What You'll Learn
Unsafe levels of bacteria
Florida's beaches are often recognised for their stunning nature and beauty. However, reports have shown that several beaches in the state have been plagued with severe pollution for decades. In 2020, it was reported that the majority of Florida's beaches had unsafe levels of pollution, putting swimmers at risk.
The primary concern regarding pollution on Florida's beaches is the presence of unsafe levels of bacteria, specifically fecal bacteria. According to a 2024 report, 70% of Florida's beaches were found to have unsafe levels of fecal bacteria. This is a significant increase from previous years, as a 2023 report by the Surfrider Foundation identified only two Florida beaches among the most polluted in the United States.
Fecal bacteria can come from stormwater runoff, pets, wildlife, and human sewage. If ingested or if it comes into contact with open wounds, it can cause gastrointestinal illnesses, infections, and rashes. The presence of unsafe levels of fecal bacteria in the water is a serious health risk for swimmers and can lead to diseases and other negative health consequences.
To address this issue, Florida has implemented various measures, including water testing and monitoring programs. The Beach Water Sampling Program, established in 2000 and extended in 2002 with additional funding from the U.S. Environmental Protection Agency, collects water samples from Florida's coastal counties to test for fecal coliform and enterococci bacteria. The Florida Department of Health also routinely monitors fecal indicator bacteria and posts the results and advisories on their Healthy Beaches website.
Despite these efforts, the problem of unsafe bacteria levels on Florida's beaches persists. This is partly due to the lack of comprehensive testing, as the number of beaches tested varies across counties. Additionally, funding changes in 2011 led to a reduction in sampling locations and the suspension of sampling in the northern parts of the state during the winter months.
To protect themselves, individuals are advised to check for swim advisories on the Florida Department of Health's website before visiting the beach. However, ultimately, the solution lies in stopping beach pollution at its source, such as by repairing sewage systems and preventing runoff pollution.

Fecal pollution
The primary sources of fecal pollution on Florida's beaches include sewage overflows, stormwater runoff, and decaying infrastructure. Sewage overflows, often caused by heavy rains or outdated sewage systems, can lead to the discharge of untreated sewage into coastal waters. Stormwater runoff, which occurs when rainwater washes pollutants from roads, parking lots, and other hard surfaces into nearby water bodies, can also carry bacteria, chemicals, and other contaminants onto beaches. Additionally, Florida's aging infrastructure, including outdated sewage systems, contributes to the problem by increasing the likelihood of sewage overflows and other forms of pollution.
The presence of fecal indicator bacteria, such as enterococci and fecal coliform, serves as a critical marker for assessing fecal pollution. These bacteria are typically found in the intestinal tracts of humans and animals, and their detection in high concentrations suggests potential health risks for beachgoers. Ingesting contaminated water or having it come into contact with open wounds can lead to gastrointestinal illnesses, infections, rashes, and other diseases.
To address the issue of fecal pollution, experts recommend a range of measures. On an individual level, simple actions such as picking up pet waste and properly disposing of trash can help reduce the risk of fecal contamination. However, addressing the problem on a larger scale requires significant changes in infrastructure. Investing in green infrastructure to protect and restore natural landscapes can help absorb stormwater before it reaches the beaches. Additionally, updating sewage infrastructure and modernizing wastewater systems are crucial steps in mitigating sewage overflows and improving water quality.
While Florida's Healthy Beaches Program routinely monitors fecal indicator bacteria and issues advisories as needed, further efforts are necessary to reduce the prevalence of fecal pollution on the state's beaches. By implementing the recommended measures and investing in infrastructure improvements, Florida can better protect the health of its residents and visitors who enjoy its beautiful beaches.

