Torrington Water Hardness & Quality Report (2026)

Torrington, Connecticut, the Litchfield County seat — the largest city in Litchfield County (Torrington is the only substantial urban center in the otherwise rural Litchfield Hills region of northwest Connecticut — the county seat and main commercial hub of Litchfield County), historically a major brass and needle manufacturing city (Torrington was a significant center of the Connecticut Naugatuck Valley brass industry — the American Brass Company and Torrington Company were among major employers; the Torrington Company, once the world's largest needle roller bearing manufacturer, operated for nearly a century), a diverse Litchfield County community, and the birthplace of John Brown (the famous abolitionist who led the Harpers Ferry raid in 1859, considered a pivotal precursor to the Civil War, was born in Torrington in 1800) — draws its municipal water supply from the Naugatuck River via the Torrington Water Company. Water hardness in Torrington measures 74.5 mg/L — classified as moderately soft.

Torrington's moderate softness reflects the Litchfield Hills watershed's calcareous-poor crystalline geology (essentially the same watershed as West Torrington at 26.5 mg/L, with moderate treatment variation). The Naugatuck River and Highland Lake at Torrington drain the Precambrian–Paleozoic Berkshire Massif gneiss and Hartland Terrane schist (highly calcareous-poor northwest Connecticut crystalline basement), producing the moderate 74.5 mg/L.

With hardness at 74.5 mg/L, Torrington residents enjoy moderately soft water. Torrington Water Company consistently delivers water meeting all Connecticut DEEP and EPA Safe Drinking Water Act requirements.
