What You'll Learn
Minimise rainfall runoff
Minimising rainfall runoff is an important step in preventing lake pollution. Rainfall or snowmelt can move over and through the ground, picking up and carrying pollutants into lakes. This is especially true in urban and suburban areas, where the land surface is often covered by buildings, pavement, and compacted landscapes that increase runoff.
To minimise rainfall runoff, it is important to reduce the amount of impervious surface in the watershed area, such as driveways and parking lots, and encourage infiltration. This can be done by planting vegetation around the lake and on slopes, which will absorb rainwater before it reaches the lake and help to filter out pollutants. Vegetation can also be used to create a buffer strip along shorelines to prevent erosion and trap sediment.
Another strategy is to use permeable paving surfaces around the lake, which allow rainwater to infiltrate the ground rather than running off into storm drains. Sustainable gardening and landscaping practices can also help to minimise rainfall runoff. This includes reducing the use of chemical fertilizers, pesticides, and herbicides, as well as avoiding fertilizing before a rainstorm.
Additionally, maintaining and properly managing septic systems can help to prevent the discharge of pollutants into lake waters. Regular inspections, maintenance, and pumping of septic systems are necessary to prevent failure and potential pollution of nearby lakes and streams.

Implement a lake management plan
Implementing a lake management plan is essential to ensure the long-term health and sustainability of a lake. A comprehensive plan should include clear goals, management strategies, and a water-quality monitoring system. Here are some key components to consider when creating and implementing a lake management plan:
Identify Sources of Pollution
Understanding the sources of lake pollution is crucial for developing effective solutions. Pollution can come from various sources, including urban development, agricultural practices, and human activities. For example, pollutants can enter the lake through stormwater runoff, sewage discharge, or direct dumping of trash and chemicals. Identifying these sources will help in tailoring specific mitigation strategies.
Reduce Stormwater Runoff
Stormwater runoff is a significant contributor to lake pollution. Implementing measures to minimize the amount of pollutant-laden water reaching the lake is essential. This can be done by planting vegetation, such as buffer strips, around the lake and its shoreline. These plants will absorb rainwater, filter out pollutants, and trap sediments before they reach the lake. Additionally, using permeable paving surfaces and minimizing impervious surfaces like concrete can help reduce runoff and encourage infiltration.
Improve Sewage Treatment
Upgrading sewage treatment plants is crucial to reducing nutrient pollution. Human sewage is a common source of pollution, and by improving the treatment process, cleaner water can be discharged into the lake. This can involve investing in advanced wastewater treatment technologies, such as non-chemical systems, to effectively remove suspended solids and improve oxygen transfer efficiency.
Promote Proper Waste Disposal
Encouraging proper disposal of household chemicals, pharmaceuticals, and hazardous materials is vital. Educating the community about the importance of responsible waste management will help prevent these pollutants from entering the lake. This includes disposing of animal waste properly, avoiding flushing medications, and ensuring that yard waste, such as grass clippings and leaves, does not end up in the lake or storm drains.
Control Erosion
Lakeshore erosion can lead to increased sedimentation in the lake, causing turbidity and harming aquatic life. Establishing a vegetated buffer along the shorelines can help stabilize the soil and prevent erosion. Additionally, using erosion control products, such as silt fences or coir logs, can effectively reduce sediment infiltration into the lake, maintaining water clarity.
Monitor and Adapt
Regular monitoring of water quality is essential to track the effectiveness of the implemented strategies. Monitoring can be done through partnerships with aquatic experts or government agencies specializing in environmental conservation. By continuously evaluating the lake's health, management plans can be adapted, and new strategies can be incorporated as needed to ensure the long-term sustainability of the lake ecosystem.

Upgrade sewage treatment plants
Upgrading sewage treatment plants is crucial in preventing lake pollution, as sewage is the most common urban source of nutrient pollution in lakes. Here are some detailed suggestions to upgrade sewage treatment plants and reduce their negative impact on lakes:
Implement Non-Chemical Wastewater Treatment Systems
Moleaer, for example, offers a non-chemical wastewater treatment system that has proven highly effective in removing pollutants. In trials, their system achieved a 99.65% reduction in total suspended solids and 85% oxygen transfer efficiency. Non-chemical systems can reduce pollution without causing further chemical contamination.
Obtain Necessary Permits and Utilize Latest Technologies
According to the National Pollutant Discharge Elimination System (NPDES), established by the Clean Water Act, sewage treatment plants must obtain permits from the state and EPA before discharging waste or effluents into bodies of water. Treatment plants must also employ the latest technologies to treat effluents and minimize pollutant levels.
Encourage Proper Waste Disposal
Educate households on the proper disposal of chemicals, pharmaceuticals, and hazardous materials to prevent them from entering the sewage system and, subsequently, water supplies.
Prevent Sewage Overflows and Leaks
Investing in larger pipes is not always the answer to preventing overflows. Instead, focus on natural solutions such as expanding wetlands, restoring wetlands, creating green roofs, and planting vegetation to absorb rainwater and reduce the amount of stormwater entering the sewer system.
Implement Strong Notification Programs
In the event of untreated sewage release, it is crucial to notify the media, citizens, and environmental agencies promptly. This not only protects public health but also raises awareness and support for initiatives to reduce sewage pollution.
Upgrading sewage treatment plants is a critical step in preventing lake pollution and ensuring the long-term health of lakes and the people and ecosystems that depend on them.

