Water Pollution's Historical Start: When Did It Begin?

Water pollution has been an issue for centuries, with humans unknowingly contaminating drinking water sources with raw sewage, leading to diseases such as cholera and typhoid. However, it was not until the Industrial Revolution in the mid-19th century that water pollution became a widespread and pressing issue. The rapid industrialization and urbanization of this period led to new sources of pollution, with waste from factories and industries contaminating water sources. This, coupled with a lack of legislation and public concern, resulted in waterways becoming filthy and disregarded. It was not until the mid-1940s, when outbreaks of waterborne diseases and the degradation of fishing and recreational waters occurred, that there was a push for better water pollution control. This led to the enactment of the Federal Water Pollution Control Act of 1948, the first major law to address water pollution in the United States. However, it was the environmental movement of the 1960s and the Cuyahoga River fires of 1969 that truly brought water pollution to the forefront of public attention and spurred the creation of the Clean Water Act in 1972.

The Industrial Revolution's impact on water pollution

Water pollution has been an issue for centuries, with humans unknowingly contaminating drinking water sources with raw sewage as early as the 1800s, leading to diseases like cholera and typhoid. However, the Industrial Revolution significantly exacerbated water pollution, introducing new sources of pollution and intensifying existing ones.

During the Industrial Revolution, factories began releasing pollutants directly into rivers and streams, causing severe contamination. The mix of pollutants included industrial chemicals, wastes, and by-products such as sulfuric acid, soda ash, muriatic acid, limes, dyes, wood pulp, and animal byproducts. This led to the degradation of freshwater sources and negatively impacted the biota supported by these waters. For example, in 1897, a report to the Royal Commission on River Pollution detailed the gross industrial contamination of the Tawe River in Wales, polluted by various industrial sources.

The issue of industrial water pollution was not limited to a single river or region. In the United States, the Northeast region faced similar challenges, with industrial mills contaminating waters with sulfuric acid, soda ash, and other harmful substances. As cities became more populated towards the end of the 19th century, industrialized cities across Europe and the United States experienced a new kind of pollution: waste from industries and factories. The rapid population growth and industrial development during this period further contributed to the pollution problem.

The impact of the Industrial Revolution on water pollution extended beyond the immediate contamination of rivers and streams. In the mid-1940s, outbreaks of water-borne diseases, degradation of fishing and recreational waters, and population and industrial growth prompted a new appraisal of water pollution control. Cities had to implement large-capital improvement programs to address pollution control, and industries struggled with varying interpretations of laws and overlapping regulatory authority. California, for example, faced challenges with limited water resources and enacted the Dickey Water Pollution Act in 1949 to maximize water quality and economic use through regional control boards.

While efforts to control water pollution have been made since the Industrial Revolution, it remains a persistent issue. Even with legislative victories like the Clean Water Act of 1972 in the United States, which provided funding for sewage treatment plants and set limits on industrial discharges, water pollution continues to affect our planet. Today, industrial waste is still dumped untreated into water bodies, particularly in developing regions, and many industrial and municipal facilities exceed permitted pollution levels. As a result, water pollution remains a global challenge, with ongoing efforts to address it through legislation, technological advancements, and environmental awareness.

California's water pollution crisis

Water pollution has been a concern for centuries, with humans unknowingly contaminating drinking water sources with raw sewage, leading to diseases such as cholera and typhoid. The Industrial Revolution of the 19th century introduced new sources of water pollution, and by the mid-20th century, countries around the world were feeling the effects.

California, a state that declares water a "human right," is facing a water contamination crisis. Almost one million California residents have contaminated water supplies, and the issue is exacerbated by economic inequality, with low-income communities hit the hardest. The state's water resources are under threat from various factors, including dangerous heatwaves, extreme droughts, floods, and increasing wildfire risk.

The roots of California's water crisis can be traced back to the mid-1940s, when outbreaks of waterborne diseases, degradation of fishing and recreational waters, rapid wartime industrial development, and population growth highlighted the need for better water pollution control. In 1949, the California Assembly Committee on Water Pollution acknowledged that existing laws and procedures were inadequate, and the state enacted the Dickey Water Pollution Act, creating a State Water Pollution Control Board.

Despite these efforts, California continues to struggle with water pollution, and in 2024, residents named climate change, wildfires, and water supply and drought as the most pressing environmental issues facing the state. The state's water systems are failing, with nearly 400 communities in California facing issues with water quality and accessibility. The situation is made worse by aging infrastructure and underfunding, with local, state, and federal agencies stretched thin in their response to the urgent issues.

To address the crisis, California is exploring "adaptation pathways," which involve developing flexible and responsive plans to protect residents, the environment, and the economy. Improving infrastructure and emergency preparedness will be crucial, and affected communities must be included in decision-making processes. While the challenges are significant, California has shown great ingenuity in the face of adversity, and there is hope that proactive decisions and partnerships can lead to better outcomes.

Sewage systems and their development

The development of sewage systems has a long history, with the earliest sanitation systems being built in prehistoric Iran around 3000 to 2000 BCE. These ancient systems used gently sloping underground channels called "qanats" to transport water, and "ab anbars", or traditional reservoirs, for water supply and cooling. The Indus Valley Civilisation in East Asia, dating back to 3300 BCE, featured homes made of mud or mud bricks, with evidence suggesting the use of clay bricks for early sewage treatment.

