Port Richmond Water Hardness & Quality Report (2026)

Port Richmond, located on Staten Island's North Shore, receives its water from the New York City Department of Environmental Protection (DEP). This vast system serves over 8 million people across the five boroughs and Westchester. The water originates from 19 reservoirs and three controlled lakes, with the Catskill/Delaware systems providing about 90% of the supply and the Croton system contributing the remaining 10%. This water travels through more than 100 miles of aqueducts to treatment facilities before reaching distribution networks. Staten Island specifically gets a blend of this upstate water, as there are no local treatment plants dedicated solely to Port Richmond.

The Catskill/Delaware watersheds, covering over 1,600 square miles in the Catskill Mountains, are primarily underlain by Devonian-age shales and sandstones, with some minor limestone deposits. These geological formations allow for the dissolution of moderate amounts of calcium and magnesium into the water runoff. The Croton watershed shares similar Paleozoic metamorphic rocks and sediments. This bedrock geology results in water with a moderate mineral content, distinguishing it from the very soft water often found in areas dominated by granitic rock or the extremely hard water characteristic of limestone karst regions.

Homeowners in Port Richmond might notice some scale buildup in appliances like kettles, dishwashers, and water heaters, which can reduce their efficiency and lead to increased energy consumption over time. Showers might feel a bit less foamy, potentially requiring more soap to achieve a good lather, and fabrics can feel stiffer after laundry. To combat scale, cleaning fixtures monthly with vinegar can be helpful, and scale inhibitors can be installed if needed. While a whole-house water softener is optional, it's often recommended for those who prefer softer water or experience frequent scaling issues. The DEP actively manages the system to meet safety standards, including corrosion control to protect older plumbing from leaching, and regularly monitors for contaminants like disinfection byproducts and PFAS, which are typically compliant with EPA regulations.
