What You'll Learn
Sewage overflows and wastewater
Sewage overflows, also known as sanitary sewer overflows (SSOs), occur when there is an unintentional discharge of raw sewage from municipal sanitary sewers. These overflows can be caused by various factors, such as blockages, line breaks, stormwater infiltration, and inadequate sewer design or maintenance. When these systems are overwhelmed or defective, raw sewage can leak into nearby bodies of water, including coastal areas and beaches. According to the EPA, there are at least 23,000 to 75,000 SSOs in the United States each year, making them a significant source of wet weather discharge.
Combined sewer systems (CSSs) are another factor in sewage overflows. CSSs are designed to collect rainwater runoff, domestic sewage, and industrial wastewater in the same pipes. During heavy rainfall or when the system is overloaded, CSSs can overflow and discharge untreated wastewater directly into nearby water bodies, including coastal areas. This can result in the release of raw sewage, industrial wastewater, and stormwater, leading to beach closures and environmental damage.
The impacts of sewage overflows and wastewater pollution on beaches are far-reaching. Firstly, they pose a serious health risk to humans. Sewage can contain bacteria, viruses, and parasites that can cause gastrointestinal issues, rashes, skin and eye infections, and flu-like symptoms. Additionally, sewage discharges can fuel harmful algal blooms (HABs) by introducing excess nutrients into coastal ecosystems. These algal blooms can release toxins that sicken humans and wildlife, contributing to fish kills and coral reef die-offs.
Furthermore, beach pollution from sewage and wastewater can have economic consequences. Polluted beaches may need to be closed to protect public health, impacting coastal tourism and recreational activities that contribute significantly to local economies. Property values can also decrease, and economic growth in the community can be inhibited due to the degraded beach environment.
Addressing sewage overflows and wastewater infrastructure issues is crucial to mitigating these impacts. This includes improving wastewater treatment processes, repairing and upgrading infrastructure, and implementing robust beach water quality monitoring programs to ensure the protection of public health and the environment. By taking these steps, we can work towards preserving the ecological, recreational, and economic value of our beaches.

Plastic pollution
The presence of plastic in the ocean has devastating consequences for marine life and ecosystems. Animals can become entangled in plastic debris, leading to suffocation, laceration, and internal injuries. They may also ingest plastic, mistaking it for food, which can cause starvation, infections, and even death. According to research, 17% of the species affected by plastic pollution are on the International Union for Conservation of Nature Red List of Threatened Species. Additionally, floating plastic items can facilitate the spread of invasive species, further threatening marine ecosystems, biodiversity, and the food web.
Microplastics, which form when plastic breaks down into smaller pieces, have now become a part of the food chain. They have been found in drinking water, salt, beer, soil, human tissues, blood, placentas, and reproductive organs. These microplastics can carry toxic chemicals, affecting both human and animal health. The impact of plastic pollution on human health is not limited to the ingestion of microplastics. Plastic materials are carcinogenic and can disrupt the body's endocrine system, leading to developmental, neurological, reproductive, and immune disorders.
The economic costs of plastic pollution are also significant, estimated to be between $6-19 billion USD annually. These costs arise from the impact on tourism, fisheries, aquaculture, and cleanup efforts. Coastal communities bear the brunt of these cleanup costs, as they struggle to remove plastic waste from their beaches.
To address plastic pollution, it is crucial to improve waste management strategies, especially in low-to-middle-income countries where plastic emissions are highest. Reducing plastic production and transitioning to recycled materials can also play a role in mitigating this global crisis.

Oil spills
Wildlife is particularly vulnerable to the harmful effects of oil spills. Birds that feed along the shoreline may have their feathers coated in oil, causing them to lose their ability to stay warm, often leading to death. Shore creatures, such as snails and clams, may survive by retreating into their shells, but many other organisms are injured or killed. Oil spills also contaminate the foraging and nesting grounds of various animals, including endangered species, disrupting their natural habitats and reproductive cycles.
The impact of oil spills on beaches can be long-lasting. While some oil will naturally break down and disappear due to sun, wind, and waves, thick layers of oil can persist for decades in certain environments, such as armoured gravel beaches. Oil pollution can also have economic and social consequences, affecting coastal economies that depend on tourism and recreational activities. Beach pollution due to oil spills can lead to beach closures, impacting local businesses and communities that rely on these beaches.
The clean-up process after an oil spill is crucial but challenging. In the case of the 2024 Singapore oil spill, the government deployed oil-absorbent container booms and used dispersant chemicals to break down the oil into droplets, enhancing biodegradation. However, even with the help of volunteers, the clean-up process can be lengthy, and some environmental damage may be irreversible.

Fertilizer and chemical runoff
Fertilizers and chemicals from farms, factories, and households are released into rivers, streams, and estuaries, causing water degradation and negatively impacting coastal ecosystems. This type of pollution, known as nonpoint source pollution, originates from various sources, including septic tanks, vehicles, farms, and timber harvest areas.
Fertilizer runoff is a significant contributor to water pollution. When fertilizers are applied to lawns or agricultural lands, they can become vulnerable to runoff during heavy rain or snowmelt. The water carries the fertilizer residues and chemicals, contaminating water supplies and leading to soil erosion. This polluted water flows into storm drains, rivers, lakes, and eventually the ocean, affecting both freshwater and marine ecosystems.
The excess nutrients from fertilizers stimulate the growth of algae, leading to a phenomenon known as algal blooms or harmful algal blooms (HABs). These algal blooms can take over large areas of water, blocking light and depleting oxygen levels. As a result, fish and other aquatic organisms die, disrupting the food chain and causing what are known as dead zones. While dead zones occur naturally in some coastal areas, human activities have increased their frequency and duration, particularly in regions adjacent to densely populated areas.
In addition to fertilizers, chemicals from households, such as dish soaps, dishwasher detergents, and pesticides, also contribute to nutrient pollution. These chemicals contain phosphorus and other toxins that can be harmful to both human and marine life. When released into waterways, they can contaminate drinking water sources, making it unsafe for human consumption and detrimental to aquatic ecosystems.
To address the issue of fertilizer and chemical runoff, it is essential to implement sustainable practices. This includes promoting the efficient use of fertilizers, adopting eco-friendly alternatives, and creating "green infrastructure" to slow down and absorb polluted runoff. By working together and making conscious choices, we can help reduce the impact of fertilizer and chemical runoff on our precious beach ecosystems.

Littering and trash
Beach pollution is any harmful substance that contaminates coastlines, including trash, litter, sewage, pesticides, and oil. Trash and litter are considered any man-made solid material that ends up in the ocean, often referred to as "marine debris". Marine debris is a persistent pollution problem that affects beaches, coastal waters, estuaries, and oceans worldwide.
The accumulation of trash and litter on beaches and in the ocean has severe environmental and economic impacts. It can destroy marine life, close down coastal areas, and pose serious health risks to humans who come into contact with polluted water or sand. Marine animals may mistake debris for food, leading to ingestion of plastics and other harmful substances. Additionally, debris can form garbage patches in the ocean, pulled together by large rotating ocean currents called gyres. These garbage patches constantly change shape and size, affecting the ocean surface to the ocean floor.
To address the issue of littering and trash on beaches, it is crucial to take preventive measures and promote proper waste disposal. This includes reducing, reusing, and recycling waste, as well as properly disposing of trash and fishing equipment when visiting the beach. Beach clean-up events are also an effective way to remove trash and debris, with many local environmental groups, municipalities, and state agencies organizing such initiatives. During beach cleaning, it is important to prioritize the protection of wildlife and plants, such as sea turtle nesting areas, by using non-mechanized raking and litter removal methods.
