Dispose of Household Hazardous Waste Properly

NitrateHousehold hazardous wastes are materials used in the home that can cause injury or are harmful if disposed of improperly. Examples include pesticides, fertilizers, motor oil, antifreeze, adhesives, drain cleaners, bleach, fluorescent bulbs, paint or solvents; never dump these items into a storm drain, open waterway or ditch. Storm drains discharge directly to streams without the benefit of treatment, unlike the drains inside homes and businesses that connect to the sanitary sewer system. Beyond posing a threat to our health and environment, such dumping is illegal. Some common household items contain hazardous materials, such as mercury (in old thermometers), and must be discarded in a responsible manner.

For proper household hazardous waste disposal information, call the Solid Waste Authority of Central Ohio (SWACO) at 871-5100. They offer several mobile droOil, Paints, Etcp off collection events as well as a permanent facility; check for locations, dates/hours, and accepted materials: Dispose of Household Hazardous Waste
