Sewer treatment plants do not remove all potentially harmful chemicals and materials from waste water. Water that goes into storm drains is not treated at all.

When we toss household hazardous waste in the trash it goes to a landfill or trash incinerator. In landfills, toxins leach out of open, broken, or corroded containers into the air and soil, and percolate into water aquifers or run off into waterways. It may also blow up, catch on fire, or combine to create even more dangerous compounds. If burned, household hazardous waste emits toxins into the air and sometimes generates even more toxic byproducts.

Below are a few examples of how improperly disposed of household hazardous waste harms people and the environment.

Motor Oil

Motor Oil - Household Hazardous WasteWhile in use, motor oil and oil filters pick up heavy metals like lead, arsenic, cadmium, and chromium. Used motor oil and oil filters can contaminate water and soil.

Used motor oil is insoluble, coats everything it comes in contact with including plants and animals, and is slow to degrade. The amount of oil from a single oil change (4 quarts) can contaminate 1 million gallons of water.

Solvents

Solvents are what make oil-based paints, stains, and varnishes spreadable. The solvents evaporate into the air leaving behind the coating. Solvents are also used in paint remover, thinner, and cleaner.

Oil-based solvents contain mineral spirits (naphtha) or petroleum distillates (toluene, xylene) that are toxic and flammable. They release volatile organic compounds (VOCs) which are powerful greenhouse gases (worse than methane). These solvents break down in sunlight producing photochemical pollutants like benzene which is highly toxic. Oil-based solvents are persistent pollutants meaning they hang around a long time.

Poisons

Plants Killed by Herbicide - Household Hazardous WasteAmericans use fungicides, herbicides, insecticides, pesticides, and rodenticides to kill pests around our yards and homes.

These products contain poisons such as atrizine, cypermethrin, diazinon, glyphosate, and malathion to name a few. Household poisons disposed of incorrectly can harm plants and wildlife and contaminate our drinking water.

Mercury Containing Products

Household items that contain mercury include button cell batteries, thermostats, fluorescent light bulbs, old style thermometers, and electronics. Mercury is released into the air, soil, and water by broken, damaged, or burned products.

Mercury exposure can affect the nervous system and harm the brain, heart, kidneys, lungs, and immune systems of people, fish, and animals. A highly toxic form of mercury, methylmercury, builds up in fish and the people and animals that eat them.

Options for Disposing of Household Hazardous Waste Safely

There are numerous ways to get rid of household hazardous waste in a safe and environmentally sound manner. Options vary by area and include:

  • Curbside Collection – some communities provide curbside collection, especially of products that can cause a lot of damage like motor oil.
  • Drop Off Facilities – are often co-located with landfills. Residents can typically drop off a limited amount of household hazardous waste for free.
  • Collection Events – cities, counties, nonprofit organizations, schools, and even sports teams hold periodic events for people to bring in and drop off household hazardous waste.
  • Reuse Programs – unused or leftover items like paint are collected and made available to the general public for free.
