Total Trihalomethanes (TTHM) Early Notification Mailing
Total Trihalomethanes (TTHM) Update as of 08/29/2011
Milford Water Department in an effort to help reduce TTHM levels throughout the system is working with its engineers to install an Activated Carbon layer in one of our slow sand filters here at the Dilla Street Treatment Plant which will help reduce the amount of organics in the water which in turn will help lower the TTHM levels in the system. To date our engineers have collected all of the data needed to create an installation plan and design and will be presenting to the MassDEP this week, the Draft Plans are now available for view. There are still a few logistical issues that need to be worked on before the installation can begin and as always we must get approval from the DEP. The Company has set a realistic timeframe for the installation to be completed and functioning to be near the end of October and expect to see lowered THM levels during the 4th quarter. We will continue to update the website as things progress.
MWC took another round of TTHM on August 25th and are now available for view. The results again remain high and we are continuing to conduct spot flushing and monitoring the chlorine levels in the system. We had originally planned to conduct another sample round during the week of the 15th but elected to do some Total Organic Carbon (TOC) instead to see if these levels had dropped with the addition of our Clarks Island Wellfield being blended with the surface waters of Echo Lake. These levels changed very little from our previous TOC monitoring prior to its addition, the Company had expected to see some change in the levels these results are now available for view as well. MWC will be conducting its regular quarterly sample round of TTHM and Haa5 prior to September 30th. As always Milford Water Department is committed to providing to our customers the highest quality of drinking water available and we continue to strive to improve our system and our customer service.

Update as of 08/12/2011
Milford Water Department in an effort to help reduce TTHM levels throughout the system is working with its engineers to install an Activated Carbon layer in one of our slow sand filters here at the Dilla Street Treatment Plant which will help reduce the amount of organics in the water which in turn will help lower the TTHM levels in the system. This was done in Winthrop Maine with good success where they were experiencing the same type of issues with TTHM in their system. Within the next two weeks we should have all of the details needed and be able to provide an expected completion date once we have this we will update this site.
MWC took another round of TTHM on August 4th and are now available for view. The results remain high at this time and we are continuing to conduct spot flushing and monitoring the chlorine levels in the system. We will conduct another round of TTHM during the week of August 15th.

To all customers of the Milford Water Department (MWC) located in Milford, Massachusetts
Total Trihalomethanes (TTHMs) are Above Drinking Water Standards
This notice is to advise our customers that our water system is in noncompliance with the drinking water standards for Total Trihalomethanes (TTHMs). Similar notices were issued to you in January and April of this year for this ongoing violation. Although this is not an emergency, as our customers, you have a right to know what happened, what you should do, and what we are doing to correct this situation.
We are required to monitor the drinking water for TTHMs levels on a quarterly basis (once every three months). The results of last quarter’s sampling were received on July 7, 2011 and show that our system exceeds the standard or maximum contaminant level (MCL) for TTHMs. The standard for TTHMs is 80 parts per billion (ppb) and is determined on a quarterly basis by averaging all samples collected by our system for the last 12 months. The average level of TTHMs between July 2010 and June 2011 was 82 ppb.
What does this mean?
This is not an immediate risk. If it had been, you would have been notified right away. There is nothing you need to do. You do not need to boil your water, use an alternative (e.g., bottled) water supply or take other corrective actions. However, pregnant women, infants, and women of childbearing age may be at increased risk and should seek advice from their health care providers if they have any concerns. Some people who drink water containing (TTHMs) trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys, or central nervous system, and may have an increased risk of getting cancer.
What happened? What is being done?
TTHMs are a byproduct of chlorine disinfection which forms when chlorine combines with natural organic matter commonly found in surface water supplies. TTHMs levels can vary depending on a number of factors including the amount of chlorine used, amount of organic plant material in water sources, temperature, and seasons. The MWC is working to reduce the TTHM levels while also maintaining appropriate levels of disinfectant in the water necessary to avoid bacterial issues. MWC is working with MassDEP on evaluating immediate short-term operations changes and long-term upgrades to the treatment plant and system with the intention of correcting this issue.
MWC has done some research and has found that some activated carbon type filters can help remove or lower chlorine and TTHM levels. For more information on filters please refer to US EPA Filter Facts at http://water.epa.gov/aboutow/ogwdw/upload/2005_11_17_faq_fs_healthseries_filtration.pdf.
A question and answer document on health effects, precautions, and water treatment options for TTHMs has been provided by MassDEP and is available on the MWC website. You can also contact the US EPA Safe Drinking Water Hot Line at #1-800-426-4791.

Total Trihalomethanes (TTHM) Testing Results
The first quarter 2011 results have come down significantly as compared to the fourth quarter 2010 results for the THM and HAA testing. The data has been sent to MassDEP and is currently under review.
