What Makes Branford's Water Unique?
Local geology and source profile
Branford, Connecticut, in New Haven County — a major south Connecticut coastal community (Branford is a significant New Haven County town — a south Connecticut shoreline community on Long Island Sound east of New Haven; Branford is known for its charming historic downtown Green (one of the most attractive town greens in coastal Connecticut), its beautiful Thimble Islands (a cluster of over 100 small granite islands in Long Island Sound just off the Branford coast — the Thimble Islands are one of the most distinctive and picturesque island communities in New England, accessible by ferry), and its excellent Long Island Sound shoreline access), a diverse New Haven County community with a primarily working-class and middle-class suburban and coastal professional population, home of the Foote School (a significant independent school in the New Haven area) and various coastal research facilities, adjacent to East Haven and Guilford in the south Connecticut Sound corridor, and a community with a strong maritime and coastal identity — draws its municipal water supply via the South Central Connecticut Regional Water Authority. Water hardness in Branford measures 77.5 mg/L — classified as moderately soft.
Branford's moderate softness reflects the south Connecticut coastal watershed's calcareous-poor geology. The Farm River watershed drains the Triassic Hartford Basin arkose (calcareous-poor) and Precambrian Connecticut gneiss (calcareous-poor). SCCRWA treatment produces the moderately soft 77.5 mg/L.
With hardness at 77.5 mg/L, Branford residents enjoy moderately soft water. South Central Connecticut Regional Water Authority consistently delivers water meeting all Connecticut DEEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Farm River and Lake Saltonstall watershed via the South Central Connecticut Regional Water Authority (SCCRWA) — the New Haven County south Connecticut coast Branford corridor (Triassic calcareous-poor Hartford Basin arkose and Precambrian calcareous-poor Connecticut gneiss — the calcareous-poor south Connecticut coastal watershed; SCCRWA effective treatment); moderately soft supply at 77.5 mg/L in New Haven County.
