WETHERILL ESTATES Water System
Consumer Confidence Report status
WETHERILL ESTATES 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 WETHERILL ESTATES.
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.

WETHERILL ESTATES is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 250 people from groundwater.
As of August 1, 2026, its federal record holds 116 entries between 1998 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 116, 106 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, synthetic organic chemicals, and inorganic chemicals.
