Water Pollution: A Historical Concern For Our Planet

Water pollution has been a concern for centuries, with the earliest instances of pollution being linked to human and animal waste, as well as garbage. The Industrial Revolution of the 19th century further exacerbated the issue, introducing new sources of water pollution. In the 1960s, an environmental movement emerged, leading to the creation of Earth Day and legislation such as the Clean Water Act in 1972. Despite these efforts, water pollution remains a pressing issue, with industrial and municipal facilities continuing to discharge pollution into waterways, and over 40% of American waterways being unsafe for swimming and fishing.

Water pollution and the Industrial Revolution

Water pollution has been a concern for centuries, with the earliest ancestors of humans contributing to the problem through the creation of unsanitary living conditions and water contamination. During the Middle Ages, diseases such as cholera and typhoid fever broke out across Europe due to unsanitary conditions caused by human and animal waste.

However, the Industrial Revolution of the mid-19th century significantly exacerbated water pollution, introducing new sources of pollution and intensifying existing ones. The development of the cotton and chemical industries, for example, increased the pollution load in rivers, leading to a decline in the biota supported by the water.

During this time, factories began releasing pollutants directly into rivers and streams, with many streams and rivers becoming open sewers as cities grew around mills and factories. Manufacturers dumped millions of gallons of waste into waterways, which mixed with raw municipal sewage, worsening disease epidemics. The complex mix of pollutants included human-produced sulfur and nitrogen compounds, which negatively impacted plants, fish, soil, forests, and building materials.

The environmental impact of the new dams built during this time was also significant. These dams blocked migratory fish and flooded upstream meadows, leading to protests and lawsuits from local residents. Despite this, courts in the 19th century increasingly interpreted riparian law in favor of industry, prioritizing water use for manufacturing over fishing and farming.

It wasn't until the 1960s and 70s that an environmental movement emerged, seeking to address the tide of pollutants flowing into the planet's ecosystems. This movement led to legislative victories such as the Clean Air Act (1970) and the Clean Water Act (1972) in the US, and a similar movement in England with the creation of boards of health and the passing of pollution control laws.

Early legislation: The Rivers and Harbors Act of 1899

Water pollution has been a concern for as long as there have been human civilizations. As populations grew, so did the risk of disease and the incidence of unsanitary living conditions. During the Middle Ages, diseases such as cholera and typhoid fever were direct results of the unsanitary conditions caused by waste and garbage.

The Industrial Revolution of the mid-19th century brought new sources of water pollution, and by the middle of the 20th century, people began to understand the link between water contamination and disease. This understanding sparked an environmental movement in the 1960s, which led to legislative victories such as the Clean Air Act (1970) and the Clean Water Act (1972).

One of the earliest pieces of legislation aimed at addressing water pollution was the Rivers and Harbors Act of 1899. This act was concerned with the obstruction of navigable waters in the United States. It prohibited the creation of any obstruction that could hinder navigation without authorization from Congress. The act also regulated the construction of any structures, such as wharves, piers, or jetties, in ports, harbors, canals, or navigable rivers. Any modifications to the course, location, or capacity of navigable waters were also subject to approval by the Chief of Engineers and the Secretary of War.

The Rivers and Harbors Act of 1899 was a significant piece of legislation as it was one of the first attempts to address the issue of water pollution and the protection of water resources. The act recognized the importance of maintaining unobstructed waterways for navigation and commerce. By prohibiting unauthorized obstructions and regulating construction activities, the act helped to ensure the free flow of water and prevent potential sources of pollution.

While the Rivers and Harbors Act of 1899 was a step forward in addressing water pollution, it had its limitations. It primarily focused on the physical obstructions and modifications to waterways, rather than directly addressing the issue of water contamination. In the years that followed, more comprehensive legislation, such as the Clean Water Act of 1972, was enacted to specifically target water pollution and improve water quality.

The Clean Water Act

Water pollution has been a concern for centuries, with the earliest ancestors facing problems of bacteria and diseases caused by water contamination. In the Middle Ages, diseases such as cholera and typhoid fever were direct results of unsanitary conditions caused by waste and garbage. By the 1800s, the link between unsanitary living conditions, water contamination, and disease epidemics was established.

