Annual Household Hazardous Waste Round-Up

What?  Your annual opportunity to legally and responsibly dispose of poisonous, flammable, corrosive or other hazardous chemicals for FREE.*


*Households can dispose of 25 gallons or less of qualifying hazardous waste for free. Businesses disposing hazardous wastes will be charged disposal fees and must pre-register 10 days in advance — call or email Katie Fleming to register: 360-762-5821;

Why?  Proper disposal of hazardous materials protects you and your family, the workers who handle your waste, and the place we call home — it keeps harmful chemicals out of our bodies, our drinking water, and the environment around us.
