The Water Pollution Story: Human Impact And Origins

Water pollution occurs when harmful substances contaminate a body of water, degrading water quality and rendering it toxic to humans or the environment. Water pollution can be traced back to the 1800s when unsanitary living conditions and water contamination were linked to disease epidemics. While the understanding of the health risks associated with water pollution has improved over time, the problem of water pollution persists today. Water pollution is caused by various factors, including industrial and municipal discharge, runoff, spills, and deposition of airborne pollutants. These pollutants can be organic, inorganic, or radioactive, and they have severe consequences for human health, the environment, and the economy.

Industrial Revolution pollution

Water pollution is a severe issue that has altered the course of the earth's history. The Industrial Revolution of the mid-19th century played a significant role in introducing new sources of water pollution. The revolution led to the extensive use of coal, which resulted in smog and soot, causing serious health issues in urban centres.

During the Industrial Revolution, factories began releasing pollutants directly into rivers and streams. The development of the cotton and chemical industries, coupled with poor waste treatment, led to a significant increase in pollution load in rivers. Manufacturers dumped waste into waterways, which mixed with raw municipal sewage, worsening disease epidemics. The complex mix of pollutants included harmful chemicals and microorganisms, degrading water quality and rendering it toxic to humans and the environment.

The environmental impact of the Industrial Revolution's new dams was also significant. These dams blocked migratory fish and flooded upstream meadows, leading to residents taking matters into their own hands by removing flashboards or tearing down structures. The older principle of "reasonable use" was replaced by the notion that water use for manufacturing took precedence, further intensifying pollution.

As the effects of water pollution became evident, an environmental movement emerged in the 1960s, leading to events like Earth Day and legislative victories such as the Clean Air Act (1970) and the Clean Water Act (1972). These pieces of legislation aimed to reduce water pollution and protect water sources. Despite these efforts, water pollution remains a global challenge, with industrial waste continuing to contaminate rivers and lakes, particularly in the developing world.

Sewage systems

The history of sewage systems reveals a long-standing issue with water pollution. The District's sewerage system in the United States, for example, dates back to around 1810 when sewers and culverts were constructed to drain stormwater and groundwater from the streets. However, these early drainage systems were not adequately planned or structurally sound, and sewage was often discharged into the nearest body of water, leading to epidemics of waterborne diseases such as smallpox, typhoid, and malaria.

Despite ongoing improvements to sewage infrastructure, the problem of water pollution from sewage persists today. In the United States, wastewater treatment facilities process about 34 billion gallons of wastewater per day, reducing pollutants before discharging treated water back into waterways. However, aging and overwhelmed sewage treatment systems still release more than 850 billion gallons of untreated wastewater each year, contributing to water pollution.

To address this issue, there have been calls for stronger notification programs to alert people about the presence of raw sewage in water sources. Additionally, projects that focus on preventing sewage overflows, such as green infrastructure initiatives, have been suggested as cost-effective solutions. In the UK, the government has announced plans to overhaul the sewer system, including reducing sewage discharge into designated bathing waters and high-priority nature sites by 2032.

While progress is being made, sewage pollution remains a significant challenge. The underfunding, deregulation, and inadequate monitoring of sewage systems have contributed to the issue. As a result, sewage systems in many countries are struggling to cope with increasing sewage flow, leading to the release of raw or partially treated sewage into the environment, which can have detrimental effects on human health, wildlife, and ecosystems.

Waterborne diseases

Water pollution occurs when harmful substances, often chemicals or microorganisms, contaminate a body of water, degrading water quality and rendering it toxic to humans or the environment. This widespread problem jeopardizes our health, the environment, and the economy.

Cholera is a waterborne disease commonly found in humanitarian emergencies or marginalized villages with poor sanitation and poverty. It is spread through contaminated water and causes severe dehydration and diarrhea. It can be fatal within days or even hours of exposure to the bacteria, but only 1 in 10 people will develop life-threatening symptoms. Cholera can be prevented by washing hands often, only eating completely cooked hot food, and drinking safe water.

