Oil refineries, chemical and plastics manufacturers, and fertilizer plants
Oil refineries, for instance, often discharge contaminated wastewater into water bodies. This wastewater contains a range of pollutants, including chemicals and oil by-products, which can be extremely harmful to aquatic ecosystems and human health. Despite policies and regulations, such as the Circular Economy and Environmental Impact Assessments, aimed at promoting sustainable water use in the industry, oil refineries continue to contaminate water worldwide.
Chemical manufacturers, such as the Chemours plant in North Carolina, have been responsible for acute PFAS pollution. PFAS, or per- and polyfluoroalkyl substances, are a family of synthetic chemical compounds that have been found in drinking water sources. These chemicals are often used in industrial processes or as firefighting foam at airports and military bases. The Clean Water Act in the United States mandates that industries disclose the pollutants they discharge, and agencies like the EPA are authorized to stop pollution at its source. However, enforcement of these regulations is often lacking, allowing industries to discharge potentially toxic chemicals into water sources.
Plastics manufacturers contribute to water pollution through the production and conversion of fossil fuels into plastic products, which account for a significant portion of global greenhouse gas emissions. The plastics industry is projected to be a major consumer of oil and a significant contributor to carbon emissions in the future. Additionally, the carcinogenic chemicals present in plastic products can leach into tap water, posing health risks to those who consume it.
Fertilizer plants also play a role in water pollution, particularly through the use of chemical fertilizers containing phosphorus. While phosphorus is a natural nutrient, excess amounts can disrupt ecosystems. Runoff from lawns, roads, and agricultural lands carries phosphorus and other chemicals into waterways, leading to poor water quality. This runoff serves as "junk food" for algae, causing algae blooms that impact aquatic life and the quality of water for human activities like fishing and swimming. To mitigate this issue, it is essential to use water-insoluble fertilizers and apply them carefully, ensuring they do not enter storm drains or nearby water bodies.

Industrial waste from agricultural sites, mines and manufacturing plants
Industrial waste from agricultural sites, mines, and manufacturing plants can have a significant impact on water pollution. About 40% of the land in the United States is used for agriculture, and agricultural chemicals can find their way into water sources through air, soil, soil water, streams, wetlands, and groundwater. Pesticides, such as atrazine, are widely used in agriculture and are often detected in surface water, contributing to water pollution.
Mining is another major contributor to water pollution. The mining process can significantly impact water resources, even long after a mine has closed. Mine waste rock and tailings can contaminate water sources with heavy metals and other toxins. Acid Mine Drainage (AMD) is a natural process where sulphuric acid is produced when sulphides in rocks are exposed to air and water. AMD can severely degrade water quality, kill aquatic life, and make water unusable.
Manufacturing plants also contribute significantly to water pollution. Oil refineries, chemical and plastics manufacturers, and fertilizer plants are some of the biggest culprits. For example, US oil refineries discharge wastewater containing heavy metals, oils, greases, and industrial salts into waterways daily. Chemical fertilizer plants also contribute to water pollution by dumping nitrogen, cyanide, chromium, nickel, lead, and other toxins into waterways. The Environmental Protection Agency (EPA) has a legal duty to protect waterways but has been criticized for not doing enough to tackle industrial water pollution.

Radioactive waste from nuclear energy facilities
The Department of Energy (DOE) in the United States is responsible for treating and disposing of radioactive waste from nuclear weapons programs and commercial nuclear power plants. However, the management and disposal of this waste have faced several challenges and controversies. One of the primary challenges is the lack of a permanent geologic repository for high-level nuclear waste. The DOE has yet to construct such a facility due to ongoing debates among policymakers. As a result, the amount of spent nuclear fuel stored at nuclear power plants continues to increase, posing a significant risk of accidental release.
The safe disposal of high-level nuclear waste is a complex and costly endeavor. While interim storage facilities are currently used to manage existing waste, long-term disposal requires deep geological repositories. The safe and environmentally sound disposal of high-level waste is technologically proven, but the process is expensive and controversial. The DOE has considered alternative approaches, such as vitrification, where waste is immobilized in glass, but even this process faces challenges due to the high costs and operational complexities.
The impact of radioactive waste on water pollution can have far-reaching consequences for both the environment and human health. Radioactive contamination of water sources can lead to the accumulation of toxins in aquatic organisms, threatening their survival and disrupting entire ecosystems. It can also render freshwater systems unfit for human consumption, leading to health issues and increased treatment costs. The economic impact can be significant, affecting sectors such as commercial fishing, recreational businesses, and tourism, which heavily rely on clean water.

