History, Phosphate fertilizers were in use as early as the late 1700's in South Carolina, as deposits of mineable phosphate ore were discovered in many areas in the Low Country. During the mid-1800's, it was discovered that mixing the raw phosphate ore with sulfuric acid produced a "super-phosphate" fertilizer that was water soluble for better absorption by crops. Also, it could be produced in a fine, dry…, Research, In the mid-1990's, DHEC Site Assessment staff began working with USEPA to identify all super-phosphate sites within SC. The initial focus was on the Charleston neck area, which was home to many of the largest super-phosphate producers. However, plants were discovered across the state. A key historical resource is the existence of Sanborn insurance maps. These maps were originally produced for the…, Assessment, DHEC has identified 38 former super phosphate sites to date. Thirty of these sites included sulfuric acid production on-site. Five sites purchased their sulfuric acid and did not make their own. The remaining three sites have no evidence of acid production or use. All of these former sites have received at least initial screening assessments. Thirteen sites have received cleanups under EPA…
