The Clean Water Act (CWA) is a major piece of environmental legislation in the United States aimed at ensuring the quality of the nation’s waters.

Understanding The Clean Water Act

The Clean Water Act plays a crucial role in protecting and maintaining the quality of water resources in the United States, addressing both point and non-point source pollution through regulatory frameworks and enforcement mechanisms.

Purpose:  

The primary goal of the Clean Water Act is to restore and maintain the chemical, physical, and biological integrity of the nation’s waters.

Regulatory Authority:  

The Environmental Protection Agency (EPA) is the federal agency responsible for enforcing the Clean Water Act.

Point Source Pollution:  

The CWA regulates point source pollution, which refers to pollutants discharged into waters from specific, identifiable sources such as factories or wastewater treatment plants.

National Pollutant Discharge Elimination System (NPDES):

The NPDES program is a key component of the CWA. It requires permits for point source discharges into waters of the United States.

Water Quality Standards:  

The CWA establishes water quality standards for surface waters. These standards set specific criteria for different pollutants to protect human health, aquatic life, and the environment.

What Does The Clean Water Act Do?

The Clean Water Act (CWA) is a comprehensive environmental statute in the United States that addresses water pollution and aims to maintain and improve the quality of the nation’s waters.

• Regulation of Point Source Pollution:  

The CWA regulates point source pollution, which refers to pollutants discharged into waters from specific, identifiable sources. It requires permits for such discharges through the National Pollutant Discharge Elimination System (NPDES).

• National Pollutant Discharge Elimination System (NPDES):  

Under NPDES, permits are issued to control the discharge of pollutants from point sources into navigable waters. These permits set limits on the types and amounts of pollutants that can be released.

• Water Quality Standards:  

The CWA establishes water quality standards for surface waters. These standards set specific criteria for different pollutants to ensure that water bodies are suitable for various uses, including drinking water, swimming, and the protection of aquatic life.

• Total Maximum Daily Load (TMDL):  

TMDL is a regulatory tool used to assess and manage water quality. It identifies the maximum amount of a pollutant a water body can receive while still meeting water quality standards. TMDLs allocate pollutant loads among different sources.

• Non-Point Source Pollution Control:  

While the CWA primarily focuses on point source pollution, it also addresses non-point source pollution, which comes from diffuse sources like agricultural runoff and urban stormwater. Various programs and provisions aim to control and manage non-point source pollution.

Why Is The Clean Water Act Needed?

The Clean Water Act (CWA) is needed for several critical reasons, all of which revolve around protecting and preserving the quality of the nation’s water resources.

Public Health Protection:  

Ensuring clean water is essential for safeguarding public health. Contaminated water can carry harmful pathogens and pollutants that pose risks to human health. The CWA establishes standards and regulations to prevent waterborne diseases and protect the safety of drinking water.

Environmental Conservation:  

The CWA aims to protect and restore the chemical, physical, and biological integrity of water bodies, including rivers, lakes, and coastal waters. This focus on environmental conservation helps sustain diverse ecosystems, including fish and wildlife habitats.

Safe Recreational Use:  

Many water bodies serve as recreational areas for swimming, fishing, and boating. The CWA sets water quality standards to ensure that these activities can be enjoyed safely without exposure to harmful pollutants.

Benefits Of The Clean Water Act.

The Clean Water Act (CWA) has had numerous positive impacts on water quality, public health, ecosystems, and the economy since its enactment in 1972.

Improved Water Quality:  

The CWA has led to significant improvements in water quality across the United States. By regulating point source pollution and establishing water quality standards, the Act has helped reduce the discharge of harmful pollutants into rivers, lakes, and other water bodies.

Safe Drinking Water:  

The CWA includes provisions to protect sources of drinking water. By regulating industrial discharges and setting water quality standards, the Act contributes to the provision of safe and clean drinking water for communities.

Reduced Point Source Pollution:  

The National Pollutant Discharge Elimination System (NPDES) under the CWA has been successful in controlling and reducing point source pollution from industrial and municipal facilities. Permits issued under NPDES set limits on pollutant discharges, preventing the degradation of water quality.

Wetlands Preservation:  

The CWA includes provisions to protect wetlands, which are crucial for maintaining biodiversity, providing habitat for wildlife, and offering natural flood control. The Act has helped prevent the destruction of wetlands through permitting and regulatory measures.

