Water Pollution: Impact On Us Citizens' Health And Environment

Water pollution is a critical issue in the United States, with far-reaching consequences for the health and well-being of its citizens. The problem became prominent in the 19th century with the growth of mechanized agriculture, mining, and manufacturing industries, and it has only worsened over time. The contamination of water sources by toxic chemicals, sewage, nutrients, and other pollutants has had significant impacts on both human health and the environment.

Water pollution affects Americans in several ways. Firstly, it poses a threat to their health, as contaminated water can lead to various illnesses and diseases, including cancer, cardiovascular issues, kidney failure, hepatitis, and diabetes. Unsafe water is a leading cause of death worldwide, killing more people each year than war and all other forms of violence combined. Additionally, water pollution has economic implications, as individuals and families affected by it incur higher healthcare costs and lose work time due to water-related illnesses. The financial burden is especially high for those who are forced to rely on bottled water.

Furthermore, water pollution disproportionately affects certain communities, with research indicating that Latino, Black, and Indigenous communities are more likely to experience inadequate water and sanitation systems. Immigrants and people living in low-income and rural areas are also disproportionately impacted. This inequality in access to clean water highlights the environmental injustices faced by marginalized communities.

To address water pollution and its impacts on citizens, the United States has implemented various measures, such as the Clean Water Act (CWA) and the Safe Drinking Water Act (SDWA). These laws aim to reduce pollution and improve water quality, but there are still gaps in regulation that need to be addressed.

The impact on health, including the risk of infections and diseases such as cancer and hepatitis

Water pollution in the United States poses a significant risk to public health, and has been linked to various infections and diseases, including cancer and hepatitis.

Cancer Risks

Water pollution has been identified as a contributing factor to cancer cases in the United States. Certain chemicals and contaminants found in polluted water sources are known to increase the risk of cancer. Here are some specific examples:

• Arsenic: Arsenic contamination in drinking water has been linked to cancers of the liver, lung, bladder, and kidney.
• Chlorination Byproducts: The use of chlorine for water treatment can lead to an increased risk of bladder and rectal cancer.
• Agricultural Chemicals: Fertilizers and pesticides used in agriculture can contain toxic chemicals that make their way into water sources, potentially increasing the risk of cancer.
• Hazardous Waste: The presence of hazardous waste in water can expose people to a range of carcinogens.

Hepatitis Risks

Hepatitis A is a waterborne disease that is primarily transmitted through the ingestion of contaminated food and water. Untreated groundwater, especially from private wells, has been identified as a significant source of Hepatitis A outbreaks. Here are some key points regarding Hepatitis and water pollution:

• Outbreaks: Between 1971 and 2009, there were 32 reported outbreaks of Hepatitis A in the United States, resulting in 857 cases.
• Vaccination and Regulations: The introduction of Hepatitis A vaccination and public groundwater regulations has led to a significant decline in reported outbreaks.
• Individual Water Systems: Private wells and springs, which are not subject to the same regulations as public water systems, have been identified as a common source of Hepatitis A outbreaks.
• Fecal Contamination: Contamination of groundwater by fecal matter from septic systems, sewage, or improper well construction can lead to the spread of Hepatitis A.
• Water Treatment: Wastewater treatment facilities play a crucial role in reducing the risk of Hepatitis A by treating sewage and industrial waste before it is discharged back into waterways.

In addition to the specific risks of cancer and hepatitis, water pollution has also been linked to various other health issues. These include respiratory problems, cardiovascular issues, skin rashes, eye infections, and gastrointestinal illnesses. It is important to note that certain vulnerable groups, such as children and pregnant women, are at a higher risk of adverse health effects from water pollution.

The economic burden, with higher healthcare costs and lost labour productivity

Water pollution has had a significant impact on the economic prosperity of the United States, with citizens facing higher healthcare costs and lost labour productivity.

