Cattle And The Clean Water Crisis In Shenandoah Valley

The Shenandoah Valley, known for its cultural heritage and natural beauty, is home to a large livestock and poultry industry. The runoff from manure produced by nearly 200 million chickens, turkeys, and cows ends up in the Shenandoah River, causing significant water pollution. This has led to concerns about the impact on the region's recreation and economy, as well as public health risks. While efforts have been made to address the issue, such as increased funding for farmers to fence off herds from waterways, the valley's waters continue to face the challenge of bacterial contamination and excessive nutrient pollution, primarily driven by agricultural practices in the area.

Excess cattle manure leaks pollutants into the groundwater

The Shenandoah Valley is known for its cultural heritage and natural beauty. However, the valley is also home to a thriving livestock and poultry industry, with nearly 528,000 cows, 160 million chickens, and 16 million turkeys raised annually in Augusta, Page, Shenandoah, and Rockingham counties. This high concentration of livestock operations has led to a significant pollution problem in the valley's waterways.

The main issue is the excess manure produced by these animals, which contains high levels of phosphorus, nitrogen, and bacteria. While manure is often spread on surrounding farmland as fertilizer, it contains more phosphorus than crops need, leading to a buildup of pollutants in the soil. Eventually, this excess manure leaks into the groundwater and is washed into streams and rivers during rainfall, causing water pollution.

The pollution from cattle manure has been linked to unsafe levels of E. coli bacteria and other fecal bacteria in the Shenandoah River and its tributaries. In 2014-2016, E. coli bacteria concentrations exceeded the state's standards for safe water contact recreation at 91% of state monitoring locations in the Shenandoah River system. The situation has improved slightly in recent years, with 40% of monitoring sites in 2023 exceeding the EPA's recommendations for swimming due to E. coli levels.

The excess manure also contributes to the growth of algae in the water. Phosphorus acts as a plant food, fueling the growth of algae blooms that suck oxygen from the water and create an environment where fish and other marine organisms cannot survive. This has had a negative impact on the fishing industry in the valley and has also discouraged river-based recreation and tourism due to the unpleasant appearance and smell of the algae-covered water.

To address the issue of cattle manure pollution, Virginia passed legislation in 2020 to provide farmers with funding to fence herds of cattle out of streams, with a deadline of 2025 for completing the process. This exclusionary fencing is important for protecting public health, the health of the river ecosystem, and the local economy dependent on recreation and tourism. However, progress has been slow, and some farmers are seeking to delay the deadline to 2030, which could worsen the pollution problem in the Shenandoah Valley.

High levels of E. coli bacteria

The Shenandoah Valley is known for its cultural heritage and natural beauty. However, it also has a thriving livestock and poultry industry, with nearly 200 million chickens, turkeys, and cows. This has resulted in a significant pollution problem in the Shenandoah River and its tributaries.

One of the main issues is the high levels of E. coli bacteria found in the water. In 2021, 60% of monitoring sites along the Shenandoah Valley and its tributaries had levels of E. coli above the EPA's recommendations for swimming. This improved slightly in 2022, with 40% of monitoring sites having levels of E. coli above the recommended level. However, this still presents a health risk to those using the river for recreation or drinking water.

The primary source of the E. coli bacteria is believed to be the manure from the livestock and poultry industries. The manure is often spread on surrounding farmland as fertilizer, but it contains high levels of phosphorus and other pollutants. When it rains, the excess manure is washed into the streams and rivers, contaminating the water. In addition, many farms in the area lack proper streamside fencing, allowing cattle to wade and defecate in the rivers, further contributing to the bacteria levels.

To address this issue, Virginia passed legislation in 2020 providing farmers with funding to install fencing to keep cattle out of streams. The state has also approved funding for farm pollution-control "best management practices" in 2023 and 2024. However, progress has been slow, and some farmers have requested an extension of the deadline for completing the fencing. Environmental advocates argue that any delay will only worsen the problem and that the state should take more urgent action to protect the health of the river and the public.

Lack of streamside fencing on farms with cattle

The Shenandoah Valley, known for its cultural heritage and natural beauty, is home to a thriving livestock and poultry industry. The Valley has the largest concentration of livestock operations in Virginia, with almost 528,000 cows, 160 million chickens, and 16 million turkeys raised annually.

A significant issue contributing to water pollution in the Shenandoah Valley is the lack of streamside fencing on farms with cattle. In 2019, it was reported that only one in five of the livestock farms in the Valley's biggest livestock counties, Augusta and Rockingham, had fenced their cattle out of streams. This allowed cows to defecate directly into the waterways, leading to high levels of E. coli bacteria and other pollutants.

The Environmental Integrity Project and Shenandoah Riverkeeper's analysis of aerial photographs in 2019 revealed that 81% of farms in these two counties failed to implement proper fencing. This issue was also prevalent in Rockingham County, the Valley's largest agricultural county, where 80% of the 841 farms with livestock did not have adequate fencing to keep animals away from streams.

