The Town of Westminster Has Achieved Tier 2 Compliance for Total Trihalomethanes

The Town of Westminster Water Department is pleased to announce that we have achieved compliance and are no longer in violation of a Tier 2 Massachusetts Drinking Water Regulation. Together, our team of water professionals executed a plan to reduce the locational running annual average (LRAA) for total trihalomethanes (TTHM) in the public drinking water supply, including flushing the water distribution system, and continually sampling and monitoring the levels of TTHM in the water to ensure our actions were having an impact and to protect public health and safety.

TTHMs are a group of disinfection byproducts that form when chlorine compounds, which are used to disinfect water, react with other naturally occurring chemicals in the water. They are colorless and will evaporate out into the air. There are four significant TTHM (chloroform, bromoform, bromodichloromethane, and dibromochloromethane) potentially found in disinfected drinking water and their combined concentration is referred to as total TTHM.

We will continue to monitor the public drinking water supply for all regulated inorganic substances, synthetic organics, volatile organic compounds (vocs), Total Coliform, e.coli bacteria, unregulated (secondary) substances, organic disinfection byproducts, radionuclides, as well as lead and copper. Our team is committed to providing clean, safe water. As stewards of this valuable resource, we take our job to protect public health and safety seriously. Our team of 30+ professionals work around the clock to provide reliable, cost-effective, high-quality water service that protects public health, promotes environmental stewardship, maintains customer confidence, and supports economic development and sustainability.
