Framingham Center Water Hardness & Quality Report (2026)

Framingham Center, Massachusetts — the historic town center of Framingham, Massachusetts, at the junction of Routes 9 and 30 in Middlesex County — draws its municipal water supply from the same Cochituate Reservoir and Framingham Reservoir system as the broader City of Framingham via the Framingham Water Division, treating MetroWest reservoir water for the entire Framingham community including the Center village. Water hardness in Framingham Center measures 90 mg/L — classified as moderately soft, identical to the broader Framingham supply.

Framingham Center's soft supply reflects the same Cochituate–Framingham reservoir watershed geology as all of Framingham. The reservoirs draw from the MetroWest Massachusetts crystalline bedrock — the Proterozoic Dedham Granite (calcium-poor granitic basement of southeastern New England), the Milford Pink Granite (a distinctive Devonian–Carboniferous biotite granite), and the Ordovician Marlboro Formation (quartzite and phyllite). These hard crystalline rocks dissolve very slowly, producing naturally soft reservoir water. The 90 mg/L reflects trace calcareous input from glacial till calcium leaching in the Cochituate watershed soils and minor calcareous interbeds in the Marlboro Formation.

With hardness at 90 mg/L, Framingham Center residents enjoy moderately soft water with minimal scale challenges. Framingham Water Division consistently delivers water meeting all Massachusetts MassDEP and EPA Safe Drinking Water Act requirements.
