May 11 is Household Hazardous Waste Round-Up Day at the Dump

San Juan County's Household Hazardous Waste Round-Up is our annual opportunity to legally and responsibly dispose of poisonous, flammable, corrosive or other hazardous chemicals for FREE.*

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. 

Where? Lopez Solid Waste AKA the Dump (2419 Fisherman Bay Road)


When? Saturday, May 11, 2024; 10am to 2pm

  • Pesticides, fungicides and other poisons

  • Gasoline and other used fuels

  • Wood preservatives, solvents and thinners
