Polluted Water: Which State Has The Dirtiest Record?

Water pollution is a pressing issue in the United States, with various states and cities facing contaminated water supplies. While it is challenging to definitively state which state has the most polluted water, several sources indicate significant water quality issues in specific regions. For instance, Indiana has been reported to have the most polluted rivers and streams, with agricultural runoff, particularly manure from large animal farms, being a primary culprit. On the other hand, states like Georgia, Pennsylvania, and Texas also face considerable water pollution problems, with contaminated drinking water sources affecting the health and well-being of their residents. Additionally, specific cities like Flint, Michigan, and Newburgh, New York, have gained notoriety for their water crises, highlighting the pervasive nature of water pollution across the country.

Indiana has the most polluted rivers and streams

Indiana has been ranked as the state with the most polluted rivers and streams in the US. This is according to a 2022 report by the Environmental Integrity Project, which revealed that Indiana has the most miles of rivers and streams deemed too polluted for swimming and recreation. In fact, Indiana has monitored more of its rivers and streams in the past decade than many other states, suggesting that other states could have more polluted waterways than what the data shows.

The main source of Indiana's water pollution is agriculture, particularly the runoff from large animal farms, also known as concentrated animal feeding operations. These farms generate large amounts of manure, which can contaminate local waterways. In addition, agricultural runoff from fertilizer and untreated stormwater can also contribute to water pollution. According to Indra Frank, the health and water policy director for the Hoosier Environmental Council, E. coli, a bacteria indicating faecal contamination, is the top impairment of Indiana's waterways.

The Clean Water Act of 1972 aimed to make all US waterways "fishable" and "swimmable" within 10 years and to eliminate water pollution by 1985. However, 50 years later, the US is still far from achieving these goals, as demonstrated by Indiana's polluted waterways. The law was oriented towards dealing with discharges that come out of pipes, rather than the type of pollution caused by agricultural runoff.

The Environmental Protection Agency (EPA) has been criticised for not holding corporations accountable for water pollution and for not regulating large farms like other industries. Budget cuts to state and federal agencies have also hindered their ability to enforce pollution controls on "non-point sources" like runoff. As a result, Indiana's water utilities are under pressure to remove harmful bacteria and toxic algae, driving up drinking water bills in the state's larger cities.

Texas has the worst public water ratings

The most polluted water systems are in the state’s small rural communities, where resources are scarce, and populations are often around 100 people per provider. Almost 500,000 Texas residents live in areas with contaminated groundwater. Roughly 12.07 million Texans are served with unsafe water, and the quality doesn’t seem to be improving. The latest reports say that Texas still has the country’s most radiated drinking water. Lead, radiation, and arsenic are among the top pollutants, partly due to old pipes and water systems, and partly because of contaminants spilled directly into waterways.

Several towns and cities in Texas have high levels of contaminants in their water, including Lubbock, Midland, Houston, and Brady. Lubbock’s drinking water contains 16 contaminants with levels above acceptable health limits, as well as 30 contaminants of potential concern. Arsenic levels, while within legal limits, are nearly 600 times over the recommended health limits. Midland’s drinking water contains a similar number of contaminants. Houston's water features particles produced by nuclear testing or radioactive mineral deposits, as well as illegal levels of mining waste pollution, including haloacetic acids. Brady, Texas, has the state's highest levels of radium.

The best and most practical way to reduce pollution in drinking water is through a carbon block filtration system. Using microscopic filtration technology, carbon block filters cleanse water of many impurities without requiring a re-route of the water supply. From whole-house systems to small models that sit on your countertop, carbon block filters come in a wide range of sizes and designs.

California's rural farming communities have unsafe drinking water

While Texas has been ranked as the state with the most polluted water in the US, California's rural farming communities, particularly those with Latino and low-income populations, are also struggling with unsafe drinking water.

In 2019, over 1 million California residents received unsafe drinking water, with about 1,600 of the state's public water systems violating the EPA's water quality standards. The problem is especially pronounced in rural farming areas, where communities have experienced decades of groundwater contamination. Arsenic, nitrate, and a chemical called 1,2,3-trichloropropane (1,2,3-TCP) are among the most pervasive contaminants in California's water systems. Long-term exposure to these pollutants can lead to serious health issues, including cancer and developmental problems in children.

