What You'll Learn
Sewage and wastewater treatment
The Chattahoochee River has faced several instances of sewage spills and wastewater treatment issues, which have raised concerns about pollution and its impact on the environment and public health. One notable incident occurred in 2023 when a malfunction at the Big Creek Wastewater Treatment Plant in Fulton County resulted in the release of untreated or partially treated sewage into the river. This incident led to elevated E. coli levels, making the water unsafe and unhealthy. As a result, approximately 11 to 15 miles of the river were closed to the public, and environmental concerns were raised.
Wastewater treatment plants employ various physical, chemical, and biological processes to treat sewage before it is discharged into the river. These processes aim to remove contaminants, organic matter, and harmful bacteria, ensuring that the treated wastewater meets the required standards for safe release into the environment. However, when treatment plants malfunction or are overwhelmed, untreated or partially treated sewage can find its way into the river, posing significant risks. High levels of bacteria, such as E. coli, can indicate the presence of pathogens and pose health risks, especially to vulnerable populations.
To address sewage and wastewater treatment challenges, it is essential to invest in infrastructure upgrades and maintenance. This includes repairing and replacing ageing sewer pipes, which can crack and leak, contaminating nearby waterways. Additionally, implementing stricter regulations and enforcing compliance with the Clean Water Act can help hold polluters accountable and deter illegal discharges of pollutants. Community engagement and education also play vital roles in fostering a collective sense of responsibility for the river's health and encouraging sustainable practices upstream to reduce the impact on downstream neighbours.
The Chattahoochee Riverkeeper (CRK) plays a crucial role in monitoring water quality, advocating for the river's protection, and holding responsible parties accountable. Through routine water sampling and testing, CRK has identified instances of high bacteria levels and illegal discharges, taking legal action when necessary. Their efforts, alongside those of park rangers, local governments, and environmental officials, are vital in safeguarding the Chattahoochee River and ensuring the health and safety of the communities and ecosystems that depend on it.

Stormwater and urban runoff
The runoff picks up bacteria, oil, grease, heavy metals, and trash as it makes its way towards the Chattahoochee. These substances have a detrimental effect on the river's ecosystem. Oil and grease attach to sediment, are ingested by aquatic organisms, and become harmful to the entire food chain. Phosphorous and nitrogen from sources such as golf courses, lawns, and parking lots can also cause algal blooms and excessive aquatic weed growth, reducing sunlight and oxygen for other aquatic life and decreasing wildlife habitats.
In addition, runoff from chicken, hog, and cattle farms raises fecal coliform bacteria levels in the river. When the river reaches Atlanta, land clearance and rapid development further increase sedimentation and water temperatures. Billions of gallons of stormwater that would have once soaked into the ground now rush into creeks and streams, causing degradation to the river.
The impact of stormwater and urban runoff on the Chattahoochee River has been recognised, and efforts have been made to address the issue. Atlanta has implemented the 'Green Streets and Clean Streams' project, which uses "green infrastructure" to manage rainwater and restore the natural flow of water. This project includes the installation of "stormwater planters" that direct stormwater away from streets and into structures filled with rocks, engineered soils, trees, and other native vegetation. These planters help to reduce the amount of polluted stormwater flowing into the river and its creeks.

Trash and littering
The Chattahoochee River is a vital source of drinking water for the people of Atlanta, providing 70% of the city's supply. However, it is also heavily polluted, and this has been a long-standing issue. One of the major causes of pollution in the river is trash and littering.
The problem of trash in the Chattahoochee River is not new, and efforts have been made to address it. The nonprofit organisation Chattahoochee Riverkeeper has been actively involved in patrolling, protecting, and monitoring the river. In 2017, around 700 volunteers participated in the annual "Sweep the Hooch" event, where 16.2 tons of trash were removed from a 70-mile stretch of the river. This was an increase from the previous year, where 15.6 tons of trash were collected. Unfortunately, the amount of trash in the river continues to increase annually, and it is up to individuals to dispose of their waste properly and not litter.
In addition to volunteer efforts, organisations like Rivers Alive are dedicated to cleaning up the Chattahoochee River. They provide opportunities for individuals and groups to join or organise cleanups, making a significant impact by removing trash from the river. These collective efforts are crucial in mitigating the effects of trash and littering on the river's health.
While these cleanup initiatives are making a difference, it is essential to address the root cause of the problem. Public education and awareness about the impact of littering on the river are vital. By understanding the consequences of their actions, individuals can be encouraged to take responsibility for their waste and dispose of it properly. Additionally, stricter enforcement of laws and regulations regarding waste management and pollution can help deter littering and hold accountable those who violate clean water laws.

