St Croix County Clean Sweep Hazardous Waste Collections offer residents an opportunity to properly dispose of unwanted and waste chemicals such as pesticides, acids, flammable chemicals, mercury, lead paint, and solvents.

Collections are generally held each Spring and Fall and open to all county residents. Businesses and farmers are encouraged to participate but must pre-register by completing a Business and Farm Pre-Registration Form.

Most items are accepted from residents for free. Motor oil and latex paint are not accepted.
