Too Toxic To Trash
Household hazardous waste (HHW) is considered to be any leftover or unused portions of chemical products you use in your kitchen, bathroom, garage, automobile, or yard. Household hazardous waste can pass through treatment processes or storm drains and get discharged into creeks, the San Francisco Bay, or the Pacific Ocean. For safety and environmental reasons, it is illegal to dispose of HHW in the garbage, sewers or storm drains.
Problems with Improper Disposal of Household Hazardous Waste
- Contaminates our waterways and drinking water.
- Physical injury to sanitation workers.
- Contaminates septic tanks or wastewater treatment systems if poured down drains or toilets.
- Presents hazards to children and pets if left around the house.
- Harms wildlife and the environment.
