What Makes Fort Salonga's Water Unique?
Local geology and source profile
Fort Salonga, New York, in Suffolk County — a Suffolk County hamlet adjacent to Northport and Kings Park on the north shore of Long Island — receives its water from the Suffolk County Water Authority, drawing from the Magothy and Upper Glacial aquifers through the north-shore Long Island distribution.
The hard 135 mg/L hardness and TDS of 302.3 mg/L reflect the Suffolk County supply's hard Long Island north-shore aquifer character — the Cretaceous Magothy Formation and Pleistocene Upper Glacial aquifer are sandy-calcareous formations in the Long Island Coastal Plain; the Fort Salonga area wells draw from the deep Magothy aquifer on the north shore, producing moderately higher hardness and TDS than the south-shore shallow aquifer zones (compare Northport NY: 131/293 in Suffolk County comparable; Kings Park NY: 138/311 in Suffolk County comparable; Fort Salonga consistent hard from the same Suffolk County Magothy aquifer Cretaceous supply). The Long Island aquifer system — Cretaceous Magothy Formation (sandy insoluble — primary dilutant), Pleistocene Upper Glacial aquifer (sandy calcareous — primary hardness contributor), and Quaternary Long Island glaciolacustrine deposit (calcareous — TDS contributor).
At 135 mg/L with TDS 302, Fort Salonga's water is hard — scale builds in appliances. Quarterly descaling is appropriate. The PFAS level of 6.5 ppt warrants a certified drinking water filter. Review the Suffolk County Water Authority's annual water quality report.
Geology & Source: Fort Salonga in Suffolk County draws from the Suffolk County Water on the Magothy/Upper Glacial aquifer (Suffolk County, north-shore Long Island) — the Long Island Coastal Plain at Suffolk County draws from Cretaceous Magothy Formation (sandy insoluble) and Pleistocene Upper Glacial aquifer (sandy calcareous) — New York Suffolk County Magothy aquifer Cretaceous supply produces hard water at 135 mg/L with TDS 302.3 mg/L.
