Household hazardous wastes should not be dumped down the sewer drain or dumped outside. They can be harmful to the environment and harmful to our treatment facility. These wastes, such as stain; paint; varnish; gasoline; kerosene; aerosol cleaners; ammonia or petroleum-based cleaners; rechargeable or lead acid batteries; adhesives; fertilizers; pesticides; weed killers; motor oil; and resins, should be properly disposed of.
