// Strategic Significance

The Velsicol Chemical site in Hardeman County Tennessee stored pesticide production wastes including heptachlor and chlordane contaminating groundwater for miles. Over 100 families had their wells contaminated. The site was one of the first to trigger federal Superfund action and helped lead to the creation of the Superfund law.

// Civilian Impact Assessment

Hardeman County residents experienced contaminated private wells with chlordane and heptachlor for years before cleanup. The site is in a rural agricultural area where private well use is common.

// Evacuation & Shelter Guidance

Hardeman County residents with private wells near the site should test for chlorinated pesticides. Tennessee DEP monitors groundwater recovery.