Higher Healthcare Costs

Waterborne diseases continue to be a public health problem in the United States, despite advancements in sanitation. Waterborne illnesses are associated with recreational, industrial, healthcare, agricultural, and medical uses. While classic drinking water-associated diseases such as cholera and typhoid fever have become rare, the transmission patterns have changed, and waterborne illnesses persist.

According to the Centers for Disease Control and Prevention (CDC), there have been almost 1,400 outbreaks reported since the current surveillance system was created in 1971. Estimates of gastrointestinal illness caused by drinking water from public water systems fall between 4 and 33 million annual cases. The economic burden of these illnesses is substantial. For example, the massive 1993 outbreak of cryptosporidiosis in Milwaukee, which sickened 400,000 people, cost an estimated $96.2 million in medical costs and lost productivity.

The five primarily waterborne diseases (giardiasis, cryptosporidiosis, Legionnaires’ disease, otitis externa, and non-tuberculous mycobacterial infection) were responsible for over 40,000 hospitalizations at a cost of $970 million per year, including at least $430 million in hospitalization costs for Medicaid and Medicare patients. An additional 50,000 hospitalizations for campylobacteriosis, salmonellosis, shigellosis, haemolytic uraemic syndrome, and toxoplasmosis cost $860 million annually, with a portion assumed to be due to waterborne transmission.

Lost Labour Productivity

Water pollution also impacts labour productivity, particularly in the agricultural sector. A study on the impact of pollution on worker productivity found that a 10 parts per billion (ppb) decrease in ozone concentrations increases worker productivity by 5.5%. The study analysed data from a large farm in the Central Valley of California, where workers are paid through piece-rate contracts. The results suggest that efforts to reduce pollution can be viewed as an investment in human capital, promoting economic growth.

The United States Environmental Protection Agency (EPA) is currently considering a reduction in the federal ground-level ozone standard of approximately 10 ppb. This potential change underscores the economic significance of the environmental productivity effect, which may have particularly detrimental impacts on agriculture, a prominent sector in the US economy.

In conclusion, water pollution has imposed a significant economic burden on United States citizens. The impacts of water pollution on healthcare costs and labour productivity highlight the need for continued investment in waterborne disease monitoring, economic analyses, and burden estimates.

The environmental impact, including harm to wildlife and ecosystems

Water pollution has had a significant impact on the environment in the United States, causing harm to wildlife and ecosystems. The environmental damage caused by water pollution in the United States is extensive and far-reaching. Here are some key ways in which water pollution has affected ecosystems and wildlife:

• Harm to Aquatic Life: Contaminated water has had a detrimental effect on aquatic life, including fish, seabirds, and marine mammals. For example, water pollution from agricultural runoff contains high levels of phosphorus and nitrogen, which encourage the growth of algal blooms. These blooms produce toxins that are harmful to aquatic life, leading to a reduction in fish populations and the death of seabirds and marine mammals.
• Dead Zones: When algal blooms die, they create "dead zones" in the water. The bacteria produced during the decomposition of algae consume oxygen in the water, creating areas where fish and other aquatic organisms cannot survive.
• Threatened and Endangered Species: Water pollution has put additional pressure on threatened and endangered species in the United States. For example, the Deepwater Horizon oil spill in 2010 had a devastating impact on marine life, including sea turtles and dolphins.
• Eutrophication: Excess nutrients, such as nitrogen and phosphorus, from agricultural runoff and sewage, can cause eutrophication. This process leads to an overgrowth of algae and other aquatic plants, which can deplete oxygen levels in the water, harming aquatic life and creating dead zones.
• Bioaccumulation of Toxins: Water pollution has led to the bioaccumulation of toxins in aquatic organisms. For example, chemicals and heavy metals from industrial and municipal wastewater contaminate waterways, reducing the lifespan and reproductive ability of aquatic organisms. These toxins move up the food chain, with larger fish, such as tuna, accumulating high quantities of toxins like mercury.
• Invasive Species: Water pollution has facilitated the spread of invasive species, which can degrade water quality and harm native species. For example, the introduction of zebra mussels has outcompeted native mussel species and altered the food web for other species.
• Ocean Acidification: Ocean acidification, caused in part by the absorption of carbon pollution, is making it more difficult for shellfish and coral to build their shells. This impacts the nervous systems of various marine organisms, including sharks and clownfish.
• Plastic Pollution: Plastic pollution is a significant issue, with an estimated 75 to 199 million tons of plastic waste in the world's oceans. Marine debris, particularly plastic, can entangle, suffocate, and starve marine animals. It also breaks down into microplastics, which are consumed by fish and can enter the human food chain.

