The bill amends the Safe Drinking Water Act Assessment Program in Massachusetts, which mandates an annual report from the SDWA Assessment Advisory Committee to oversee the Massachusetts Department of Environmental Protection's (MassDEP) Drinking Water Program (DWP). The 2024 report emphasizes initiatives such as the Lead and Copper Rule Revisions (LCCR), requiring public water systems to create a Service Line Inventory to identify lead service lines, and the Water Smart Program, which provides free lead testing for schools and childcare facilities. It also addresses cybersecurity measures to safeguard public water systems and ongoing efforts to manage Per- and Polyfluoroalkyl Substances (PFAS), with 175 public water suppliers reporting PFAS levels exceeding the Maximum Contaminant Level.

Additionally, the bill outlines various support measures to enhance the compliance and operational efficiency of Public Water Suppliers (PWS). These include biweekly regulatory updates, an online template for Consumer Confidence Report (CCR) compliance, and technical assistance for small system operators. The bill also introduces new training courses approved by the Board of Certification of Operators of Drinking Water Supply Facilities, focusing on cybersecurity and emergency response, and offers free cybersecurity assessments for PWS. Collaboration with the Massachusetts Department of Public Health and the U.S. Geological Survey is highlighted to address lead contamination and improve overall drinking water safety.
