What You'll Learn
Industrial waste and fertilizer runoff
Texas is ranked as the biggest emitter of toxic substances into its waterways in the United States. The state's waterways are easily accessible for industrial projects with large amounts of liquid waste. In 2020, Texas saw 16.7 million pounds of toxic substances released into its waters, a notable increase from 13.2 million pounds in 2007.
Nitrate compounds, which are commonly found in fertilizer runoff and industrial waste, account for up to 90% of total toxic releases reported by industries across the country. These compounds have severe ecological and health impacts, as they eventually make their way from lakes and rivers into drinking water and breast milk.
Fertilizer use in Texas is prevalent in the agricultural sector, particularly in crop production and livestock grazing. Excess fertilizers from fields can be washed off by rainwater, leading to fertilizer runoff that contaminates nearby water bodies. This runoff contains high levels of nitrogen and phosphorus, which can cause excessive algae growth in water, leading to oxygen depletion and the creation of "dead zones" where aquatic life cannot survive.
Industrial waste is another significant contributor to water pollution in Texas. The state is home to numerous refineries and chemical plants, as well as a thriving energy sector. These industries generate large volumes of wastewater and chemical by-products that require proper treatment and disposal. However, Texas's regulatory environment has been described as lax, making it challenging to enforce fines for violations. Companies often find it more cost-effective to pay fines rather than invest in pollution prevention.
To address these issues, Texas has established the Texas Commission on Environmental Quality (TCEQ), which is responsible for managing and controlling water pollution. The TCEQ processes numerous permit applications for industrial wastewater discharge, ensuring compliance with established standards. However, there is a lack of transparency regarding the specific toxic components released by industries.

Poultry and meat processing plants
Texas is ranked as the number one state for water pollution in the US, with poultry and meat processing plants being major contributors. The state's waterways are the fourth most polluted in the nation, with companies releasing around 14.6 million pounds of industrial pollutants and toxic chemicals into Texas' waterways in 2010.
The Environmental Protection Agency (EPA) has identified meat and poultry product (MPP) plants as a major source of water pollution in Texas and has proposed new rules to limit water pollution from these facilities. Nitrate compounds, a common component of fertilizer runoff and industrial waste, account for a significant proportion of the pollutants discharged by these plants. The EPA's proposals include revised nitrogen limits and new pretreatment standards for certain pollutants, which are expected to reduce national nitrogen pollution.
The Texas Commission on Environmental Quality (TCEQ) oversees programs to manage and control water pollution in the state, including permitting, water monitoring, and compliance enforcement. However, there have been calls for stronger water pollution control permits and better enforcement to stop the contamination of Texas' waterways. Environmental groups have argued for stricter regulation of chicken-growing operations, which are currently considered nonpoint sources of pollution and are not subject to stricter permitting requirements.
The growth of the poultry industry in Texas has raised concerns about the potential increase in pollution. Processing plants release millions of gallons of wastewater and manure into streams and creeks, which can upset the delicate balance of nutrients in waterways, leading to excessive algae growth and harming aquatic life.

Chemical plants and refineries
Texas has been ranked as the nation's biggest emitter of toxic substances into its waterways. The state's waterways are easily accessible for industrial projects with large volumes of liquid waste. In 2020, Texas ranked first among U.S. states for toxic discharges into streams, rivers, and lakes, with 16.7 million pounds of toxic substances released into Texas waters, up from 13.2 million in 2007.
For example, in 2020, Pilgrim's Pride, a chicken production company, released 2.7 million pounds of nitrate compounds into Tankersley Creek, which flows into Lake O' the Pines. Additionally, two Valero refineries near Galveston Bay in Houston and Texas City were the second and third top polluters, respectively, releasing a collective 3.2 million pounds of water pollution, including hydrogen cyanide and acrylonitrile.
The Texas Commission on Environmental Quality (TCEQ) is responsible for overseeing programs to ensure the safe management of pollutants in Texas surface waters. However, TCEQ has been criticized for its lax enforcement of pollution regulations, with industrial facilities exceeding pollution limits without facing significant consequences.
To address water pollution from chemical plants and refineries, TCEQ implements programs such as the Total Maximum Daily Load (TMDL) Program, which aims to improve impaired surface waters by reducing pollution. Additionally, the Nonpoint Source Program focuses on preventing and mitigating pollution caused by the runoff of small amounts of pollutants from numerous sources.

