What Makes Roxbury Crossing's Water Unique?
Local geology and source profile
Roxbury Crossing, Massachusetts, in Suffolk County — a Suffolk County (Boston) neighborhood adjacent to Mission Hill and Roxbury in south-central Boston — receives its water from the Massachusetts Water Resources Authority (MWRA), drawing from the Quabbin Reservoir and Wachusett Reservoir (central Massachusetts) through the Boston metro distribution.
The soft 49.5 mg/L hardness and low TDS of 91.7 mg/L are consistent with the MWRA Boston metro supply (Boston metro: ~50-55 mg/L) — reflecting the soft Quabbin-Wachusett crystalline watershed character. The Quabbin and Wachusett Reservoirs drain central Massachusetts — Precambrian Ware Schist (insoluble), Ordovician Brimfield Schist (insoluble), and Devonian New Hampshire Plutonic Suite granite (insoluble). The entirely insoluble central Massachusetts crystalline basement produces the soft Boston metro supply.
At 49.5 mg/L, Roxbury Crossing's water is soft — light scale forms very slowly in appliances, dishwashers are highly efficient, and bathroom fixtures need minimal cleaning. Annual descaling is sufficient. The PFAS level of 6.5 ppt warrants a certified reverse osmosis drinking water filter — Hanscom Air Force Base (Middlesex County — AFFF, a primary Massachusetts PFAS source), South Weymouth Naval Air Station (Norfolk County — AFFF, legacy contamination), and the Boston metro industrial PFAS complex contribute to Roxbury Crossing's elevated readings.
Geology & Source: Roxbury Crossing in Suffolk County draws from the MWRA on the Quabbin and Wachusett Reservoirs (Suffolk County, Boston) — the Quabbin-Wachusett drains Precambrian and Ordovician central Massachusetts granite and gneiss (insoluble) — Massachusetts Suffolk County MWRA Quabbin-Wachusett crystalline watershed produces soft water at 49.5 mg/L with TDS 91.7 mg/L.
