Galveston Beach in Texas has received a bad rap over the years for being dirty and crowded. However, recent reports and testimonies from locals indicate that the beach is not as polluted as people say it is. The Galveston County Health District (GCHD) routinely tests 52 beach sites for bacterial indicators, particularly enterococcus, which is common in rain runoff and often spikes after heavy rainfall. While advisories are issued when enterococcus levels exceed the safe limit, these advisories are informational tools and do not lead to beach closures. While bacteria are naturally present in the water, pollution from sources like failing septic systems, pet waste, livestock, and boats with onboard toilets can contribute to higher concentrations.

What You'll Learn
Fecal contamination and bacterial indicators
Galveston's beach water is tested for bacterial indicators, specifically enterococcus, which is a valuable indicator for determining the presence of fecal contamination. Enterococcus is a bacteria found in the intestines and waste of all mammals, including humans.
Fecal contamination of beach water is a concern in Galveston, and it is not a new issue. In 2022, 61 Texas beaches were tested for fecal indicator bacteria, and 90% of beaches recorded potentially unsafe levels of fecal contamination for at least one day. These findings indicate that the water at most Texas beaches exceeded the Environmental Protection Agency's (EPA) enterococcus "Beach Action Value," which is used to issue advisories and protect people from swimming in potentially unsafe waters.
Fecal bacteria can enter Galveston Bay through various sources, including failing septic systems, pet waste, livestock, and boats with toilets or "heads" onboard. Rainfall can also contribute to spikes in bacteria concentrations as runoff carries bacteria into the Bay. This is particularly true after heavy rain or storms, when bacteria levels often spike due to increased runoff from streets, lawns, and infrastructure malfunctions.
The presence of fecal bacteria in the water can lead to health issues for swimmers. Exposure to high levels of enterococcus can cause illnesses such as gastrointestinal problems, nausea, vomiting, diarrhea, stomachaches, headaches, fever, and skin and soft tissue infections. It can also lead to eye, ear, and respiratory infections. While these illnesses are generally short-lived and easily treated, children, the elderly, and individuals with weakened immune systems are more vulnerable to developing these illnesses after swimming in contaminated water.
To protect public health, the Galveston County Health District (GCHD) routinely tests 52 beach sites for bacterial indicators. When a sample shows high levels of enterococcus, an advisory is issued for the corresponding beach, indicating that swimming is not recommended. These advisories are indicated with signs on the beach and online, but the beach remains open.

Human and animal waste runoff
There are several factors that contribute to the presence of human and animal waste in the waters of Galveston beach. Firstly, rain frequently washes animal and human waste into waterways that eventually flow into the Gulf of Mexico, causing a spike in enterococcus levels. This is particularly common after heavy rainfall or storms, when runoff carries bacteria into the bay from various land sources, such as failing septic systems, pet waste, and livestock. Additionally, boats with toilets or heads on board can also contribute to the bacteria contamination, as even "treated" waste contains high levels of faecal bacteria.
The presence of human and animal waste in the water poses a risk to human health. Exposure to faecal bacteria can cause various illnesses, including gastrointestinal problems such as nausea, vomiting, diarrhoea, stomachache, and headaches. It can also lead to skin and soft tissue infections, eye and ear infections, and respiratory issues. While these illnesses are generally short-lived and easily treated, they can be more severe in children, the elderly, and individuals with weakened immune systems. Additionally, high concentrations of bacteria and associated pathogens can accumulate in oysters and other shellfish, making them unsafe to eat, especially if consumed raw.
To address the issue of human and animal waste runoff, the Galveston County Health District (GCHD) participates in the Texas Beach Watch program, which tests for enterococcus levels at 52 beach sites in Galveston County throughout the year. When levels of enterococcus exceed the safe standard, an advisory is issued for the beach, although it remains open. The GCHD also provides advice to local residents on how to improve water quality through the Galveston Bay Report Card, encouraging the implementation of more efficient lawn irrigation, the use of rain barrels, and the installation of green infrastructure to reduce runoff and pollution.

