What Makes North New Hyde Park's Water Unique?
Local geology and source profile
North New Hyde Park, New York, in Nassau County — an unincorporated Nassau County community adjacent to New Hyde Park and Garden City Park in western Nassau County, Long Island — receives its water from Nassau County utilities, drawing from the Long Island Aquifer system (Nassau County) through the western Long Island distribution.
The moderately soft 69.5 mg/L hardness and low TDS of 108.5 mg/L reflect the western Nassau County Long Island Aquifer's predominantly soft glacial outwash character — consistent with other Nassau County communities (Elmont: ~68 mg/L; Mineola: ~72 mg/L). The Long Island Aquifer at Nassau County is developed in Pleistocene glacial outwash (slightly calcareous, derived from New England crystalline — minor hardness contributor), Cretaceous Magothy Aquifer (insoluble sand — primary aquifer), and Cretaceous Lloyd Aquifer (insoluble). The predominantly insoluble Cretaceous sand and slightly calcareous Pleistocene outwash produce the moderately soft supply.
At 69.5 mg/L, North New Hyde Park'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 3.4 ppt warrants a certified drinking water filter — the Nassau County western Long Island industrial corridor, Mitchel Field (Nassau County — historic AFFF use), and the Long Island groundwater PFAS background from multiple legacy contamination sites contribute to North New Hyde Park's readings.
