What Makes Long Beach's Water Unique?
Local geology and source profile
Long Beach, New York, in Nassau County — a major south Nassau County barrier island community (Long Beach is a barrier island city on the south shore of Nassau County, Long Island — one of the most densely populated barrier island cities in the United States, entirely surrounded by Reynolds Channel and the Atlantic Ocean), known as the 'City by the Sea' (Long Beach is one of the premier beach resort communities in the greater New York metro area — its long Atlantic shoreline beach is one of the most used public beaches in the New York metropolitan area), a diverse Nassau County community with a significant Jewish-American, Irish-American, and Hispanic-American population, and a community famous for its Long Beach Boardwalk (a notable south Nassau County beachfront promenade) — draws its municipal water supply from the Nassau County Atlantic Coastal Plain aquifer via the Long Beach Water Department. Water hardness in Long Beach measures 118.5 mg/L — classified as moderately hard.
Long Beach's moderate hardness reflects the Nassau County Atlantic Coastal Plain aquifer characteristics. The Magothy and Lloyd aquifer formations at Long Beach (Cretaceous calcareous-moderate sands and gravels) provide moderate mineral content. Long Beach Water Department treatment produces the moderate 118.5 mg/L.
At 118.5 mg/L, Long Beach residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended. Long Beach Water Department consistently delivers water meeting all New York State DEC and EPA Safe Drinking Water Act requirements.
Geology & Source: Groundwater from the Nassau County Atlantic Coastal Plain aquifer (Magothy and Lloyd aquifers) via the Long Beach Water Department — the Nassau County south shore Long Island barrier island (Cretaceous–Quaternary calcareous-moderate Nassau County Atlantic Coastal Plain aquifer of the Long Island Cretaceous Magothy and Lloyd Formations; south Nassau County barrier island supply); moderately hard supply at 118.5 mg/L in Nassau County.