Harmful Algae Blooms
Florida is known for its beaches and estuaries on both coasts, as well as its thousands of miles of rivers, lakes, and springs. The state's vast salt and freshwater resources also support populations of bloom-forming algae. While most of these algae are beneficial and form the foundation of the aquatic food web, dozens of species can form algal blooms—a rapid and substantial increase in algal biomass. Some of these blooms can become harmful by producing toxins or causing other negative impacts on the environment and aquatic ecosystems. These blooms are called harmful algal blooms (HABs).
HABs usually occur in summer or early fall and can affect small and large areas of a water body. They can move around and change within a water body due to tides, winds, and naturally fluctuating amounts of algae. While a specific location may not have a constant bloom, the bloom itself can continue for weeks, months, or over a year. As some HABs decay, they release a bad odor due to hydrogen sulfide, a foul-smelling gas that is a naturally occurring and colorless decomposition product. Although it is not harmful to health, the smell can cause respiratory irritation.
Florida has one of the country's most robust monitoring and reporting programs for marine and freshwater HABs. Residents and visitors can use these resources to learn about the current status of HABs in Florida. NOAA issues HAB bulletins that contain analyses of ocean color satellite imagery, field observations, models, public health reports, and buoy data. These bulletins are made available to the public a week after they are issued.
Florida's coastal economies depend on tourism and marine-dependent industries that rely on healthy water bodies. Effective communication about the presence of HABs is essential to achieving the balance needed for public safety and protecting the local economy.

Stormwater runoff
The stormwater collects various pollutants along its path, including debris, dirt, and chemicals. This can include plastic bags, bottles, cigarette butts, insecticides, herbicides, paint, motor oil, and heavy metals. These pollutants can contaminate drinking water supplies and harm aquatic life. Stormwater runoff is a type of non-point source pollution, which means that it cannot be traced back to a single source but rather originates from multiple sources throughout the environment.
In the context of Florida's beaches, stormwater runoff can carry enteric bacteria, such as enterococci, which are indicators of fecal pollution. These bacteria can cause gastrointestinal illnesses, infections, or rashes if ingested or if they come into contact with skin through cuts or sores. The presence of these bacteria in recreational waters is a health concern for swimmers and can lead to beach closures.
To address the issue of stormwater runoff, Florida has implemented programs such as the Florida Healthy Beaches Program, administered by the Florida Department of Health. This program involves routine sampling of beach water to detect bacteria and providing information to protect the health of residents and visitors. Additionally, Florida monitors water quality and takes appropriate measures to mitigate pollution and protect public health.
While stormwater runoff is a significant contributor to pollution on Florida's beaches, it is not the only source. Other factors, such as sewage spills, wildlife, and human activity, also play a role in the overall pollution levels.

Plastic pollution
Florida's beaches and waterways are not immune to this global issue. Plastic pollution is a significant threat to Florida's marine life, with microplastics and larger plastic items causing harm to animals through ingestion and entanglement. Sea turtles, birds, fish, manatees, and other marine organisms are all affected by plastic pollution in Florida's waters. The impact of plastic pollution on Florida's marine life is evident in the increasing number of stranded and injured animals found along the state's coastline.
One of the significant contributors to plastic pollution in Florida's beaches and oceans is littering. The improper disposal of plastic items such as food wrappings, plastic bags, bottles, and straws leads to their eventual entry into waterways and the ocean. Coastal cleanups and river sweeps are essential in tackling this issue, and Florida volunteers have made significant efforts over the past three decades, collecting hundreds of thousands of plastic items.
Another source of plastic pollution in Florida's waters is industrial fishing. Abandoned fishing gear, such as nets and six-pack rings, can entangle marine wildlife, leading to drowning or severe injuries. Additionally, microplastics, which are tiny particles of plastic, are easily ingested by marine animals in Florida, causing health issues and even death. These microplastics can come from the breakdown of larger plastics or the shedding of microfibers from synthetic clothing.
The problem of plastic pollution in Florida's beaches and oceans is not just an environmental issue but also an economic one. The economic costs of plastic pollution in the ocean are estimated to be between $6-19 billion USD annually, impacting tourism, fisheries, and aquaculture. As a top tourist destination, Florida's brand and economy are closely tied to the health and cleanliness of its beaches and waterways.
Addressing plastic pollution in Florida requires a two-pronged approach. Firstly, it is crucial to prevent plastic pollution from entering waterways and beaches by promoting proper waste disposal and reducing the use of single-use plastics. Secondly, ongoing coastal cleanups and initiatives, such as pellet patrols, are necessary to remove existing plastic pollution and protect Florida's environmentally sensitive areas and wildlife.
