What Makes Claremont's Water Unique?
Local geology and source profile
Claremont, New Hampshire, in Sullivan County — the Sullivan County seat adjacent to Newport and Windsor VT on the Sugar River in west-central New Hampshire — receives its water from the City of Claremont Water, drawing from the Sugar River watershed reservoir (Sullivan County) through the west-central New Hampshire distribution.
The soft 70.5 mg/L hardness and TDS of 173.4 mg/L reflect the west-central New Hampshire Sullivan County Sugar River supply's soft character — the Precambrian Bronson Hill anticlinorium gneiss and Ordovician volcanic formations contribute insoluble dilution with minimal calcareous contact, typical of the New Hampshire interior highland communities (compare Windham NH: 66.5 mg/L on glacial outwash; Fort Drum NY: 68.5 mg/L). The Sugar River watershed at Sullivan County — Precambrian Bronson Hill gneiss (insoluble — primary dilutant), Ordovician Ammonoosuc Volcanics (insoluble — secondary dilutant), and Pleistocene glacial outwash (slightly calcareous — minor hardness contributor).
At 70.5 mg/L, Claremont's water is soft — scale forms very slowly in appliances, dishwashers remain efficient, and no softening is needed. Annual descaling is appropriate. The PFAS level of 8.0 ppt warrants a certified drinking water filter — the Sullivan County west-central New Hampshire industrial corridor contribute to Claremont's elevated PFAS readings.
Geology & Source: Claremont in Sullivan County draws from the City of Claremont Water on the Sugar River watershed reservoir (Sullivan County, west-central New Hampshire) — the Sugar River watershed at Sullivan County drains Precambrian Bronson Hill anticlinorium gneiss (insoluble) and Ordovician Ammonoosuc Volcanics (insoluble) — New Hampshire Sullivan County Sugar River Precambrian-Ordovician insoluble supply produces soft water at 70.5 mg/L with TDS 173.4 mg/L.
