- Effective bioremediation achieved in low permeability soils at a retail dry cleaner in the Greater Toronto Area (GTA).
- cDCE stall corrected within 8 months of bioaugmentation, with no vinyl chloride accumulation.
- Ontario regulatory standards (Table 3) were achieved for all chlorinated volatile organic compounds (cVOCs) approximately 1.5 years after KB-1® bioaugmentation.
- Bioremediation following steam injection decreased TCE concentrations to less than 2 µg/L in all source area wells
- Biobarrier successful in preventing TCE mass from migrating off-site
- Site Closure achieved
- Effective bioremediation remedy implemented in a low permeability unit
- TCE MCLs reached in half the expected time-frame
- Remedy-In-Place designation by Wyoming DEQ and EPA within 2 years
- Project won Assoc. of Consulting and Engineering Companies, Engineering Excellence Award for Colorado with submission "Empowering Nature, Delivering Results"
- The study results were used by the client to select the most appropriate remedy for field implementation
- Study demonstrated that KB-1® Plus bioaugmentation promoted 1,1,1-TCA dechlorination and TCE dechlorination to ethene
- Study demonstrated that alkaline-activated persulfate promoted the complete destruction of TCE and partial destruction of 1,1,1-TCA
- Implementation of a 1,250 foot wide KB-1® bioaugmented barrier
- Treatment of VOCs under high groundwater velocity conditions
- Conversion of high TCE concentrations to non-toxic ethene
