Stormwater pollution is a pressing issue that can have severe ecological consequences, including fish and wildlife habitat degradation. Stormwater runoff, which occurs when rain or snowmelt flows over impervious surfaces like streets, parking lots, and roofs, often carries pollutants such as bacteria, oil, trash, and chemicals into nearby water bodies. This can lead to unsanitary living conditions and even neighborhood flooding during heavy rainfall or snowmelt. However, there are several effective ways to mitigate stormwater pollution and minimize its impact on the environment. Implementing green infrastructure, such as rain gardens and permeable pavement, can help slow down and infiltrate stormwater, allowing natural filtration processes to occur. Additionally, individuals can play a crucial role in preventing stormwater pollution by properly disposing of waste, maintaining vehicles to prevent fluid leaks, and being mindful of fertilizer and chemical use.

What You'll Learn
Use green infrastructure to slow down stormwater
Green infrastructure is a sustainable way to manage stormwater and tackle urban water woes. It involves using natural elements like plants, soil, and natural systems to manage stormwater runoff. This approach is also known as low-impact development.
Green infrastructure helps to slow down stormwater by spreading it out over the land, allowing it to slowly soak into the ground. This process mimics natural hydrological processes and turns rainfall into a resource instead of waste. By using green infrastructure, plants can filter out pollutants from stormwater as it infiltrates the ground. Some examples of green infrastructure techniques include:
- Rain gardens: These are gardens designed to capture and filter stormwater runoff. They can be used to direct rooftop runoff and can also be installed in driveways and patios with permeable paving or patterns of cement and brick that allow water to filter through.
- Pervious pavement: This type of pavement is designed to be permeable, allowing water to seep through and reduce the need for extensive stormwater infrastructure like drains and retention basins. Permeable pavements are suitable for high-traffic areas and can handle heavy loads without compromising permeability.
- Rain barrels: These capture and store rainwater, recycling it for other uses such as watering gardens.
- Green roofs: Green roofs are vegetated rooftops that can retain a significant portion of rainwater, reducing the amount of runoff. The vegetation on green roofs also captures CO2, providing insulation and mitigating the urban heat island effect.
- Bioretention systems: These are engineered systems that use shallow, vegetated basins to collect and gradually filter stormwater through soil layers, mimicking natural processes.
By implementing these green infrastructure techniques, communities can effectively slow down stormwater, reduce flooding risks, enhance water quality, and provide a more sustainable approach to water management.

Reduce use of fertilizers and pesticides
Stormwater pollution is caused by a variety of factors, including human activities, that lead to pollutants entering storm drains and, eventually, nearby wetlands, streams, lakes, and rivers. Fertilizers and pesticides are among the most common pollutants, threatening water quality and killing fish and other aquatic life.
To reduce the use of fertilizers and pesticides, here are some detailed suggestions:
Firstly, it is important to minimize the use of chemical fertilizers and opt for organic alternatives. Fertilizer application should be done sparingly, well in advance of rainstorms, and always following the manufacturer's recommendations. Using organic slow-release fertilizers and implementing effective nutrient management practices can further reduce fertilizer runoff. Soil testing, for instance, helps determine precise fertilizer needs, minimizing excess application.
Farmers can also adopt nutrient management techniques, applying nutrients (fertilizer and manure) in the right amounts, at the right time of year, with suitable methods, and in the right places. This ensures that nitrogen and phosphorus, essential for crop growth, are fully utilized by plants, reducing their negative impact on water quality.
Additionally, consider using rain barrels or installing a rain garden. Rain barrels collect roof runoff, providing a natural source of water for lawns and gardens, reducing the need for chemical fertilizers. Rain gardens are another effective way to absorb stormwater runoff and utilize plants to filter out pollutants.
Furthermore, maintaining a lawn height of at least 3 inches can help minimize weed growth and reduce the need for pesticides. Leaving lawn clippings on the grass can also help block weeds and retain moisture, reducing the need for additional fertilizers.
By implementing these measures, individuals and farmers can play a crucial role in preventing stormwater pollution and protecting aquatic ecosystems.

