Case Study - Chlorinated solvents bioremediation
BIOREMEDIATION STUDY FOR THE REMOVAL OF CHLORINATED SOLVENTS FROM AN ACQUIFER
- Tetrachloroethilene PCE
- Trichloroethilene TCE,
- cis-1,2 -Dichloroethene
- 1,1 Dichloroethene
- Vinyl chloride
Proposed Remediation Approach
In situ bioremediation (ISB)
Stimulation of natural occurring microorganism to degrade chloroethene contaminant. Biostimulation involves the delivery of an electron donor into the subsurface.
A microcosm test set up at Biosearch Ambiente’s laboratory allowed the determination of the feasibility of a bioremediation approach on a chlorinated solvent impacted groundwater.
Electron donors, as nutrients for the autochthonous microorganism, were added to the contaminated water to stimulate chloroethenes biodegradation.
