Water Pollution: Which State Has The Dirtiest Water?

Water pollution is a pressing issue in the United States, with industrial facilities releasing millions of pounds of toxic substances into waterways. While many states struggle with contaminated water, some stand out for their particularly poor water quality. From Georgia's polluted rivers and wells to Puerto Rico's water systems that frequently violate EPA standards, the issue is widespread and affects millions of people. California, Washington, Ohio, Texas, and Arizona also face significant water pollution challenges, with unsafe levels of contaminants posing health risks to vulnerable populations.

California's rural communities have arsenic- and uranium-contaminated water systems

California has a long history of drinking water problems, with many of its rural communities having arsenic- and uranium-contaminated water systems. In California, 12 school districts serving over 5,000 students had arsenic levels that averaged from 30% higher to three times the federal limit of 10 parts per billion. Arsenic is a highly carcinogenic element that can seep into the water table from deposits in the soil and bedrock. It is also a poison if consumed in high concentrations and has been linked to an increased risk of bladder and lung cancer, especially if exposure occurs early in life.

In the community of Allensworth, California, residents know that it is not safe to drink water from the wells in their town. UC Berkeley engineers are collaborating with community leaders in Allensworth to field test a new arsenic treatment system that could help provide safe drinking water to low-income and rural communities. The system, housed within a small grey shed on a farm, has been drawing groundwater from the agricultural well and reducing its arsenic levels.

In addition to arsenic, uranium contamination is also a concern in California's water systems. Uranium is a radioactive element that can occur naturally in the environment but can also be released into the water through human activities such as mining and the use of fertilizers. Uranium in drinking water can pose serious health risks, including kidney damage and an increased risk of cancer.

The state of California has recognized the urgency of addressing these water quality issues, and efforts are being made to improve the situation. Researchers from the Environmental Integrity Project (EIP) have documented multiple cases of arsenic-contaminated water in systems that serve more than 55,000 people statewide, with poor and rural communities affected the most. The state is working to implement solutions, such as the use of Iron Electrocoagulation (Fe-EC) systems, to effectively remove arsenic from contaminated groundwater sources and provide safe drinking water to its residents.

While California's water challenges are significant, ongoing research, collaboration, and innovation are driving progress toward ensuring that all communities have access to clean and safe drinking water.

Texas has the country's most radiated drinking water

Texas has the dubious distinction of having the country's most radiated drinking water. In 2019, 3,358 of Texas's public water systems violated the Environmental Protection Agency's (EPA) water quality standards, with 455 being serious violators. This has led to Texas being ranked as having the most polluted water in America.

The state's water woes are not limited to radiation, however. Texas also struggles with contaminated groundwater, which affects nearly 500,000 residents. The most polluted water systems are typically found in small rural communities, where resources are scarce and populations are sparse, at around 100 people per provider. These communities often lack the financial means to implement the latest water treatment technologies, which can be expensive.

The main sources of radionuclides in Texas's drinking water are the Hickory Aquifer in Central Texas, the Ogallara Aquifer in North Texas, and the northern portion of the Gulf Coast Aquifer. These natural sources typically produce alpha particles, specifically radium, uranium, and overall alpha radioactivity. The presence of these radioactive substances in drinking water increases the risk of kidney damage and cancer for those who consume it.

The issue of contaminated drinking water is not unique to Texas, however. Other states, such as Georgia, Washington, and Pennsylvania, also face significant water quality issues. In Georgia, for example, polluted rivers, streams, and wells result in drinking water that does not meet national quality standards. Similarly, Washington's water supply is contaminated with arsenic, uranium, nitrate, radon, and other harmful substances, many of which are known carcinogens.

Addressing water pollution and ensuring access to safe drinking water is a pressing concern for many states across the country. While Texas currently holds the unfortunate distinction of having the most radiated drinking water, it is not alone in facing these challenges.

Ohio's water is tainted with iron, sulfate, and other mineral compounds

While Ohio is one of America's largest industrial centres, it is also home to some of the country's worst drinking water. The state's large-scale industrial operations have significantly contributed to high levels of lead in its tap water, leading to brief shutdowns of schools and businesses.

