The Household Chemical Roundup is a one-day household hazardous waste collection event for City of Aurora residents. Help staff collection stations, register volunteers, direct traffic or unload vehicles at this important pollution prevention event. Volunteers are needed for two shifts - 8 AM to 1 PM and 11:15 AM to 4:15 PM. Volunteers receive a free gift, great lunch and do not need to wait in line to drop off chemicals. Although the event is limited to city of Aurora residents only, volunteers living outside of the city may drop off acceptable products. We would love to see you there.
