ABSTRACT:
Substrates polluted with toxic substances are treated in-situ with solvated electrons prepared chemically or electrochemically. The process is useful in treating porous and nonporous substrates, such as earth, clay, sand, soils, concrete, asphalt, wood, brick, block and other masonry surfaces, including liquids such dielectric fluids contaminated with halogenated hydrocarbons without the usual separation procedures to provide substrates suitable for recycle having <1 ppm pollutant remaining.
