Enhancing Reductive Dechlorination

Enhanced reductive dechlorination (ERD) and in-situ chemical reduction (ISCR) are emerging as cost-effective remedial approaches for groundwater with elevated concentrations of chlorinated solvents. ERD involves the addition of an electron donor containing biodegradable carbon to groundwater, which promotes the activity of bacteria and mediates reductive dechlorination reactions. Remediation professionals focused on in situ treatment of groundwater containing chlorinated solvents are increasingly employing systems based on ERD and ISCR. The probability of successful outcomes in their work increases when they use an organic electron donor that is easy to apply, long-lasting, well-distributed, and cost effective. emulsified lecithin substrate and EHC Liquid are new lecithin-based reagents that have these attributes and, therefore, provide an advantageous alternative to other electron donors.
