PFAS Contamination in Mississippi

Mississippi faces PFAS contamination primarily from military installations and industrial facilities across the state's diverse geological regions. Keesler Air Force Base in Biloxi has documented significant soil and groundwater contamination from firefighting foam use, with potential migration toward Mississippi Sound and the Gulf Coast aquifer system. Columbus Air Force Base has additional contamination affecting the Tombigbee River watershed and surrounding agricultural areas.

The state's industrial corridor along the Mississippi River has potential PFAS sources from chemical and petrochemical facilities. Mississippi's agricultural economy faces particular risks from contaminated groundwater affecting livestock operations and irrigation systems. The state's complex geology, including the Mississippi River alluvial aquifer and coastal plain aquifers, creates unique contamination transport and remediation challenges.