Fast forward to the Neolithic era, around 12,000 years ago, and humans dug permanent wells for water use, marking the beginning of wastewater systems. Around 3000 BCE, in Skara Brae, Scotland, evidence was found of small rooms in homes that may have served as primitive toilets, connected to an indoor, tree bark-lined, stone freshwater and wastewater system.

Moving into the 17th to 19th centuries, the Enlightenment Era brought advancements in sewage treatment, particularly in Rome and Istanbul, which developed networks of sewers that are still in use today. However, many European countries lagged in adopting these innovations.

The Industrial Revolution, with its heavy industrialisation and urbanisation, exacerbated sanitary conditions. This prompted the development of modern sewerage systems in the mid-19th century. British civil engineer Baldwin Latham contributed significantly to the rationalisation of sewerage and house drainage systems, pioneering sanitary engineering. He introduced the concept of oval sewage pipes to enhance drainage and prevent sludge deposition and flooding.

In the United States, Chicago built the first major sewage system in the mid-1850s to treat wastewater, with other US cities following suit. The late 19th and early 20th centuries saw many cities construct extensive sewer systems to control disease outbreaks, such as typhoid and cholera, caused by contaminated water supplies.

By the early 20th century, most cities in the Western world had implemented more effective sewage treatment systems. The discovery of the activated sludge treatment process in 1912 by scientists at the University of Manchester further improved wastewater treatment.

In California, the limited water resources and increasing population and industrial growth prompted the enactment of the Dickey Water Pollution Act in 1949. This led to the establishment of Regional Water Pollution Control Boards to oversee and enforce pollution abatement programs.

Despite these advancements, water pollution continued to be a pressing issue, with the Cuyahoga River in Ohio catching fire several times between 1936 and 1969 due to debris and oil accumulation. This incident, along with increasing environmental awareness, spurred grassroots activism and legislative changes, including the Federal Water Pollution Control Act (commonly known as the Clean Water Act) in 1972.

Waterborne diseases and pollution

Waterborne diseases and water pollution have been linked to human health risks for centuries. As early as the 1800s, people began to understand the connection between unsanitary living conditions, water contamination, and disease epidemics. This realisation prompted cities to implement measures to control waste and improve sanitation. Chicago, for instance, constructed the first significant sewage system in the United States in the mid-1850s to treat wastewater, with other cities following suit.

The Industrial Revolution of the mid-19th century brought new sources of water pollution, with industrialised cities in Europe and the United States facing waste from factories and industries. By the mid-1940s, water-borne disease outbreaks, declining fishing and recreational waters, and rapid wartime industrial development and population growth, highlighted the need for improved water pollution control. California, in particular, recognised the urgency of the situation, as population and industrial growth threatened to exhaust its limited water supplies.

In 1949, California enacted the Dickey Water Pollution Act, establishing a State Water Pollution Control Board to address the state's unique regional challenges, including precipitation, topography, and population density. This marked a significant shift in California's approach to water pollution control and set a precedent for other regions.

Despite these efforts, water pollution continued to increase well into the 20th century. The Cuyahoga River in Cleveland, Ohio, became a notorious example, catching fire several times between 1936 and 1969 due to debris and oil accumulation. The final blaze in 1969 sparked widespread environmental awareness and activism, leading to the creation of the Federal Water Pollution Control Act (commonly known as the Clean Water Act) in 1972.

Today, waterborne diseases continue to afflict hundreds of millions of people, particularly those in developing countries with limited access to safe and clean water. Diarrhoea, cholera, typhoid, dysentery, hepatitis A, and polio are among the most common waterborne illnesses, causing preventable health risks and even deaths, especially among children.

Environmental activism and legislation

The emergence of environmental activism and legislation in the 20th century was a response to the growing problem of water and air pollution. The Industrial Revolution of the 19th century introduced new sources of pollution, and by the middle of the 20th century, the effects were being felt worldwide.

In the 1940s, outbreaks of waterborne diseases, degradation of fishing and recreational waters, and rapid industrial development and population growth prompted a re-evaluation of water pollution control. The Federal Water Pollution Control Act of 1948 was the first major US law to address water pollution. However, it wasn't until the 1960s that an environmental movement began to emerge, seeking to address the tide of pollutants flowing into the planet's ecosystems.

In 1963, Stewart Udall, the Secretary of the Interior, published "The Quiet Crisis", an early call to arms on environmental pollution. That same year, the Clear Air Act was passed, allocating $95 million for the study and cleanup of air and water pollution and giving the federal government the authority to regulate emissions standards. In 1965, the Water Quality Act further enhanced federal control over water quality.

The 1960s also saw the emergence of grassroots activism, with the first Earth Day taking place in 1970, where 20 million Americans protested against environmental pollution. This activism resulted in a wave of federal legislation, including the Clean Water Act of 1972, which established nationwide standards for industrial wastewater discharge and made the regulation of hazardous pollutants a federal responsibility. The Clean Water Act was passed despite opposition from industry and the White House, thanks to the efforts of environmental activists.

The Clean Water Act was a landmark piece of legislation that provided funding to improve sewage treatment plants and set limits on the discharge of pollutants into the water. It also established the Environmental Protection Agency (EPA), tasked with enforcing regulations and coordinating federal policy on environmental quality. The EPA has since played a crucial role in maintaining and improving water quality, working with states to implement water quality criteria and pollution control programs.
