Study Notes

Importance of Clean Water

Water is the most important substance for human life, essential for industry, daily life, recreation, and other essential activities.
Water's ability to dissolve and carry various substances makes it the universal solvent.
Water's high specific heat makes it an ideal cooling agent for mechanical and industrial devices.
However, dirty water can be dangerous, as it can carry toxic chemicals, diseases, and parasites.

Establishment of the Environmental Protection Agency (EPA)

By the mid-20th century, American industry had grown, leading to environmental pollution and public awareness of its impact.
In 1969, the Cuyahoga River caught on fire due to pollution, leading to increased environmental concerns.
In 1970, President Richard Nixon proposed the formation of the EPA, which was created to consolidate environmental regulations and conservation activity.

The Clean Water Act of 1972

The CWA was established to regulate pollutant discharges into waterways, requiring permits for point source pollution.
A point source is a discrete conveyance, such as a pipe or ditch, used for discharging waste.
The CWA defines "waters of the United States" broadly, including navigable waters, tributaries, interstate waters, and more.
Each state issues permits that comply with a minimum federal standard, restricting pollutant releases.

Effects of the Clean Water Act

The CWA led to improved water quality and soil erosion, with federal funds provided for water-treatment plants.
Fish from the Cuyahoga River was declared safe to eat in 2019, a significant improvement.

The Safe Drinking Water Act of 1974

The SDWA aimed to ensure safe drinking water by regulating pollutants, microorganisms, and contaminants not covered by the CWA.
The SDWA empowered the EPA to set standards on pollutants affecting drinking water, focusing on water treatment and removal of pollutants.
Later amendments regulated water sources, preventing pollutants from contacting water supplies at their source.

Difference Between the Clean Water Act and Safe Drinking Water Act

The CWA limits pollution from point sources, reducing pollutants discharged from factories and sewage treatment facilities.
The SDWA primarily exists to protect drinking water supplies, regulating pollutants regardless of their source.
The CWA is administered by the EPA, while the SDWA divides power between federal, state, and local agencies.