Prevention of Oil Spills:  

The CWA includes provisions to regulate oil discharges into navigable waters. This has contributed to the prevention and response to oil spills, protecting aquatic ecosystems and coastal areas.

5 Clean Water Act Success Stories

Here are a few Clean Water Act success stories that you need to know about.

Monterey Bay  

“Despite being known as the ‘Serengeti of the Sea,’ for its diversity of wildlife, California’s Monterey Bay has battled a number of environmental health hazards. Before the Clean Water Act, individual communities had their own sewage treatment plants, often discharging sparsely treated wastewater as little as 300 feet offshore.”

“The passage of the Clean Water Act catalyzed the formation of Monterey One Water, a centralized agency for water supply and sanitation that vastly elevated wastewater quality standards. The Clean Water Act also provided funding to conserve land upstream and prevent runoff into the Bay’s many freshwater tributes.”

“Thanks to the improved state of Monterey Bay, Monterey County welcomed 4.6 million visitors in the 2018-2019 fiscal year, generating $2.98 billion in visitor spending and employing over 25,000 people in the tourism industry.”

Cuyahoga River  

“In 1969, Cleveland’s Cuyahoga River apocalyptically caught on fire for the thirteenth time, cementing the River’s status as one of the most polluted waterways in America. The incident ignited an outrage from environmentalists across the country, and the river became a clean-up priority with the subsequent Clean Water Act.”

“The Cuyahoga River has made great strides since then due to sewage treatment plant grants and more stringent permitting systems brought forth by the Clean Water Act. In 1967, not a single fish of more than 70 species could be found in its waters, and in 2019, the Ohio EPA declared that these fish were safe to eat.”

“The Cuyahoga River has now been designated as an Ohio Scenic River, an American Heritage River, and an Ohio Water Trail, which encourages recreational activity to return to the formerly hazardous river.”

Bristol Bay   

“Bristol Bay’s sprawling watershed of streams, rivers, wetlands, and tundra houses one of the most productive marine ecosystems in the world. Within this Alaskan ecosystem lies the world’s sockeye salmon, supporting 13,000 jobs, and creating $1.5 billion in economic activity.”

“Bristol Bay is the location of the proposed Pebble Mine, an open pit gold and copper mine that would permanently destroy 2,200 acres of wetlands and waters and 105 miles of streams. Tribal leaders and conservation groups have long advocated for the EPA to exercise its veto power endowed by section 404c of the Clean Water Act.”

“In May 2022, the EPA issued a draft proposal to use its Clean Water Act veto to permanently block the mine, with a final determined expected by the end of January 2023.”

Potomac River  

“Before the Clean Water Act was passed, 240 million gallons of waste flowed into the Potomac River daily. The river was considered a severe health hazard, enough so that anyone who fell into it was advised to get a tetanus shot.”

“The Clean Water Act’s limits on sewage and other pollutants, coupled with regional cooperative efforts and improvements at the Blue Plains wastewater facility in Southwest DC, greatly improved ater quality.”

“Less than five years after the Clean Water Act was passed, there was a noticeable lack of blue-green algae that had covered the upper estuary a decade earlier, and largemouth bass had returned to the river.”

“More recently, the D.C. government has put forth plans to utilize Clean Water Act grant funding to replace its outdated sewage and stormwater system, a project estimated to reduce nitrogen discharge to Chesapeake Bay by one million pounds annually.”

Des Plaines River  

In the early 1960s, “it was hard to find any fish at all in Illois’ Des Plaines River; between 1959 and 1964, common carp and goldfish, both invasive species, constituted 97% of the river’s catch.”

“Over the past fifty years, the Des Plaines River has transformed from a degraded stream to a healthy urban fishery thanks to improvements from the Clean Water Act.”

“The Act allowed Chicago to form the Tunnel and Reservoir, a project that will capture nearly 20 billion gallons of sewage and urban runoff during stroms once complete.”“In 2018, just one year after a large storage reservoir became functional, the amount of fish in the Des Plaines nearly doubled. This increase comprised socioeconomically valuable sport fish, with the proportion of sport fish rising from less than 1% between 1959-1964 to 69% between 2010-2013.”
