What Makes Tolland's Water Unique?
Local geology and source profile
Tolland, Connecticut, in Capitol Planning Region — a Capitol Planning Region town adjacent to Ellington and Vernon in north-central Connecticut — receives its water from the Tolland Water Division, drawing from local Tolland County reservoirs through the north-central Connecticut distribution.
The moderately soft 73 mg/L hardness and TDS of 166.2 mg/L reflect the north-central Connecticut watershed's mixed Triassic Hartford Basin and New England crystalline character — slightly harder than the southeast Connecticut communities (Ledyard: 22 mg/L) due to the Hartford Basin calcareous redbed input. The Tolland watershed at the Capitol Planning Region crosses both the Triassic Hartford Basin — Triassic New Haven Arkose (calcareous redbed arkose — primary hardness contributor at the Basin margin) and Precambrian crystalline basement (insoluble). The mixed Triassic calcareous and crystalline insoluble input produces the moderately soft north-central Connecticut supply.
At 73 mg/L, Tolland's water is moderately soft — light scale forms slowly in appliances, dishwashers remain efficient, and bathroom fixtures need occasional cleaning. Semi-annual descaling is appropriate. The PFAS level of 9.6 ppt is elevated — Bradley International Airport (Windsor Locks — AFFF, the dominant north-central Connecticut PFAS source) and the Connecticut Pratt & Whitney industrial corridor (Middletown-Windsor industrial PFAS legacy) contribute to Tolland's elevated readings.
Geology & Source: Tolland in Capitol Planning Region draws from the Tolland Water Division on local reservoirs (Connecticut Capitol Planning Region, north-central Connecticut) — the watershed drains the New England Upland (Triassic Hartford Basin New Haven Arkose — slightly calcareous, Precambrian crystalline — insoluble) — Connecticut Capitol Planning Region Triassic Hartford Basin watershed produces moderately soft water at 73 mg/L with TDS 166.2 mg/L.
