Louisiana's Waterways: Industrial Pollution's Impact And Reality

Louisiana ranks fourth in the US for industrial water pollution, with over 11 million pounds of harmful substances released into state waters in 2020. The state has lenient standards for toxic chemical concentrations, and while it permits the release of certain chemicals, it does not regularly monitor air quality near major polluters. Louisiana's waterways are also affected by agricultural pollution and sewage issues, with more than 90% of assessed water bodies failing to meet quality standards for wildlife or recreation. While industrial pollution is not the primary cause of water contamination in the state, it remains a significant concern, with environmental groups advocating for tighter regulations under the Clean Water Act.

Louisiana's Industrial Water Pollution

Louisiana ranks 4th in the US for industrial water pollution

The report, titled "Wasting our Waterways," was compiled by Environment America, the US Public Interest Research Group Education Fund, and the Frontier Group. It used a federal tool provided by the Environmental Protection Agency (EPA) to weight the toxicity of the plants' releases. Louisiana Environmental Action Network scientist Wilma Subra noted that while no concentration of chemicals exceeded the level that the Louisiana Department of Health would deem unsafe for drinking water, these standards do not account for the cumulative effect of exposure to the chemicals present in the water. Subra added that immunocompromised people, infants, and the elderly are particularly vulnerable to the effects of these chemicals.

The industrial facilities in Louisiana released a variety of harmful substances, including heavy metals, nitrogen, and other pollutants, into rivers, estuaries, and other waterways. These substances have been linked to reproductive health issues, interference with bodily development, and cancer. The report highlighted that the Lake Maurepas watershed was among the top 20 local watersheds in the country for exposure to all three types of pollutants.

The high level of industrial water pollution in Louisiana has been attributed to several factors. Firstly, the state has a significant number of industrial plants, including oil refineries and chemical plants, that emit pollution into the water. For example, the CF Industries nitrogen fertilizer plant in Donaldsonville discharged the most pollution by weight, and the Denka Performance Elastomer plant in Reserve was among the top 20 in the country based on toxicity. Secondly, there is a lack of stringent regulation and enforcement of water pollution laws, such as the Clean Water Act, which has exemptions and loopholes that allow polluters to use toxic materials. The EPA has been criticized for its failure to act when refineries exceed their discharge limits and for its lenient standards for certain pollutants. Additionally, Louisiana's standards for toxic chemical concentrations in the air around plants are more lenient when compared to other states, and the state does not regularly monitor air quality near major polluters.

Fertiliser and sewage are the biggest causes of water pollution

Louisiana ranks fourth in the nation for industrial water pollution. In 2020, industrial facilities released more than 11 million pounds of harmful substances into state waters. However, the biggest causes of water pollution in the state are fertiliser and sewage.

Fertiliser and sewage are the leading causes of water pollution in Louisiana, despite the state's efforts to improve water quality. In 2020, more than 90% of Louisiana's assessed water bodies failed to meet water quality standards for wildlife habitat or recreation. The state is home to the nation's largest expanse of polluted estuaries. While industrial pollution has played a role, agricultural pollution loaded with nutrients creates toxic algal blooms, removing oxygen from the water and harming fish and wildlife.

Nutrient pollution, including fertilisers and sewage, is a significant issue in Louisiana. Excess nutrients from fertilisers, sewage, and other sources can lead to eutrophication, causing low oxygen levels and harmful algal blooms that damage aquatic ecosystems. These nutrients can come from lawn and garden fertilisers in urban areas, as well as wastewater treatment facilities, runoff from urban areas, and farming practices.

Agricultural runoff is a major contributor to water pollution in Louisiana, as it is challenging to trace and regulate. The Clean Water Act of 1972 has limited success in addressing this issue, as agriculture is largely exempt. This has resulted in pollution from fertilisers, pesticides, phosphorus, nitrogen, and bacteria, with similar issues reported in other states like Indiana.

The failure to adequately regulate agricultural pollution has been called "probably the biggest program failure in the Clean Water Act" by Eric Schaeffer, executive director of the Environmental Integrity Project. Louisiana's water management agencies are exploring ways to retain water longer and address flooding, which could help reduce overall runoff and mitigate water pollution. However, broad policy changes to address fertiliser and sewage pollution do not appear to be under immediate consideration in the state.

Louisiana's waterways are the most polluted in the US

Louisiana's waterways are among the most polluted in the United States. In 2020, industrial facilities released more than 11 million pounds of harmful substances into the state's waters, making it the fourth-highest polluter in the country. However, it is important to note that Louisiana is also ranked third in the gross amount of toxic substances dumped into its waterways.

