What Makes North Bellport's Water Unique?
Local geology and source profile
North Bellport, New York, in Suffolk County — a Suffolk County hamlet adjacent to Bellport and Medford in south-central Suffolk County on Long Island — receives its water from the Suffolk County Water Authority, drawing from the Long Island sole-source aquifer through the south-central Long Island distribution.
The hard 175 mg/L hardness and TDS of 463.5 mg/L are notably higher than typical Long Island values — North Bellport's aquifer zone near the Harbor Hills moraine contains calcareous Pleistocene glacial deposits with significantly more carbonate material than the typical Cretaceous sand aquifer zones to the west (compare Bellport NY: 172/455 in Suffolk County comparable; Medford NY: 178/471 in Suffolk County comparable; North Bellport consistent hard from the same Suffolk County Long Island Cretaceous moraine supply). The Long Island aquifer at North Bellport — Cretaceous Magothy Formation (insoluble — dilutant), Pleistocene Harbor Hills moraine (calcareous — primary hardness contributor), and Holocene south shore deposits (slightly calcareous — TDS contributor).
At 175 mg/L with TDS 464, North Bellport's water is hard — scale builds in appliances and fixtures. Quarterly descaling is appropriate. The PFAS level of 8.3 ppt is elevated — a certified drinking water filter is recommended — the Suffolk County Long Island industrial and military (Brookhaven National Laboratory) legacy contributes to North Bellport's elevated PFAS readings. Review SCWA's annual report.
Geology & Source: North Bellport in Suffolk County draws from the Suffolk County Water Authority on the Long Island aquifer (Suffolk County, south-central New York) — the Long Island aquifer at North Bellport is developed in Cretaceous Magothy Formation (insoluble) and Pleistocene Harbor Hills moraine (calcareous) — New York Suffolk County Long Island Cretaceous moraine supply produces hard water at 175 mg/L with TDS 463.5 mg/L.