The San Joaquin Valley community of Pixley, for instance, has a population of about 3,800 people, and its jobs are largely rooted in agriculture. The widespread use of soil fumigants in the 1950s contaminated the Central Valley groundwater with 1,2,3-TCP, an impurity found in those fumigants. Although the fumigants were eventually pulled from the market or reformulated in California by the 1990s, elevated levels of this chemical continue to taint the water in wells throughout the San Joaquin Valley.

Another community facing water contamination issues is Allensworth in Tulare County, where residents have dealt with arsenic-laced water for decades. Arsenic is naturally occurring in California's rocks and soils but is exacerbated by groundwater over-pumping for irrigation in the San Joaquin Valley. Long-term exposure to arsenic-contaminated water is linked to an increased risk of cancer and adverse effects on fetal and child development.

While the state has provided over $1 billion in grants to help disadvantaged communities address drinking water problems, more than 600 water systems are still at risk of failure, and the estimated cost for full repairs is $16 billion. As a result, rural residents in California must rely on costly bottled water while waiting for systemic solutions.

Pennsylvania's water systems are unsafe

One of the main issues affecting Pennsylvania's water quality is fracking. This has had a profound impact on rural communities in particular, where well water can become discolored and odorous. Another significant contaminant is PFAS, found in the drinking water of approximately 85,000 residents near Philadelphia. PFAS enters the water supply from firefighting foam used at nearby decommissioned military bases.

Furthermore, Pennsylvania's water systems have been found to contain potentially unsafe levels of radium, a naturally occurring radioactive element. While radium is present at low levels in all soil, water, and rocks, certain human activities, such as uranium mining and oil and gas drilling, can increase its concentration in groundwater. Prolonged exposure to radium is a health risk as it can accumulate in the body and increase the chances of developing cancer. According to the Environmental Working Group, hundreds of Pennsylvania water utilities reported levels of radium above health guidelines.

To address these issues, Pennsylvania has been working to implement new policies. However, as of 2019, conditions remained largely unchanged for many small communities. While carbon block filtration systems offer a practical solution to reducing pollution in drinking water, it may take decades to fully remediate the state's water challenges.

Ohio River is one of the most polluted in the US due to industrial and agricultural runoff

The Ohio River is a vital resource, providing drinking water for over 5 million people and supporting a rich biodiversity. However, it is also one of the most polluted rivers in the United States, facing significant challenges due to industrial and agricultural runoff.

The Ohio River Basin has a long history of industrialization, with a range of industries, including mining, manufacturing, and energy production, operating along its banks for centuries. This has resulted in the discharge of various industrial chemicals, heavy metals, acids, and other toxic pollutants into the river, which has severely degraded water quality. For example, in 2020, the steel producer North American Stainless dumped over 3 million pounds of toxic pollution into the Ohio River, more than any other facility in Kentucky. Additionally, the river has been used as a dumping ground for urban and agricultural runoff, with fertilizers, pesticides, and manure washing into the river during rainstorms, leading to nutrient pollution and harmful algal blooms.

Agricultural runoff is a significant contributor to non-point source pollution, which is challenging to control as it does not come from a single, identifiable source. While regulations like the Clean Water Act have helped curb some point source pollution, such as discharges from specific pipes or wastewater treatment plants, non-point source pollution remains a persistent issue. The Environmental Integrity Project report highlights the lack of power of state and federal agencies to enforce pollution controls on non-point sources, and budget cuts have further hindered their ability to address this issue.

The impacts of industrial and agricultural runoff in the Ohio River are wide-ranging. Firstly, it poses health risks to the millions of people who rely on the river for drinking water. Secondly, it harms aquatic ecosystems, leading to severe water quality degradation and affecting aquatic life. The river's biodiversity is also under threat from invasive species, and climate change further exacerbates these issues.

To address these challenges, a holistic approach is necessary. This includes continued monitoring, advancements in treatment technologies, public awareness, and collaborative actions across communities, industries, and governments. The Ohio River Basin Alliance (ORBA) is developing a comprehensive plan to restore the basin, addressing urgent threats such as toxic pollution, sewage contamination, and flooding. Advocates emphasize the need for investments on a scale comparable to those made for other major ecological restoration projects.
