What is Bioremediation?
Definitions
Biostimulation: The addition of nutritional amendments to increase microbial metabolism and to encourage biodegradation-often organic compounds e.g., EOS®
Bioaugmentation: The addition of beneficial microorganisms to improve the rate or extent of biodegradation
How Does Enhanced Reductive Dechlorination (ERD) Work?
"To clean up leaks from buried gas tanks, for example, it's common practice to pump oxygen into an aquifer for aerobic microbes to break down petroleum. Chlorinated solvents like metal degreasers and dry-cleaning fluid pose a different challenge. Because anaerobic microbes can break off chlorine atoms from the compounds to "breathe," researchers simply inject food into the groundwater for the organisms to feast on as they break down the solvents."
