Revere Water Hardness & Quality Report (2026)

Revere, Massachusetts, in Suffolk County on Revere Beach (the first public beach in the United States, established 1896) — a densely urban coastal Boston suburb historically known as a resort destination for working-class Boston immigrants, now with a large Somali-American, Brazilian-American, and Central American community — draws its municipal water supply from the Quabbin Reservoir and Wachusett Reservoir via the Massachusetts Water Resources Authority (MWRA) metropolitan Boston distribution system. Water hardness in Revere measures 18.5 mg/L — classified as extremely soft, one of the softest municipal supplies in the United States.

Revere's extraordinary softness reflects the MWRA's Quabbin–Wachusett reservoir supply from western Massachusetts' calcium-poor crystalline watershed. The Quabbin Reservoir (Swift River–Connecticut River watershed — draining the Pelham Dome and Bronson Hill anticlinorium Cambrian and Precambrian crystalline terrain of western Massachusetts — the Pelham Gneiss, Amherst Gneiss, and the Northfield–Orange schist belts: calcium-poor crystalline terrain) produces extremely soft water. After blending and MWRA treatment, the supply reaches the north Boston coastal communities as the extremely soft 18.5 mg/L at Revere Beach — nearly mineral-free water at the household tap.

With hardness at 18.5 mg/L, Revere residents experience essentially no scale challenges whatsoever. MWRA consistently delivers water meeting all Massachusetts MassDEP and EPA Safe Drinking Water Act requirements.
