Bushwick Water Hardness & Quality Report (2026)

The New York City Department of Environmental Protection (DEP) provides water to Bushwick, a neighborhood in Brooklyn, Kings County. Water is sourced from 19 reservoirs and three controlled lakes in the Catskill/Delaware and Croton watersheds upstate, delivered via aqueducts to distribution points including the Hillview Reservoir. Treatment occurs at the Croton and Catskill systems, with disinfection via chloramine and UV at select facilities before entering the city's pipe network serving over 8 million residents citywide.

The Catskill/Delaware watershed spans the Catskill Mountains and Delaware River basin, underlain by ancient metamorphic rocks including schist and gneiss from the Precambrian era, with some Paleozoic sandstones. The Croton watershed features similar geology with gneiss, granite, and minor limestone influences. These non-carbonate formations limit mineral dissolution, producing soft water from Catskill/Delaware sources and moderately mineralised water from Croton, resulting in a blended soft overall supply protected by 2,000 square miles of forested land.

Moderately soft water can still lead to some scale buildup on fixtures and reduced efficiency in dishwashers, washing machines, and coffee makers over time. Maintenance includes monthly vinegar soaks for showerheads and faucets, lowering hot water temperature to 60°C to minimize scaling, and periodic descaling of appliances. A water softener is typically not required but may benefit households with heavy appliance use or aesthetic preferences for reduced spotting. NYC DEP water maintains pH around 7–8 with excellent lead and copper compliance under the LCR aided by corrosion inhibitors; PFAS levels are below NYSDOH limits, and treatment includes filtration, UV disinfection, chloramination, and fluoridation.
