DPT JET INJECTION FOR REMEDIATION IN CLAY TILL: FULL-SCALE CASE STUDY RESULTS FROM OVER 3 YEARS OF TREATMENT
Ross, C. and D. Eberle.
RemTech 2018, 10-12 October, Banff, Alberta, Canada. 57 slides, 2018
A former industrial facility in Niva, Denmark, was affected by chlorinated VOCs in clay till over ~750 m2 and 6-12 meters bgs. TCE soil concentrations were as high as 83 mg/kg. Following the demonstration of controlled emplacement of 49 tonnes of zero-valent iron into the target treatment zone for chemical reduction of TCE in November 2014, a 5-yr performance monitoring program was initiated to evaluate treatment over time. After 30 months, the estimated mass of TCE decreased by ~92% and the total CVOC mass decreased by 82%. Groundwater data 36 months post-injection indicate that the total CVOC mass discharge from the treatment zone declined by >89%.
