Beach pollution is caused by a variety of factors, including human activities, natural events, and climate change. The majority of pollutants that end up on beaches originate from human activities along coastlines and inland areas, such as littering, illegal dumping, poor waste disposal practices, and runoff from farms, vehicles, and industrial sites. Natural events like tsunamis, heavy rainfall, and snowmelt can also contribute to beach pollution by carrying pollutants from the land into the ocean and onto beaches. Climate change exacerbates the problem by increasing the frequency of extreme weather events, leading to more pollution being washed onto beaches. Sewage overflows, oil spills, and the accumulation of microplastics and marine debris further degrade the sensitive beach environment, posing risks to both human and marine life.

What You'll Learn
Land-based sources
Beach pollution is any harmful substance that contaminates coastlines, including plastic, trash, litter, sewage, pesticides, oil, and excess amounts of natural substances such as nitrogen and phosphorus from fertilizers and animal waste. The majority of beach pollution comes from land-based sources, with over 80% of marine pollution arising from human activities along coastlines and far inland.
One of the biggest sources of beach pollution is nonpoint source pollution, which occurs when rainfall or snowmelt carries pollutants from the ground into the ocean. This can include oil and other contaminants from roads, farms, and industrial sites. Nonpoint source pollution is often the result of runoff, which is when water flows over land, picking up pollutants such as bacteria-laden pet waste, animal manure, fertilizers, pesticides, chemicals, gasoline, motor oil, antifreeze, and soil/sediment. These pollutants can then be carried by rain into storm drains, streams, and rivers, eventually flowing into the ocean and washing up on beaches.
Another significant contributor to beach pollution is littering, illegal dumping, and poor waste disposal practices. Single-use plastic items such as bottles, utensils, and straws are major ocean polluters, as they are often not properly recycled or disposed of. Plastic waste can end up in landfills and oceans, where it can take hundreds of years to degrade, impacting marine life and the environment.
Manufacturing plants also contribute to beach pollution by releasing toxic waste, including mercury, into waterways. While sewage systems are designed to collect and treat sewage, unintentional discharges of raw sewage, known as sanitary sewer overflows (SSOs), can occur due to blockages, line breaks, or other issues. These overflows can contaminate waterways and beaches, posing health risks to both humans and marine life.
Additionally, extreme weather events caused by climate change can exacerbate beach pollution. More frequent storms and rising sea levels can carry more pollution to beaches, as stormwater runoff and wastewater from damaged infrastructure can contain various contaminants.

Vessels and boats
The impact of vessel and boat pollution on beaches is mitigated by regulations such as the Clean Boating Act, which covers recreational vessels, and the Vessel General Permit of the National Pollutant Discharge Elimination System permit program, which covers commercial vessels. These regulations aim to control the discharge of pollutants from different types of vessels. However, any trash that is not recycled or properly disposed of can eventually find its way to beaches through stormwater runoff, flowing into bays, estuaries, and oceans, and eventually washing up on shore.
In addition to the direct discharges from vessels and boats, beach pollution can also be caused by stormwater runoff carrying pollutants from land into the ocean. This includes oil and chemicals left on streets, as well as bacteria-laden pet waste, animal manure, fertilizers, pesticides, gasoline, motor oil, antifreeze, and soil or sediment. Climate change further exacerbates beach pollution by increasing the frequency of extreme weather events, which can damage infrastructure and release wastewater into the environment, contributing to beach erosion and pollution.
The pollution generated by vessels and boats has significant environmental and economic impacts on coastal communities. It degrades the unique beach habitats needed by animals and plants, posing a risk to public health and reducing property values. Additionally, it inhibits the economic growth of these communities by limiting the use of beaches for tourism, recreation, and aesthetic purposes. Therefore, it is crucial to address and mitigate the pollution caused by vessels and boats to protect the delicate balance of coastal ecosystems and ensure the well-being of the communities that depend on them.

