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): MS0410013
System type: Community Water System
Population served: 1,500
Service connections: 751

Water source: groundwater (wells)

TOWN OF SHANNON is one of 794 community water systems in Mississippi in the 501 to 3,300 people size category, serving 1,500 people from groundwater.

As of August 1, 2026, its federal record holds 90 entries between 2005 and 2024, all of which EPA lists as closed.
