What Makes North Bellmore's Water Unique?
Local geology and source profile
North Bellmore, New York, in Nassau County — a suburban Nassau County community in the Town of Hempstead in central Nassau County, part of the densely populated south Shore Long Island residential corridor — receives its municipal water from the Nassau County Department of Public Works or the Bellmore Water District, which draws from the Upper Glacial Aquifer (Pleistocene outwash) and the Magothy Aquifer (Cretaceous coastal plain sand) through Nassau County's extensive production well network.
The moderately hard 174 mg/L hardness and elevated TDS of 460.8 mg/L are consistent with the Nassau County central SCWA/DPW supply zones — reflecting the deeper Magothy Aquifer production in Nassau County's central corridor. The Nassau County aquifer system (the layered Upper Glacial, Magothy, and Lloyd aquifer sequence) in the Town of Hempstead corridor produces moderately hard water with elevated TDS from the Cretaceous coastal plain marine sediment mineral matrix, similar to the East Northport and Lake Ronkonkoma Suffolk County profiles but in the Nassau County southern shore zone.
At 174 mg/L, North Bellmore'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 8.3 ppt warrants a certified drinking water filter — the Mitchel Field legacy (former USAF Mitchel Field in Garden City, Nassau County — a documented AFFF site), the Grumman Bethpage PFAS plume, and Long Island's defense-aviation industrial PFAS complex contribute to North Bellmore's PFAS readings.
Geology & Source: North Bellmore in Nassau County draws from Nassau County Department of Public Works or the Bellmore Water District on the Upper Glacial Aquifer and Magothy Aquifer (Long Island coastal plain) — Nassau County's aquifer system accesses Pleistocene outwash and Cretaceous Magothy Formation calcareous sand — Long Island aquifer produces moderately hard water at 174 mg/L with elevated TDS 461 mg/L in this Nassau County New York community.
