The City of Burlington Wastewater Treatment Facility is a mercury collection site. Mercury light bulbs and thermometers that are not properly disposed of can cause potentially harmful mercury poisoning. Please keep the City's Wastewater Treatment Facility in mind when you have mercury-containing items to dispose of. Bring your old mercury thermometers and light bulbs to 2100 South Pine Street. Used household batteries are also accepted (vehicle batteries are excluded). Items can be dropped off Monday through Friday between the hours of 7 a.m. and 2 p.m. There is no charge for this service; however, it is limited to City of Burlington residents. Proof of residency will be required. Please feel free to call 262-539-3646 with any questions.
