A REVIEW OF THE U.S. ENVIRONMENTAL PROTECTION AGENCY'S RESEARCH PROGRAM ON THE PREVENTION AND CONTROL OF HAZARDOUS MATERIAL SPILLS

Under contract to the U.S. Environmental Protection Agency, Calspan Corporation developed methods to treat, control and monitor spilled hazardous materials. One of the most successful spill countermeasures applied was a dry, finely-granulated blend which would, within seconds after contact with spilled liquids, begin their transformation into tough, immobile gels which could be easily controlled and removed. This blend is a "universal gelling agent" in the sense that it can immobilize essentially all hazardous liquid spills within foreknowledge of the liquid composition. The blend contains powdered polymeric components optimized separately for interaction with aqueous liquids, chlorinated organics, alcohols, and nonpolar hydrocarbons. It also contains a fumed silica fluidizer, which provides ease of field application and imparts longer term stiffening of all gels formed. The "universal gelling agent" has been demonstrated to be effective on a variety of medium scale (55-gallon drum) spills on both land and water. For special uses, such as organophosphrous pesticide spill control, the blend can be reformulated to include de-toxifying (oxidizing, hydrolytic) ingredients as well.
