Mount Laurel Water Hardness & Quality Report (2026)

MT Laurel Township MUA (856-722-5900, 1201 South Church St, Mt Laurel Twp, NJ 08054) provides drinking water to 41,743 residents across Mount Laurel Township in Burlington County, New Jersey. The utility purchases surface water from regional suppliers in the Delaware River watershed and employs conventional treatment including chlorine, hypochlorite, and ozone disinfection. No specific treatment plant names are identified in available reports, but the system relies on purchased surface water as the primary source, with potential groundwater blending from local aquifer sources.

The supply originates in the Delaware River watershed, where surface water reflects contributions from upstream Piedmont rock formations. Locally, groundwater interacts with Coastal Plain geology, including the unconsolidated sands and clays of the Raritan, Magothy, and Cohansey Formations from the Cretaceous and Tertiary periods. These sediments, laced with calcareous materials, impart a moderately mineralised character through natural leaching of alkaline earth metals, resulting in a hard supply prone to scale without altering beneficial mineral content.

At this moderately hard level, scale buildup affects water heaters, dishwashers, washing machines, and faucet aerators most severely, causing reduced efficiency and damage over time. Soap lathering diminishes, leading to drier skin and laundry residue. Regular maintenance includes descaling appliances, installing drain screens, and testing home plumbing for corrosion. A water softener is recommended to mitigate these effects and extend appliance life, though the utility does not soften at source to preserve health-beneficial calcium and magnesium. The system reports multiple contaminants above EPA health-based guidelines; filters are recommended and treatment involves conventional filtration with multi-disinfectant use including ozone.