Industrial pollution
The Chattahoochee River, which flows 436 miles from Georgia to the Florida border, has faced significant pollution threats over the years, including industrial pollution. The river provides drinking water to millions of people in metro Atlanta, but industrial activities have contributed to the contamination of its waters.
One notable incident of industrial pollution in the Chattahoochee River occurred in July 2023 when the Big Creek wastewater treatment plant in Fulton County malfunctioned. For almost three weeks, approximately 13 million gallons per day of partially treated sewage and high levels of E. coli bacteria were released into the river. This incident not only posed a risk to human health but also to the river ecosystem.
In addition to wastewater treatment plant failures, industrial sites along the river have also been identified as sources of pollution. Pipes from these sites have been observed discharging directly into the river. The RM Clayton plant, for example, has been reported to have 69 "effluent limit violations" by the state Environmental Protection Division. These violations indicate instances where the treated wastewater discharged into the river exceeded permissible levels of contaminants.
Efforts are being made to protect the Chattahoochee River from industrial pollution. The Chattahoochee Riverkeeper, an organisation dedicated to patrolling and protecting the river, has been advocating for stricter enforcement of clean water laws and larger penalties for polluters. They are asking the Environmental Protection Division to hold industrial facilities and wastewater treatment plants accountable for their impact on the river's health. Additionally, the National Park Service took the unprecedented step of shutting down 15 miles of the river in response to the plant malfunction, demonstrating the seriousness of the pollution issue.

Conservation and public awareness
The Chattahoochee River has faced a long history of pollution, with sewage spills, stormwater runoff, and toxic chemicals threatening aquatic life and limiting recreation. Conservation efforts and public awareness campaigns have been crucial in addressing these issues and improving water quality.
One of the primary challenges has been the antiquated sewer system in Atlanta, which has resulted in cracked and leaky pipes, as well as overburdened combined sewer overflows (CSOs). These issues have contaminated the city's waterways and led to significant penalties for Atlanta since the 1990s. In response, organizations like the Upper Chattahoochee Riverkeeper (UCR), now known as Chattahoochee Riverkeeper, have played a pivotal role in advocating for cleaner water. UCR successfully built a coalition of downstream stakeholders, including local governments and environmental organizations, to hold Atlanta accountable for violations of the Clean Water Act. This resulted in Atlanta facing substantial fines and being mandated to address its sewage treatment issues.
Public awareness and involvement have been instrumental in driving change. Increased awareness about pollution has helped, according to Jerry Hightower, a park ranger with over 35 years of experience in the recreation area. The Chattahoochee Riverkeeper organization has actively engaged the public, encouraging them to contact Georgia's Environmental Protection Division to hold polluters accountable and enforce the Clean Water Act. Their efforts have included routine water quality monitoring, which detected dangerously high E. coli bacteria levels in the river, traced to the Big Creek wastewater treatment plant.
Additionally, conservation is recognized as a critical aspect of protecting the river. The Metropolitan River Protection Act, passed in 1973, set strict rules on new development within 2,000 feet of the river. However, despite these efforts, the river continues to face threats from stormwater runoff, climate change, and pollution from various sources, including lawn chemicals and improperly disposed-of pet waste.
Moving forward, continued public engagement and support for conservation initiatives are vital to ensuring the long-term health of the Chattahoochee River. While progress has been made, the river remains vulnerable to pollution, and the collective actions of the public and stakeholders will be pivotal in safeguarding this valuable resource.
