  • Bioremediation
Bioremediation is the natural biodegradation of contaminants by micro organisms.  This degradation can be optimized through practices including cultivation and addition of nutrients.

  • Ground Water Pumping and Treatment
Ground Water Pumping and Treatment extracts contaminated ground water and separates the contamination from the water, then destroys the contaminants.  Techniques used to treat ground water include carbon adsorption, air stripping, or biological treatment.
