Golf Course Runoff: A Hidden Source Of Water Pollution

Golf courses are often constructed near natural water bodies, and the process of construction involves removing the original natural soil cover, which can cause soil erosion and nutrient transport. Runoff from golf courses can carry pollutants such as pesticides, fertilizers, and petroleum into nearby ponds, streams, and lakes, affecting the quality of freshwater sources. The maintenance of neat greens and grounds on golf courses requires a significant amount of water, fertilizer, and weed control measures, which can lead to an over-concentration of chemicals and nutrients in the water. This, in turn, can harm wildlife habitats and disrupt the natural balance of ecosystems. Golf course managers are responsible for minimizing the impact of their operations on the environment and are recommended to implement practices that reduce the risk of pollutants entering water sources.

Pesticides and fertilizers

Golf courses use pesticides and fertilizers to maintain their grounds. However, these chemicals can be harmful to the environment and human health if not properly managed.

Pesticides are used to kill weeds and insects, and fertilizers are used to promote grass growth. While workers generally understand the basic function of these chemicals, there is a lack of knowledge about the specific dangers they pose. For example, a study found that golf course superintendents and grounds maintenance workers had little knowledge about pesticides and inadequate safety training. This is concerning because exposure to pesticides has been linked to elevated risks of various cancers and nervous system disorders.

The use of pesticides and fertilizers on golf courses can lead to water pollution through runoff. When it rains, these chemicals can be washed into nearby ponds, streams, or lakes, contaminating water sources. This is a particular concern for golf courses located near residential areas, as the pollutants can impact the health of the surrounding community.

To minimize the risk of pollution, golf course managers can implement certain practices. For example, a study by the USDA found that hollow tine core cultivation (HTCC) was more effective than verticutting in absorbing runoff and reducing pesticide runoff. Additionally, placing a buffer between turfgrass and a body of water can help reduce nutrient and sediment runoff.

By following best management practices and guidelines for pesticide and fertilizer use, golf course managers can minimize the risk of pollution and protect the environment and human health.

Water pollution

Golf courses require a lot of maintenance, which often involves the use of pesticides, herbicides, and fertilizers. The use of these chemicals, coupled with the large amounts of water needed to maintain a golf course, can lead to water pollution.

Golf courses are often constructed near natural water bodies, and establishing a new course involves removing the original natural soil cover. This can lead to the contamination of nearby water sources through soil erosion and the transport of nutrients and pollutants such as pesticides, herbicides, and fertilizers. Overwatering can also cause excessive soil leaching and increase surface water runoff, carrying these contaminants off the golf course and into nearby ponds, streams, or lakes.

The water that flows through a golf course can pick up contaminants as it moves, including pesticides, fertilizers, and even petroleum. Over-irrigation and stormwater runoff can exacerbate this type of contamination, leading to water pollution. The use of aboveground storage tanks for chemicals, pesticides, and fuels on golf courses can also present a risk of water pollution in the event of a spill or leak.

ARS scientists in St. Paul, Minnesota, are working to protect waterways by minimizing runoff from golf courses. Their research has shown that certain turf management practices, such as hollow tine core cultivation (HTCC), can help to absorb more runoff and reduce the flow of pesticides and fertilizers into nearby water sources. Implementing buffer strips and vegetation along water bodies can also help to catch and trap sediment, nutrients, pesticides, and other pollutants before they reach surface waters.

By following recommended practices and properly managing the use and storage of chemicals, golf course managers can minimize the risk of water pollution and maintain environmentally friendly spaces.

Soil erosion

One of the main causes of soil erosion on golf courses is water runoff and flooding. During heavy rainfall or due to inadequate drainage systems, excessive water runoff can occur, especially on sloping greens. The force of the water can dislodge soil particles, creating erosion channels and gullies. Poor drainage systems can also contribute to water pooling and flooding, exacerbating the problem.

Foot traffic from golfers and the movement of golf carts can also accelerate soil erosion, particularly on vulnerable areas such as slopes and high-traffic zones. Compacted soil becomes more susceptible to erosion, and the constant wear and tear can make the problem worse. Severe weather events, such as storms and high winds, can further contribute to erosion by exposing areas of the greens and causing structural damage.

