Keep your car properly maintained. Stop any drips or leaks, from oil changes, wiper fluid, gasoline, etc., as soon as possible. Having those chemicals drip onto the ground make them available to be picked up by stormwater runoff. Which can carry the chemicals all the way to local waterways.

Motor oil and antifreeze can be recycled, and more importantly, should never be poured down a sink drain or sewer drain. Often this leads straight to local waterways anyway. Recycling centers, auto repair shops or gas stations may take your used chemicals, check with your local borough for information.

Also, when washing your car, go to a commercial car wash. Most commercial car washes recycle their water and some even use environmentally friendly chemicals.
