Radioactive contamination from nuclear waste
The Savannah River, which serves as a primary source of drinking water for over 1.5 million people in Georgia and South Carolina, has been labelled as the third most toxic river in the United States. A report from 2010 revealed that over five million pounds of toxic discharge were released into the river's waterways. The river has also been subjected to damming, dredging, and contamination from industrial waste and radioactive contaminants.
The presence of radioactive isotopes in the environment, such as Cesium-137, uranium, and tritium, poses risks to sediment, fish, deer, soil, and groundwater. The South Carolina Department of Health and Environmental Control has issued fish advisories due to the potential presence of contaminants, but conflicting data between Georgia and South Carolina creates confusion for those fishing in the river.
The effects of radioactive contamination extend beyond the immediate area, as the river's tributaries, creeks, and streams are also impacted. The contamination threatens the health of the ecosystem and the people who rely on the river for their water supply. It is essential to address the issue of radioactive waste and develop comprehensive clean-up plans to minimize the long-term environmental and health risks associated with radioactive contamination in the Savannah River.
To address the issue of radioactive contamination in the Savannah River, several measures have been proposed. It has been recommended that the DOE should stop grouting residual radioactivity in high-level waste tanks and instead focus on recovering buried wastes and highly contaminated soil. Additionally, there have been calls for increased funding for environmental monitoring and a thorough geological investigation to determine the extent of groundwater contamination. By addressing these issues and implementing stricter policies to regulate toxic discharge and waste management, it is possible to mitigate the effects of radioactive contamination and improve the health and safety of the Savannah River and the communities that depend on it.

Contradictory water quality reports from Georgia and South Carolina
The Savannah River serves as the primary source of drinking water for over 1.5 million residents of Georgia and South Carolina. For decades, the Savannah River Site nuclear facility near Aiken, South Carolina, has released dangerous levels of pollutants into the river. The water quality reports from Georgia and South Carolina present contrasting data, creating confusion and uncertainty about the true state of the river's cleanliness.
Georgia's water quality reports indicate that the river is generally safe for consumption. The state addresses common challenges such as hard water, sediment and particles, chemical contaminants, and the presence of iron and manganese. Georgia's reports highlight the treatment processes, potential risks, and safety measures in place to ensure water safety. The Clean Water Act, a federal law, also helps regulate pollutants and maintain water quality for surface waters in Georgia.
In contrast, South Carolina's water quality reports paint a different picture. According to their data, more than 70% of the water basin is contaminated. This contamination could be due to various factors, including mercury, lead, pollution, and runoff. The South Carolina Department of Health and Environmental Control regularly tests and monitors surface water for contaminants near the Savannah River Site. However, the state's data representation method, using single dots to indicate testing locations, differs from Georgia's approach of highlighting the entire river stream with a single color.
The contradictory reports from the two states create challenges for those who rely on the river for fishing and other activities. Jacob Oblander, Outreach Coordinator for Savannah Riverkeeper, points out the dilemma this poses: "It creates an issue if there’s a fish advisory for a section of the river and someone is out fishing, they don’t know what state to listen to.” The discrepancy in the data presentation methods further complicates the matter, making it difficult to determine the accurate level of contamination in specific areas of the river.
The conflicting reports from Georgia and South Carolina underscore the need for improved coordination and standardized data representation to ensure the public's safety and well-being. It also highlights the importance of addressing the pollution issues affecting the Savannah River to protect the health and livelihoods of the communities that depend on it.

