Household hazardous wastes (HHW) are the leftover or unused portions of materials used to clean and maintain your home. These materials are often labeled CAUTION, WARNING, DANGER, POISON, TOXIC, FLAMMABLE, or CORROSIVE. For safety and environmental reasons it is illegal to dispose of HHW in the garbage, sewers, or storm drains. Please take these materials to a Household Hazardous Waste Collection Facility. The facility is available to the residents of the following East Contra Costa County communities: Antioch, Bay Point, Bethel Island, Brentwood, Byron, Discovery Bay, Knightsen, Oakley and Pittsburg. You will need to show proof of residency – such as a utility bill or driver’s license. Also accepts electronic waste (e-waste). See website for acceptable and unacceptable materials, and packing and transportation guidelines.
