Abstract:

Everyone wants the nation's hazardous waste sites cleaned up, but nobody wants the wastes disposed of near them. Therefore, cleaning up these problems at the site may be the best way to conduct clean-ups. There are two general techniques for in-situ clean-ups. Biological methods use microorganisms native to the site to break the hazardous materials down. Man can accelerate the process by altering the site to make conditions more favorable for the organisms. A number of chemical methods are being developed which can flush toxins from the ground or water, immobilize them, or render them harmless.
