Description:
The failure of what have been termed convential methods to reclaim contaminated environmental media has over the years lead to the interest and development of alternative technologies. One of these technologies is bioremediation, or the utilization of microbial agents to reduce the overall mass of toxicity of contamination within soil and groundwater systems. Bioremediation has its origins in the SunTech process which was patented in 1974. The process relied on the addition of oxygen and nutrients to contaminated portions of an aquifer to stimulate the reduction of contaminants through microbial processes. The SunTech process used an in-well air sparging apparatus to supply oxygen to the microflora within contaminated systems. For years, variants of this technology have been used in remediation efforts with varing degrees of success. All utilized the more thermodynamically favorable aerobic process.