The Environmental Protection Agency (EPA) has played a crucial role in implementing the Clean Water Act. Through the EPA, pollution control programs have been established, including setting wastewater standards for industries and developing national water quality criteria for pollutants in surface waters. The EPA's National Pollutant Discharge Elimination System (NPDES) permit program controls discharges from point sources into navigable waters, ensuring that pollutant discharges are regulated.

Earth Day and environmental activism

Water pollution has been a concern for a long time, with the earliest ancestors facing problems caused by bacteria and diseases due to unsanitary conditions. In the 1300s, the Black Death swept across Europe, caused by the bacterium Yersinia pestis, which thrived in the unsanitary conditions of the time. By the 1800s, the link between unsanitary living conditions, water contamination, and disease epidemics was established.

The Industrial Revolution of the mid-19th century introduced new sources of water pollution, and by the middle of the 20th century, countries worldwide were feeling the effects of these changes. In the 1960s, an environmental movement emerged, giving rise to events like Earth Day and legislation such as the Clean Air Act (1970) and the Clean Water Act (1972).

Earth Day is the world's largest environmental movement, with over 100 million people worldwide participating in Earth Day 2020, marking the 50th anniversary. The first Earth Day was held on April 22, 1970, and was founded by Senator Gaylord Nelson and Denis Hayes. It was a response to an oil spill off the coast of Santa Barbara, California, in 1969, which saw over 3 million gallons of oil leaked into the ocean, devastating local wildlife.

Earth Day was created to raise awareness of the dangers of water and air pollution and their impacts on our health and the environment. The event has grown beyond college campuses, expanding into a national event with a significant impact that continues to evolve. Earth Day organizers wanted the environment to become part of the political agenda, and it has helped spur grassroots activism, leading to various federal environmental policies and legislation.

Today, Earth Day is still crucial as it provides an opportunity for education about environmental issues, highlighting the importance of protecting our planet. It also serves as a reminder to make better choices in our daily lives to protect the Earth and address the climate crisis.

Water pollution today

Water pollution has been a concern for centuries, but it has become an increasingly pressing issue in modern times. Today, water pollution poses a significant threat to both human health and the environment. Our rivers, reservoirs, lakes, and seas are inundated with chemicals, waste, plastics, and other pollutants, rendering them toxic and unsafe. According to the United Nations (UN), 2.2 billion people lacked access to safe drinking water in 2022, and over 2 billion people live in water-scarce regions with high levels of water stress.

Water pollution occurs when water becomes contaminated with toxic substances, often chemicals or microorganisms. This contamination can occur through various means, including industrial waste discharge, city sewage, agricultural runoff, and oil spills. For example, the 1989 Exxon Valdez oil spill dumped approximately 11 million gallons of crude oil into the sea off Alaska's Prince William Sound. Oil pollution can also enter the sea via factories, farms, and cities, as well as through the shipping industry.

Agricultural practices contribute significantly to water pollution. Rainwater washes fertilizers, animal waste, and pesticides from farms into nearby waterways, contaminating the water with high levels of phosphorus and nitrogen. This contamination leads to the growth of algal blooms, which produce toxins harmful to fish, seabirds, marine mammals, and even humans. As these algal blooms decompose, they create "dead zones" in the water where fish cannot survive due to a lack of oxygen.

Additionally, plastic pollution has become a pervasive issue in our oceans. With the widespread use of plastics, it is estimated that there are 75 to 199 million tons of plastic waste in the world's oceans. As plastic breaks apart, microplastics form, which are then consumed by fish and potentially enter the human food chain. Radioactive waste is another concern, as improper disposal can contaminate water sources and pose hazards to humans, marine life, and the environment for thousands of years.

To address water pollution, various legislative actions have been taken, such as the Clean Water Act in 1972, which aimed to reduce water pollution and set limits on industrial discharges. Regional boards, such as those in California, also work to oversee and enforce pollution abatement programs. However, despite these efforts, water pollution remains a critical issue today, with industrial and municipal facilities continuing to discharge pollution into waterways, and a significant proportion of American waterways unsafe for swimming and fishing.