To combat soil erosion and maintain optimal playing conditions, golf course managers can implement various solutions. Proper grading and slope stabilization techniques can help redirect water flow and prevent erosion. Strategic reshaping of slopes and the addition of erosion control measures such as retaining walls or terracing can ensure consistent playability and minimize erosion risks.

Vegetation and turf management are also crucial. Using erosion-resistant grass species and implementing proper turf management practices can enhance the resilience of greens against erosion. Techniques such as overseeding, regular fertilization, and adequate irrigation promote healthy turf growth, making it more resistant to erosion.

Additionally, improving drainage systems is essential to managing excess water and preventing erosion. Modern irrigation systems can help reduce runoff by making better use of water. Soil cultivation techniques such as hollow tine core cultivation (HTCC) and "verticutting" can also help to aerate the soil, making it less compacted and better able to absorb water, thereby reducing runoff.

Storage tank leaks

Golf courses can be a source of pollution, with the potential to impact the surrounding environment and local communities. With over 15,000 golf courses in the United States alone, covering approximately 1.7 million acres of land, the potential for pollution is significant. One source of pollution on golf courses is storage tank leaks, which can have detrimental effects on the environment and human health.

Storage tanks are commonly used on golf courses to store various chemicals, pesticides, fuels, and fertilisers. These tanks can be above ground or underground, and both types pose unique risks and challenges. Above-ground storage tanks are more susceptible to spills and leaks, which can contaminate the surrounding environment and result in costly cleanup bills. Underground storage tanks (USTs), on the other hand, are more prone to corrosion and leakage, which can go undetected due to their buried nature.

Underground storage tanks (USTs) are often used for storing large quantities of liquids or gases, including petroleum products. Leaks from USTs can have severe consequences, including fire, explosion, and fume hazards. The main causes of UST leaks include piping failure, spills, overfills, and tank corrosion. Improper installation and maintenance are often to blame for these issues, and even small leaks can pose a significant risk to the environment and workplace safety. Concrete used to secure USTs can also act as a barrier, making leaks more difficult to detect, which can result in prolonged environmental contamination.

To prevent UST leaks, it is crucial to ensure proper installation and maintenance. Regular inspections, leak detection, and performance monitoring are essential components of a comprehensive maintenance program. Additionally, understanding the common causes of leaks can help develop effective prevention and detection strategies. In the event of a leak, prompt detection and remediation are critical to minimising environmental impact and potential penalties for non-compliance.

Storage tank coverage and site pollution liability insurance can help protect against the financial costs associated with leaks and spills. The PartnerOne Fuel Solutions program, for example, offers coverage for cleanup costs and potential fines. Implementing proper planning, equipment calibration, and secure storage facilities for pesticides can also help reduce the risk of runoff and groundwater contamination. By taking proactive measures and adhering to safety regulations, golf course managers can minimise the risk of pollution and protect the environment and surrounding communities.

Stormwater runoff

The construction of a golf course often involves removing the original natural soil cover, disturbing the natural landscape, and increasing the risk of soil erosion. This soil erosion, combined with the use of fertilisers and chemicals, results in nutrient-rich runoff that can contaminate nearby water bodies. This runoff can carry pollutants such as soil nutrients, suspended particles, pesticides, herbicides, and excess fertiliser into freshwater ponds, streams, and lakes, located close to the golf course.

The impact of stormwater runoff from golf courses can be mitigated through various measures. One approach is to implement proper irrigation practices, avoiding overwatering to reduce surface water runoff. Modern irrigation systems can help optimise water usage and minimise runoff. Additionally, buffer strips and vegetation along water bodies can act as filters, trapping sediment, nutrients, and pollutants before they reach these water sources. Maintaining healthy turf is another effective strategy, as it requires fewer fertilisers and plant protectants, while also improving water filtration and reducing soil erosion.

Golf course managers play a crucial role in minimising the environmental impact of their facilities. This includes the proper storage, handling, and disposal of chemicals to prevent spills and contamination of water sources. Adopting recommended management practices, such as using slow-release fertilisers and establishing thick vegetative buffers around water bodies, can also help reduce nutrient runoff into nearby ponds and streams. By following these measures, golf course managers can help protect the environment and maintain the ecological balance of the surrounding areas.