Typhoid fever is another waterborne disease that is rare in industrialized countries but prevalent in poor parts of developing nations, with an estimated 20 million cases worldwide each year. It is spread through contaminated food, unsafe water, and poor sanitation. Vaccines are recommended for travelers to areas with poor sanitation and unsafe water, and preventative measures include refraining from drinking water that isn't bottled and sealed and avoiding food from street vendors.

Giardia is a waterborne disease caused by a parasite found in contaminated water sources such as ponds and streams, but it can also be present in town water supplies, swimming pools, and more. While giardia typically clears up within a few weeks, those exposed may experience intestinal problems for years. There is no vaccine for giardia, but it can be avoided by washing hands frequently with soap, not swallowing water while swimming, and drinking only bottled water.

Environmental legislation

Water pollution has been a concern for centuries, with early legislation dating back to the 19th century. However, the modern environmental movement and the push for dedicated water pollution legislation gained momentum in the 1960s and 1970s. The increasing public awareness and concern for water quality led to significant legislative changes and the establishment of dedicated environmental protection agencies.

Federal Water Pollution Control Act of 1948

The Federal Water Pollution Control Act (FWPCA) of 1948 was the first major US law to address water pollution. The act set out the basic legal authority for federal regulation of water quality and established the foundation for the Clean Water Act (CWA).

Clean Water Act and Amendments

The Clean Water Act, enacted in 1972, was a landmark environmental law in the United States. It grew out of the 1969 burning of the Cuyahoga River, which sparked national outrage and brought attention to the issue of water pollution. The act's main objectives were to "restore and maintain the chemical, physical, and biological integrity of the nation's waters," including eliminating the discharge of all toxic pollutants by 1985 and making all navigable waters safe for animal life and human recreation. The CWA established the basic structure for regulating discharges of pollutants and set national water quality standards. It also gave the Environmental Protection Agency (EPA) primary responsibility for enforcing these standards and provided funding to state and local governments for compliance.

The Clean Water Act has undergone various amendments over the years to strengthen and expand its provisions. The 1977 amendments further enhanced the EPA's role in fighting water pollution, with the Water Resources Planning Act giving the Administrator of the EPA a seat on the Water Resources Council. The 1981 revisions streamlined the municipal construction grants process, and the 1987 Water Quality Act replaced the construction grants program with the Clean Water State Revolving Fund to address water quality needs through EPA-state partnerships.

Other Environmental Legislation

Other notable environmental legislation that impact water quality include the National Environmental Policy Act of 1969, which established a national policy to promote environmental enhancement, and the Oil Pollution Act of 1924, which prohibited the intentional discharge of fuel oil into tidal waters. The Public Health Service Act of 1912 expanded the mission of the United States Public Health Service to include studying issues related to sanitation, sewage, and pollution.

Individual actions

Water pollution is a serious issue that affects the health, environment, and economy of a region. It occurs when harmful substances such as chemicals or microorganisms contaminate a body of water, degrading water quality and rendering it toxic. While there are larger, systemic causes of water pollution, there are also individual actions that can be taken to help reduce and prevent it. Recognizing the impact of individual actions is the first step towards minimizing water pollution.

One of the most important individual actions is to properly dispose of waste. This includes not flushing trash or non-degradable products, such as plastic, down the toilet. It is also crucial to pick up after pets, as animal waste contains bacteria and pollutants that can contaminate water sources if not disposed of properly. Maintaining a clean environment extends beyond personal spaces, as it is important to keep public areas, such as streets and creeks, free from litter and trash.

Individuals can also reduce their use of plastic and other harmful chemicals, as well as properly dispose of or recycle chemical cleaners, oils, and non-biodegradable items. This extends to car maintenance, as leaking oil, antifreeze, or coolant from vehicles can contaminate groundwater. Instead of washing your car at home, consider using a commercial car wash, as they are equipped to handle and dispose of dirty and chemical-laced water.

Additionally, individuals can make conscious choices when it comes to consumption. Buying only what is necessary reduces the negative impact on water that can occur during manufacturing. Similarly, purchasing items made from recycled materials and participating in recycling or composting programs can help reduce waste.

By understanding the unique qualities of water in your local area and being mindful of your daily actions, you can play a significant role in preventing water pollution and protecting this valuable resource for future generations.
