Overspill

They do not play,
but live beside
the tailored grass.

Fairways curve
where warnings should.

The air carries
what water cannot hold.

A hand begins to shake.
A name
slips from the scorecard.

No fence keeps out
what was never invited.

This poem was inspired by recent research, which found that living within proximity to a golf course increases the risk of Parkinson’s disease.

Many people enjoy living near green, open spaces – golf courses among them – but there is growing concern that such environments may bring hidden risks. In particular, pesticides commonly used to maintain golf courses have raised alarm due to their potential link to Parkinson’s disease, a progressive neurological condition. While previous studies have explored pesticide exposure in agricultural settings, far less is known about how exposure from golf courses might affect those living nearby. Drinking water may be one possible route of exposure, especially in areas where groundwater is more vulnerable to contamination.

This study examined health records from over two decades in one US region, comparing people diagnosed with Parkinson’s disease to similar individuals without the condition. It found that those living within 1 to 3 miles of a golf course were more likely to develop Parkinson’s disease, with the greatest risk for those living within 1 mile. The link was even stronger for people in areas where drinking water came from vulnerable groundwater sources serving golf courses. These findings suggest that pesticide use on golf courses may contribute to the risk of Parkinson’s disease, especially where contamination of drinking water is more likely. This research offers important evidence to inform future public health decisions about land use, pesticide regulation, and water safety.
