What Makes West Babylon's Water Unique?
Local geology and source profile
West Babylon, New York, in Suffolk County on the south shore of Long Island — a major Long Island south shore community adjacent to Bay Shore and Copiague, a diverse working-class and middle-class Suffolk County community with significant Caribbean-American, Latin American, and Italian-American populations, home of Belmont Lake State Park and the Babylon Riding Center — draws its municipal water supply from the Long Island Magothy Aquifer via the Suffolk County Water Authority (SCWA). Water hardness in West Babylon measures 140.5 mg/L — classified as moderately hard.
West Babylon's moderate hardness reflects the west Suffolk County south shore aquifer characteristics. The Magothy Aquifer at West Babylon–Suffolk County is hosted in the Cretaceous Magothy Formation (moderately calcareous sandy marine formation — the main Long Island aquifer, with some calcareous cemented layers and shell hash contributing dissolved calcium). The Pleistocene glacial outwash overlying the Magothy is predominantly calcareous-poor quartz–feldspar sand (from the Laurentide Ice Sheet Ronkonkoma Moraine), but the underlying Magothy Formation at the West Babylon depth has more calcareous character. The SCWA well fields at West Babylon produce the moderate 140.5 mg/L.
At 140.5 mg/L, West Babylon residents encounter moderate-to-hard scale accumulation. Monthly cleaning with citric acid solution is recommended for faucet aerators and showerheads. Suffolk County Water Authority consistently delivers water meeting all New York State DOH and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Nassau–Suffolk Magothy Aquifer via the Suffolk County Water Authority (SCWA) — the Suffolk County west Long Island south shore (Pleistocene glacial outwash plain — the Long Island outwash plain quartz–feldspar sand); moderately hard supply at 140.5 mg/L — reflecting the west Suffolk County south shore outwash aquifer characteristics.
