What is hazardous waste?

Hazardous waste is anything that (1) might cause harm or damage if handled incorrectly, such as mercury or certain cleaners; or (2) might leach into the water table if put into our landfills, such as liquid fertilizers, some liquid cleaners, antifreeze, and used oil. Some waste is too dangerous for Benton County's HHW collection events. These include, but are not limited to, ammunition, radioactive materials, and asbestos. Such waste will need specialized handling. You should contact a company who is licensed and trained in their handling.