There are several methods to remove iron from water, including water softening, chemical oxidation, and filtration. Water softeners can remove small amounts of iron, but the iron will quickly plug the system. Chemical oxidation using chlorine or hydrogen peroxide and filtration is also effective, but proper dosing can be difficult and carries health risks if improperly administered. Iron filters, such as a manganese greensand filter, are a common treatment for high levels of iron in water.

Other states with poor water quality include Texas, which has the country's most radiated drinking water, and Washington, which has one of the most contaminated water supplies in the US. Arsenic, chloroform, chromium, nitrate, radon, radium, and uranium are just a few of the contaminants found in Washington's water, and in many communities, these levels exceed national safety standards.

Washington's water contains arsenic, uranium, nitrate, radon, and radium

While Texas is said to have the most polluted water in America, with nearly 12.07 million Texans served with unsafe water, Washington is also known for its contaminated water supply. Washington's water contains arsenic, uranium, nitrate, radon, and radium, among other contaminants.

Arsenic is a naturally occurring element found in soil, rocks, water, and air. It is, however, a known carcinogen, and long-term exposure to high levels of arsenic may result in skin or gastrointestinal cancers. Uranium is also a naturally occurring radioactive element that decays into radium, another radioactive element, and then into radon gas. Radon is a hazardous gas that may accumulate in wells due to decaying uranium in the soil. Nitrate is found naturally in ground and surface water, but it can also come from fertilizer runoff from agriculture, causing elevated concentrations. While nitrate itself does not pose a danger to health, it can combine with certain bacteria to form nitrogen dioxide gas, which can lead to illnesses like nausea, dizziness, and headaches.

Washington's water crisis is attributed to various factors, including a growing population that increases pollution and pressure on water sources, low pH, low levels of dissolved oxygen, stormwater runoff, warm water temperatures, toxins, and bacteria. The biggest contributor to water contamination is stormwater runoff, which picks up contaminants like animal waste, pesticides, fertilizers, oil, and microplastics as it flows over surfaces.

The presence of these contaminants in Washington's water has severe health implications. Almost all of these chemicals are known carcinogens, and exposure to them can lead to developmental issues, liver damage, and reproductive difficulties. The vulnerable populations, including children, pregnant women, and the elderly, are at an even higher risk of adverse health effects.

Georgia's water pollution is a problem across the state

A report by the Environmental Working Group (EWG) found harmful contaminants in the Georgia water supply that can have serious health impacts, including cancer, developmental issues in children, and problems during pregnancy. The report identified ten harmful contaminants in the water supplies of 30 Georgia towns or water utilities, affecting over 10,000 people. These contaminants included total trihalomethanes (TTHMs), which are linked to bladder cancer, skin cancer, and fetal development issues.

The EWG's findings are supported by the Environmental Protection Agency's (EPA) Enforcement and Compliance History Online (ECHO) database, which collects compliance and enforcement-related information for drinking water utilities nationwide. The ECHO database revealed that Georgia's water utilities had accrued violation points based on specific problems, including violations of health-based drinking water standards. These violations highlight the state's struggle to maintain safe and healthy water supplies for its residents.

Georgia's water pollution is not just a concern for those on public utilities; private well owners also need to be vigilant. Scott Meschke, a professor of environmental and occupational health sciences, advises private well owners to regularly monitor and test their water to ensure its safety. The Georgia Water Coalition's "Dirty Dozen" list further emphasizes the state's water quality issues, annually highlighting the twelve worst offenses to Georgia's water resources.

While Georgia's water pollution is a pressing issue, it is not the only state facing such challenges. Other states, like Texas, Pennsylvania, and California, have also been noted for their water quality issues, with high levels of radiation, arsenic, and other contaminants affecting millions of residents. However, Georgia's water pollution remains a significant concern, and efforts are needed to improve the state's water quality and ensure safe and healthy drinking water for its residents.
