Texas Water Pollution: Who Suffers?

Water pollution in Texas is a pressing issue that affects the state's residents, wildlife, and natural waterways. With a growing population of approximately 29 million people, ensuring access to clean and safe drinking water is essential. However, Texas faces significant challenges in this regard, as its water sources are contaminated with various pollutants, including arsenic, lead, radiation, and toxic chemicals. The state's water quality issues are exacerbated by industrial discharges, lax environmental regulations, and insufficient infrastructure, monitoring, and funding. These factors have led to Texas being ranked as one of the top water polluters in the nation, with serious consequences for human health and the environment.

People in Texas: 29 million residents are affected by the state's water quality issues

Texas is home to approximately 29 million people, and its population is steadily growing. However, the state faces significant challenges in providing safe and clean drinking water to its residents due to various water quality issues. These problems are widespread and impact people across the state, from small, remote communities to large cities like Dallas.

Dallas Water Contamination

The Environmental Working Group (EWG), in collaboration with independent scientists, conducted a study that revealed Dallas' water supply had 37 contaminants. During the test period between 2012 and 2017, ten of these contaminants exceeded the health guidelines recommended by the EWG. The Dallas Water Utility serves nearly 1,200,000 people, highlighting the extent of the impact on the local population.

High Levels of Toxic Substances

Texas has gained an unfortunate reputation as one of the nation's worst water polluters. In 2012, Texas polluters released approximately 16.5 million pounds of toxic chemicals into waterways, second only to Indiana. However, when the toxicity of the pollution is considered, Texas becomes the top state for water pollution. In 2012, the state produced 34 million "toxicity-weighted pounds", a figure 30 times higher than the next state and more than double the combined total of all other states.

The primary source of this toxicity is the Dow Chemical Company plant in Freeport. Despite acknowledging the release of certain chemicals, a spokeswoman for the company disputed the EPA's toxicity measurement.

Health Risks

The contaminants found in Texas's water supply have been linked to various health issues. These include cancer, damage to the brain and nervous system, hormonal disruption, and problems during pregnancy. High levels of arsenic, lead, and radiation, as well as other hard-to-pronounce chemicals, pose significant risks to the well-being of the state's residents.

Infrastructure and Monitoring Challenges

The water quality issues in Texas are exacerbated by deteriorating infrastructure and inadequate monitoring practices. Small and remote communities often suffer the most from polluted water due to a lack of frequent monitoring, insufficient funding, and a shortage of trained staff to oversee water quality. As a result, these communities are disproportionately affected by the state's water pollution problems.

Regulatory and Enforcement Concerns

There are also concerns about the effectiveness of regulatory and enforcement measures in Texas. While the Texas Commission on Environmental Quality (TCEQ) claims to have robust water quality permitting and enforcement programs, critics argue that the state has not done enough to enforce limits on pollution or set stringent enough pollution limits. This has resulted in a situation where companies can flout pollution laws and pay relatively minor fines without facing more significant consequences.

Drinking water: toxic chemicals in drinking water can cause cancer, brain damage, and nervous system issues

Toxic Chemicals in Drinking Water in Texas

Cancer

A US study found that the drinking water supplies of more than six million Americans contain unsafe levels of industrial chemicals that have been linked to cancer and other serious health problems. These chemicals, known as PFASs (polyfluoroalkyl and perfluoroalkyl substances), are used in products ranging from food wrappers to nonstick cookware. PFASs have been linked to an increased risk of kidney and testicular cancers, hormone disruption, high cholesterol, and obesity.

Brain Damage

The presence of inorganic arsenic or cadmium in drinking water can also present a serious hazard. Arsenic exposure has been linked to neurodevelopmental abnormalities, with one study finding that mothers with higher arsenic exposure and folate deficiency were at a higher risk of giving birth to an infant with neural tube defects. Arsenic exposure has also been linked to lower cognitive and motor function in children who consume arsenic-contaminated water for a prolonged period.

Nervous System Issues

Similarly, while cadmium exposure is typically associated with nephrotoxicity, low doses of cadmium in drinking water can promote excess free radical-related oxidative events, with the brain being more sensitive to such changes than other organs. Exposure to neonates is likely to be more harmful compared to adults.

In addition, the use of chlorine and its derivatives for water disinfection can lead to the formation of stable and potentially harmful chlorinated organics. Chlorinated wastewater has been shown to be cytotoxic to mammalian cells.

Other Health Issues

Other health issues associated with toxic chemicals in drinking water include gastrointestinal symptoms, behavioural and cognitive impairments, and neurodegenerative disorders such as Alzheimer's and Parkinson's disease.

Wildlife: polluted water endangers wildlife and the environment

Water pollution in Texas poses a significant threat to the state's wildlife and natural environment. The state's waterways, including streams, rivers, and lakes, have been inundated with toxic substances, with Texas ranking first in the nation for toxic discharges. This has had, and continues to have, a detrimental impact on aquatic ecosystems and the wildlife that inhabits them.

Sources of Water Pollution in Texas

Texas faces water pollution from various sources, including industrial discharges, agricultural runoff, and urban runoff. The state's lax regulatory environment and permissive attitude towards industrial waste have led to a significant increase in toxic substances released into Texas water bodies. Between 2007 and 2020, the amount of toxic substances released into Texas water increased from 13.2 million to 16.7 million pounds.

Agricultural activity is a major contributor to non-point source pollution in Texas. The use of pesticides, fertilizers, and other chemicals in crop irrigation and plowing generates pollutants such as nutrients, pesticides, insecticides, herbicides, and sediment, which make their way into nearby water bodies.

Urban areas also contribute to non-point source pollution through the use of fertilizers, herbicides, and insecticides on lawns, as well as sediment from construction sites and toxic chemicals from roads and parking lots.

