Watershed Pollution: Understanding The Devastating Consequences

Watersheds are areas of land that drain rainwater or snow into one location, such as a stream, lake or wetland. They are essential for human life, providing drinking water, water for agriculture and manufacturing, and supporting recreation and wildlife. However, when a watershed is polluted, the water we rely on for these purposes is put at risk. Contaminants can infiltrate groundwater and concentrate in streams and rivers, ultimately being carried down the watershed and into the ocean. This can have devastating effects on aquatic ecosystems, including the formation of large dead zones in the ocean and threats to coral reef ecosystems. Additionally, pollution in watersheds can impact human health, contaminate the food we eat, and affect the health of the soil, vegetation, and animals that depend on clean water and air.

Drinking water is put at risk

When a watershed is polluted, the water we rely on for drinking is put at risk. A watershed is an area of land that drains rainwater or snow into one location, such as a stream, lake or wetland. These water bodies supply our drinking water, water for agriculture and manufacturing, and offer opportunities for recreation.

Watersheds can be polluted by industrial activities, such as the release of chemicals into waterways. For example, a recent study found that the Chemours facility in Fayetteville released a chemical called GenX into the lower Cape Fear River. GenX is a man-made chemical compound known as a per-and polyfluoroalkyl substance (PFAS), which is used in commercial products such as food packaging, non-stick coatings and firefighting foam. The release of these chemicals can negatively impact drinking water quality and human health.

Another source of pollution is urban development and agricultural operations. When vegetation is replaced by impervious surfaces like roads and parking lots, it can increase the frequency and volume of stormwater runoff, carrying more pollutants such as sediments, bacteria and nutrients into waterways. Agricultural operations that discharge animal waste into open lagoons and apply fertiliser on fields can also contribute to pollution. Flooding can cause these lagoons to overflow and the fields to become oversaturated, sending large amounts of nutrients into waterways.

These pollutants can infiltrate groundwater and concentrate in streams and rivers, ultimately being carried down the watershed and into the ocean. Nonpoint source pollution is linked to the formation of large dead zones (areas with minimal oxygen) in the ocean and also threatens coral reef ecosystems around the world.

The vegetation within watersheds can play an important role in reducing the impact of pollution. Vegetation can slow the flow of stormwater runoff and remove pollution as it flows across the ground, reducing the costs for drinking water treatment and minimising property damage caused by flooding. Protecting the quality of watersheds is crucial, as they sustain life and support economic activities such as agriculture, manufacturing and tourism.

Animal species can become contaminated and sick

When a watershed is polluted, animal species can become contaminated and sick. This can happen when they ingest polluted water, or when they eat other animals that have been contaminated. For example, fish that we eat can become contaminated and sick from polluted water. This can then be passed on to humans.

Watersheds are areas of land that drain rainwater or snow into one location, such as a stream, lake, or wetland. These water bodies supply our drinking water, water for agriculture and manufacturing, and provide habitats for numerous plants and animals. When a watershed is polluted, it can put all of these things at risk.

There are several ways that watersheds can become polluted. Urban development and agricultural operations can pose serious threats to watershed health. When vegetation is replaced by impervious surfaces like roads and parking lots, it can increase the frequency and volume of stormwater runoff. This runoff can carry pollutants such as sediments, bacteria, and nutrients into waterways. Agricultural operations that discharge animal waste into open lagoons and apply fertiliser to fields can also cause pollution. If these fields become oversaturated, large amounts of nutrients can be sent into waterways.

Industrial activities can also negatively impact watersheds. For example, a recent study found that a facility in Fayetteville released a chemical called GenX into the lower Cape Fear River. GenX is a man-made chemical compound known as a per-and polyfluoroalkyl substance (PFAS), which is used in commercial products such as food packaging and non-stick coatings. The release of these chemicals can negatively impact drinking water quality and human health.

Air pollution can affect the health of the soil, vegetation, and animals

Additionally, air pollution can result in the deposition of toxic substances on the ground, which can be absorbed by plants and animals, leading to health issues and even death. The impact of air pollution on vegetation and animals can have far-reaching consequences, as it can disrupt food chains and ecosystems, affecting the health of entire communities.

Soil, which is essential for plant growth and nutrient cycling, can also be affected by air pollution. Air pollutants can contaminate the soil, reducing its fertility and ability to support plant life. This, in turn, can impact the health of animals that depend on plants for food and habitat.

Furthermore, air pollution can contribute to climate change, leading to changes in temperature and precipitation patterns. These changes can impact the distribution and health of vegetation and animal species, as they may struggle to adapt to new environmental conditions.

The effects of air pollution on the health of the soil, vegetation, and animals are complex and interconnected. While air pollution can directly impact these components of the watershed, it can also have indirect effects, such as altering the composition of the atmosphere and changing weather patterns. Therefore, it is crucial to address air pollution and implement measures to protect and restore the health of watershed ecosystems.

Polluted water can reach the sea and impact coastal communities and sea life

Urban development and agricultural operations pose serious threats to watershed health. When vegetation is replaced by impervious surfaces like roads and parking lots, it can increase the frequency and volume of stormwater runoff so that it carries more pollutants such as sediments, bacteria and nutrients into waterways. Agricultural operations that discharge animal waste into open lagoons and apply fertiliser on fields can also cause flooding, which can make the lagoons overflow and the fields become oversaturated, sending large amounts of nutrients into waterways.

Industrial activities can also negatively impact watersheds. For example, a study found that the Chemours facility in Fayetteville released a chemical called GenX into the lower Cape Fear River. GenX is a man-made chemical compound known as per-and polyfluoroalkyl substances (PFAS), which are used in commercial products such as food packaging, nonstick coatings and firefighting foam. The release of these chemicals can negatively impact drinking water quality and human health.

As water runs over and through the watershed, it picks up and carries contaminants and soil. If untreated, these pollutants wash directly into waterways carried by runoff from rain and snowmelt. These contaminants can infiltrate groundwater and concentrate in streams and rivers, ultimately being carried down the watershed and into the ocean. Nonpoint source pollution is linked to the formation of large dead zones (areas with minimal oxygen) in the ocean and also threatens coral reef ecosystems around the world.
