Willingboro Water Hardness & Quality Report (2026)

Willingboro, New Jersey, in Burlington County — a major south New Jersey suburban community (Willingboro is a historically significant Burlington County township — it was one of the first major planned communities in the United States built by William Levitt (of Levittown fame), marketed as 'Levittown, New Jersey' when it opened in 1958; Willingboro became a model for racial integration in American suburban communities, one of the first American suburbs to achieve racial diversity in the 1960s–1970s), a diverse Burlington County community with a significant African-American majority population and working-class to middle-class suburban heritage, adjacent to Rancocas Creek and the NJ Turnpike corridor, home of the Willingboro Town Center (a significant community retail center), and a community that has been subject to numerous sociological studies on American suburbanization and racial integration — draws its municipal water supply from the Potomac–Raritan–Magothy aquifer via the Willingboro MUA. Water hardness in Willingboro measures 73 mg/L — classified as moderately soft.

Willingboro's moderate softness reflects the south New Jersey coastal plain aquifer's calcareous-poor Cretaceous geology. The Potomac–Raritan–Magothy aquifer draws from the Cretaceous Raritan and Potomac Formations (calcareous-poor coastal plain sand and gravel). Willingboro MUA produces the moderately soft 73 mg/L.

With hardness at 73 mg/L, Willingboro residents enjoy moderately soft water. Willingboro MUA consistently delivers water meeting all New Jersey DEP and EPA Safe Drinking Water Act requirements.
