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.

Consumer Confidence Report status

SHAMOKIN DAM BOROUGH 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 SHAMOKIN DAM BOROUGH.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026.

System facts

System ID (PWSID): PA4550022
System type: Community Water System
Population served: 1,700
Service connections: 748
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

SHAMOKIN DAM BOROUGH is one of 757 community water systems in Pennsylvania in the 501 to 3,300 people size category, serving 1,700 people from surface water.

As of August 1, 2026, its federal record holds 166 entries between 1982 and 2025, all of which EPA lists as closed.

Of the 166, 162 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 the Surface Water Treatment Rules.