Impact on Wildlife and the Environment

The high levels of pollutants in Texas's water have severe consequences for the state's wildlife and environment. Contaminants such as arsenic, lead, radiation, and various chemicals have been detected in water supplies, posing risks to both human and animal health. These substances can cause cancer, damage to the brain and nervous system, hormonal disruptions, and problems during pregnancy.

Additionally, nitrate compounds, a common component of fertilizer runoff, account for a significant proportion of toxic releases. These compounds, along with heavy metals and other toxic substances, can accumulate in people and animals, leading to long-term health issues.

The reduction in water quality has threatened native fish and wildlife species that rely on clean water. As water pollution increases, aquatic life, including fish, birds, and other wildlife, will suffer. This will also impact humans, as water that cannot support aquatic life will not be suitable for human needs.

Furthermore, Texas's growing population and increasing water demands will likely lead to a decrease in water flow in rivers and streams, altering ecosystems, habitats, and wildlife that depend on these water sources. The state's bays and estuaries, which provide commercial, recreational, and conservation benefits, are particularly vulnerable to the diminished freshwater inflows.

Conservation Efforts

Texas has implemented several measures to address water pollution and conserve its natural resources. The Texas Wildlife Action Plan, developed in collaboration with partners, stakeholders, and the public, aims to prevent species from becoming federally listed as threatened or endangered and to enhance the state's quality of life.

The state has also received grants from the U.S. Environmental Protection Agency (EPA) to support water pollution control and management programs. In 2020, the EPA awarded $1.2 million to the Texas Commission on Environmental Quality for water pollution control, and in 2020, the Texas State Soil and Water Conservation Board received $3.8 million to manage non-point source water pollution.

Despite these efforts, Texas still has a long way to go in ensuring the safety of its waterways. The state must continue to address industrial waste discharges, agricultural runoff, and urban pollution to protect its wildlife and environment from the detrimental effects of water pollution.

Swimming and fishing: contaminated water can make swimming and fishing unsafe

Texans love their beaches. From swimming in the warm waters of South Padre Island to fishing in Sabine Pass, Texas' beaches are a source of enjoyment for millions of citizens and tourists each year. However, contaminated water can pose serious health risks, making swimming and fishing unsafe.

Water pollution in Texas is a significant issue, with the state facing major drinking water quality problems and high levels of toxic substances in its waterways. A report by Environment America found that Texas ranks first in the nation for toxic discharges into streams, rivers, and lakes, with 16.7 million pounds of toxic substances released into Texas water in 2020. These toxic substances include nitrate compounds, heavy metals such as lead, solvents, and persistent bioaccumulative toxics like mercury and dioxin.

The effects of water pollution are felt by those who enjoy swimming and fishing in Texas' waterways. A report by the nonprofit group Environment Texas found that 90% of Texas beaches tested in 2022 for fecal bacteria tested positive at least one day. High levels of fecal bacteria can pose health risks to swimmers, including gastrointestinal illness, respiratory disease, ear and eye infections, and skin rashes. Each year, millions of people in the U.S. become ill from swimming in contaminated water, with illnesses ranging from mild to serious.

The causes of beach pollution in Texas include urban and agricultural runoff, sewage overflows, and factory farms. Reckless development, outdated sewer systems, and certain agricultural practices also contribute to the problem. To address this issue, major financial investments are needed to improve infrastructure and stop sewage overflows and runoff pollution. By implementing solutions at the state, county, and city levels, Texas can work towards ensuring that its beaches are safe for swimming and fishing, protecting the health of its citizens and the environment.

In addition to the risks posed to swimmers and fishers, water pollution in Texas also affects the state's drinking water supply. A report by the Environmental Working Group found that Dallas' water supply, serving nearly 1.2 million people, contained 37 contaminants during the test period between 2012 and 2017, 10 of which exceeded the health guidelines. These contaminants have been linked to cancer, damage to the brain and nervous system, hormonal disruption, and problems in pregnancy.

Remote communities: small and remote communities often have the most polluted water

Texas is facing a water quality crisis, with the state's drinking water supply being contaminated by arsenic, lead, radiation, and other toxic chemicals. This crisis affects all communities, but small and remote communities are particularly vulnerable. The water in these areas is often the most polluted due to several factors, including deteriorating infrastructure, infrequent monitoring, insufficient funding, and a lack of trained staff.

Deteriorating infrastructure is a significant issue in remote communities. Aging water treatment facilities and pipelines can leak contaminants into the water supply, and outdated equipment may not effectively remove pollutants. In addition, remote areas may rely on septic systems or wells that are more susceptible to contamination from nearby sources, such as agricultural runoff or industrial waste.

Infrequent monitoring of water quality exacerbates the problem. Remote communities often lack the resources and trained personnel to conduct regular water quality tests, allowing pollution to go undetected or untreated. Even when issues are identified, there may be delays in implementing solutions due to a lack of funding or expertise.

Insufficient funding is another critical factor. Small and remote communities may have limited financial resources to invest in water treatment and infrastructure upgrades, relying instead on aging facilities that are less effective at removing contaminants. This lack of funding also contributes to a shortage of trained staff, as skilled professionals may be attracted to better-paying opportunities in larger urban areas.

The shortage of trained staff further compounds the problem. Remote communities may struggle to find qualified individuals to operate and maintain water treatment facilities, perform regular maintenance, and respond to emergencies, such as water main breaks or chemical spills. As a result, water quality issues may persist or worsen over time.

The combination of these factors results in small and remote communities in Texas facing some of the most severe water pollution challenges in the state. It is crucial to address these issues by allocating more resources, improving infrastructure, conducting frequent monitoring, and providing training and support to ensure that all communities have access to clean and safe water.
