Palmer Water Hardness & Quality Report (2026)

Palmer, Massachusetts, in Hampden County — a Hampden County town adjacent to Ware and Monson in the Pioneer Valley of western Massachusetts, at the junction of the Chicopee River and the Swift River — receives its municipal water from the Palmer Water Division, drawing from Cushman Reservoir or similar Chicopee River watershed reservoirs in Hampden County.

The soft 51.5 mg/L hardness and low TDS of 96.5 mg/L reflect the west Massachusetts Precambrian upland supply. The Palmer area reservoir drains the Central Massachusetts Upland — Precambrian Pelham Dome gneiss (insoluble crystalline), Silurian Merrimack Group schist and quartzite (insoluble metamorphic), and Triassic Hartford Basin sandstone (slightly calcareous — minor contributor near the Connecticut River). The predominantly insoluble crystalline bedrock produces the soft water characteristic of the western Massachusetts supply.

At 51.5 mg/L, Palmer's water is soft — essentially no scale forms, soap lathers abundantly, and appliances maintain good efficiency. Annual descaling is sufficient. The PFAS level of 6.7 ppt warrants a certified drinking water filter — the Westover Air Reserve Base (Chicopee, Hampden County — AFFF in the Chicopee River watershed), Hanscom AFB and Connecticut River valley PFAS corridor, and the western Massachusetts PFAS background contribute to Palmer's elevated readings.
