Abstract
A method of in-situ bioremediation for treating underground nonaqueous phase liquid contamination. This includes providing a delivery means for supply acetic acid to a DNAPL target zone. The next step includes supplying the acetic acid by the delivery means so that the acetic acid is introduced into the DNAPL target zone. This allows the natural microorganisms in the DNAPL target zone to metabolize the acetic acid thereby creating anaerobic conditions and destroying DNAPL chemicals. The final step includes maintaining the anaerobic conditions for a sufficient period of time such that the microorganisms are enhanced and produced until remediation is complete.
Claims16
A method of in-situ microorganism generation for treatment of underground DNAPL contamination comprising the steps of:
- a) providing a delivery means for supplying acetic acid to a DNAPL target zone;
- b) supplying said acetic acid by said delivery means whereby said acetic acid is introduced into said DNAPL target zone whereby the natural microorganisms in said DNAPL target zone metabolize said acetic acid thereby creating anaerobic conditions and reducing DNAPL chemicals;
- and
- c) maintaining said anaerobic conditions for a sufficient period of time such that the number of said natural microorganisms are enhanced and increased.
