Whitestone Water Hardness & Quality Report (2026)

Whitestone, New York, a neighborhood in the northeastern portion of Queens, New York City — a primarily residential north Queens neighborhood adjacent to the Bronx–Whitestone Bridge (one of the major bridges connecting Queens and the Bronx across the East River), a diverse Queens neighborhood with a significant Italian-American, Greek-American, and Korean-American population (Whitestone has historically had one of the highest concentrations of Italian-Americans in Queens), near Flushing Bay and the Throgs Neck Bridge, and a predominantly owner-occupied, stable residential north Queens neighborhood — draws its municipal water supply via the NYC DEP. Water hardness in Whitestone measures 174.5 mg/L — classified as hard.

Whitestone's hard supply reflects the NYC DEP Catskill–Delaware distribution in north Queens and the older Whitestone–Flushing area infrastructure. The Catskill–Delaware source (approximately 40–60 mg/L) gains substantial hardness through the older north Queens distribution mains (early 20th century to mid-century Queens borough distribution infrastructure in the Flushing–Whitestone corridor). The north Queens distribution characteristics produce the hard 174.5 mg/L — harder than many other NYC neighborhoods.

At 174.5 mg/L, Whitestone residents encounter regular hard water scale. Monthly descaling with citric acid solution is recommended. NYC DEP consistently delivers water meeting all New York State DEC and EPA Safe Drinking Water Act requirements.
