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.

System facts

System ID (PWSID): VA6099590
System type: Community Water System
Population served: 51
Service connections: 17
Ownership: privately owned
Water source: groundwater (wells)

WALNUT GROVE MHP is one of 2,163 community water systems in Virginia in the 500 or fewer people size category, serving 51 people from groundwater.

As of August 1, 2026, its federal record holds 103 entries between 1985 and 2026, all of which EPA lists as closed.

Of the 103, 74 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 the Total Coliform Rules, the Consumer Confidence 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.

EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
