Overview

• A study published in JAMA Network Open found that living within one mile of golf courses doubles the odds of developing Parkinson's disease compared to living more than six miles away.
• Researchers identified pesticide runoff contaminating shared municipal and groundwater supplies as a likely pathway for the increased risk.
• The study analyzed 450 Parkinson's cases in Olmsted County, Minnesota, using data from the USGS and municipal water records across Wisconsin and Minnesota.
• Experts emphasize that while the findings are significant, additional research is needed to confirm causation and address gaps, such as untested water samples and participants' residential histories.
• Advocacy groups and researchers are calling for stricter pesticide regulations and increased investment in prevention to mitigate environmental health risks.
