Industrial Revolution's Water Pollution: A Historical Perspective

Water pollution has been a problem since the appearance of our earliest ancestors, but it intensified with the advent of the Industrial Revolution. As industrialization took hold, factories began releasing pollutants directly into rivers and streams, causing a new kind of pollution: industrial waste. In the 19th century, as cities grew around mills and factories, many streams and rivers became open sewers, with manufacturers dumping waste into waterways where it mixed with raw sewage. This worsened disease epidemics and prompted major cities to take measures to control waste. In the US, the Clean Water Act was passed in 1972, setting limits on what industries could discharge into water. However, industrial water pollution remains a significant issue, with corporations continuing to dump toxic waste into waterways.

The Industrial Revolution

Water pollution is not a new phenomenon, and it has been a problem since the earliest human ancestors. However, the Industrial Revolution significantly intensified water pollution as factories began releasing pollutants directly into rivers and streams. During this period, corporate investors established mills and factories that harnessed water power on a much larger scale, producing a vast array of goods, including textiles, shoes, paper, and iron. The environmental impact of these new industrial enterprises was immediate and far-reaching. The construction of ever-higher permanent dams, for instance, blocked migratory fish and caused upstream flooding.

As industrialization expanded and cities grew around mills and factories, many streams and rivers became open sewers. Manufacturers discharged millions of gallons of waste into waterways, which mixed with raw municipal sewage, exacerbating disease epidemics. Local and state governments attempted to address the issue by creating boards of health and enacting pollution control laws. However, even the strongest legislation had loopholes and faced significant opposition from corporations, who often filed lawsuits to challenge these laws.

In the United States, the state of Massachusetts passed a pioneering pollution control law in 1878, but manufacturers successfully lobbied to weaken its enforcement. Similarly, in the late 1800s, Chicago built the first major sewage system to treat wastewater, and other U.S. cities followed suit. These efforts to control waste and improve sanitary conditions made cities healthier and more attractive to potential residents.

By the late 18th and early 19th centuries, coal came into large-scale use during the Industrial Revolution, leading to increased air pollution and smog. The Great Smog of 1952, caused by pollutants from factories and home fireplaces, killed at least 4,000 people in London. This incident, along with other environmental disasters, spurred grassroots activism and the creation of federal legislation to combat air and water pollution, such as the Clean Air Act (1970) and the Clean Water Act (1972).

While legislation and technological advancements have helped reduce industrial emissions, water pollution remains a significant problem today. Industrial activity continues to release pollutants into water bodies, including heavy metals, nitrogen, phosphorus, and organic carbon. These contaminants endanger human health, harm wildlife, and degrade water sources, making them unfit for swimming, fishing, and drinking.

Pollution control laws

The Industrial Revolution saw factories releasing pollutants directly into rivers and streams, intensifying water pollution. By the 1800s, people began to understand the link between unsanitary living conditions, water contamination, and disease epidemics. This prompted cities to implement measures to control waste and garbage, with Chicago building the first major sewage system in the United States in the mid-1850s to treat wastewater.

As cities became more populated towards the end of the 19th century, industrialized cities in Europe and the United States faced a new challenge: industrial waste from factories. In the United States, wastewater treatment facilities play a crucial role in reducing pollutants such as pathogens, phosphorus, nitrogen, heavy metals, and toxic chemicals in industrial waste. However, aging and overwhelmed sewage systems also contribute to the problem, releasing billions of gallons of untreated wastewater annually.

To address water pollution, various laws and regulations have been enacted over the years. The Federal Water Pollution Control Act, commonly known as the Clean Water Act (CWA), was enacted in 1972 and serves as the principal law governing pollution control and water quality in the United States. The CWA establishes standards for discharges of pollutants into waterways and regulates quality standards for surface waters. It also made it unlawful to discharge pollutants from a point source into navigable waters without a permit through the National Pollutent Discharge Elimination System (NPDES).

The Clean Water Act has been amended multiple times to strengthen its effectiveness, such as the Oil Pollution Act of 1990, which prohibits the discharge of oil into navigable rivers. The Water Cess Act was also passed to generate financial resources for pollution control and requires certain industries to pay a tax for water effluent discharge.

In addition to federal legislation, state-level efforts are also in place. The State Pollution Control Boards are authorized to establish and enforce effluent standards for factories, with the power to test equipment and samples. The Air Act, similar to the Water Act, expanded the authority of central and state boards to include air pollution control, requiring industries to obtain permits and follow emission standards.

