Amherst Center Water Hardness & Quality Report (2026)

Amherst Center, Massachusetts, in Hampshire County — an unincorporated community and the center of Amherst, a college town in the Pioneer Valley of western Massachusetts, home of UMass Amherst, Amherst College, and Hampshire College — receives its municipal water from the Amherst Water Division, drawing from Atkins Reservoir and East Street Reservoir in the Pelham Hills east of Amherst.

The soft 70.5 mg/L hardness and TDS of 147.4 mg/L reflect the Pelham Hills watershed's crystalline rock character. The Atkins Reservoir and East Street Reservoir drain the Pelham Dome — a Precambrian gneiss and quartzite massif (Pelham Gneiss, Devonian Erving Formation schist, and Monson Gneiss — all insoluble silicate metamorphic rock). The result is the relatively soft water characteristic of the crystalline upland reservoirs of western Massachusetts, somewhat harder than the Quabbin-supplied communities but softer than the carbonate-influenced Pioneer Valley floor groundwater.

At 70.5 mg/L, Amherst Center's water is soft — essentially no scale forms, soap lathers abundantly, and appliances maintain good efficiency. Annual descaling is sufficient. The PFAS level of 8.0 ppt warrants a certified drinking water filter — the Westover Air Reserve Base (Chicopee, Hampden County — a documented PFAS AFFF site in the Connecticut River-Hampshire County watershed), the Barnes Municipal Airport (Westfield PFAS source), and the Pioneer Valley PFAS industrial background contribute to Amherst's elevated readings.