Establish a vegetated buffer strip
Establishing a vegetated buffer strip is an effective way to prevent lake pollution. This method involves planting vegetation, such as shrubs, grasses, and trees, along the shoreline of a lake, creating a natural barrier between the land and the water. This buffer strip helps to filter and absorb pollutants before they reach the lake, improving water quality and providing multiple environmental benefits.
One of the key functions of a vegetated buffer strip is to trap and filter sediments and pollutants carried by stormwater runoff. When rain falls on impervious surfaces like concrete, it picks up contaminants and flows towards the lake. The buffer strip acts as a natural filter, trapping sediment and absorbing nutrients, pollutants, and excess water, preventing them from entering the lake. This helps to reduce lake turbidity, or cloudiness, caused by excess sediment, and protects the lake's aquatic life and vegetation.
Vegetated buffer strips also play a crucial role in discouraging waterfowl, such as geese, from accessing the lake. Waterfowl can contribute a significant amount of waste to the lake, with the average goose producing up to one pound of droppings per day. By establishing a buffer strip, you create a natural barrier that discourages geese and other waterfowl from approaching the lake, thereby reducing the amount of waste entering the water.
Additionally, the vegetation within the buffer strip provides habitat and food sources for various wildlife species, including birds, insects, and small mammals. This helps to support biodiversity and enhance the overall health of the ecosystem surrounding the lake. The roots of the vegetation also help to stabilize the shoreline, reducing erosion and preventing nutrient-rich sediment from entering the lake, further improving water quality.
When establishing a vegetated buffer strip, it is important to select plant species that are native to the region and well-suited to the local climate and soil conditions. This ensures that the plants can thrive and effectively perform their filtering and absorption functions. By carefully planning and maintaining the buffer strip, you can create a natural and sustainable solution to prevent lake pollution.

Avoid fertilisers and pesticides
Fertilisers and pesticides are a major source of nutrient pollution, which is a key factor in the degradation of lake water quality. Nitrogen and phosphorus, the nutrients present in fertilisers, occur naturally in the environment, but high levels are detrimental to lakes. When soil-test nitrogen and phosphorus increase, greater amounts move with water, increasing the risk of contaminating lakes. This leads to eutrophication, where a water body becomes abundant in aquatic plants and low in oxygen content.
To prevent this, it is important to minimise the use of fertilisers and opt for organic, no-phosphate or slow-release alternatives when necessary. Analysing lawn soils prior to applying fertiliser is a good non-structural way to prevent fertiliser pollution. It is also important to keep yard waste, such as grass clippings and leaves, away from lakes, as they are high in nutrients that can contaminate the water when they decompose.
Pesticides are harmful to aquatic organisms and can cripple the delicate lake ecosystem. They poison indiscriminately, meaning that they harm or kill beneficial insects and plants, such as honeybees and lady beetles, in addition to the targeted pests. Pesticides can also be fatal and cause illness in humans, particularly children and pets.
To avoid the use of pesticides, it is recommended to focus on landscaping that uses native plants. These plants are adapted to the local environment and do not require watering or maintenance. This helps to maintain the beauty of the natural forest areas surrounding lakes while eliminating the need for pesticides.

Frequently asked questions
Lake pollution occurs when contaminants such as debris, trash, chemicals, sewage, fertilizers, bacteria, and microorganisms enter water bodies. Pollution can also be caused by land and air pollution, which eventually settle in water bodies, harming fish, plants, and other life forms.
The sources of lake pollution vary in different parts of the world. In some places, it is caused by urban development, with natural land being replaced by concrete and other impervious surfaces. In other places, the major sources of pollution are fertilizers and pesticides.
Lake pollution can lead to an increase in nutrient levels within the water, causing algae to grow and possibly resulting in harmful algae blooms (HABs). When the algae die and decay, they consume oxygen in the water, leading to a lack of oxygen for invertebrates and fish, causing them to suffocate.
Lake pollution can be prevented by implementing proactive measures, enforcing regulations, and using innovative technologies. At an individual level, people can avoid pouring oil, chemicals, or other contaminants down sinks or drainage systems. Proper waste disposal of household chemicals, pharmaceuticals, and hazardous materials is also crucial. Additionally, vegetation can be planted around lakes to absorb nutrients, filter out pollutants, and trap sediments.
