positive sample. Sample locations are at each well site as shown

on map.

Sampling Directions:

Once a sample location has been established, procedure for drawing a safe sample

is critical for the operator. If operator is unfamiliar with the procedure, the Water

Department asks them to refer to the reverse side of the sample form. Directions

for a sample draw are clear. The Water Department uses a disinfectant prior to

turning on any water at the site. This product is called Back-Down and is

available from Water Management Lab, Inc. free of charge. This ensures the site

to be free of any source that may give a false positive. The product comes in a

spray form and is easy to use. Simply fog the valve area completely and let it

soak for 15 minutes, keeping the sample site wet at all times. Flush the valve for

10 minutes. Then draw the sample, being careful to not contaminate the bottle

lid. Quickly replace cap after filling. Complete sample form (self-explanatory)

and wrap form around the bottle, securing with rubber band. The Water

Department has their bottles on a bi-monthly pick-up schedule with a courier

service from the Lab. The schedule is for pick-up every second and fourth

Tuesday of the month. Samples should be drawn first thing in the morning on the

day of pick-up and left for the courier in the lunch room refrigerator. In the event

of coliform positive result, the operator is required to retake the original sample

site as well as one upstream and one downstream with 24 hours notification from

the Lab. Addresses for these sites are on the address sheets. If the operator feels

these sites are not the best due to animal watering, vacant home or other reasons,

you may choose another site as long as it is within five meter connections from

the failed site. If the operator is in need of further assistance, refer to a copy of

the State Coliform Rules.

Records Keeping:

An effort to keep sample locations and actual draws current shall be maintained

on a regular basis. This will assist in maintaining proper sample rotation and

assist the operator in the event of a coliform positive result. In that instance, refer

to the map of sample sites for assistance. Copies of sample results will be kept

together for future reference. A copy of the State of Washington Coliform Rule

will be available for further reference.

IMPORTANT NOTICE ABOUT YOUR WATER SYSTEM Coliform Maximum Contaminant Level (MCL) Exceeded: Non-Acute MCL

The City of Milton water system, ID# 54950V in Pierce County routinely monitors for the presence of total coliform bacteria and in MONTH/YEAR this type of bacteria was detected. Although this incident was not an emergency, as our customer, you have a right to know what happened and what we did or are doing to correct the situation. Coliforms are bacteria which are naturally present in the environment and are used as indicators that other, potentially harmful, bacteria may be present. Coliforms were found in more samples than allowed and this was a warning of potential problems. The samples that showed the presence of coliform were further tested to see if other bacteria of greater concern, such as fecal coliform or E.coli were present. None of these bacteria were found. You do not need to boil your water. People with severely compromised immune systems, infants, and some elderly may be at an increased risk. These people should seek advice from their health care provider. What happened? What is the suspected or known source of contamination? At this time: � The problem is resolved. Additional samples collected were found to be free of coliform bacteria. � We anticipate resolving the problem by ____ / ____ / ____. � Other __________________________________________________. For more information, please contact (owner or operator) at ( ) ___-_____ or at

1000 Laurel Street Milton, WA. 98354

Please share this notice with all the other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments, nursing homes, schools, and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail. This notice is sent to you by ___________________________ Date Distributed ____ / ____ / ____.
