Beach pollution can cause illnesses and infections, especially for children, the elderly, and immunocompromised people
Beach pollution is a significant issue that poses risks to both environmental and human health. While swimming at polluted beaches, people can be exposed to harmful bacteria, viruses, protozoa, and parasites, leading to various illnesses and infections. Certain individuals, such as children, the elderly, and those with weakened immune systems, are more susceptible to the negative health impacts of beach pollution.
Water pollution at beaches can arise from various sources, including runoff from polluted stormwater, untreated sewage releases, and discharges from vessels. These discharges can contain trash, fishing gear, ballast water, and other contaminants. When rain or snowmelt exceeds the capacity of certain sewers, combined sewer overflows (CSOs) and sanitary sewer overflows (SSOs) can occur, releasing raw sewage, industrial wastewater, and stormwater into the environment, ultimately impacting beaches and coastal areas.
Swimming in polluted beach water can lead to several health issues. The most common illness associated with sewage-contaminated water is gastroenteritis, which can cause nausea, vomiting, stomachache, diarrhea, headache, or fever. Other minor illnesses linked to swimming in polluted water include ear, eye, nose, and throat infections. In rare cases, open wounds exposed to polluted water can also lead to infections. Additionally, the EPA has linked digging in polluted beach sand to an increased risk of gastrointestinal illness.
Children, the elderly, and immunocompromised individuals are particularly vulnerable to the health risks associated with beach pollution. Their developing or weakened immune systems make them more susceptible to infections and illnesses caused by pathogens in the water. While swimming-related illnesses are usually not severe and have no long-term health effects, they can be unpleasant and may require medical attention.
To minimize the health risks associated with beach pollution, it is essential to follow local advisories and avoid swimming at beaches with known pollution issues or after heavy rainfall. By being mindful of potential hazards and taking precautions, beachgoers can protect themselves and their loved ones from the negative health impacts of beach pollution, especially for those most vulnerable.

Sewage, trash, plastics, and other pollutants are common sources of beach pollution
Beach pollution is any harmful substance that contaminates coastlines, including plastic, trash, litter, sewage, pesticides, and oil. These pollutants can pose a serious health risk to people who come into contact with dirty water or sand. Sewage, trash, plastics, and other pollutants are common sources of beach pollution, which can have detrimental effects on both human and marine health.
Sewage is a significant contributor to beach pollution. Faulty or damaged water treatment systems can release untreated or partially treated sewage into water bodies, contaminating beaches. This contamination can lead to bacterial infections and illnesses in swimmers, with children being particularly vulnerable due to their tendency to swallow more water. According to the EPA, millions of people fall ill from exposure to sewage while swimming.
Trash and litter are also prevalent sources of beach pollution. Billions of pounds of trash end up in the ocean each year, with a significant amount washing up on beaches. This waste can come from a variety of sources, including improper disposal, stormwater runoff, and discharges from vessels such as recreational boats and commercial ships. Trash on beaches not only detracts from their natural beauty but also poses health risks to swimmers and beachgoers.
Plastics are another common pollutant on beaches. Plastic pollution has become a global issue due to increasing consumption and improper waste management. Plastics can enter the ocean through rivers and coastal activities, eventually washing up on beaches. Microplastics, in particular, are ingested by marine life, accumulating in the food chain and potentially reaching humans who consume seafood. The ingestion of plastic by marine animals can also lead to choking, internal injuries, or starvation, impacting the health and survival of various species.
Other pollutants contributing to beach pollution include pesticides, fertilizers, oil spills, and chemicals. These substances can enter the ocean through runoff from farms and livestock operations or as a result of human activities along coastlines. For example, excess nitrogen and phosphorus from fertilizers can act as pollutants, impacting the health of marine ecosystems and potentially affecting human health if contaminated water is ingested.
The presence of these pollutants on beaches highlights the importance of proper waste management, pollution prevention, and the protection and restoration of beach ecosystems. By addressing these common sources of beach pollution, we can mitigate health risks, preserve marine life, and ensure that beaches remain safe and enjoyable environments for all.