Toxic discharge from companies and cities
The Savannah River has been described as the third most toxic river in the United States. In 2010, more than 5 million pounds of toxic discharge were released into its waterways, with Georgia ranked as the eighth worst state for toxic chemical dumping in 2012. The river serves as the primary source of drinking water for over 1.5 million people in Georgia and South Carolina. This has led to concerns about the potential health risks of consuming contaminated water.
The contamination of the Savannah River can be attributed to various factors, including industrial activities, nuclear waste, and agricultural runoff. The river passes through a diverse industrial complex, the Savannah River Site (SRS), where multiple waste streams are produced and disposed of. This has resulted in the presence of radioactive isotopes such as Cesium-137, uranium, and tritium in the environment, including sediment, fish, deer, soil, and groundwater. The SRS also utilised chlorinated solvents, leading to groundwater and soil contamination with trichloroethylene. Coal-burning plants have further contributed to the pollution, leaving behind coal ash basins and landfills.
The DOE has been criticised for its unsafe management of high-level nuclear waste. By grouting residual radioactivity in tanks, large amounts of radioactivity are left near the river, posing risks of groundwater contamination. Inadequate cleanup plans, such as capping shallow dumps and seepage basins, fall short of providing long-term protection for the region's water resources. The subsistence fishermen who rely on the river for their livelihood and consume fish in excess of the recommended limits are particularly vulnerable to the health risks associated with contaminated water.
Agricultural runoff also contributes to the toxic discharge in the Savannah River. Fertilisers and pesticides used in agriculture can contain harmful chemicals that, when washed into the river, pose risks to aquatic life and contribute to the overall degradation of water quality. Additionally, the river is utilised by manufacturers to dilute their waste streams, further adding to the pollution.
The conflicting water quality reports from Georgia and South Carolina add to the complexity of the situation. While Georgia indicates certain sections of the river as clean, South Carolina's data suggests otherwise. This discrepancy creates confusion and challenges in addressing the pollution problem effectively, as it impacts the ability to make informed decisions and take necessary precautions when utilising the river's resources.

Mercury, lead, and other pollutants
Mercury and lead are particularly harmful contaminants due to their toxicity and persistence in the environment. Mercury, a heavy metal, can accumulate in fish and other aquatic organisms, leading to health risks for humans who consume them. Lead, another toxic metal, can leach into drinking water supplies, posing dangers to human health, especially in children.
The presence of these contaminants in the Savannah River can be attributed to various sources, including industrial activities, agricultural runoff, and nuclear waste. The river's basin is home to a diverse industrial complex, including the Savannah River Site nuclear facility, which has been responsible for releasing dangerous levels of tritium and other radioactive isotopes into the river. In addition, coal-burning plants and manufacturing processes contribute to the pollution of the river with coal ash and chemical waste.
Agricultural activities also play a role in the contamination of the river. Runoff from farms can carry pesticides, fertilizers, and other chemicals into the river, leading to increased nutrient levels and algal blooms, which deplete oxygen levels in the water. This, in turn, can create dead zones where aquatic life cannot survive.
Furthermore, the improper management of nuclear waste has been a significant concern for the Savannah River. The Department of Energy (DOE) has been criticized for its practice of grouting residual radioactivity in high-level waste tanks, leaving large amounts of radioactivity near the river. This has led to calls for urgent recovery of buried wastes and contaminated soil to minimize long-term water pollution.
The contamination of the Savannah River has led to efforts to improve water quality and ensure safe drinking water for the communities that rely on it. While the river has a certain level of self-cleaning capacity, it is crucial to address the sources of pollution and implement measures to reduce toxic discharge. This includes advocating for policies that require industries to switch to safer chemicals and ensuring that the Clean Water Act is applied to all relevant waterways.

Contaminated drinking water sources
The Savannah River is a primary source of drinking water for over 1.4 million people, including residents of Chatham County in Georgia and Beaufort and Jasper Counties in South Carolina. However, the river faces significant pollution issues, with more than 5 million pounds of toxic discharge released into its waterways in 2010, and over 10 million pounds of toxic chemicals dumped into Georgia's waterways in 2012.
The river has been described as the third most toxic in the United States, with radioactive contamination being a particular concern. The Savannah River Site nuclear facility near Aiken, South Carolina, has released dangerous levels of tritium and other pollutants. The DOE has been criticized for its inadequate clean-up plans and unsafe waste management practices, leaving large amounts of residual radioactivity in tanks near the river.
In addition to radioactive contamination, the river is also affected by chemical pollution. Industries located along the river use its water to dilute manufacturing waste streams, contributing to the presence of toxic chemicals. Environment Georgia has recommended policies to address this issue, including requiring industries to switch to safer chemicals and ensuring that the Clean Water Act is applied to all waterways.
The impact of pollution on the Savannah River is compounded by the phenomenon of "assimilative capacity," which refers to the finite amount of pollution a river can handle before its health is severely compromised. With the upstream users of the river contributing significantly to its pollution load, the downstream communities are facing the consequences, including issues with water quality and recreational use.
Despite the concerning levels of contamination, some reassurance can be found in the water treatment processes. The water obtained from the Savannah River is treated and safe to drink, according to spokespeople in both South Carolina and Savannah. Daily tests are conducted, consistently exceeding federal requirements, ensuring that drinking water sources are closely monitored for any potential health risks.
