What Makes Woodmere's Water Unique?
Local geology and source profile
Woodmere, New York, in Nassau County — a Nassau County hamlet adjacent to Hewlett and Lawrence in the Five Towns area on the south shore of Long Island — receives its municipal water from the Nassau County Department of Public Works or local water district, drawing from the Long Island Aquifer (Upper Glacial Aquifer) through local well fields in south Nassau County.
The moderately soft 87.5 mg/L hardness and TDS of 152.8 mg/L are notably softer than north Nassau County readings (Massapequa Park: 168 mg/L) and north Suffolk (Kings Park: 161.5 mg/L). South Nassau County in the Five Towns area draws from the shallowest Pleistocene glacial outwash zones, which have less mineral contact time and less deep Cretaceous Magothy Formation contribution, producing softer water than the deeper aquifer zones used in central and north Nassau County.
At 87.5 mg/L, Woodmere's water is moderately soft — light scale forms slowly in appliances, dishwashers remain efficient, and bathroom fixtures need occasional cleaning. Semi-annual descaling is appropriate. The PFAS level of 4.3 ppt warrants a certified drinking water filter — the south Nassau Five Towns corridor, the Long Island MacArthur Airport drainage (south Suffolk), and the Nassau County residential PFAS background contribute to Woodmere's readings.
Geology & Source: Woodmere in Nassau County draws from the Nassau County DPW on the Long Island Aquifer (south Nassau County) — the aquifer is developed in Pleistocene glacial outwash and Cretaceous Lloyd Sand (insoluble quartz) — New York Long Island Pleistocene-Cretaceous aquifer produces moderately soft water at 87.5 mg/L with TDS 152.8 mg/L in this Nassau County New York hamlet.