Nonpoint source pollution
Beach pollution is caused by a variety of factors, one of the biggest being nonpoint source pollution. Nonpoint source pollution is challenging to control because it comes from multiple locations and sources. It is primarily caused by runoff, which occurs when rainfall or snowmelt moves over and through the ground, absorbing and carrying away natural and human-made pollutants. These pollutants are then deposited into lakes, rivers, wetlands, coastal waters, and groundwater.
Another example of nonpoint source pollution is fertilizer use in yards or farms. When excess fertilizer is applied, it can be washed away by rainwater and end up in nearby water bodies, contributing to pollution. Similarly, bacteria-laden pet waste, animal manure, pesticides, chemicals, gasoline, and motor oil can also be picked up by rainwater and contribute to nonpoint source pollution.
The impact of nonpoint source pollution on beaches can be significant. It can affect the quality of coastal waters, leading to closures of beaches to protect public health. It can also harm the sensitive beach environment, including plants and animals that depend on it. With high population densities along coastal regions, the pressure on the environment from nonpoint source pollution is even more pronounced.
Controlling nonpoint source pollution is a complex task due to its diverse sources and locations. However, it is crucial to address this issue to maintain the health of beaches and coastal ecosystems and to ensure they can be enjoyed for economic, recreational, and aesthetic purposes.

Point source pollution
Beach pollution refers to any harmful substance that contaminates coastlines, including plastic, trash, litter, sewage, pesticides, and oil. Point source pollution is pollution that comes from a single source, such as an oil or chemical spill, or discharge from faulty factories or water treatment systems. It is less common than non-point source pollution, which comes from many diffuse sources, but it often has a larger and more destructive impact.
One of the most significant contributors to point source pollution is industrial activity. Accidental or intentional discharges from factories and treatment plants can release harmful chemicals, raw sewage, and wastewater into nearby water bodies, leading to beach pollution. For example, combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs) can result in the release of untreated sewage, industrial wastewater, and stormwater into coastal areas. These overflows occur due to various factors, including blockages, line breaks, inadequate sewer design, and heavy precipitation, which can overwhelm the system.
Another source of point source pollution is maritime activities. Discharges from vessels, including trash, fishing gear, ballast water, bilge water, and sink or shower water, can directly contaminate beaches. The type of vessel determines the regulatory framework governing these discharges, with recreational vessels falling under the Clean Boating Act and commercial vessels under the Vessel General Permit and Coast Guard ballast water regulations.
Additionally, land-based human activities contribute to point source pollution. Littering, poor waste management practices, and illegal dumping directly introduce solid waste, plastic, and litter onto beaches and into the ocean. Furthermore, storm-related events, such as floods, can flush this waste into the sea, leading to beach pollution. Broken-down ships and discarded fishing gear also contribute to point source pollution, damaging sensitive habitats and endangering marine life.
While less frequent than non-point source pollution, point source pollution events can have significant impacts on beach ecosystems and public health. Polluted beaches pose serious health risks to individuals who come into contact with contaminated water or sand. The EPA estimates that up to 3.5 million people fall ill from exposure to sewage while swimming, with children being particularly vulnerable due to their tendency to swallow more water.

Climate change
The combination of rising sea levels and more frequent storms causes tidal flooding, further exacerbating the problem. Communities like Boston, Houston, and Orlando have witnessed a doubling in the number of tidal flooding days annually over the last two decades. This flooding has severe consequences for coastal ecosystems, disrupting the habitats of many wildlife species. For example, the saltmarsh sparrow population on the East Coast is declining due to increased flooding from rising sea levels and more extreme storms.
The impacts of climate change extend beyond environmental degradation, affecting communities that depend on beaches for tourism, fishing, and other industries. A polluted beach poses a public health risk, reduces property values, and hinders the economic growth of these communities. Additionally, beaches that undergo erosion due to climate change can no longer provide adequate protection for nearby communities and habitats, making them more vulnerable to flooding and storms.
To address these challenges, organizations like the US EPA are working on initiatives such as Climate Ready Estuaries to help coastal managers and communities adapt to the changing environment. By improving the resilience of beaches and estuaries, we can mitigate the impacts of climate change and preserve the health of these vital ecosystems.
