Redox Flushes Out Contaminants.

A technique developed at the DOE's Pacific Northwest National Laboratory (PO Box 999, Richland, WA 99352; Tel: 509/375-3837, Fax: 509/375-6550) may be able to remove deadly contaminants from groundwater more easily and less expensively than before. Pacific Northwest scientists created "In-Situ Redox Manipulation, " or ISRM, to remediate contaminated groundwater at up to 60% savings over 10 years when compared to current remediation methods. Potential application sites include military bases, petroleum and chemical plants, and weapon production facilities.

ISRM could address the growing concern surrounding chromate--a contaminant found near metal-plating production …
