Update on Raw(untreated) Water Sample positive for e.coli bacteria:

Additional testing of the water supply revealed that the source of the E.coli bacteria to be one of the wells that supply the White Lodge Treatment Plant. That well remains off line and is undergoing inspection and will be tested before any further decisions can be made as to its return to use.

Officials at Massachusetts Department of Environmental Protection (DEP) agreed with this action plan and allowed the return to operation of the White Lodge Water Treatment , without using the offline well, and contingent upon additional testing.

The Water District was able to demonstrate to the satisfaction of the DEP that there is sufficient contact time between the disinfection at the Water Treatment Plant and the first water customer. Therefore, the return to use of the Water Treatment Plant was allowed.

There is no action that consumers need to take. There is no need to boil the water and the water is considered safe to drink.

Additional information will be made available on the dwwd.org website and our office which can be reached at781-329-7090.

Important Notice Regarding Your Drinking Water Posted July 13, 2017

PWS 3073000    Posted July 13, 2017

DRINKING WATER NOTICE

To all users of the Dedham-Westwood Water District

located in Dedham and Westwood, Massachusetts

This is an important notice – please have it translated for anyone who does not understand English.

We routinely monitor for the presence of drinking water contaminants to ensure the safety of the water supply.

On July 12, 2017, our water system learned that a raw (untreated) water sample collected on July 11, 2017 at the White Lodge Water Treatment Plant tested positive for E.coli, which is a fecal indicator. Fecal indicators are used to detect ground water sources that may be susceptible to fecal contamination which may contain harmful viruses or bacteria. Raw water samples from all five of the wells treated at the Plant tested clean, but a sample collected of combined raw water tested positive. The White Lodge Water Treatment Plant was turned off once we learned of the sample result, and is presently turned off.

The water delivered to your taps through the distribution system is disinfected with chlorine to kill viruses and bacteria, including E.coli. It is important to note that the treated water from the Plant and treated samples collected in the distribution system did NOT detect any fecal contaminants.

Even though none of the chlorinated samples tested positive, our chlorine disinfection system at the White Lodge Water Treatment Plant has not been certified by the MassDEP as 4-log compliant for 99.99% virus inactivation.  In accordance with the federal Ground Water Rule (GWR) requirements, we are notifying you of the situation and conducting additional sampling to evaluate the extent of potential fecal contamination and will take further actions as necessary.

WHAT SHOULD YOU DO? WHAT DOES THIS MEAN?

This is not an emergency, you do not need to boil your water or take other corrective actions at this time.

The USEPA requires us to provide you with this notice and the following information on fecal indicators, even though the well with the fecal indicator is no longer in use: “Fecal indicators are microbes whose presence indicates that the water may be contaminated with human or animal wastes. Microbes in these wastes can cause diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for infants, young children, some of the elderly, and people with severely compromised immune systems.” These symptoms can also be caused by issues unrelated to drinking water. If you experience any of these symptoms and they persist, or, if you have specific health concerns, you may want to discuss such concerns with your doctor. General guidelines on ways to lessen the risk of infection by microbes are available from the EPA Safe Drinking Water Hotline at 1-800-426-4791 or online at http://water.epa.gov/drink/contaminants/basicinformation/pathogens.cfm.

Please share this information 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.

WHAT IS BEING DONE?

We continue to maintain chlorine levels throughout our system and monitor for the presence of fecal contaminants in the sources and distribution system to ensure the safety of the water supply. Our system is undergoing repeat testing and evaluation to determine if the current level of treatment is adequate or if additional corrective actions are necessary to reduce the risk of potential fecal contamination in our drinking water supply.

We are in contact with MassDEP during this process who will evaluate the effectiveness of the steps taken and determine if any further action is required. If necessary, you will be notified again if you need to take any corrective actions. This notice does not affect persons using private drinking water wells.
