Weymouth, MA receives a water quality score of 85/100 (Grade B) based on EPA Safe Drinking Water Information System (SDWIS) compliance data for 2 public water systems serving the area.
Weymouth's water quality is above the national average, with strong compliance records and low contaminant levels. Residents generally receive clean, safe tap water that meets EPA standards.
Weymouth's score of 85 is 11 points above the Massachusetts state average of 74, and above the nationwide average of roughly 78/100 across all U.S. states.
As a mid-sized coastal community in Massachusetts, Weymouth relies on a couple of distinct water systems operating within the Northeast's typically dense and aging utility network. The local supply generally meets solid standards, though the regional footprint of older infrastructure suggests that tap quality can sometimes be influenced by individual household service lines. For homebuyers or current residents, this means that while the municipal supply is broadly reliable, checking the composition of property-specific plumbing remains a practical step.
