There is no cost for Monroe County residents to dispose of the materials at the event. Household hazardous waste are products often found in the garage, sheds, storage areas, or under the kitchen sink. They are corrosive, flammable, reactive, or toxic. E-waste can be items like televisions, computers and laptops, and old cell phones.

"These chemicals can contaminate Monroe County's sensitive ecosystem," said Monroe County Solid Waste Director Cheryl Sullivan. "It is incredibly important to dispose of these chemicals appropriately."