Water treatment facilities
The treatment process typically involves primary and secondary levels, with some facilities employing tertiary treatments as well. The primary level of treatment uses screens and settling tanks to remove solid waste, which accounts for approximately 35% of pollutants. The screens remove large objects such as sticks and garbage, while the settling tanks allow sludge to settle and scum to form on the surface. This step is crucial to prevent the clogging of pipes and other equipment in the subsequent treatment stages.
The secondary level of treatment focuses on removing organic matter and reducing the concentration of dissolved solids. This is often achieved through biological processes, such as using bacteria to break down organic waste. Tertiary treatment, if employed, further enhances the quality of treated water by removing any remaining contaminants and disinfecting the water before it is released back into the environment.
However, it is important to note that not all wastewater reaches treatment facilities. In some cases, untreated sewage is directly discharged into rivers, lakes, and oceans, leading to severe water pollution. This can occur due to outdated infrastructure, limited capacity at treatment plants, or improper waste management practices. For instance, combined sewer systems in older cities may struggle to handle large volumes of stormwater, resulting in the discharge of untreated sewage into water bodies during heavy rainfall.
Upgrading and optimizing wastewater treatment facilities are crucial to address these challenges. Implementing new technologies, such as nutrient removal systems and swirl concentrators, can help improve the effectiveness of treatment processes. Additionally, enforcing proper land-use plans and development standards can reduce dispersed-source water pollution, which is challenging to control compared to point-source pollution.

Inadequate regulation and enforcement by the Environmental Protection Agency (EPA)
Industries and industrial sites are a major contributor to water pollution. Many industrial sites produce waste in the form of toxic chemicals and pollutants, and while regulated, some still lack proper waste management systems. In rare cases, untreated industrial waste is dumped into freshwater systems, polluting the water and making it unsafe for human consumption.
The Environmental Protection Agency (EPA) plays a crucial role in enforcing environmental laws and ensuring compliance with environmental requirements. However, there have been criticisms of inadequate regulation and enforcement by the EPA, which has contributed to water pollution.
Firstly, the EPA has been accused of insufficient regulation of industrial waste. Despite the EPA's efforts to enforce the Clean Water and Safe Drinking Water Acts, critics argue that they have not done enough to prevent industrial waste from contaminating water sources. Industrial waste from agricultural sites, mines, and manufacturing plants can contain toxic chemicals that pollute rivers, streams, and other bodies of water. Inadequate treatment or lack of treatment of this waste can have severe consequences for freshwater systems and human health.
Secondly, the EPA has been criticized for its handling of air pollution, which indirectly affects water quality. For example, the EPA considered eliminating a rule restricting power plant smokestack emissions and those from other industrial sites, which could have increased air pollution and had downstream effects on water quality. While the Supreme Court put a hold on this decision, it highlights a potential gap in the EPA's commitment to addressing pollution comprehensively.
Additionally, the EPA's approach to calculating the social cost of carbon has been a point of contention. The Biden administration set the social cost of carbon at $190 per ton, recognizing the economic costs and benefits of regulating polluting industries. However, under the Trump administration, the social cost of carbon was significantly lowered to around $5 per ton, indicating a potential relaxation of regulations on polluting industries.
Furthermore, the EPA has been criticized for its response to accidents at industrial and chemical plants. While the Biden administration tightened safeguards against such accidents, the EPA is now reconsidering these rules, citing concerns about the vulnerability of chemical facilities to attacks. This reconsideration raises questions about the EPA's commitment to enforcing stringent regulations on industries that pose a risk to water quality and public health.
In summary, while the EPA has a crucial role in protecting water quality, there have been criticisms of inadequate regulation and enforcement. These criticisms highlight the complex nature of environmental regulation and the need for a balanced approach that considers both industry and environmental protection.
