Development and Field Evaluation of an Abiotic/Biotic Method for the Remediation of Chrome VI

A method has been developed which, for the first time, can be used for the remediation of chrome that combines both abiotic and biotic processes using injected materials. The technology uses an organic compound to reduce chrome VI to chrome III abiotically whereupon the organic by-product is then used as a carbon source for further reduction through biological activity. The process is currently being used at field scale for the remediation of ground water impacted by chrome VI with concentrations as high as 300 mg/L. Evidence suggests that the unspent reductant will move through the aquifer by advection, reducing any chrome VI it may encounter. Long-term experiments indicate that the reduction of chrome VI to chrome III through this technology is permanent.
