Levittown Water Hardness & Quality Report (2026)

Levittown, Pennsylvania, in Bucks County on the Delaware River — the iconic post-World War II planned suburb built by William Levitt in 1952, one of the first and largest mass-produced suburban communities in the United States, now a diverse Bucks County community — draws its municipal water supply from the Delaware River and Neshaminy Creek via the Pennsylvania American Water Company (PAWC) Suburban Division and the Bucks County Water and Sewer Authority. Water hardness in Levittown measures 175 mg/L — classified as hard.

Levittown's hard supply reflects the Bucks County Delaware River watershed's calcareous geology. The Delaware River above Levittown–Bristol drains: the New Jersey–Pennsylvania Triassic–Jurassic Newark Basin (Triassic Stockton Formation calcareous red bed arkose and Lockatong Formation calcareous argillite — contributing dissolved calcium from the calcareous Triassic basin formations); the Pennsylvania Piedmont crystalline belt; and the Devonian calcareous marine formations of the upper Delaware Valley. Levittown's distribution infrastructure — built during Levitt's 1952–1958 construction using cast-iron mains in the classic Levittown radiating-street layout — is now 65+ years old and accumulates significant mineral content, producing the hard 175 mg/L.

At 175 mg/L, Levittown residents face regular hard water challenges. Scale deposits form on faucet aerators, showerheads, and appliances within weeks — monthly descaling with citric acid solution is standard maintenance. Pennsylvania American Water Company consistently delivers water meeting all Pennsylvania DEP and EPA Safe Drinking Water Act requirements.