Plastic pellets and PFAS chemicals
Texas has been ranked as the state with the highest level of toxic substances discharged into its streams, rivers, and lakes. The state's waterways are polluted with a variety of contaminants, including plastic pellets and PFAS chemicals, which have severe environmental and health impacts.
Plastic pellets, also known as "nurdles," are tiny plastic particles that serve as raw materials for various plastic products. These pellets have been released into Texas waterways, particularly in areas near plastic manufacturing plants such as Lavaca Bay. The release of plastic pellets has been a persistent issue, with millions of pellets found in the bays and creeks near Point Comfort, impacting fish and other marine life. Environmental advocates like Diane Wilson have worked to raise awareness and hold companies accountable for their pollution.
PFAS (per- and polyfluoroalkyl substances), also referred to as "forever chemicals", are synthetic compounds with unique properties that repel oil and water and resist heat. PFAS have been widely used in consumer products since the 1940s, including nonstick cookware, waterproof mascara, soaps, and rain jackets. However, these chemicals do not break down in the environment and can accumulate in both the environment and the human body over time. PFAS have been detected in Texas waterways, with potential sources including wastewater treatment plants and the discharge of chemicals by manufacturers.
The presence of PFAS in Texas's water systems has raised concerns due to its potential health risks. Studies have linked exposure to certain PFAS with cancer, low birth rates, birth defects, and damage to the liver and immune system. The Texas Commission on Environmental Quality (TCEQ) has implemented regulations and provided assistance to public water systems to address PFAS contamination, including setting maximum contaminant levels and providing resources for treatment options.
To address the issue of plastic pellet pollution, the TCEQ has taken enforcement actions, such as fining companies that fail to control the release of plastic pellets. Additionally, Texas has established programs and standards to manage and improve surface water quality, reduce pollution, and protect natural waterways. These efforts include monitoring and assessing water quality, implementing pollution control projects, and enforcing compliance with water quality standards.
In conclusion, plastic pellets and PFAS chemicals are significant pollutants in Texas waters, posing environmental and health risks. The state has taken steps to address these issues through regulation, enforcement, and the implementation of water quality improvement initiatives. However, the persistent presence of these pollutants highlights the need for continued efforts to protect Texas's waterways and the health of its residents and ecosystems.

Pet waste and stormwater runoff
Pet waste contains harmful bacteria, including E. coli, which can cause gastrointestinal problems and skin reactions. It also contains nutrients that encourage weed and algae growth, making the water cloudy and green, unattractive for swimming, boating, and fishing. Pet waste that is not picked up and disposed of properly can be washed into storm drains by rain, melting snow, or sprinkler runoff, and from there, it ends up in Texas's lakes, rivers, and streams, causing water quality issues.
To prevent water pollution from pet waste, it is important to pick up after your pet and dispose of their waste properly. This can be done by flushing it down the toilet, tossing it in a securely tied plastic bag into a trash can, or burying it at least six inches in the ground away from water sources and gardens.
Stormwater runoff is another major contributor to water pollution in Texas. It occurs when precipitation, such as rainfall or snowmelt, runs off land surfaces, pavements, building rooftops, and other impervious surfaces that do not allow water to infiltrate. As it flows, stormwater runoff can pick up pollutants such as oil and grease, chemicals, nutrients, metals, and bacteria.
In Texas, stormwater runoff is carried through natural or man-made drainage systems, including ditches, pipes, and storm sewer systems. From there, it flows directly into streams, creeks, rivers, wetlands, or coastal waters without treatment. This can lead to the contamination of water sources used for swimming, fishing, and drinking, causing adverse effects on plants, animals, and human health.
To mitigate the impact of stormwater runoff on water quality, it is important to minimize the use of impervious surfaces, properly manage trash and outdoor cleaning activities, and ensure that any potential pollutants are contained and do not come into contact with stormwater.
