Car Care for Clean Water

We all know that cars cause air pollution and sometimes even noise pollution. But did you know cars also cause water pollution? Liquids that leak from your vehicle such as antifreeze, oil, grease, and transmission fluid run off into storm drains, which in turn can re-enter our water supply. Maintain your car and have it inspected regularly to reduce leakage. And turn down the radio.

Here are some common garage hazardous wastes:

  • Antifreeze
  • Transmission fluid
  • Brake fluid
  • Gasoline
  • Car batteries
  • Old paint/thinner
  • Wood stain and finishes

Used motor oil is the largest single source of pollution in our water. People often dump their used oil in the street or on the ground, which could end up back in our water. Recycle oil and antifreeze instead of using it to kill weeds and wildlife. Look for service stations that accept oil for recycling. Pets can die from consuming antifreeze (it tastes sweet.)

Don't throw old batteries in the trash or bury them. They contain hazardous chemicals that can soak through the soil and pollute our water. Plus, it's against the law. Instead look for recyclers located in the yellow pages under "Batteries Mfrs."

Things like antifreeze, battery acid, brake fluid, gasoline, and other auto products are dangerous toxins. Take special care not to drain or drip them onto the driveway or street.

 
Eco-friendly H2O Tips
  • Drain motor oil in a reusable, resealable container such as a milk jug.
  • Never mix used oil with other used automotive fluids.
  • Don't even think about tossing used oil in the trash or dumping it down a storm drain or on the ground.
  • Take used oil and oil filters to a recycling location.
  • Acid from old car batteries can leak into landfills, so don't put them in the trash. When you purchase a new battery, the dealer is required to take your old one in for a nominal fee.
  • Don't drain radiator fluid into the street. Use a resealable container and take it to an approved drop-off location.
  • Have your car inspected regularly and repair oil, antifreeze and other fluid leaks.
