Reduce the use of fertilizers, herbicides, and pesticides
Reducing the use of fertilizers, herbicides, and pesticides is crucial for mitigating river pollution. These substances are significant contributors to water degradation, particularly in agricultural contexts. Here are some measures to address this issue:
Agricultural Practices
Farmers play a pivotal role in reducing fertilizer and pesticide usage. They can adopt nutrient management techniques, ensuring that fertilizers and manure are applied in the appropriate amounts, at the right time of year, with suitable methods, and in the correct placement. This minimizes the risk of excess nutrients reaching water bodies and causing eutrophication, which leads to "dead zones" and aquatic life loss. Proper nutrient management also helps prevent harmful algal blooms (HABs) in freshwater systems, which can produce toxins detrimental to both wildlife and humans.
Alternative Landscaping
Landscaping with native plants is a recommended practice. Native grasses and plants require less watering and fertilizing compared to non-native species, reducing the potential for fertilizer runoff. Additionally, implementing Bay-friendly landscaping on community property near water bodies can help minimize stormwater runoff and foster a collective sense of environmental stewardship.
Livestock Management
Managing livestock access to streams is essential. Farmers can install fences along streams, rivers, and lakes to prevent animals from entering and depositing waste directly into the water bodies. This simple measure helps keep nitrogen and phosphorus levels in check, protecting both the stream banks and the water quality.
Proper Disposal and Runoff Prevention
Improper disposal and runoff of pesticides and fertilizers are significant concerns. These substances can enter storm drains, indoor drains, and groundwater, eventually finding their way into rivers, streams, and oceans. It is crucial to dispose of these chemicals responsibly and to prevent spills or illegal dumping. Additionally, adopting integrated pest management practices and exploring less toxic alternatives can help minimize the environmental footprint of pesticides.
Community Education and Collaboration
Educating communities about the impact of fertilizer and pesticide usage is vital. Initiatives such as storm drain stenciling can remind community members that only rainwater should enter storm drains, as contaminants often end up in waterways. Collaboration between farmers, stakeholders, conservation groups, educational institutions, and community groups is essential for reducing nutrient pollution and fostering sustainable practices.

Avoid antibacterial products with triclosan
Water pollution is a widespread problem that jeopardizes our health. Our rivers, reservoirs, lakes, and seas are filled with chemicals, waste, plastic, and other pollutants. Water pollution occurs when harmful substances contaminate a body of water, degrading water quality and rendering it toxic to humans and the environment.
Everyday tasks such as washing your hands or brushing your teeth can contribute to river pollution. Hand gel, toothpaste, mouthwash, detergents, and disinfectants may contain anti-bacterial agents such as triclosan, which has been found in nearly 58% of freshwater streams. When we wash our hands or brush our teeth, we are likely putting triclosan into our water sources.
Triclosan mimics the hormone estrogen in animals and can inhibit their reproductive systems and ability to swim. It can also disrupt thyroid hormone-associated gene expression and is linked to neurodevelopment impairment, metabolic disorders, cardiotoxicity, and increased cancer risk. As triclosan breaks down, it can turn into other harmful compounds, such as dioxin, a highly toxic compound.
To avoid contributing to river pollution, choose not to use products that contain triclosan. Some companies have started removing triclosan from their products, so look for alternatives that do not contain this antibacterial agent. By making small changes to your everyday habits, you can help improve the water quality of your local river.

Don't use slug pellets with metaldehyde
While it is important to address the role of large factories and heavy industries in river pollution, individual actions can also contribute to the problem. One such action is the use of slug pellets containing metaldehyde, which can have harmful effects on the environment and contribute to river pollution.
Metaldehyde is a toxic chemical that is commonly found in slug pellets, and it is effective in killing slugs by causing them to dehydrate. However, when these pellets are used outdoors, they can be washed into drains and ditches, eventually making their way into river systems. This becomes an issue when other animals, such as birds or hedgehogs, consume the poisoned slugs or are exposed to the chemical directly. The toxic effects of metaldehyde can then be passed up the food chain, posing a risk to larger predators and aquatic life.
Additionally, metaldehyde has been linked to poisoning in pets, such as dogs and cats, and can disturb natural ecosystems. In some countries, slug baits containing metaldehyde have been banned due to their toxic effects on animals. While the use of metaldehyde slug pellets was temporarily banned in the UK in 2020 to protect wildlife, the ban was overturned in 2019. However, the British government reinstated the ban on outdoor use after March 2022.
To reduce the impact of slug control on the environment, individuals can consider alternative methods and products. Ferrous phosphate-based pellets, for example, are an effective alternative that does not carry the same risks to wildlife as metaldehyde. Other methods include cultural techniques such as planting slug-resistant crop varieties, selectively timing irrigation and harvest, and sowing seeds more deeply into the soil. It is important for individuals to be aware of the potential harm caused by metaldehyde and to choose less toxic alternatives to protect our rivers and natural ecosystems.
By avoiding the use of slug pellets containing metaldehyde and exploring alternative options, individuals can play a crucial role in reducing river pollution and creating a cleaner and greener environment for future generations.

