7 Tips to Reduce Stormwater Pollution This Spring!

With over 10 million people living in the state of North Carolina, state residents’ day to day activities have an impact on water quality. Stormwater is surface runoff that does not soak into the ground during precipitation events (drizzle, rain, snow, and hail). As stormwater flows over neighborhoods, businesses, and streets, it picks up the trash, cigarette butts, pesticides, motor oils and other contaminants accumulated on hard surfaces and deposits them into our local creeks, rivers, and the ocean UNTREATED! Stormwater runoff is the #1 source of water pollution and the biggest threat to water quality in the state.

So what can you do? Here are some easy ways you can improve water quality this spring!

1. Don’t Over-Apply Fertilizer! Why?

Premature Plant Death

Over-application of synthetic or chemicals fertilizers can increase soil salinity and root burn in the long run, which may result in your plants not being able to properly absorb water and nutrients in the soil, leading to their untimely demise. Overuse of synthetic fertilizer can also disrupt soil chemistry and actually do damage to soils.

Harmful to Aquatic Life and Humans

When excess fertilizer gets into our storm drain system and travels into our waterways and oceans, algae blooms can form resulting in a loss of oxygen in the water. Algae blooms pose a direct threat to aquatic animals, which need to breathe just like we do!

A well-maintained, natural lawn care system requires little to no fertilizer. Talk to your local garden center about how to care for your landscape and if you must fertilize, what products you can purchase that are organic and environmentally friendly.

2. Sweep, Don’t Hose!

Sweep around your house and driveway vs. hosing to clean away the accumulated dirt and debris. When you sweep, pick up the debris and place it into the appropriate trash receptacle. Potentially impactful items and debris picked up and placed in the trash are less likely to get into the storm drain system and degrade water quality.

3. Take Your Car to A Car Wash

Spring is a great time for cleaning up inside and outside the home. However, when you spruce up your car, think of going to a local car wash vs. hosing it down at home. This actually saves water and reduces runoff to our waterways that contains soap and debris.

A standard garden hose uses about 10 gallons per minute. If you wash your car for 10 minutes, you might consume 100 gallons of water. While hosing with an automatic shut-off valve may save more water, it’s still recommended to take your car to a commercial car wash that can properly dispose of harmful runoff (debris, oil, harmful soaps, etc.). Commercial car washes also have sophisticated reclamation systems that enable them to re-use water, so they only expend approximately 9-15 gallons of water during any given wash cycle.

4. Plant Native Plants

Native plants are the foundation of a natural ecosystem. They provide biodiversity and give critters ample food and habitat, creating a sustainable ecosystem in your yard. Native plants also thrive in their “home” environment, requiring less water to thrive. Check out this list of North Carolina’s recommended native species here!

5. Make Your Landscape Water-Friendly

Consider installing green infrastructure practices like permeable pavers, rain barrels, French drains, bioswales, or reducing lawn areas altogether. When you use these practices to control the flow and sinking of water in your landscape, you’re helping to keep toxins and debris out of the storm drain system as well as capture water naturally — a WIN-WIN for you and the environment.

6. Scoop Your Pet’s Poop!

With warmer weather comes more walks with your fuzzy friend in the outdoors. Always remember to clean up after your pet’s waste and place it in the trash. Pet waste contains harmful bacteria that will wash into our waterways after a rainfall- which there is plenty of in the spring!

7. Drain Swimming Pool Safely

If you have a pool, drain it only when a test kit does not detect chlorine levels. Whenever possible, drain your pool or spa into the sanitary sewer system, where it will be treated. Also, store pool and spa chemicals in a covered area to prevent leaks and spills to the stormwater system.
