FULL-SCALE ISCR AND EISB TO TREAT CHLORINATED SOLVENTS IN UNSATURATED SOILS AT A FORMER CHLORINATED SOLVENTS MANUFACTURING PLANT
Daniels, J. and M. Motylewski.
Eleventh International Conference on Remediation of Chlorinated and Recalcitrant Compounds, 8-12 April, 2018. Battelle Press, 14 slides, 2018
The Ethyl Corporation operated a former chlorinated solvent manufacturing plant in Baton Rouge, Louisiana. Shallow soils were affected to ~15 feet bgs by carbon tetrachloride, 1,2-DCE, 1,1,2-TCA, TCE, and PCE, with concentrations >100 ppm in multiple locations. Review of historical data identified in situ chemical reduction and enhanced in situ bioremediation as appropriate technologies to meet project goals. After a successful feasibility test, full-scale remediation took place December 2016-February 2017. Results showed chlorinated VOC concentration reductions at several locations, stability of overall microbial population, an increase in anaerobic and fermenting microbes, and conditions still favorable for continued biodegradation. https://www.gesonline.com/sites/default/files/2018-05/Daniels_FullScaleISCR-EISB_Battelle2018.pdf