Cut down on single-use plastics
Single-use plastics are a major threat to environmental and human health. They are a significant source of pollution in rivers, as they break down into smaller fragments, known as microplastics, which can be ingested by aquatic animals and release toxic chemicals. To reduce the use of single-use plastics, individuals can make simple changes in their daily lives.
One way to cut down on single-use plastics is to avoid purchasing bottled water whenever possible. By making this one change, you can significantly reduce the number of plastic bottles that end up in landfills and incinerators or, worse, in rivers and oceans. Instead, opt for a reusable water bottle that you can refill as needed.
Another way to reduce single-use plastic consumption is to bring your own bags, cups, or containers when shopping or getting takeout. This not only reduces the amount of plastic waste generated but also saves you money, as some businesses charge extra for single-use shopping bags or containers. Reusable totes, bags, cups, and containers are becoming increasingly popular and can be easily found or purchased.
In the bathroom, there are numerous opportunities to cut down on single-use plastics. Consider switching to bar soap, shampoo bars, bamboo toothbrushes, plastic-free floss, plastic-free deodorant, and menstrual cups. These alternatives are not only better for the environment but can also save you money in the long run.
The kitchen is another hotspot for single-use plastics. You can reduce plastic waste by cooking more often and storing leftovers in reusable containers instead of using plastic takeout containers. Avoid individually packaged goods, such as snack packs, and opt for buying dried pantry staples in bulk. Bring your own containers to the grocery store or use reusable bags to avoid using the plastic bags provided.
Making these simple changes in your daily habits can have a significant impact on reducing single-use plastic pollution in rivers and improving the health of our planet.

Vote for land use and conservation policies
One of the most important actions an individual can take to reduce river pollution is to vote for land use and conservation policies. This means advocating for thoughtful and responsible land use policies that prioritize environmental protection and the preservation of water quality.
Land use policies play a crucial role in reducing river pollution by regulating how land is utilized and developed. This includes implementing measures to minimize the negative impacts of urbanization, such as increased stormwater runoff, which contributes to downstream flooding, stream bank erosion, and pollution. For example, policies can encourage the use of permeable surfaces in urban areas to reduce the volume of stormwater runoff and promote natural solutions like planting rain gardens or connecting downspouts to rain barrels, allowing rainwater to infiltrate the ground instead of flowing directly into waterways.
Additionally, land use policies can address agricultural practices, which are a significant source of river pollution. Policies can promote sustainable farming methods to reduce nutrient runoff and prevent the contamination of nearby waterways. This includes educating farmers on best management practices (BMPs) for fertilizer management, such as modifying fertilizer types and amounts based on soil needs, and implementing buffer zones, like riparian corridors, to filter pollutants from stormwater before it reaches rivers.
Conservation policies, on the other hand, focus on protecting and restoring natural environments, including rivers and their surrounding ecosystems. These policies aim to preserve the health and integrity of river ecosystems, ensuring they remain resilient and capable of filtering and purifying water. Conservation policies can include initiatives such as reforestation efforts along riverbanks, which stabilize soil and prevent erosion, while also providing habitat for wildlife.
By voting for land use and conservation policies, individuals can help shape the decisions that impact their local rivers and waterways. These policies provide a framework for responsible land management and environmental protection, ensuring that the actions of humans do not compromise the health and functionality of these vital ecosystems.
Being an informed voter means staying updated on current issues and advocating for policies that address river pollution. This may involve engaging with local communities, participating in discussions, and supporting organizations dedicated to environmental protection, such as the Chesapeake Bay Foundation, which provides resources and initiatives to promote clean rivers and streams.
