Household Chemical Roundups

Workers in Neon Safety Vests Sorting Household Hazardous Waste at an Outdoor Collection Event

COVID-19 Update

All Household Chemical Roundup events have been postponed and we are evaluating the best and safest way to ensure residents have access to responsible disposal options. See "Other Options" tab below for alternative disposal resources.

Household Chemical Roundup Events

We organize Household Chemical Roundups for Douglas County in the spring and summer. Events for Adams and Arapahoe Counties are organized by their individual cities, which should be contacted for further information. These community events help dispose of chemical waste properly, prevent pollution, and protect the people handling your garbage.

Last year, 3,616 households from Adams County and Douglas County participated in the roundups, disposing and recycling 460,153 pounds of household hazardous waste.

Safe Handling of Household Hazardous Items

Many common products found in your home, such as oil-based paint, mercury, gasoline, degreasers, cleaning compounds, and garden chemicals, may be hazardous to you, your family and the environment if used or disposed of improperly. 

It is important to read the product labels to safely store, use, and dispose of chemicals. When these chemicals are not used up entirely, they become household chemical waste and must be disposed of properly or it can harm sanitation workers, create problems in sewage treatment plants and landfills, or pollute the water or air.
