What Makes Elmont's Water Unique?
Local geology and source profile
Elmont, New York, an unincorporated community in Nassau County — a major northwest Nassau County suburban community (Elmont is directly adjacent to the Queens border in northwest Nassau County — a densely populated inner Nassau suburb, one of the gateway communities from Queens into Nassau County), home of Belmont Park (Belmont Park — the famous horseracing track in Elmont — is one of the oldest and most storied thoroughbred racetracks in the United States, host of the Belmont Stakes, the third leg of the Triple Crown; it is one of the largest horseracing venues in North America), a diverse Nassau County community with a significant Jamaican-American, Haitian-American, and West Indian-American population (Elmont is one of the most Caribbean-American communities in Nassau County), and a community that has undergone significant demographic change since the 1980s — draws its municipal water supply from the Nassau County Magothy Aquifer via the Elmont Water District. Water hardness in Elmont measures 81 mg/L — classified as moderately soft.
Elmont's moderate softness reflects the northwest Nassau County Magothy aquifer supply characteristics. The Magothy Formation at Elmont–Nassau County (Cretaceous calcareous-poor sands and gravels) provides the primary northwest Nassau supply. The Elmont Water District treatment produces the moderate 81 mg/L.
With hardness at 81 mg/L, Elmont residents enjoy moderately soft water. Elmont Water District 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 Formation) via the Elmont Water District — the Nassau County northwest Long Island suburban Elmont corridor (Cretaceous calcareous-poor Nassau County Atlantic Coastal Plain Magothy aquifer of the Long Island aquifer system; northwest Nassau County supply from the calcareous-poor Magothy and Jamaica aquifer zone); moderately soft supply at 81 mg/L in Nassau County.
