East Concord Water Hardness & Quality Report (2026)

East Concord, New Hampshire, a neighborhood/village in Concord — the New Hampshire state capital, one of the smallest state capitals in the US by population, a historically significant New Hampshire governmental and civic community known for the New Hampshire State House (the oldest state capitol in the US in which the legislature still meets in its original chambers, built 1816–1819), the McAuliffe-Shepard Discovery Center (honoring Christa McAuliffe, the first civilian selected for the Space Shuttle Challenger crew), and the birthplace of Mary Baker Eddy (founder of Christian Science) — draws its municipal water supply from Penacook Lake and Turkey Pond via the City of Concord Water Division. Water hardness in East Concord measures 27 mg/L — classified as very soft.

East Concord's very soft supply reflects the central New Hampshire granite watershed's calcareous-poor geology. The Concord water supply reservoirs drain: the New Hampshire Merrimack Valley Uplands (Devonian Concord Granite and New Hampshire granodiorite and gneiss — the crystalline core of the New Hampshire Highlands, highly calcareous-poor). New Hampshire's crystalline granite terrain — the White Mountain Batholith and the Concord–Canterbury granite — produces some of the softest reservoir watershed recharge in New England. The very soft 27 mg/L at East Concord reflects this calcareous-poor granite watershed.

With hardness at 27 mg/L, East Concord residents enjoy exceptionally soft water with virtually no scale challenges. City of Concord Water Division consistently delivers water meeting all New Hampshire DES and EPA Safe Drinking Water Act requirements.
