LANSING — When Melody Lowery visits her aunt’s house at Bay Harbor, she collects golf balls that wash up along the Lake Michigan beach.
More than a handful end up along the shore of Little Traverse Bay.
“One time, we filled up more than a suitcase collecting golf balls,” the Midland resident said.
While microplastics get plenty of attention as a Great Lakes pollutant, researchers say there isn’t enough information to know if macroplastic golf balls pose similar harm in freshwater systems.
NPR recently reported that divers in Carmel, California, found more than 50,000 golf balls over two years. Golf balls release zinc compounds that are toxic and degrade into microplastic pieces.
Sediment studies that occur far off the coast are unlikely to measure golf ball pollution in the Great Lakes, said Sherri Mason, a Great Lakes microplastics expert and the sustainability coordinator at Penn State Behrend University in Erie, Pennsylvania. That makes it hard to get significant data.
“I don’t think anyone can say one way or the other what the extent of golf ball pollution of the Great Lakes is,” Mason said. “I would assume that relative to the amount of plastic products we use and lose, golf balls are likely not currently a major contributor.”
Michigan leads the nation in the number of top courses with national acclaim. But there is no fine for hitting golf balls into lakes, said Adam Ikamas, the executive director of the Michigan Golf Course Superintendents Association.
That may be due to uncertainty and lack of opportunity. The effects of this plastic pollutant are unknown. And there are maybe two dozen courses in the state where golfers could hit balls into the Great Lakes, Ikamas said.
Some scientists say that the decomposition of millions of golf balls may pose a problem.
Dangerous levels of zinc were found in the synthetic rubber filling used in solid core golf balls, researchers for the Danish Golf Association told CNN. Zinc can poison vegetation. And golf ball chemicals can break down into microplastics which animals eat, according to a study in the Marine Pollution Bulletin.
Mason said scientists don’t yet know if decomposition in freshwater systems is the same as in the ocean. The Great Lakes have a lot more life that could be aiding in the breakdown of golf balls.
While an estimated 300 million golf balls lost at the bottom of U.S. water hazards may make some people uneasy, a Michigan man is set on retrieving them.
Jim Starr, president of Absolute Golf Ball Retrieval in Utica, has a network of independent divers who retrieve balls from water hazards. After retiring as a Middle East contractor, Starr built the golf ball recycling business that works with more than 400 Michigan golf courses and employs disabled workers.
The corporation is unique because it employs a segment of the population that normally is disadvantaged at finding work, Starr said.
He employs close to 100 people through Growth and Opportunity, a nonprofit corporation in Lapeer County.
They refurbish, package and recycle millions of golf balls collected by Starr and other divers.
“I retrieve millions of golf balls and I barely touch the whole entire state,” said Starr, whose business expanded in 2017 after he joined a cooperative called Golf Ball Divers Alliance.
That partnership helps maintain a fair payment to independent divers, he said. By allowing for the direct sale of golf balls to customers, the cooperative also maintains an affordable price.
There isn’t a noticeable change in the playability of balls that have been submerged for up to three months, according to a study by Oakland University.
“I do a lot of recreational scuba diving, and I have never been in a body of water that I have not found golf balls, Starr said. “I dive right at the mouth of Port Huron, and you find golf balls there that have gotten into the Great Lakes and rolled down there.”
Not as many balls are retrieved from rivers and streams as from standing lakes and ponds.
Starr uses mostly environmentally friendly and non-corrosive chemicals to clean each ball, he said. “We try to run our business in good ways for the environment and for the people.”
