Bioprecipitation as a Remediation Strategy for Soil and Groundwater Contamination
Bioprecipitation as a Remediation Strategy for Soil and Groundwater Contamination
Bioprecipitation is a soil and groundwater remediation technique. It uses microorganisms as a catalyst to enhance the chemical precipitation process. The method aims to immobilize soluble contaminants as less soluble hydroxide, carbonate, phosphate and/or sulfide precipitates. The process can function with numerous microorganism species. However, it is often applied with sulfate-reducing bacteria, nitrate-reducing bacteria or ureolytic bacteria. These species typically require an electron donor to facilitate the process. Application of bioprecipitation can occur as an ex-situ or in-situ operation, whereby in-situ operations offer a more sustainable approach. In every scenario, a comprehensive site assessment and laboratory testing is required to establish feasible designs.
