An Act to improve the review and regulation of emerging contaminants on public water systems

HD 2605 establishes a Science Advisory Board to evaluate emerging contaminants in Massachusetts public water systems. The board, composed of 13 members including government representatives and experts, must review peer-reviewed scientific studies to recommend safe drinking water levels (MCLG and MCL) and assess health risks and cost-effectiveness of regulations. This process requires public comment periods and independent reviews by MassDEP and a Small Business Advocacy Review panel before contaminants can be regulated. The bill directly affects all public water systems in Massachusetts by creating a standardized, science-based procedure for setting contaminant safety standards. It aims to ensure regulatory decisions are grounded in public health data while considering implementation costs.
