Hazardous household waste

Hazardous household waste (HHW) consists of materials that are toxic and should never be thrown in the garbage, dumped on land, or poured down the drain or sewer.

Many common household products contain hazardous chemicals that can pose a threat to living organisms if released into the environment, contaminating the air, water, and/or soil. Pesticides, fertilizers and other products can run off lawns and gardens into storm drains and streams, polluting fresh water. Solvents can escape into the atmosphere from the normal use of cleaners, paints and aerosol sprays, as well as accidental spills or improper disposal. Storing old chemicals around the house can be a potential fire hazard, as well as a potential threat to your children and pets.
