Ridgefield Park Water Hardness & Quality Report (2026)

The Ridgefield Park Water Department supplies the village of Ridgefield Park, New Jersey, drawing its water mainly from the Hackensack River and also utilizing groundwater wells. This mixed supply is treated at the village's own water plant before being distributed to about 13,000 residents. The Hackensack River watershed itself is quite extensive, covering 500 square miles and originating in the Watchung Mountains. The Ridgefield Park Water Department is diligent in its compliance with regulations from both the NJDEP and the EPA, providing annual Consumer Confidence Reports to its customers.

The region's geology is a significant factor in the water's character. It sits atop Triassic-Jurassic red bed formations from the Newark Supergroup, which include mudstones and basalts, as well as more recent Quaternary glacial deposits. This geological setting, combined with the river's flow through mineralized soils and fractured bedrock, particularly limestone and dolomite layers within the Lockatong and Brunswick formations, leads to a naturally hard water supply. Dissolution of calcium and magnesium from these rocks during the water's journey through the Passaic and Hackensack aquifers is the primary reason for its mineral content.

This very hard water can lead to noticeable scale buildup on pipes, water heaters, and fixtures, which can decrease their efficiency and shorten their lifespan. Appliances that use hot water, such as dishwashers and boilers, are particularly susceptible to damage from these mineral deposits. Homeowners might also notice issues like glassware appearing spotty after washing or a feeling of dry skin. To combat these effects, regular descaling with vinegar or installing a water softener are effective measures. They help prevent staining, improve how well soaps lather, and protect your plumbing and appliances. It's also worth noting that while the water meets EPA standards overall, there have been recent monitoring concerns, and certified filters are recommended for reducing certain contaminants like PFAS.
