What Makes Billerica's Water Unique?
Local geology and source profile
Billerica, Massachusetts, in Middlesex County — a major Middlesex County suburban community north of Boston, a growing outer Boston suburban community adjacent to Lowell, Chelmsford, and Burlington, home of several major defense technology corporations (Billerica is part of Massachusetts's technology corridor along Route 3), and a diverse Middlesex County community — draws its municipal water supply from the Fort Pond Brook watershed via the Town of Billerica Water Division. Water hardness in Billerica measures 28 mg/L — classified as very soft.
Billerica's exceptional softness reflects the north-central Middlesex County watershed's calcareous-poor crystalline geology. The Fort Pond Brook and Concord River tributaries at Billerica drain: the Andover Granite (a major Devonian calcareous-poor pink granite pluton of Middlesex County — one of the dominant bedrock units of the north Middlesex County upland); Precambrian calcareous-poor Merrimac Spur gneiss (calcareous-poor crystalline basement); and Post-Acadian calcareous-poor glacial outwash of the Merrimack Lowland. The calcareous-poor granite terrain and Town of Billerica treatment produce the exceptionally soft 28 mg/L.
With hardness at 28 mg/L, Billerica residents enjoy exceptionally soft water with virtually no scale challenges. Town of Billerica Water Division consistently delivers water meeting all Massachusetts MassDEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Concord River and Fort Pond Brook watershed via the Town of Billerica Water Division — the Middlesex County north-central Massachusetts Merrimack Lowland (Devonian calcareous-poor Billerica area granite and Andover Granite pluton — calcareous-poor crystalline terrain of the Middlesex County upland); very soft supply at 28 mg/L — reflecting the calcareous-poor Middlesex County granite watershed.
