Description:

There is a critical need to develop and implement effective in-situ treatment methods for organically contaminated groundwater. This SBIR Phase I project focuses on an innovative, in-situ method for remediating organically contaminated soils, sludges, and sediments, by in-situ generation of peroxide, which acts as either an oxidant for destruction of organic contaminants or as an oxygen supply in bioremediation schemes. This method is cost effective and suitable for large-scale field applications. The proposed method: (a) generates the peroxide ions in-situ, in the subsurface layers, thus avoiding the transport of large volumes of oxidant to contaminated sites, (b) transports the peroxide ion in the contaminated groundwater under the application of applied electric fields, for uniform in-situ chemical oxidation, and (c) avoids extensive soil mixing for in-situ application. The use of an electrochemical method allows metering of the peroxide production rate, which prevents overdosing of the system. Additionally, peroxide does not persist in the environment; therefore, there is no possibility of further contamination of the site.
