From the Research
Drinking water near a golf course is not recommended due to the potential risk of contamination from pesticides, herbicides, and fertilizers, which can increase the risk of developing conditions such as Parkinson's disease, as suggested by a recent study 1. The use of industrial byproducts to filter phosphorus and pesticides in golf green drainage water has shown some promise, but the effectiveness of such methods can vary depending on factors such as flow rate and contaminant properties 2. Some key points to consider when evaluating the safety of drinking water near a golf course include:
- The potential for contamination from pesticides, herbicides, and fertilizers, which can leach into nearby water sources, especially after rainfall
- The importance of regular testing and treatment of water supplies to meet safety standards
- The potential benefits of using home water filtration systems that use activated carbon or reverse osmosis to remove chemical contaminants
- The need for individuals with private wells near golf courses to have their water tested regularly for pesticides, nitrates, and other potential contaminants A study published in 2025 found that living within 1 mile of a golf course was associated with a 126% increased odds of developing Parkinson's disease compared to individuals living more than 6 miles away from a golf course 1. Overall, while the evidence suggests that drinking water near a golf course may pose some risks, the level of risk can vary depending on a range of factors, and individuals should take steps to minimize their exposure to potential contaminants.
