We drink it, swim in it, clean with it and can’t do without it. Water is one of our most precious natural resources, but often we don’t take much notice of it until there is too much or too little.

What can you do to help maintain an abundant, high quality water supply? A whole lot, actually. The first thing you need to know is that the water that travels over roofs, lawns, driveways and gutters ends up down storm drains, which run — unfiltered — into local lakes, streams, rivers and oceans. Because of this, you need to be careful what water can pick up. Take these steps to eliminate potential stormwater pollutants in and around your home:

Don’t Wash Away Fertilizers and Pesticides

Maintaining your lawn and garden can send fertilizers and pesticides into local waterways, causing algal blooms, fish die-off and drinking water contamination. Just one teaspoon of certain pesticides rinsed down a storm drain can show up as a pollutant in local streams. To prevent polluting the water:

1. Avoid using fertilizers or pesticides within 75 feet of wells or waterways.

2. Apply garden chemicals when it will not rain for a few days, or the rain will wash the chemicals away. Fertilizers and pesticides need time to be absorbed.

3. Do not water your lawn immediately after applying garden chemicals because that will wash them away, too.

4. Only apply garden chemicals where needed, and apply sparingly to reduce overall chemical runoff.

Keep Yard Waste Out of Drains

Grass, leaves and other yard waste that gets washed down storm drains generates green algae in lakes, suffocating fish and spoiling water recreation. Excessive yard waste can also clog storm drains, which can lead to flooding. It’s best to sweep, not rinse, your driveway, patio and walkways to keep these items out of the drains. Make sure to bag your green waste — anything you rake, mow or clip — or use it as healthy, easy fertilizer for your lawn or garden. Learn more about grasscycling.

Pick Up Pet Waste

Pet waste should go down the toilet or in the trash. Dog waste contains twice as much bacteria as human waste, and can also transmit viruses and parasites that are harmful to humans and other animals. Tapeworm, roundworm, E. coli and Parvo are just a few. The EPA has stated that pet waste is a major contaminant in our waterways. Pick it up regularly to keep these microbes from leaching into water sources.


car wash

Don’t Wash Your Car in Your Driveway

Washing your vehicle in your driveway can send toxic soap and oils into your local waterways. The best way to avoid this is to wash your car at a car wash, where the drains are better equipped to handle these chemicals. You can also use nontoxic, phosphate-free or biodegradable soap that will create less of an impact on humans and wildlife, or use rags and buckets to collect the dirty water and limit the amount of soapy runoff.


oil change

Don’t Dump Motor Oil and Auto Fluids

Keep motor oil and auto fluids out of storm drains. According to the EPA, the oil from one oil change can pollute one million gallons of fresh water. Check your vehicles regularly for leaks and spills so you can fix leaks promptly and soak up any spills with absorbent material like sand or kitty litter. Recycle used oil and other automotive fluids to keep them out of the drain or trash.


paint

Don’t Dump Paint and Solvents

Paint, paint thinners and solvents should be used in small amounts as directed, stored safely and cleaned up promptly if spilled. When rinsing paintbrushes, do so in a sink indoors, or in a sealed container of water that you can dispose of with other hazardous waste, and use only a minimal amount of water. Do not clean paintbrushes outside, and do not pour paint or other solvents down the storm drain, as they will not simply dissolve, and are highly toxic contaminants in our water supply.
