A process for disposing of solvent-containing liquids so that they do not contaminate ground water. The process includes the steps of transferring the waste solvent-containing liquid to a container and adding sufficient water so that the solvent-containing liquid has about 50% water content. Next, an absorbent blend is mixed into the liquid at the rate of about 1 lb. of blend per gallon of liquid. The blend is made up of a swellable polymer, consisting of polyacrylamide/polyacrylate copolymer salt or poly 2-propenamide-co-2-propenoic acid homopolymer salt which swells and absorbs liquid. The blend also contains a mixture of solid absorbents selected from calcium oxides, aluminum oxides, calcium sulfate, silicon oxides, pumice, perlite, activated carbon, surfactant, and ground corn cobs. The resulting mixture is stirred in the container until it becomes thick and then it is allowed to set to provide a disposable modeling clay-like solid. The resulting solid material, after curing, may be then simply added to solid trash, and thus, be freed from contaminating ground water. The process is especially useful for disposing of most all cleaning solutions.