The absence of streamside fencing has severe consequences for water quality. Cattle wading and defecating in the rivers contribute to pollution, making the waters unsafe for recreation and even dangerous for those seeking drinking water. The manure from the livestock contains high levels of phosphorus, which acts as a fertilizer for the excessive growth of algae. This algae bloom reduces oxygen levels in the water, creating an environment where fish cannot breathe and other marine organisms struggle to survive.

Recognizing the urgency of the situation, Virginia passed legislation in 2020 to provide increased funding for farmers to install exclusionary fencing to keep cattle out of streams. The state set a deadline of 2025 for completing this process, aligning with its pledge to the EPA to have livestock fencing along 95% of streams through pastures. This initiative not only protects the public and the environment but also safeguards the health of the cattle themselves.

Phosphorus pollution fuels algae growth

The Shenandoah Valley, known for its cultural heritage and natural beauty, is home to a thriving livestock and poultry industry. The Valley has nearly 528,000 cows, 160 million chickens, and 16 million turkeys raised annually. This intensive animal farming results in a massive amount of manure, which is often spread on surrounding farmland as fertiliser. However, this manure contains excessive levels of phosphorus, a plant nutrient, which is not fully utilised by crops and leads to phosphorus pollution in the Valley's waterways.

The algae blooms deplete oxygen levels in the water, creating dead zones where fish and other aquatic organisms cannot survive. Different types of algae attach themselves to the riverbed, coating the floor and killing marine life. This not only disrupts the fishing industry but also discourages tourism as people are less inclined to visit the river due to the unpleasant sight and smell of rotting algae.

To address this issue, Virginia passed legislation in 2020 to provide increased funding for farmers to install fencing to keep cattle out of streams. This initiative aims to reduce the direct contamination of waterways by cattle waste. Additionally, the state has recommended implementing better systems for collecting and disposing of surplus livestock manure and requiring all farms that spread manure to have fertiliser management plans. These measures are crucial to mitigating phosphorus pollution and its contribution to algae growth in the Shenandoah Valley's waterways.

While progress has been made, challenges remain. In 2023, 21 out of 52 water monitoring locations in the Valley had levels of E. coli bacteria that exceeded safe limits for swimming or water contact recreation. This indicates that manure runoff continues to be an issue, contributing to both bacterial contamination and phosphorus pollution, which fuels algae growth. To protect the Valley's natural beauty and support recreational activities, further efforts are needed to effectively manage livestock waste and reduce phosphorus pollution in the Shenandoah River and its tributaries.

Pollution impacting Shenandoah Valley's natural beauty and recreational activities

The Shenandoah Valley, known for its cultural heritage and natural beauty, is also home to a large livestock and poultry industry. The valley's waters have been impacted by pollution from manure and bacteria, which has had negative effects on the region's recreational activities.

The livestock industry in the Shenandoah Valley includes almost 528,000 cows, 160 million chickens, and 16 million turkeys raised annually in Augusta, Page, Shenandoah, and Rockingham counties. The manure from these animals is often spread on surrounding farmland as fertilizer, but it contains high levels of phosphorus, nitrogen, and bacteria that can pollute groundwater and nearby streams. This has led to excessive algae growth, which can be harmful to marine life and discourage river-based recreational activities.

A significant issue contributing to the pollution is the lack of streamside fencing on farms with cattle. In 2019, it was reported that 81% of farms in Augusta and Rockingham counties, the state's two largest farming counties, failed to fence their cattle out of streams. This allowed the animals to defecate in the waterways, adding to the bacterial contamination. In 2020, Virginia passed legislation providing funding for farmers to install fencing to keep cattle out of streams, with a deadline of 2025. While some farmers have taken advantage of this funding, there have been calls to delay the deadline, which could set back the progress made in improving water quality.

The pollution in the Shenandoah Valley's waterways has impacted recreational activities such as swimming, tubing, kayaking, and fishing. In 2021 and 2022, more than half of the water quality monitoring sites in the valley detected levels of E. coli bacteria that were considered unsafe for swimming by the EPA. The state of Virginia has been criticized for failing to warn swimmers, tubers, and kayakers about the health risks associated with bacterial contamination in the water.

To address the pollution problem, various measures have been proposed and implemented. In 2022, the Virginia General Assembly approved $265 million for farm pollution-control "best management practices," including streamside livestock fencing. Additionally, organizations like the Environmental Integrity Project and the Shenandoah Riverkeeper have recommended that Virginia establish a better system for collecting and disposing of surplus livestock manure and require fertilizer management plans for farms that spread manure. These efforts aim to reduce the impact of pollution on the Shenandoah Valley's natural beauty and recreational activities.
