What Makes Huntington's Water Unique?
Local geology and source profile
Huntington, New York, in Suffolk County — a Suffolk County town adjacent to Cold Spring Harbor and Melville on the north shore of Long Island, a historic north shore community with a charming village center — receives its municipal water from the Suffolk County Water Authority (SCWA), drawing from the Long Island Aquifer system (Upper Glacial and Magothy Aquifers, north Suffolk County) through SCWA wells.
The soft 80 mg/L hardness and TDS of 133.4 mg/L reflect the Long Island glacial aquifer's insoluble sand character. The Long Island Aquifer in north Suffolk County is developed in Pleistocene glacial outwash and moraine deposits (Ronkonkoma and Harbor Hill Moraines — quartz-rich glacial sand derived from the New England crystalline), the Cretaceous Magothy Formation (fine quartz sand), and the Cretaceous Lloyd Formation (deep aquifer). The predominantly siliceous glacial sand produces the soft water characteristic of Long Island supplies.
At 80 mg/L, Huntington's water is soft — essentially no scale forms, soap lathers abundantly, and appliances maintain good efficiency. Annual descaling is sufficient. The PFAS level of 3.9 ppt warrants a certified drinking water filter — the Grumman Aerospace legacy (Bethpage, Nassau County — one of the largest PFAS plumes on Long Island in the Nassau-Suffolk aquifer), the Calverton Naval Weapons Industrial Reserve Plant (Suffolk County — AFFF contamination), and the Long Island PFAS background contribute to Huntington's readings.
Geology & Source: Huntington in Suffolk County draws from the Suffolk County Water Authority on the Long Island Aquifer (Nassau-Suffolk Glacial Aquifer, Suffolk County) — the Long Island Aquifer is developed in Pleistocene glacial outwash sand (Ronkonkoma Moraine, Lloyd Harbor) — New York Long Island Pleistocene glacial outwash aquifer produces soft water at 80 mg/L with TDS 133.4 mg/L in this Suffolk County New York town.
