Little Ferry Water Hardness & Quality Report (2026)

The Little Ferry water utility, serving about 20,000 residents, draws its supply from a combination of sources. The primary source is the Hackensack River, managed by the Hackensack Water Supply Company (now part of United Water New Jersey). This surface water is supplemented by groundwater from local aquifers. Treatment is not localized to Little Ferry itself but occurs at regional facilities, such as the Little Falls Treatment Plant, with water then distributed through the borough's municipal pipes.

The geology beneath Little Ferry contributes significantly to its water quality. The area sits within the Northern Atlantic Coastal Plain, characterized by unconsolidated sediments from Pleistocene glacial deposits. These lie atop Cretaceous sands and clays belonging to the Raritan and Magothy Formations. While limestone is not present, the glacial till and carbonate-bearing sands in the region leach dissolved calcium and magnesium ions into the water. Runoff from the Watchung Mountains, influenced by Triassic sandstone and basalt, further adds to the water's mineral content.

Homeowners in Little Ferry will likely notice the effects of hard water on their appliances and plumbing. Scale buildup is common in pipes, water heaters, and dishwashers, which can reduce their efficiency and shorten their lifespan. You might also find white mineral deposits on faucets and sinks, and notice that soap doesn't lather as easily, requiring more detergent for cleaning. Regularly descaling fixtures and appliances with vinegar can help manage this. For persistent issues, installing a water softener is a practical solution to protect your household items and improve cleaning performance.
