Description:
One of Region 4's Regional Applied Research Efforts (RARE) projects resulted in two different studies on cleaning up the Columbia Nitrogen Superfund Site located in Charleston, SC. This site is extensively contaminated with pyrite and elemental sulfur used in phosphate fertilizer production, which resulted in arsenic and heavy metal ground-water contamination. This study examined the effectiveness of using a combination of municipal compost and zero-valent iron PRB to treat arsenic and heavy metals using microbially-mediated sulfate reduction. Preliminary results indicate that PRB is effectively treating ground water with minimal maintenance.
