Those aging cans of bug spray and paint stripper in the garage don't have to be poured down the drain or in the back yard. Instead, Pasco residents can get rid of those commonly found household hazardous wastes safely at the county's quarterly "toxic waste round-up." The roundup is scheduled for 7 a.m. to 3 p.m. Feb. 29 at Land O'Lakes High School on U.S. 41. Residents will be allowed to turn in up to 50 pounds of hazardous waste, including pesticides, solvents, paint strippers, paint thinners and pool chemicals. County officials also plan to accept and recycle batteries and used motor oil. There is no charge for dropping off waste. County officials will not accept medical waste, explosives, wastes containing PCBs, aerosols, cylinders of compressed gases or materials that react violently to water, heat, pressure or sudden movement.
