What Makes Concord's Water Unique?
Local geology and source profile
Concord, New Hampshire, the Merrimack County seat and state capital — a major New Hampshire governmental and financial hub on the Merrimack River, home of the New Hampshire State House (the oldest statehouse in which both chambers still meet in their original chambers), Saint Paul's School (one of New England's premier boarding schools), and the New Hampshire Motor Speedway (a major NASCAR Cup Series venue) — draws its municipal water supply from Penacook Lake and Turkey Pond via the City of Concord Water Division. Water hardness in Concord measures 77 mg/L — classified as moderately soft.
Concord's moderate softness reflects the Merrimack County watershed's calcareous-poor New England Upland geology. The Penacook Lake watershed drains the New Hampshire Uplands — predominantly Devonian Kinsman Granite and Concord Granite (calcium-poor Paleozoic granite of the New Hampshire Uplands) and Proterozoic–Ordovician metamorphic gneiss (calcareous-poor Merrimack Valley crystalline terrain). The City of Concord's reservoir watershed from this calcareous-poor crystalline geology, supplemented by effective water treatment, produces the moderate 77 mg/L — typical for a New Hampshire state capital supply.
With hardness at 77 mg/L, Concord residents enjoy moderately soft water with minimal scale challenges. City of Concord Water Division consistently delivers water meeting all New Hampshire DES and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Penacook Lake and Turkey Pond watershed via the City of Concord Water Division — the Merrimack County New Hampshire Merrimack Valley (Proterozoic–Paleozoic calcareous-poor granitic and metamorphic New England Upland); moderately soft supply at 77 mg/L in Merrimack County.
