What Makes Throgs Neck's Water Unique?
Local geology and source profile
Throgs Neck, Bronx, New York — a major northeast Bronx peninsula neighborhood (Throgs Neck is a residential peninsula in the northeast Bronx at the junction of the East River and Long Island Sound — one of the most waterfront-oriented neighborhoods in the Bronx, with significant maritime and waterfront character), home of the Throgs Neck Bridge (one of the major bridges connecting the Bronx to Queens over the East River–Long Island Sound strait — a critical part of the NYC tri-state interstate highway system), a diverse Bronx County community with a significant Italian-American, Albanian-American, and Irish-American population, and adjacent to SUNY Maritime College at Fort Schuyler (one of the premier maritime academies in the United States, located at the tip of the Throgs Neck peninsula) — draws its municipal water supply via the NYC DEP. Water hardness in Throgs Neck measures 135.5 mg/L — classified as moderately hard.
Throgs Neck's moderate hardness reflects variation in the NYC Bronx distribution system (notably different from the south Brooklyn or Queens zones). The NYC Catskill–Delaware supply is distributed through the northeast Bronx Throgs Neck zone via older northeast Bronx mains (primarily 1930s–1950s residential peninsula development), producing the moderate 135.5 mg/L.
At 135.5 mg/L, Throgs Neck residents encounter moderate scale accumulation. Monthly cleaning with citric acid solution is recommended. NYC DEP consistently delivers water meeting all New York State DEC and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Catskill–Delaware watershed (Catskill Mountains) via the New York City Department of Environmental Protection (DEP) — the Bronx County northeast Bronx Throgs Neck peninsula (Catskill Mountains calcareous-poor Devonian sandstone and shale — the NYC Catskill–Delaware supply; Throgs Neck northeast Bronx distribution zone); moderately hard supply at 135.5 mg/L in Bronx County.
