ABSTRACT:
A method and apparatus for the in-situ bio-remediation of contaminated soil and groundwater. Perforated piping embedded within the contaminated region delivers a treatment fluid. The treatment fluid is either a mixture of water, contaminant-eating bacteria and nutrients or a chemical mixture of hydrogen peroxide, a catalyst and water. Ultrasonic or vibratory energy is supplied to the contaminated soil to momentarily increase the permeability thereof. The treatment fluid is then able to flow through the contaminated soil to mix with the contaminants. In one embodiment, an ultrasonic horn located within the perforated piping delivering the treatment solution is used to produce the ultrasonic energy. The ultrasonic horn emits ultrasonic sound waves having a frequency in the range of between 2,000 to 20,000 Hz. In other embodiments, the vibratory energy is emitted by a vibrating plate disposed on a surface of the soil or by a single or plurality of probes embedded within the soil.