Beach sand can also be a source of pollution, increasing the risk of gastrointestinal illness
Beach pollution is any harmful substance that contaminates coastlines, including plastic, trash, litter, sewage, pesticides, and oil. It poses a serious health risk to people who come into contact with polluted water or sand. While swimming-related illnesses are usually not serious, children, the elderly, and immunocompromised individuals are most at risk of developing infections or illnesses.
The sand just above the high tide mark typically has the highest levels of faecal indicator organisms (FIOs) on tidally influenced beaches. Animal excreta, including that of dogs, birds, and other locally significant animals, increases FIO levels and introduces pathogens to beach sands. Operational monitoring of sand through visual inspections and potential sources of contamination is a cost-effective approach to verify sand quality.
In addition to animal waste, plastic pollution is also a significant issue. Plastic debris can end up on beaches, washed in with waves and tides. This plastic pollution not only affects marine life but can also impact humans. Plastic ingested by marine animals can move through the food chain, eventually reaching humans who consume seafood.

Climate change increases beach erosion and pollution from stormwater runoff and wastewater
Climate change is causing more frequent and intense storms and extreme flooding events, which increase stormwater runoff. This runoff can overwhelm municipal stormwater management systems, leading to backups and localized flooding. The increased volume of water can also cause greater runoff of contaminants such as trash, nutrients, sediment, bacteria, and chemicals into local waterways.
Beach erosion is a significant consequence of climate change, particularly in low-lying coastal areas. As sea levels rise, beaches are unable to provide protection for communities along coastlines, leaving residents vulnerable to extreme weather events. Beach erosion also destroys the unique habitats of sea animals, birds, and other species.
The impact of climate change on beach erosion and stormwater runoff contributes to the pollution of coastal environments. Pollution degrades the natural habitats of plants and animals, poses risks to public health, reduces property values, and inhibits economic growth in coastal communities.
Stormwater runoff, combined with wastewater from growing urban communities in coastal areas, further exacerbates pollution levels. This wastewater often contains a mixture of raw sewage, industrial waste, and stormwater. When the capacity of wastewater treatment systems is exceeded, untreated water is released into local streams and rivers, ultimately flowing into oceans and contaminating beach waters.
The combination of increased stormwater runoff and inadequate wastewater infrastructure poses a significant threat to beach health and human health. Polluted beach water can cause illnesses and infections, particularly in children, the elderly, and individuals with weakened immune systems. To protect public health and preserve the ecological integrity of beaches, it is essential to address the challenges posed by climate change and implement systemic changes to reduce pollution and improve wastewater management.

Pollution from boats and ships, including recreational and commercial vessels, is a significant contributor to beach pollution
Beach pollution poses a risk to public health, and pollution from boats and ships is a significant contributor. The shipping industry, including recreational and commercial vessels, is responsible for a large amount of pollutants being released into the ocean. This includes oil pollution, wastewater, solid waste, air pollution, noise pollution, and ballast water discharges.
Oil pollution from the shipping industry is a major concern. Cruise ships, which are much larger than other vessels, burn a significant amount of heavy fuel oil, which contains dangerous levels of sulfur and heavy metals. This oil can mix with oceanic water due to faulty engine systems, improper repair work, or collisions and accidents, leading to marine pollution. Additionally, small amounts of oil are leaked daily from millions of motor vehicle engines, eventually making their way into the ocean and contributing to beach pollution.
Wastewater and solid waste are also significant sources of pollution from ships and boats. Cruise ships produce a substantial amount of wastewater, including grey water from sinks, laundries, showers, and galleys. This wastewater is often dumped offshore, even after passing through treatment plants, which can impact the marine environment. Recreational vessels and commercial vessels are also responsible for discharging trash, fishing gear, and other solid waste into the ocean, which can wash up on beaches.
Air and noise pollution from ships and boats contribute to the degradation of the marine ecosystem. Cruise ships, in particular, have been found to have particulate matter pollution levels comparable to major cities. The noise produced by ships can disturb the marine ecosystem, especially affecting marine animals with sensitive hearing, such as killer whales and dolphins.
Ballast water discharges from large vessels, including cruise ships, can also impact beach pollution. As ships travel long distances, they fill and discharge ballast water, which can contain microbes, microorganisms, vegetation, and other sea animals. This can lead to ecological damage, such as the massive increase in jellyfish populations in the Black Sea.
The pollution from boats and ships can have direct and indirect impacts on human health. The discharge of pollutants into the ocean can contaminate beach water and sand, leading to illnesses or infections in swimmers, especially those with open wounds or those who ingest polluted water. Additionally, the pollution from vessels can degrade unique beach habitats needed by animals and plants, impacting the overall health of the ecosystem and the communities that depend on it.
