Newburgh Water Hardness & Quality Report (2026)

The City of Newburgh Water Department serves approximately 28,000 residents in the City of Newburgh and parts of the Town of Newburgh, Orange County, New York, along the Hudson River. Primary supply is purchased from the New York City Department of Environmental Protection (DEP) via the Delaware Aqueduct, sourcing from the Catskill and Delaware reservoir systems. Supplemental sources may include local Hudson River intakes or wells. Treatment occurs at the Newburgh Water Treatment Plant, with distribution managed by the city utility at 83 Broadway, Newburgh, NY 12550.

The Delaware Aqueduct conveys water from the Catskill-Delaware Watershed spanning Ulster, Greene, Delaware, and Schoharie counties, underlain by Devonian-age Catskill Formation sandstones, shales, and Hamilton Group limestones, with overlying Silurian-Devonian dolomites. Glacial till and outwash from the Wisconsinan glaciation overlay fractured bedrock aquifers. Natural leaching from these carbonate-bearing formations imparts a moderately mineralised character, contrasting with softer profiles from purely siliceous terrains further upstream.

Moderately hard water produces moderate scale buildup in water heaters, dishwashers, and coffee makers, reducing efficiency and increasing energy costs over time. Laundry and dish detergents work less effectively, often requiring higher usage. Regular vinegar descaling, drain screens, and detergent boosters help mitigate these effects. A water softener is recommended for households with hard water concerns to extend appliance life and improve soap lathering. Newburgh's water quality is rated excellent — the 2023 Annual Water Quality Report (CCR) confirms zero violations; treatment includes filtration, chlorination, and corrosion control; pH is typically stable in the 7–8 range per regional DEP data.
