Recycling and Sustainability

Any unused or leftover chemical products in your home such as cleaners, paints, paint thinner, nail polish and polish remover, and lawn care products can be a potential danger to you, your family, and the environment. Household hazardous waste is usually labeled DANGER, WARNING, TOXIC, CAUTION, POISON, FLAMMABLE, CORROSIVE, or REACTIVE. It is dangerous and illegal to dispose of these materials as municipal solid waste. Protect you and your family's health, help us keep toxic chemicals out of the environment, and reduce pollution. 

  • DON'T POUR IT DOWN A SINK DRAIN. Some household hazardous waste can bypass the Wastewater Treatment Plant unchanged, polluting water downstream. 
  • DON'T POUR IT INTO DITCHES, STORM DRAINS, OR GUTTERS. Household hazardous waste will travel directly to waterways polluting ponds, lakes, and rivers. 
  • DON'T BURN IT. You risk producing poisonous fumes, contributing to air pollution or causing an explosion.
  • DON'T THROW IT IN YOUR TRASH BIN. These chemicals present safety hazards to solid waste collection workers.
  • DON'T DUMP IT OR BURY IT. These chemicals could leach through the soil and contaminate groundwater.
