Willingboro Water Hardness & Quality Report (2026)

The Willingboro Municipal Utilities Authority (WMUA) supplies potable water and sanitary sewer services to the Township of Willingboro and portions of Westampton in Burlington County, New Jersey. The utility serves approximately 35,424 residents from groundwater sources in the local Coastal Plain aquifer, operating from its facility at 433 John F. Kennedy Way, Willingboro, NJ 08046-2119. Annual Consumer Confidence Reports are available at wmua.info, with the 2025 edition detailing current compliance and quality metrics. The supply relies entirely on groundwater, with no surface reservoirs.

The water originates within the Delaware River watershed's groundwater component, specifically the unconfined and confined aquifers of the New Jersey Coastal Plain. Key geological features include Cretaceous and Tertiary sands and clays overlying limestone and dolomite formations of late Mesozoic age. As groundwater percolates through these fractured carbonate layers and sand aquifers in low-flow subsurface environments, it naturally dissolves calcium and magnesium ions over prolonged contact periods, resulting in a moderately mineralized, hard water character typical of New Jersey's carbonate-influenced coastal plain geology.

Hard water in Willingboro leads to significant scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan. White mineral deposits on fixtures and reduced soap lathering are common signs. Regular vinegar descaling, scale inhibitors, or flushing hot water heaters is advised, and a water softener is strongly recommended to protect household plumbing and appliances from long-term damage. WMUA's reports note potential contaminants including cadmium, PFAS, and mercury; treatment involves standard groundwater processes including chlorination, and the utility meets EPA standards for lead and copper at the tap, with ongoing monitoring per annual CCR reports at wmua.info.
