What Makes Meriden's Water Unique?
Local geology and source profile
Meriden, Connecticut, in New Haven County — a historic industrial city in central Connecticut, known for the 'Silver City' designation from its peak as the silverware manufacturing capital of the United States — draws its municipal water supply from the East Berlin Reservoir and Meriden Reservoir system via the City of Meriden Water Division and South Central Connecticut Regional Water Authority (RWA). Water hardness in Meriden measures 52.5 mg/L — classified as very soft.
Meriden's very soft supply reflects the central Connecticut Hartford Basin trap rock geology. The Meriden watershed in central New Haven County drains: the Metacomet Ridge — the iconic Jurassic Talcott Basalt and Hampden Basalt (the northernmost expression of the CAMP Central Atlantic Magmatic Province flood basalt flows — calcium-poor basalt of the Hartford Basin rift system); the Triassic New Haven Arkose and Portland Formation (calcareous Triassic rift basin sandstone — moderate calcareous contribution); and some Mesoproterozoic Connecticut River Valley gneiss (calcium-poor). The dominant Jurassic basalt (Chauncey Peak, Lamentation Mountain, East Rock — all part of the Metacomet Ridge in the Meriden area) contributes minimal dissolved calcium, producing the very soft 52.5 mg/L.
With hardness at 52.5 mg/L, Meriden residents enjoy very soft water with minimal scale challenges. 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 East Berlin–Meriden Reservoir system via the City of Meriden Water Division and South Central Connecticut Regional Water Authority (RWA) — the Hartford Basin Triassic–Jurassic basalt trap rock (Talcott and Hampden Basalt) and Triassic Portland Arkose of New Haven County; very soft supply at 52.5 mg/L in New Haven County.
