TerraStryke Erdenhanced Residual DNAPL Source Zone Remediation Simple Additive Delivery Approach; Future Retail Development, Ottawa QC - Case Study
TerraStryke Products LLC develop and distribute biostimulation additives proven to cost-effectively maximize the performance of your bioremediation project; expediting contaminant destruction, eliminating rebound, to realize long-term compliance with minimal impact and less cost. ERDenhanced is our patented biostimulation additive that provides a carbon-nutrient based formulation that stimulates biofilm development to realize sustainable and complete biotransformation of site cVOC contaminants.
Site: Future retail development site contaminated with Trichloroethylene (TCE) in groundwater at dissolved-phase concentrations indicative of residual DNAPL.
Process: 9-month evaluation with six monitoring wells amended using additive filled Passive Release Sock (PRS) deployment units; three with ERDenhanced and three with a industry standard carbon-based sole electron donor. One well monitored as Control. PRS units are suspended in the saturated casing volume of the test well. Units are replaced periodically (6-8 weeks) to maintain additive residency time. Groundwater monitoring/sampling was performed with each replacement event.
