The natural filtration capabilities of turfgrass have been well documented. There are several published studies as well as many cases of anecdotal evidence that indicate that water leaving a golf course is cleaner than when it enters the property.
For a long time, golf courses have been labeled as polluters of the environment, not stewards, so can superintendents actually make this claim when presenting to their boards or speaking in response to environmental groups? They can if they have the data, says J. Bryan Unruh, Ph.D., of the University of Florida.
In this TurfNet University Webinar entitled "Water quality monitoring on the golf course", Dr. Unruh offers evidence-based proof of the cleansing properties of turfgrass and how superintendents can arm themselves with this knowledge and use it to their advantage.
