Massachusetts Tap Water Quality

EPA water quality data for 150 community water systems serving 1,037,474+ people in Massachusetts. Click any system to see violations, lead testing results, and a safety grade.

Massachusetts utilities source water primarily from protected surface reservoirs, including the Quabbin and Wachusett Reservoirs that serve metro Boston. PFAS contamination near military installations and fire training sites has prompted aggressive state-level standards. Older cities like Worcester and Springfield face ongoing lead service line replacement.
