1,1,1-TCA Bioremediation at an Industrial Site in Dayton, Ohio
CL-Out bioremediation reduced the concentration of 1,1,1-TCA in ground water at a steel manufacturing facility in Dayton, Ohio. Following implementation of ozone treatment and high vacuum extraction for more than 2 years, the contaminant concentrations remained high. Bioaugmentation followed up on these treatments and reduced the 1,1,1-TCA concentration very quickly. Within 30 days of bioaugmentation, the source area contaminant concentration decreased by 80%. After a second application, the concentration decreased from the pre-treatment concentration of 1,100 ug/L to 1.4 ug/L. The bioaugmentation effect was observed as far as 250 feet downgradient where the concentrations decreased by more than 50%. Click here for the full case study.