The biggest offender in Louisiana is ExxonMobil, which released nearly 2 million pounds of toxic waste in 2012 from just one Baton Rouge refinery. Other top polluters include meat and poultry processing plants, and five Louisiana plants that landed in the top 50 for the toxicity of their discharges. The Lake Maurepas watershed, located between New Orleans and Baton Rouge, is also a highly polluted area, ranking among the top 20 local watersheds for exposure to all three types of pollutants.

Agricultural pollution, sewage leaks, and fertilizer runoff are significant contributors to Louisiana's water pollution. In 2020, more than 90% of the state's assessed water bodies failed to meet water quality standards for wildlife habitat or recreation. The state also has the largest expanse of polluted estuaries in the nation. Unmaintained home sewage systems allow raw sewage to leak into the soil and contaminate nearby bodies of water, rendering them unsafe for swimming and drinking.

While there have been calls for tighter regulation of water pollution under the Clean Water Act, Louisiana is not currently considering broad policy changes to address these issues. The state's lenient standards for toxic chemical concentrations and lack of regular monitoring of air and water quality contribute to the persistent pollution problems in the state.

Louisiana's water pollution regulations are lenient

Louisiana ranks fourth in the US for industrial water pollution, with more than 11 million pounds of harmful substances released into state waters in 2020. This figure is legal and permitted by the Louisiana Department of Environmental Quality (LDEQ), but it poses a risk to human health, according to national environmental groups and Louisiana advocates.

Louisiana's lenient water pollution regulations are evident in its allowance of toxic chemical discharges into waterways. The state's standards for maximum allowable chemical exposures are notably higher than those of neighbouring states like Texas and Massachusetts. For instance, Louisiana's benzene standard is more than twice as lenient as Texas's, which already falls short of Massachusetts's standards. This discrepancy indicates a lenient regulatory regime that prioritises industrial investment over environmental protection.

The LDEQ has a stated mission to provide comprehensive environmental protection and promote health, safety, and welfare. However, in practice, Louisiana's water quality regulations have fallen short. As of 2020, over 90% of Louisiana's assessed water bodies failed to meet water quality standards for wildlife habitat or recreation. While industrial pollution is a factor, the primary contributors to Louisiana's water pollution are agricultural pollution and sewage issues. Fertiliser runoff creates toxic algal blooms, which deplete oxygen levels, harming fish and wildlife. Additionally, unmaintained home sewage systems leak raw sewage into the soil, contaminating nearby bayous, lakes, and streams.

Despite the LDEQ's efforts to monitor and manage water quality, Louisiana is not currently considering broad policy changes to address water pollution. The state's focus is on retaining water in specific areas and addressing flooding, which could help reduce overall runoff pollution. However, without stricter regulations and enforcement, Louisiana's water quality will continue to face significant challenges, impacting both the environment and public health.

Water pollution is worse in poorer communities

Louisiana ranks 4th in the US for industrial water pollution, with more than 11 million pounds of harmful substances released into state waters in 2020. This figure is legal and permitted by the Louisiana Department of Environmental Quality, but it still poses a risk to human health. Louisiana allows more toxic chemicals to enter its waterways than most other states, and its standards for toxic chemical concentrations in the air around plants are lenient.

Water pollution is a significant issue in poorer communities, and there are several reasons why this is the case. Firstly, communities with higher proportions of minority residents may have less political influence and may be excluded from political and budgetary decision-making processes. As a result, they may have fewer resources to install new treatment technology or develop new water sources when contamination occurs. For example, Native American households are 19 times more likely than white households to have inadequate plumbing, and African American and Latinx households face similar challenges.

In addition, poorer communities may lack access to safe drinking water and sanitation. On the Navajo Nation, for instance, almost 8,000 homes lack access to safe drinking water, and 7,500 have insufficient sewer facilities. In West Virginia, residents drink from polluted streams, and in Nepal, a disturbing study found that 75% of drinking water samples from schools were contaminated with fecal bacteria. Poor system maintenance, infrastructure failures, and natural disasters can also exacerbate water quality issues, even in developed nations. For example, in Flint, Michigan, residents were exposed to toxic lead levels in their drinking water due to inadequate treatment.

Agricultural pollution is another contributor to water contamination in poorer communities. Nitrate, commonly found in drinking water in agricultural regions, has been linked to an elevated risk of cancer and birth defects. In addition, land runoff pollution from unmaintained home sewage systems can leak into the soil and find its way into bodies of water, rendering them unsafe for swimming.

Furthermore, water inequality is not limited to developing countries. For instance, rural areas in Alaska, Russia, and Greenland lack safe in-house water and sanitation facilities, and hauling water into homes is physically demanding and risks contamination. Climate change and population growth will also impact water supply in the coming decades, and increasing groundwater extraction will have environmental costs.

Overall, it is clear that water pollution disproportionately affects poorer communities, and addressing this issue requires a range of solutions, including increased investment in marginalized communities, changes in water management, and stricter regulations on agricultural and industrial pollution.
