Holiday City-Berkeley Water Hardness & Quality Report (2026)

The Berkeley Township Municipal Utilities Authority supplies drinking water to roughly 10,000 residents in Holiday City-Berkeley, Ocean County, New Jersey. Their water comes from several groundwater wells that tap into the Cohansey-Kirkwood aquifer. This aquifer is primarily located within the Kirkwood Formation, known for its permeable sands. Water is treated at the authority's central plant, where processes like aeration, filtration, chlorination, and corrosion control are employed before the water is distributed to homes and businesses.

The Cohansey-Kirkwood aquifer system is part of the Atlantic Coastal Plain. It's composed of Miocene-age sands and gravels layered over clays. While the sandy composition might suggest softer water, the presence of discontinuous shell beds and limestone lenses within the aquifer dissolves moderate amounts of calcium and magnesium. This geological makeup results in water that is moderately mineralized, unlike the very soft water found in pure sand aquifers or the extremely hard water characteristic of regions dominated by limestone.

Homeowners might notice moderate scale buildup in appliances like water heaters and dishwashers due to this mineral content. You may also find that soap doesn't lather quite as readily, and glassware sometimes shows spots after washing. To manage these effects, regularly descaling fixtures with vinegar and flushing your water heater annually can help. For persistent issues or to extend the lifespan of your appliances, installing a water softener is often recommended. The Berkeley Township Municipal Utilities Authority reported compliance with all federal drinking water standards in its 2024 Consumer Confidence Report.