Advisories, warnings, and health risks
Galveston Beach in Texas has been the subject of several reports and news articles concerning water pollution and health risks. The beach is routinely monitored by the Galveston County Health District (GCHD) as part of the Texas Beach Watch program, which tests for bacterial indicators, particularly Enterococcus, to ensure safe swimming conditions.
The presence of bacteria in the water is a primary concern for swimmers and visitors to Galveston Beach. Enterococcus bacteria are naturally found in the intestines of mammals and birds, and their presence in high concentrations indicates faecal contamination. After heavy rainfall, bacteria levels tend to spike due to runoff from various sources, including failing septic systems, pet waste, livestock, and boats with onboard toilets. This runoff eventually flows into the Gulf of Mexico, causing a temporary increase in bacterial levels.
When Enterococcus levels exceed the EPA standard for safe swimming, an advisory is issued for the beach. These advisories are indicated by signs at the beach and online. While the beach remains open during an advisory, swimmers are advised to avoid entering the water if they have open wounds or intend to ingest it. This is because exposure to polluted water can cause gastrointestinal illnesses, with symptoms including nausea, vomiting, diarrhoea, stomachache, headache, fever, and infections on open wounds. Children, the elderly, and individuals with weakened immune systems are particularly vulnerable to these illnesses.
In addition to Enterococcus, Galveston Beach has been associated with the presence of Vibrio vulnificus, a type of "flesh-eating" bacteria. While not unique to Galveston, this bacteria can cause severe skin and soft tissue infections and, in some cases, bloodstream infections in individuals with underlying health issues. It is important to note that Vibrio vulnificus is not related to pollution and is naturally present in warm saltwater worldwide.
Other health risks at Galveston Beach include the presence of tar from oil deposits, dead fish due to asphyxiation in hot water, rip currents, and the potential to step on stingrays. Additionally, large areas of Galveston Bay are closed for harvesting shellfish due to elevated bacterial concentrations, making them unsafe for human consumption, especially when raw.
To ensure a safe beach experience, visitors are advised to check for advisory signs, avoid swimming with open wounds, and refrain from ingesting seawater. Additionally, staying informed about the latest water quality reports and bacteria concentrations can help visitors make informed decisions before entering the water.

High levels of litter and pollution can lead to beach closures and restrictions, impacting the local economy, which is heavily dependent on tourism.
One of the significant issues affecting Galveston Beach is bacterial pollution, particularly enterococcus, which is a type of bacteria that indicates the presence of fecal contamination. This bacteria is naturally found in the intestines of mammals and birds and can enter the water through rainwater runoff, sewage overflows, and other sources. While most healthy adults are unlikely to become ill from ingesting water with high levels of enterococcus, it can cause gastrointestinal illnesses, especially in children, the elderly, and those with weakened immune systems.
To address the issue of bacterial pollution, the Galveston County Health District (GCHD) actively participates in the Texas Beach Watch program, which routinely tests 52 beach sites in Galveston County for enterococcus. When levels of this bacteria exceed the safe limit, an advisory is issued for the beach, although the beach remains open. Advisories typically last for 48 hours, and during this time, the site is tested daily until the bacterial levels decrease.
In addition to bacterial pollution, Galveston Beach also faces issues with other types of litter and pollution. For example, small items like cigarette butts, bottle caps, and plastic litter the beach, posing a threat to wildlife and the environment. To combat this, beach technicians like Freda Johnson work to pick up litter, and local organizations provide advice and resources to reduce pollution and improve water quality.
Overall, while Galveston Beach faces challenges with cleanliness and litter, there are ongoing efforts to improve the situation. Through routine testing, advisory systems, and local initiatives, Galveston Beach strives to maintain a safe and enjoyable environment for both visitors and the local ecosystem.
