Household Chemical Roundups
Household chemical roundup community events help dispose of chemical waste properly, prevent pollution, and protect the people handling your garbage.
Review your county's information below. You can also call the Household Chemical Roundup hotline at 303-846-6249. We coordinate Douglas County events only. Adams County and Arapahoe County events are organized by their individual cities. Contact your city for their next event.
In response to safety precautions involved with the pandemic, our event structure has changed. We are now offering appointment-only Mini Pop-Up Events and Door-to-Door services in Douglas County. We are currently planning the next mini pop-up event with information coming soon.
Door-to-Door Service
Door-to-Door service is available for a limited 20 households per month through June 2021 for a $25 fee. Call 303-269-9448 to schedule your appointment.

Safe Handling of Household Hazardous Items
Many common products found in your home may be hazardous to you, your family, and the environment if used or disposed of improperly. Some of these chemicals include oil-based paint, mercury, gasoline, degreasers, cleaning compounds, and garden chemicals.
Disposing of chemicals properly reduces harm to sanitation workers, sewage treatment plants, and landfills. It also protects our environment by reducing pollution in our water and air.
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. Find safe handling tips by visiting the EPA's Household Hazardous Waste webpage.
