DUNCANNON MUNI WATER Water System
Consumer Confidence Report status
DUNCANNON MUNI WATER 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 DUNCANNON MUNI WATER.
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.

DUNCANNON MUNI WATER is one of 757 community water systems in Pennsylvania in the 501 to 3,300 people size category, serving 2,000 people from groundwater.
As of August 1, 2026, its federal record holds 290 entries between 1984 and 2025, all of which EPA lists as closed.
Of the 290, 278 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 synthetic organic chemicals, volatile organic chemicals, 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.
