Consumer Confidence Report status
LONDONDERRY COURT MHP 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 LONDONDERRY COURT MHP.
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.

LONDONDERRY COURT MHP is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 160 people from surface water.
As of August 1, 2026, its federal record holds 133 entries between 1982 and 2026, all of which EPA lists as closed.
Of the 133, 114 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 inorganic chemicals, volatile organic chemicals, and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
