WEST MANCHESTER TWP AUTH Water System
Consumer Confidence Report status
WEST MANCHESTER TWP AUTH must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.
As of August 1, 2026, EPA's federal records show no open violations for WEST MANCHESTER TWP AUTH.
Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Pennsylvania’s official records. Always confirm current status with Pennsylvania before making decisions based on this information.

WEST MANCHESTER TWP AUTH is one of 298 community water systems in Pennsylvania in the 3,301 to 10,000 people size category, serving 9,960 people from groundwater.
As of August 1, 2026, its federal record holds 446 entries between 1976 and 2025, all of which EPA lists as closed.
Of the 446, 442 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals, inorganic chemicals, and the Radionuclides and Revised Rad Rule.
