West New York Water Hardness & Quality Report (2026)

West New York, New Jersey is served by United Water New Jersey (now part of Veolia North America), supplying Hudson County communities including West New York, Guttenberg, and Weehawken. The primary sources are surface water from the Hackensack River and two major reservoirs — the Woodcliff and DeForest Lake systems within the Hackensack River Watershed. Water is treated at the Little Falls Treatment Plant and the Hackensack Water Treatment Plant, collectively serving over 900,000 people across multiple municipalities through a mixed supply integrating river intakes with reservoir storage.

The Hackensack River Watershed spans 250 square miles in Bergen and Passaic Counties, draining into Newark Bay. Underlying geology consists of Mesozoic Triassic Lockatong and Passaic Formations — red beds of sandstone, siltstone, and shale — overlain by glacial till and outwash deposits, forming part of the Newark Supergroup. Karst-influenced tributaries and limestone-bearing soils leach alkaline earth metals into the watershed, imparting a hard character to the supply through dissolution of calcium and magnesium from these mineral-rich sedimentary formations.

Hard water promotes scale buildup in pipes, water heaters, dishwashers, and washing machines — hot water appliances suffer most, with up to 50% higher energy use from limescale insulation. Soap lathering diminishes, leaving spots on dishes and dry skin or hair. Regular vinegar descaling and annual professional flushing help maintain efficiency; a water softener is recommended for households to extend appliance life. Recent Consumer Confidence Reports show compliance with pH 6.5–8.5, lead and copper below EPA action levels via corrosion control, and treatment involving coagulation, sedimentation, filtration, chloramination, and UV disinfection. PFAS monitoring is ongoing per NJDEP standards, with activated carbon filtration addressing organics.
