What Makes Enfield's Water Unique?
Local geology and source profile
Enfield, Connecticut, in Hartford County on the Connecticut River — a major Greater Hartford north suburban community, historical site of the first significant industrial revolution manufacturing in New England (Enfield Falls Canal, 1829), a diverse Hartford County community with a significant Puerto Rican and African-American population, and adjacent to the Enfield Outlet Mall corridor on I-91 — draws its municipal water supply from the Shallowbrook Reservoir and Metropolitan District Commission (MDC) Hartford supply via the Town of Enfield Water Division. Water hardness in Enfield measures 76 mg/L — classified as moderately soft.
Enfield's moderate softness reflects the Hartford County watershed's moderately soft Connecticut Valley geology. The Enfield reservoir watershed drains the Connecticut Eastern Uplands and the Hartford Basin Triassic terrain — the Jurassic Portland Formation arkose (moderately calcareous, with some feldspar weathering contributing calcium) and the Proterozoic–Paleozoic New England Upland crystalline granite (calcareous-poor). The MDC Hartford system blends both sources, and Enfield's effective water treatment produces the moderate 76 mg/L — typical for the northern Hartford metro supply zone.
With hardness at 76 mg/L, Enfield residents enjoy moderately soft water with minimal scale challenges. Town of Enfield Water Division consistently delivers water meeting all Connecticut DEEP and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Shallowbrook and Shenipsit reservoirs (Hockanum River watershed) via the Metropolitan District Commission (MDC) Hartford system and the Town of Enfield Water Division — the Hartford County Connecticut River Valley (Triassic–Jurassic Hartford Basin arkose + New England Upland calcareous-poor granite); moderately soft supply at 76 mg/L in Hartford County.
