Preventing Runoff Pollution: Strategies For A Cleaner Environment

Runoff pollution is caused by water running off driveways, patios, and walkways, and carrying pollutants into our water supply. To prevent this, we need to keep pollutants away from the runoff's path. This can be done by installing permeable surfaces that allow water to penetrate and be absorbed into the soil. Other methods include using a car wash that recycles water, sweeping and composting grass clippings and leaves from outdoor surfaces, and implementing landscaping projects that slow, catch, use, or filter rainwater or snowmelt.

Install permeable surfaces to absorb water into the soil

One of the most effective ways to prevent runoff pollution is to install permeable surfaces that allow water to penetrate and be absorbed into the soil. Driveways, patios and walkways are major contributors to runoff pollution when they direct water off our properties. By installing permeable surfaces, we can stop the runoff at its source.

There are several options for permeable surfaces that can be installed. One option is to use interlocked stone parking spots, which can be safely ploughed and also reduce the appearance of ice slicks during freeze and thaw cycles. Another option is to install an artesian well, also known as a dry well, which is a large hole filled with loose rock.

In addition to permeable surfaces, there are other ways to prevent runoff pollution. For example, using a car wash that recycles water or washing your car on the lawn with a bucket can help to filter soapy runoff. Sweeping and composting grass clippings and leaves from driveways, streets and walkways can also reduce pollutants.

Landscaping projects can also help to slow, catch, use and/or filter rainwater or snowmelt, reducing the effects of runoff pollution. Soil high in organic content retains much more water than other types of soil and compost is an excellent source of this type of soil.

It is also important to keep pollutants safely away from the runoff's path. Only clean rainwater should go into the storm drain. Proper maintenance of neighbourhood stormwater ponds, which are designed to capture and treat stormwater runoff, can also help to prevent pollution.

Sweep and compost grass clippings and leaves from driveways

Sweeping and composting grass clippings and leaves from driveways, streets, and walkways is an effective way to prevent runoff pollution. This simple act can help to reduce the amount of organic matter and nutrients that end up in our waterways, which can cause harmful algal blooms and other water quality issues.

When grass clippings and leaves are left on hard surfaces like driveways, they can easily be washed away by rainwater or irrigation water. This water then carries these organic materials into storm drains and nearby water bodies, contributing to runoff pollution. By sweeping and composting these clippings and leaves, we can remove a significant source of pollution from our environment.

Composting grass clippings and leaves is a natural and sustainable way to dispose of them. Composting involves allowing organic matter to break down over time, creating a nutrient-rich soil amendment. This process not only reduces waste but also provides a valuable resource for gardening and landscaping. Home composting bins or piles can be used to compost grass clippings and leaves, creating a convenient and eco-friendly solution.

Additionally, by regularly sweeping and maintaining our driveways and other hard surfaces, we can prevent the build-up of leaves and debris that can contribute to runoff pollution. This proactive approach helps to keep our local waterways clean and healthy. It is also important to note that proper disposal of grass clippings and leaves is crucial. Instead of discarding them in the trash, composting provides an environmentally friendly alternative.

Furthermore, the use of compost has additional benefits for our environment. Compost is an excellent source of soil with high organic content, which can help to improve water retention in the soil. By incorporating compost into our landscaping and gardening practices, we can reduce the need for excessive irrigation, further mitigating the impacts of runoff pollution. This approach aligns with the concept of watershed-friendly landscaping, which aims to minimise the negative effects of human activities on our water resources.

Use a car wash that recycles water

Using a car wash that recycles water is a great way to prevent runoff pollution. When you wash your car at home, the soapy water runs off your driveway and into the storm drain, carrying pollutants with it. These pollutants can include oil, grease, and dirt from your car, as well as any chemicals you use to clean it. By using a car wash that recycles water, you can help to keep these pollutants out of our water supply.

There are a few things to keep in mind when choosing a car wash that recycles water. First, make sure that the car wash actually recycles a significant portion of the water they use. Some car washes may advertise themselves as "water-saving" or "eco-friendly" but may not actually recycle much water. Look for car washes that use water recycling systems that can treat and reuse a high percentage of the water they use.

Another thing to consider is the location of the car wash. If the car wash is located in an area that is prone to flooding or has a high water table, the recycled water may end up seeping into the ground and potentially contaminating groundwater supplies. Look for car washes that are located in areas with good drainage and that have systems in place to manage the recycled water properly.

In addition to using a car wash that recycles water, there are a few other things you can do to reduce runoff pollution from car washing. One option is to wash your car on your lawn, where the soapy runoff will be filtered by the grass. You can also use a waterless car wash product, which uses less water and reduces the amount of runoff. These products typically come in the form of a spray or foam that you apply to your car, and then you wipe it off with a microfiber cloth.

Finally, you can reduce the need for car washing by keeping your car clean and free of dirt and debris. This can be done by regularly vacuuming the interior and using a duster or cloth to wipe down the exterior. You can also use a car cover when your car is parked to protect it from the elements and reduce the buildup of dirt and grime. By following these simple tips, you can help to prevent runoff pollution and keep our water supplies clean.

Install a rain barrel to capture roof runoff

Installing a rain barrel to capture roof runoff is a great way to prevent stormwater from reaching waterways and reducing the potential for pollution. Rain barrels are a simple and effective way to collect and store rainwater, which can then be used for various purposes such as watering plants or gardens. This helps to reduce the amount of stormwater runoff, which can carry pollutants and contaminants into our waterways.

To install a rain barrel, you will need to choose an appropriate location near your downspout. The barrel should be placed on a level surface and secured to prevent it from tipping over. You may also need to install a diverter to direct the rainwater into the barrel. It is important to ensure that the barrel has a tight-fitting lid to prevent mosquitoes and other pests from breeding in the stored water.

When choosing a rain barrel, consider the size and material that best suits your needs. Barrels typically range from 50 to 80 gallons, and you may need more than one depending on the amount of rainwater you intend to collect. Plastic barrels are a popular choice as they are lightweight and durable. However, you can also find barrels made from metal, wood, or ceramic.

Maintaining your rain barrel is important to ensure it functions properly and does not become a breeding ground for mosquitoes. Regularly clean and inspect the barrel, especially after heavy rainfall or periods of disuse. You should also consider treating the stored water with a mosquito larvicide to prevent mosquito breeding.

By installing a rain barrel, you can play an active role in reducing stormwater runoff and protecting our waterways from pollution. This simple and cost-effective solution not only helps the environment but also provides a valuable source of water for your garden or other outdoor needs. Remember to follow local guidelines and regulations regarding rainwater harvesting and take the necessary steps to ensure the safety and quality of the collected water.