Industrial waste

Water pollution has been a problem since the earliest human ancestors, but it intensified with the advent of the Industrial Revolution. As factories and mills began to harness water power on a larger scale, they also started releasing pollutants directly into rivers and streams. By the 1800s, people began to understand the link between water contamination and disease epidemics, prompting cities in the US and Europe to take measures to control waste. However, as cities became more populated towards the end of the 19th century, they experienced a new kind of pollution: industrial waste from factories.

During this time, manufacturers dumped millions of gallons of waste into waterways, which mixed with raw municipal sewage and worsened disease outbreaks. Local and state governments attempted to address the issue by creating boards of health and passing pollution control laws, such as the pollution control law passed by Massachusetts in 1878. However, these laws had significant gaps and faced strong opposition from corporations, who often filed lawsuits to challenge them.

The problem of industrial water pollution continued to grow in the 20th century. In 1969, chemical waste released into Ohio's Cuyahoga River caused it to catch fire, becoming a symbol of the environmental neglect and destruction of natural resources caused by industrial pollution. This incident, along with increasing environmental awareness, spurred grassroots activism and led to the creation of federal legislation such as the Clean Water Act in 1972.

Today, industrial water pollution remains a significant issue, with oil refineries, chemical and plastics manufacturers, and fertilizer plants being some of the biggest culprits. These industries discharge wastewater containing heavy metals, oils, greases, industrial salts, and toxic chemicals into waterways, leading to deadly algae blooms and mutations in freshwater wildlife. Additionally, the agricultural sector is a major water polluter, with farming and livestock production contributing to contamination in rivers, streams, wetlands, and lakes.

Efforts to reduce industrial water pollution include legislation such as the Water Framework Directive (WFD) and the Industrial Emissions Directive (IED) in the EU, which aim to protect water bodies from industrial emissions. While industrial releases of certain pollutants have declined between 2010 and 2022 in Europe, data gaps and limitations in reporting make it challenging to fully assess the impact of industrial activities on water pollution.

Waterways as open sewers

Waterways have been used as open sewers for centuries, with pollution intensifying during the Industrial Revolution. The Industrial Revolution saw factories releasing pollutants directly into rivers and streams, causing water contamination and contributing to disease epidemics.

While people began to understand the link between unsanitary living conditions, water contamination, and disease in the 1800s, the issue of industrial pollution continued to grow. By the late 18th and early 19th centuries, coal was being used on a large scale, leading to increased smog and soot that had detrimental effects on the health of urban residents.

The situation worsened with the advent of the Industrial Revolution, as factories began discharging pollutants directly into waterways. This resulted in rivers and streams becoming contaminated with toxic substances, such as chemicals, heavy metals, and waste. The agricultural sector also contributed significantly to water pollution, with farming and livestock production accounting for about 70% of global freshwater consumption and being a major source of water contamination.

The issue of waterways being used as open sewers persists in modern times, with several examples from the 21st century. In 2020, Quebec's waterways were described as "open sewers" by various organizations, highlighting the need for the province to renovate its outdated treatment plants. Similarly, in 2023, sewage spills into England's waterways more than doubled, with heavy rain being a contributing factor. This led to an increase in pollution and health issues, with people reporting illnesses after swimming in the sea.

Environmental impact

The environmental impact of water pollution has been significant since the earliest human ancestors appeared. As human populations have grown, so have the instances of disease and bacteria, with the Middle Ages seeing diseases such as cholera and typhoid fever spread across Europe due to unsanitary conditions.

The Industrial Revolution saw a marked increase in water pollution, as factories began releasing pollutants directly into rivers and streams. The scale of manufacturing and production grew, and with it, the amount of waste produced. This waste was often dumped into waterways, causing severe health issues for those living in the surrounding areas. As cities became more populated towards the end of the 19th century, cities across Europe and the United States experienced a new kind of pollution: industrial waste. In 1878, Massachusetts passed a pollution control law, but manufacturers filed lawsuits to challenge it, and the law was weakened.

In the 20th century, several legislative victories were won in the battle against water pollution, such as the Clean Air Act (1970) and the Clean Water Act (1972). The Clean Water Act provides money to improve sewage treatment plants and sets limits on what industries and treatment plants can discharge into the water. Despite these efforts, water pollution continues to be a significant issue, with agricultural pollution being the top source of contamination in US rivers and streams. Oil refineries, chemical and plastics manufacturers, and fertilizer plants are also major polluters, releasing heavy metals, oils, greases, and industrial salts into waterways.

In recent years, there has been a decline in industrial releases of pollutants into Europe's waterways, with emissions of heavy metals and nitrogen decreasing. However, water pollution remains a pressing issue, with only 40% of surface water bodies in the EU in good ecological status. In the developing world, it is estimated that up to 70% of industrial waste is dumped untreated into rivers and lakes, leaving many people with no choice but to rely on polluted water supplies.
