Cleanups of four Superfund hazardous waste sites are described, two in Pennsylvania, one in Tacoma, Wash., and one in Globe, Arizona. The key chemical wastes were polychlorinated bipheynls, asphaltic sludge, chlorinated organic solvents, and asbestos polluted soil. The key treatment technology in each case, respectively, was incineration at an approved hazardous waste incinerator, in place chemical stabilization, and removal of contaminants from groundwater by air stripping towers. It is concluded that most or all hazardous wastes can be rendered innocuous, but correctives often are costly. Perhaps the primary need today is for more approved hazardous waste incinerator operations, and for more approved hazardous waste landfills.
