Household Chemical Roundup Events

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. Below, you will find current information for events and disposal services. You can also call the Household Chemical Roundup hotline at 303-846-6249 for updates on events by county.

Last year, 3,296 households from Douglas County participated in the roundups, disposing and recycling 475,640 pounds of household hazardous waste. Check out our Storyboard detailing the accomplishments made during our 2019 Castle Rock event.

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.
