Florida's Water Pollution: Causes And Concerns

Florida has a long history of water pollution problems, with many of its waterways failing to meet water quality standards. Nutrient pollution, caused by excess nitrogen and phosphorus, is one of the state's biggest issues. This can come from various sources, including untreated sewage, leaking septic tanks, inadequately treated wastewater, and stormwater runoff carrying fertilizers and pesticides. Other factors contributing to water pollution in Florida include industrial activities, agricultural runoff, and increasing development in urban and rural areas. The state's aging and poorly maintained wastewater infrastructure has also resulted in sewage spills, further exacerbating the problem. Additionally, Florida faces the issue of forever chemicals or PFAS, in its drinking water, affecting millions of residents.

Sewage failures

Florida has a long history of water pollution problems caused by sewage failures. The state's wastewater infrastructure is failing due to old age, poor maintenance, increased populations, and rising sea levels in already low-lying communities. This has resulted in over 1.6 billion gallons of sewage spilling into local communities and waterways between 2015 and 2020, posing a significant risk to human health and devastating Florida's waterways and coastal ecosystems.

One of the main issues with sewage failures in Florida is the inadequate treatment of wastewater. Many homes in Florida are connected to septic systems that do not adequately treat wastewater, leading to nutrient pollution in the form of excess nitrogen and phosphorus. This excess of nutrients causes harmful algae blooms, which suffocate aquatic life and can cause respiratory issues for beachgoers. In addition, the bacteria and pathogens in sewage can cause infections and even death for humans or pets exposed to it.

Another issue is the lack of proactive maintenance of wastewater systems by city and county officials. In some cases, officials have even been accused of downplaying the significance of sewage pollution, undermining public trust in their ability to address long-term problems. For example, in St. Pete, one of the four sewage treatment plants was closed in 2015, leading to massive sewage spills into local waters. Despite knowing about the issue, city officials failed to provide adequate disclosures about the scope and impact of the pollution.

Furthermore, Florida's sewage infrastructure is struggling to keep up with the state's growing population and rising sea levels. The increased demand on the system, combined with outdated infrastructure, has led to frequent sewage spills. In addition, the state's environmental agency has been criticized for not effectively enforcing applicable laws and holding negligent officials accountable. This has resulted in a lack of incentive for city and county officials to improve their wastewater management practices.

To address the issue of sewage failures in Florida, there have been calls for increased funding for programs such as the EPA's BEACH Act Grants Program and the Clean Water State Revolving Program. These programs aim to support water quality testing and invest in repairing and upgrading wastewater infrastructure. By addressing the underlying issues of ageing infrastructure and inadequate maintenance, Florida can work towards reducing sewage spills and improving water quality for its residents and tourists.

Stormwater runoff

The Conservancy of Southwest Florida advocates for improved stormwater management, treatment, and regulations to safeguard the region's water resources from untreated stormwater runoff. They recommend that new and existing developments be required to implement adequate stormwater treatment mechanisms to prevent the exacerbation of current water quality issues or the creation of new ones. At the state level, the Conservancy has participated in updating statewide stormwater rules, which several cities and counties have already implemented.

Inadequate stormwater management, such as insufficient retention and treatment of stormwater on-site, has detrimental effects on water quality in southwest Florida. To address this, the Conservancy suggests adopting protective local stormwater and fertilizer ordinances. County and city governments should implement stringent regulations to limit the adverse effects of stormwater and fertilizers on waterways. Additionally, effective source control, protective and enforceable water quality standards, and adherence to TMDLs (Total Maximum Daily Loads) and implementation of BMAPs (Basin Management Action Plans) are recommended to protect and restore water quality.

While industrial plants and large farms are often perceived as the primary sources of pollution, residents, businesses, and visitors also contribute to excess nutrients and pollutants in South Florida's water bodies. Individual actions, such as properly maintaining local stormwater management systems and using fertilizers, herbicides, and pesticides with care, can significantly reduce stormwater pollution. Being mindful of how easily household chemicals and other pollutants can enter ground and surface water systems is crucial for preserving clean water in Florida.

Red tide

Florida's high annual rainfall, averaging 55-60 inches, contributes to the issue. When rain falls, excess stormwater is channelled into communities' stormwater collection systems, ponds, lakes, or canals. Along the way, this stormwater runoff can pick up pollutants such as fertilisers, pesticides, oils, and coolants, which then flow into lakes, rivers, and wetlands, eventually reaching the groundwater aquifers that supply drinking water.

To address the issue of red tide, it is important to focus on controlling pollution at its source. This involves adequately treating water onsite to prevent pollution from entering water bodies. Additionally, protective and enforceable water quality standards, as well as local stormwater and fertiliser ordinances, are crucial.

To protect themselves during red tide events, beachgoers can utilise resources such as the Red Tide Respiratory Forecast, which provides irritation risk levels projected over 24 hours, and the Beach Conditions Reporting System by Mote Marine Laboratory, which offers condition reports for beaches and coastal recreation areas.

Nutrient pollution

In Florida, phosphorus is abundant, primarily found in sedimentary rock and natural soil. While the Greater Everglades ecosystem thrives on low phosphorus levels, agricultural and urban development has introduced higher levels of nutrients, particularly phosphorus, into the environment. This has led to the excessive growth of certain plant species, such as cattails, which crowd out native plants favoured by wildlife.

Excess phosphorus in surface waters also contributes to the growth of algae and duckweed. Sources of nutrient pollution include agricultural and urban runoff, inadequately treated sewage, leaking septic tanks, and stormwater runoff carrying fertilizers and pesticides. Florida's high rainfall, averaging 55-60 inches per year, can exacerbate this issue as stormwater collection systems can become overwhelmed, allowing pollutants to enter waterbodies.

To address nutrient pollution, it is essential to control pollution at its source. This includes effectively treating water on-site, implementing protective water quality standards, and adopting local ordinances to limit the negative impacts of stormwater and fertilizers on waterways. Additionally, managing landscapes through proper plant selection and maintenance can help reduce pollutants flowing into surface and groundwater systems.

Overall, nutrient pollution poses a significant threat to Florida's water quality and ecosystems, and addressing it requires a combination of source control, improved wastewater treatment, and responsible land management practices.

Industrial and agricultural sources

Florida has a long history of water pollution problems caused by industrial and agricultural sources. The state's wastewater infrastructure is failing due to old age, poor maintenance, increased populations, and rising sea levels in already low-lying communities. This has resulted in billions of gallons of sewage being spilled into local communities and waterways, causing toxic algae blooms, fish kills, and coral reef die-offs.

Agricultural development in South Florida adds high levels of nutrients, such as phosphorus, to the landscape. This leads to excessive vegetation growth, including cattails, which crowd out native plants favoured by wildlife. Higher phosphorus concentrations in surface waters also contribute to the growth of organisms like algae and duckweed.

Industrial activities, such as mining and oil drilling, also play a role in water pollution. Inadequate stormwater management in these sectors can lead to untreated stormwater runoff, which can carry pollutants such as fertilizers and pesticides into local water bodies.

To address these issues, the Conservancy of Southwest Florida advocates for better stormwater management, treatment, and regulations. They recommend that new and existing developments utilize sufficient mechanisms for stormwater treatment to prevent further water quality deterioration.

Additionally, individuals and small businesses can contribute by properly maintaining local stormwater management systems and using fertilizers, herbicides, and pesticides with care. Managing landscapes effectively can also help reduce pollutants flowing into surface and groundwater systems.
