What You'll Learn
Excessive algae blooms
The Shenandoah River has been suffering from excessive algae blooms, which have caused fish kills and rendered the river unusable. In 2017, the Shenandoah Riverkeeper and Potomac Riverkeeper Network sued the U.S. Environmental Protection Agency (EPA) over the issue of excessive algae. They argued that the EPA had failed to protect the river and that it suffered from high levels of pollution, including excessive algae blooms. Despite this, the courts ruled against including the Shenandoah River on the state's impaired waters list, as Virginia did not have a water quality standard for algae.
Algal blooms are a sign of an ecosystem out of balance and are fuelled by nutrient pollution from fertilizers and sewage, as well as climate change factors such as extreme weather conditions and warmer water temperatures. In the case of the Shenandoah River, waste runoff from livestock and poultry manure is a significant contributor to the pollution. Excess manure leaks into groundwater and is washed into streams and rivers during rainfall, leading to high levels of phosphorus and other pollutants in the water.
Additionally, cattle herds with direct access to the river have contributed to the problem. While there has been some progress in reducing the number of cattle with direct river access, a significant percentage of farms in the largest agricultural counties in Virginia still fail to fence their cattle out of streams. This allows the animals to deposit fecal bacteria, nitrogen, and phosphorus pollution into the waterways.
The pollution in the Shenandoah River has had a negative impact on recreational activities such as fishing, swimming, and rafting. Despite some improvements in water quality, the river remains unsafe for swimming most of the time. Environmental groups have been advocating for stronger bacteria standards and the posting of swimming advisory signs to warn the public about contaminated areas. They also push for increased funding and efforts to reduce pollution in the river.
To address the issue of excessive algae blooms and improve water quality in the Shenandoah River, several measures have been proposed. These include establishing better systems for collecting and disposing of surplus livestock manure, requiring fertilizer management plans for farms, and imposing pollution limits on agricultural runoff. By implementing these measures and working collaboratively, there is hope for restoring the health and ecological balance of the Shenandoah River.

High levels of E. coli bacteria
The Shenandoah River is a popular destination for many, with beautiful scenery and water sport activities. However, the river has been facing significant pollution issues, with high levels of E. coli bacteria being a primary concern.
E. coli, or Escherichia coli, is a type of bacteria commonly found in the intestines of warm-blooded organisms, including humans and livestock. While some strains of E. coli are harmless, others can cause serious illness, such as diarrhea, abdominal cramps, and kidney failure. High levels of E. coli in the Shenandoah River indicate fecal contamination, which can pose a severe health risk to humans and other organisms that come into contact with the water.
Agricultural runoff is a major contributor to the high levels of E. coli in the river. Livestock and poultry manure contain high levels of E. coli, and when they are not properly managed, they can end up in the water. In 2019, a study by the Environmental Integrity Project (EIP) and the Shenandoah Riverkeeper found that 81% of farms in Augusta and Rockingham, the state's two largest farming counties, failed to fence their cattle out of streams. This allows the animals to defecate directly into the waterways, leading to high levels of E. coli and other bacteria.
In addition to agricultural runoff, sewage and fertilizer use also contribute to the high levels of E. coli. In the past, straight sewage was a significant source of pollution in the river. While this has been reduced, waste runoff from livestock can still contain high levels of E. coli and other bacteria. Fertilizers used in agriculture can also contain bacteria that, when washed into the river, contribute to the high levels of E. coli.
The presence of high levels of E. coli in the Shenandoah River has led to concerns about the safety of swimming and other recreational activities. A report found that 90% of water quality monitoring stations along the river and its tributaries detected E. coli at levels unsafe for human contact between 2014 and 2016. While pollution levels have decreased somewhat since then, the river remains unsafe for swimming and other activities most of the time. Environmental groups have been advocating for better signage and warnings to inform the public about the potential risks.

Pollution from agricultural runoff
The Shenandoah River has been facing pollution issues for many years, with environmental groups tracking algal blooms in the river for over a decade. The river is often unsafe for swimming due to high levels of pollution, including E. coli bacteria. While the pollution has decreased slightly in recent years, it is still unsafe to enter or drink the water in most places.
Agricultural runoff is a significant contributor to the pollution of the Shenandoah River. Livestock waste runoff is a major issue, with manure from the millions of chickens, turkeys, and cows raised in the valley's counties ending up in the river. This waste contains high levels of phosphorus, which leaks into the groundwater and is washed into streams and rivers during rainfall. In addition, cattle herds have direct access to the river, allowing them to deposit fecal bacteria, nitrogen, and phosphorus pollution into the water.
Fencing has been identified as a potential solution to the problem of cattle accessing the river. In 2015, it was reported that 75 cattle herds had direct access to the river, and by 2020, this number had been reduced to about 15. In the same year, the Virginia General Assembly passed a bill requiring cattle operations with 20 or more bovines to exclude the animals from streams with fencing starting in 2026. However, this measure is dependent on the state meeting its Chesapeake Bay pollution reduction goals in 2025 and the availability of funding to help farmers install the fences.
Another source of agricultural runoff is fertilizer use. Excess manure from livestock is often spread on farmland as fertilizer, but the high phosphorus content can leak into the groundwater and be washed into nearby streams. In addition to manure, chemical fertilizers used in agriculture can contribute to nutrient pollution in the river, leading to algal blooms. While some progress has been made in reducing agricultural runoff, it remains a significant challenge in the ongoing efforts to improve the water quality of the Shenandoah River.

Lack of adequate water quality standards
The Shenandoah River is a popular spot for water sports and fishing. However, it is often unsafe for swimming due to high levels of pollution. A report found that 90% of water quality monitoring stations along the river and its tributaries detected fecal bacteria (E. coli) at unsafe levels between 2014 and 2016. While pollution levels have decreased slightly in recent years, the river remains unsafe for swimming and drinking.
One of the main sources of pollution in the Shenandoah River is agricultural runoff, particularly waste runoff from livestock. In 2019, a study found that 81% of farms in Augusta and Rockingham, the state's two largest agricultural counties, failed to fence their cattle out of streams. This allows the animals to deposit fecal bacteria, nitrogen, and phosphorus pollution into the waterways. In addition, the manure from the millions of chickens, turkeys, and cows raised in the valley's counties is often spread on surrounding farmland as fertilizer, but it contains more phosphorus than crops need, leading to excess manure leaking into groundwater and streams.
Environmental groups have filed lawsuits against the EPA, alleging that they have failed to protect the river from excessive algae blooms and pollution. The Shenandoah Riverkeeper and Potomac Riverkeeper Network sued the EPA in 2017, seeking to have the river declared impaired by nuisance filamentous algae. However, the courts ruled against them, stating that Virginia lacked a water quality standard for algae that could trigger such a listing. Despite this setback, the Virginia Department of Environmental Quality (DEQ) has been working to address the issue under pressure from environmental groups.
The DEQ has provided funding for conservation practices and is taking steps to reduce agricultural pollution. However, Virginia has been criticized for not having adequate water quality standards, particularly regarding bacteria levels. Environmental groups have called for stronger bacteria standards and the posting of swimming advisory signs in contaminated areas. While the river meets the old water contact standard during the swimming season, more stringent standards are needed to ensure the safety of those using the river for recreational purposes.
Overall, the lack of adequate water quality standards in Virginia has hindered efforts to protect and restore the Shenandoah River. With high levels of pollution from agricultural runoff and algae blooms, the river remains unsafe for swimming and drinking, despite some improvements in recent years. Stronger water quality standards and enforcement measures are needed to address this issue effectively.
