Lawrence/Douglas County Household Hazardous Waste Program will accept materials from Douglas County residents during a "dioxin sweep."

From Monday to Oct. 16, farmers, ranchers and even residential households are eligible to participate in a free dioxin disposal program. The program is sponsored by the Kansas Department of Health and Environment, Safety-Kleen Corp., the Kansas Farm Bureau and the Lawrence/Douglas County Household Hazardous Waste Program.

What are dioxins?

Dioxins originally were discovered as a by-product in the trichlorophenol manufacturing process, which has been used to make some pesticides. Dioxins are of concern in the environment because of their ability to accumulate in the body fat of animal tissue. Once in the environment, dioxins do not break down easily. Several of the dioxin molecules are known human carcinogens.

Where are dioxins found?

Dioxins can be found in some very old herbicides and livestock treatment products manufactured prior to the mid-1980s. The most common of these products will contain Silvex, 2,4,5-T and pentachlorophenol. Please check your old pesticides carefully. If they contain these products you need to take advantage of the free disposal program. Here are some old herbicides that may contain dioxins (and their manufacturers) common to Kansas.

What can I do?

Bring your old dioxin-containing pesticides to one of the next three household hazardous waste collection events -- next Saturday, Sept. 18 or Oct. 16 at 711 E. 23rd -- or call 832-3030 to arrange a convenient drop off time. All pesticides must be in their original labeled container and the container should not be leaking.