These environmental impacts highlight the urgent need to address water pollution in the United States to protect the country's delicate ecosystems and wildlife.

The social impact, with communities of colour disproportionately affected

Water pollution has had a significant social impact on communities of colour in the United States, who are disproportionately affected by a range of environmental injustices. These communities face unequal access to clean water and are more likely to live in areas with heavy pollution, including unsafe drinking water.

Communities of colour are more likely to be exposed to contaminated water, with higher levels of pollutants such as nitrate, lead, and per- and polyfluoroalkyl substances (PFAS). This is due to various factors, including the siting of industrial facilities, military bases, and landfills near their watersheds, as well as residential segregation and discrimination. For example, in Flint, Michigan, the water crisis sparked nationwide concern about socioeconomic disparities in access to safe drinking water.

The social implications of water pollution for communities of colour go beyond health risks. These communities also face higher water costs and inadequate sanitation infrastructure. Additionally, they have less political influence and are often disenfranchised from decision-making processes, making it challenging to address contamination issues effectively.

The environmental justice movement aims to address these disparities and pursue equitable and sustainable policies. However, despite efforts, water pollution continues to disproportionately affect communities of colour, exacerbating existing social and economic inequalities.

The political response, including the Clean Water Act and other legislation

Water pollution in the United States has been a critical issue since the 19th century, with the development of mechanized agriculture, mining, and manufacturing industries. While laws and regulations introduced in the late 20th century have improved water quality, water pollution remains a significant problem. Here is an overview of the political response to water pollution in the United States, including the Clean Water Act and other legislation:

The Clean Water Act (CWA)

The Clean Water Act, enacted in 1972, is the primary federal law in the United States governing water pollution. Its objective is to restore and maintain the chemical, physical, and biological integrity of the nation's waters. The CWA establishes conditions and permitting for discharges of pollutants into US waters under the National Pollutant Discharge Elimination System (NPDES) and gives the Environmental Protection Agency (EPA) the authority to implement pollution control programs. The Act made it unlawful for any person to discharge any pollutant from a point source into US waters without obtaining an NPDES permit. The EPA issues technology-based effluent guidelines and sets wastewater standards for industries.

Other Legislation

In addition to the Clean Water Act, there are several other laws and regulations that address water pollution in the United States:

• Federal Water Pollution Control Act ( FWPCA ): Enacted in 1948, this law created a comprehensive set of water quality programs and provided financing for state and local governments. It was significantly reorganized and expanded in 1972 and became commonly known as the Clean Water Act.
• Safe Drinking Water Act ( SDWA ): This law sets limits for drinking water contaminants and requires water utilities to test their supplies and report the results.
• Resource Conservation and Recovery Act ( RCRA ): This act includes provisions for groundwater protection.
• Superfund Act: This act provides for the cleanup of contaminated sites and includes groundwater protection provisions.
• Oil Pollution Act ( OPA ): Passed in 1990, this act amended the CWA and provided new requirements for contingency planning, increased penalties for non-compliance, and broadened the response and enforcement authorities of the federal government.
• Water Quality Act ( WQA ): Passed in 1987, this act addressed the issue of stormwater runoff by defining industrial stormwater dischargers and municipal separate storm sewer systems as point sources, requiring them to obtain NPDES permits.
• Water Infrastructure Finance and Innovation Act ( WIFIA ): Passed in 2014, this act provides an expanded credit program for water and wastewater infrastructure projects.

While these laws and regulations have helped improve water quality in the United States, water pollution remains an ongoing issue, and further efforts are needed to address the problem effectively.
