YERKES WATER ASSOCIATION Water System

Consumer Confidence Report status

YERKES WATER ASSOCIATION 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 1 item for YERKES WATER ASSOCIATION that is open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

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.

YERKES WATER ASSOCIATION is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 165 people from groundwater.

As of August 1, 2026, its federal record holds 141 entries between 1991 and 2026, of which 1 remains open; none are health-based.

Of the 141, 124 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, the Groundwater Rule, and inorganic chemicals.

What is a Consumer Confidence Report?

A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
