98% fermentable blend containing both quick release ethyl lactate and slow-release long-chain oleaginous materials. Designed for sites where a slow-release substrate is needed (i.e. sites with high mobilization/injection costs), DNAPL source treatment, PRBs, cutoff ...
To reduce this remediation timeframe, the Army con-ducted source removal via trench excava-tion in 2000 followed by NAPL removal using ERH and multi phase extraction (MPE) from 2003 to 2007. ...
Executive Summary Dense, nonaqueous-phase liquid (DNAPL) contaminants are a challenge to characterize and remediate at many sites where such contaminants have entered the aquifer due to past use or disposal practices. Chlorinated solvents, comprised of chlorinated volatile organic compounds (CVOCs), such as trichloroethylene (TCE) and perchloroethylene (PCE), are common DNAPL contaminants at ...
Remediation Costs: • Enhanced Bioremediation $29/yd3 • Thermal Treatment $88/yd3 • Chemical Oxidation $125/yd3 • Surfactant Co-solvent Flushing $385/yd3 From: McDade, Travis, and Newell, 2005. Analysis of DNAPL source-depletion costs at 36 field sites. Remediation Journal 15, 9-18. ...
Challenges related to pesticide point-source contamination of groundwater Ida Holm Olesen (Region of Southern Denmark, DK) ? Finding the significant pesticide-point sources – an overview of approaches available Nina Tuxen (Orbicon A/S, DK) ? ...

The remedial action objective was to remove DNAPL to protect the drinking water source beneath the contami-nated area, and reduce the contaminant concentrations in groundwater to levels indicating DNAPL was below concen-trations protective of human health and the environment. ...
- The full-scale operation for groundwater and dense non-aqueous phase liquid (DNAPL) remediation usingFenton’s chemistry-based Oxy-Cat™ began in April 2001. ...
