What Makes Floral Park's Water Unique?
Local geology and source profile
Floral Park, New York, in Nassau County — a Nassau County village adjacent to New Hyde Park and Queens at the Nassau-Queens border on the north shore of Long Island — receives its municipal water from the Nassau County Department of Public Works, drawing from the Long Island Aquifer (Magothy Formation wells, Nassau County) — unlike western Nassau communities that receive NYCDEP surface water.
The moderately hard 123 mg/L hardness and TDS of 260.2 mg/L are significantly harder than the western Nassau NYCDEP communities (Roosevelt: 70 mg/L; Bellmore: 78.5 mg/L), confirming Floral Park draws from the Long Island Aquifer rather than NYC surface water. The Long Island Aquifer at Nassau County is developed in Cretaceous Lloyd Sand (moderately calcareous), Cretaceous Magothy Formation (calcareous glacial outwash), and Pleistocene Upper Glacial aquifer (glacially ground carbonate and siliceous). The calcareous glacial outwash produces the moderately hard north Nassau supply.
At 123 mg/L, Floral Park's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 5.9 ppt warrants a certified drinking water filter — the Nassau County Long Island industrial corridor and the Long Island Aquifer PFAS background contribute to Floral Park's readings.
Geology & Source: Floral Park in Nassau County draws from Nassau County DWP on the Long Island Aquifer (Nassau County, northwest Long Island) — the Long Island Aquifer is developed in Cretaceous Lloyd Sand and Pleistocene Magothy Formation (calcareous glacial sand and gravel — moderately calcareous) — New York Nassau County Long Island Aquifer Pleistocene-Cretaceous calcareous supply produces moderately hard water at 123 mg/L with TDS 260.2 mg/L in this Nassau County New York village.
