What You'll Learn
Sources of pollution
Mobile Bay is the fourth-largest drainage basin in North America by volume. As such, it is vulnerable to a variety of pollutants, including runoff pollution, wastewater, and pathogens.
Runoff Pollution
The waterways that flow into Mobile Bay carry runoff pollution from as far away as another state, as well as from local neighbourhoods. Sources of this pollution include failing septic systems, ageing municipal infrastructure, and overboard dumping.
Wastewater
Wastewater is another source of pollution in Mobile Bay. The Three Mile Creek Watershed Management Plan, published in September 2014, describes the ecological challenges related to stormwater and wastewater as sources of pathogen pollution. The Creek was added to the States' list of impaired water bodies for pathogen exceedances, with municipal and storm sewers indicated as sources.
Pathogens
Pathogens are a particular concern in Mobile Bay, especially along the northern shore of Mississippi Sound, which is favoured for oyster aquaculture operations. Fecal coliform bacteria, for example, often exceed the shellfish harvesting criteria, leading to restrictions on shellfish harvesting in certain areas. Investigations into the sources of bacterial pathogens have indicated that human activities, such as untreated sewage from failing septic tanks, are likely contributing to the issue.
Air Pollution
While the focus has been on water pollution, air pollution is also a concern for Mobile Bay. Air pollution can be carried by wind and weather over long distances, eventually falling onto land or water. Sources of air pollution in the Chesapeake Bay region, for example, include stationary sources (power plants, manufacturing facilities), mobile sources (cars, trucks, boats), agricultural sources (farm operations), and natural sources (lightning, dust storms).

Environmental impact
Mobile Bay is the fourth-largest drainage basin by volume in North America. It receives 43 billion gallons of water per day, which flow from the Appalachians and the Rockies into the Gulf of Mexico via the Mississippi and Mobile Bay drainage basins. The Mobile Bay Basin is one of the richest natural resources in the United States, with a diverse range of flora and fauna. It is home to hundreds of species of fish, crayfish, mussels, snails, and other aquatic life forms, many of which are unique to the region.
However, the bay has been facing environmental issues due to rampant mismanagement of water resources and pollution. In 2016, Alabama's mismanagement of water resources resulted in new record-low streamflows in over ten percent of the watershed's streams due to unchecked water consumption and a lack of action on water shortages. The Mobile Bay and its surrounding waterways are also affected by wastewater pollution, which can threaten human health and damage ecosystems. Ken Heck, a senior marine scientist, estimates that half of the grass beds in Mobile Bay and coastal Alabama have disappeared due to murky waters, threatening the nursery grounds for shrimp, crabs, fish, and other wildlife.
Sewage overflow is a significant issue, with 26 million gallons entering the bay in 2017 from spills in Mobile and Baldwin counties. Failing septic systems, used by a quarter of Americans, also contribute to water pollution, with a failure rate of 5-35%. The city of Fairhope has been criticized for having the dirtiest beach in Alabama, with high levels of fecal bacteria in the water.
Despite these challenges, there are success stories, such as Tampa Bay, which has made significant strides in improving water quality through seagrass restoration. Conservationists emphasize the need to focus on solutions and learn from past mistakes to protect Mobile Bay for future generations.

Water quality
Mobile Bay is the fourth-largest drainage basin in North America by volume. Nearly two-thirds of Alabama's water drains into the bay, which is part of the second-largest river delta system in the United States. The bay receives 43 billion gallons of water per day, which carries runoff pollution from as far as a state away. The sources of this pollution include failing septic systems, illicit discharges, and stormwater.
In 2019, an environmental think tank report listed Fairhope Public Beach, which juts out into Mobile Bay, as the dirtiest beach in Alabama. The report found that the beach had 21 days where the amount of fecal bacteria in the water exceeded the Environmental Protection Agency's recommended threshold. In response, the city of Fairhope acknowledged the water quality issues and highlighted their efforts to address wastewater collection, transmission, and treatment.
The Mobile Bay Basin is recognized as one of the richest natural resources in the United States, known for its biological diversity and unique natural heritage. However, it faces threats due to rampant mismanagement of water resources, with river flows being altered to accommodate excessive use and consumption. Alabama, which is responsible for most of the watershed, has been criticized for its failure to address water shortages and manage water usage effectively.
The health and safety of Mobile Bay have been a concern for residents and environmental advocates. While there are rumors of dirty and unhealthy waters, the available data does not support the claim that the bay is unsafe for swimming or fishing. However, there are legitimate environmental issues, such as sewage overflow and nutrient pollution, that need to be addressed. Ken Heck, a senior marine scientist, estimates that half of the grass beds in Mobile Bay and coastal Alabama have disappeared due to murky waters, threatening the ecosystem and the species that depend on it.

Health and safety
Mobile Bay is a biologically rich natural resource, home to hundreds of species of fish, birds, alligators, manatees, mussels, crayfish, snails, and other aquatic lifeforms. However, the bay has faced environmental issues due to pollution from the rivers that flow into it. This has led to concerns about the health and safety of those who utilize the bay for recreation, fishing, and swimming.
One of the primary concerns is the presence of bacteria in the water, such as Vibrio vulnificus, which can cause vibriosis, a potentially serious infection. While the risk of severe illness from Vibrio is generally low, it can be higher for individuals with weakened immune systems or certain underlying conditions. To address this concern, regular sampling and monitoring for bacteria, such as enterococci, are conducted to determine the safety of the waters for swimming.
Additionally, wastewater pollution, resulting from agricultural, industrial, and domestic activities, poses a threat to both human health and ecosystems. Sewage overflow has been a significant issue, with 26 million gallons of sewage spilling into Mobile Bay in 2017. This has contributed to the degradation of grass beds, which serve as a vital habitat for various species.
The mismanagement of water resources has also exacerbated the problem. River flows have been altered to accommodate excessive consumption, leading to record-low stream flows in Alabama in 2016. Furthermore, failing septic systems, used by a significant portion of the population, contribute to water pollution and negatively impact water quality.
While there are legitimate environmental concerns, some media outlets and local sources may have sensationalized the risks, spreading misinformation about the safety of swimming and fishing in Mobile Bay. It is important to rely on scientific data and facts when assessing the health and safety of the bay. Local governments and citizens play a crucial role in staying informed and proactive in implementing solutions to address pollution and improve water quality.
