What Makes Easton's Water Unique?
Local geology and source profile
Easton, Massachusetts, in Bristol County in southeastern Massachusetts between Brockton and Attleboro — a historic community of rolling countryside near the Ames Free Library and the North Easton civic buildings designed by H.H. Richardson — receives its municipal water from the Town of Easton Water Division through MWRA water from the Quabbin-Wachusett delivery system. The Massachusetts Water Resources Authority distributes water from the pristine Central Massachusetts reservoir system to member communities throughout the greater Boston and southeastern Massachusetts region.
The extremely soft 23.5 mg/L hardness and remarkably low TDS of 36.7 mg/L are characteristic of MWRA Quabbin Reservoir supply — one of the softest municipal water supplies in the United States. Quabbin Reservoir collects water from over 186,000 acres of protected watershed lands in central Massachusetts draining ancient Precambrian Proterozoic gneisses and granites of the Merrimack Terrane — crystalline rocks that have been stable for hundreds of millions of years and have no soluble carbonate minerals. MWRA has preserved this watershed in a near-pristine natural state, producing consistently ultra-soft water delivered to Easton via the Metropolitan delivery system.
At 23.5 mg/L, Easton's water is extremely soft — among the softest in the United States. Soap lathers with minimal product needed, appliances remain scale-free for years, and the water has a noticeably clean, light character. Annual descaling of kettles and coffee machines is more than sufficient. The primary consideration with this ultra-soft water is its potential corrosiveness at very low TDS — old home plumbing with lead solder joints or brass fixtures deserves attention. Flushing cold taps before morning use is recommended. The PFAS level of 4.7 ppt is moderate for southeastern Massachusetts — Bristol County's industrial history and the regional military presence contribute to the area's PFAS background despite the pristine source water.
Geology & Source: Easton in Bristol County is served by MWRA water through the Quabbin-Wachusett delivery system — Quabbin Reservoir collects water from the Central Massachusetts Highland watershed over Precambrian crystalline rocks with no carbonate content — pure crystalline highland terrain produces extremely soft water at 23.5 mg/L with near-zero TDS of 36.7 mg/L characteristic of the pristine MWRA supply.