Sweep up driveways and sidewalks
Stormwater pollution is a pressing issue, with unmanaged stormwater runoff causing serious damage to streams, lakes, and estuaries. This is especially true in areas with a lot of paved surfaces, where rainwater cannot pass into the soil, leading to water shortages.
One way to prevent stormwater pollution is to sweep up driveways and sidewalks. This simple act can have a significant environmental impact. Fertilizers, for example, are a common source of stormwater pollution, as they contain chemicals that can contaminate soil and groundwater. When it rains, these chemicals are washed into nearby storm drains, wetlands, streams, lakes, and rivers, leading to aquatic habitat degradation, algal growth, and toxicity in receiving water bodies. Therefore, it is essential to sweep up any fertilizers from driveways and sidewalks to prevent them from being washed away by rainwater.
Leaves, seeds, and flowers are other sources of stormwater pollution. They can contribute high levels of phosphorus to runoff, especially during the fall when leaves drop. Sweeping driveways and sidewalks regularly can help remove this organic matter and reduce the amount of phosphorus entering stormwater.
Street sweeping is also effective in removing other types of debris, such as sediment, vehicle debris, industrial emission particles, litter, and coarse organic sediments. This helps to reduce the amount of particulate matter in the air and prevents it from being entrained in the wind, improving air quality.
It is important to note that the type of sweeper used can impact the effectiveness of sweeping. Dry vacuum sweepers, for instance, are more effective at removing bacteria compared to other types of sweepers. Additionally, the timing and frequency of sweeping play a crucial role in its effectiveness. For example, sweeping in late winter and early spring can help remove residual road salt from impervious surfaces and decrease chloride loads.
Overall, sweeping driveways and sidewalks is a simple yet impactful way to prevent stormwater pollution. It helps to remove potential pollutants, such as fertilizers, leaves, and other debris, and improves both water and air quality. By adopting this practice, individuals can play a vital role in mitigating the negative effects of stormwater runoff on the environment.

Wash cars in areas where water can filter into the ground
Stormwater pollution is a pressing issue, particularly in urban areas with many impervious surfaces such as roads, parking lots, and rooftops, which prevent water from soaking into the ground and replenishing groundwater. This leads to water shortages and damage to streams, lakes, and estuaries. One significant contributor to stormwater pollution is car washing, with as many as 140 gallons of water, along with soap, surfactants, oil, and sludge, being washed down driveways and into storm drains, ultimately polluting rivers and lakes.
To prevent this, it is advisable to wash your car in an area where water can filter into the ground. Direct the wash water onto a lawn or landscaped area, allowing it to slowly percolate through the soil. This simple act can make a significant difference in reducing stormwater runoff and the pollution it causes.
When washing your car in such an area, it is essential to use only soaps, cleaners, or detergents labeled non-toxic, phosphate-free, or biodegradable. Using a bucket of soapy water instead of applying soap directly to the sponge is also recommended. Wring sponges and rags into the bucket, not onto the ground, and never empty buckets onto driveways, streets, or other paved areas.
In addition to these measures, you can further reduce pollution by regularly checking and repairing fluid leaks in your car and recycling motor oil and other automotive fluids. Never dump motor oil or other engine fluids down storm drains or onto the ground. Properly disposing of these fluids and recycling motor oil can help prevent them from contaminating water bodies.

Properly dispose of trash, including cigarette butts
Cigarette butts are one of the most common types of litter, making up an estimated 30% of total litter along US shorelines, waterways, and on land. They are often disposed of in trash bins or tossed onto the ground, ending up in landfills. However, this is not the correct way to dispose of cigarette butts as they are toxic and hazardous waste, containing thousands of different compounds that can leach into the environment. When not properly disposed of, cigarette butts can end up in stormwater runoff, which carries them into nearby storm drains, wetlands, streams, lakes, and rivers, causing pollution and damaging these water bodies.
To properly dispose of cigarette butts, it is important to treat them as hazardous waste. Collect all your cigarette butts in a sealed container, such as a jar or a can with a lid. Do not throw them in the trash or flush them down the toilet, as they can still end up in landfills or water bodies. Instead, dispose of them at a specialized facility or collection point that accepts hazardous waste. Some local governments may provide collection points for hazardous waste disposal, and you can contact your local waste management authority to inquire about any such programs in your area.
If you are unable to access a hazardous waste disposal facility or collection point, you can also practice proper waste management techniques to minimize the impact of cigarette butts on the environment. This includes never throwing cigarette butts on the ground or in bodies of water, and ensuring that trash bins are secure and inaccessible to wildlife. Additionally, you can advocate for extended producer responsibility (EPR) laws, which would make the producers of cigarettes partially responsible for collecting and recycling the cigarette butts.
Properly disposing of trash, including cigarette butts, is crucial to preventing stormwater pollution and protecting our environment. By following the correct disposal methods, we can reduce the toxic impact of cigarette butts on our water sources and natural habitats.
