Household chemicals should be used in the manner for which they were intended, so try giving leftovers to a friend or neighbor if you can't use them. Never discard chemicals on the ground!
Most residential-type hazardous chemicals, like cleansers, pesticides, herbicides, fertilizers, automotive products, and mercury found in thermostats and thermometers are accepted at the Haz Chem Center, a collection center for the processing and disposal of household hazardous waste, is located near the Des Moines County Regional Landfill and available to the public.
The Haz Chem Center also manages a Swap Shop where you may be able to obtain products at no charge.
For your safety, an appointment is always necessary at the HazChem Center, so please call first. The telephone number is 319-753-8758.
