This drinking water quality report shows results of tests conducted by water utilities in Mississippi, provided to the Environmental Working Group (EWG) by the State water agency. It is part of EWG's national database that includes 47,667 drinking water utilities and 20 million test results from 45 states and the District of Columbia. Water utilities nationwide detected more than 300 pollutants between 2004 and 2009. More than half of these chemicals are unregulated, legal in any amount. Despite this widespread contamination, the federal government invests few resources in protecting rivers, reservoirs, and groundwater from pollution in the first place. The information below summarizes drinking water quality for this state.

The state water agency did not respond to requests for water quality test data. Contact your water utility for the latest water quality report
