What Makes Plainville's Water Unique?
Local geology and source profile
Plainville, Connecticut, in the Capitol Planning Region — a central Connecticut town adjacent to New Britain and Bristol in the Farmington River valley — receives its municipal water from the Plainville Water Division or the New Britain Water Department, drawing from the Shuttle Meadow Reservoir or the Farmington River (central Connecticut).
The very soft 41 mg/L hardness and TDS of 75.7 mg/L reflect the central Connecticut Farmington River watershed's predominantly crystalline geology. The Farmington River drains the Connecticut Western Highlands — Precambrian Berkshire Gneiss and Cambrian-Ordovician Taconic schist and marble (mostly insoluble metasedimentary crystalline), with only minor Triassic Hartford Basin calcareous input at lower elevations. The crystalline upland dominance produces the very soft supply.
At 41 mg/L, Plainville's water is very soft — essentially no scale forms, soap lathers very abundantly, and appliances maintain excellent efficiency. Annual descaling is sufficient. The PFAS level of 6.8 ppt warrants a certified drinking water filter — Southington industrial corridor PFAS, the New Britain manufacturing legacy, and the Farmington River watershed suburban PFAS background contribute to Plainville's elevated readings.
