Milwaukee Volunteers Aim to Break River Cleanup World Record

For over three decades, thousands of Milwaukee residents have shown up every spring to do something remarkable: clean more than 100,000 pounds of trash from their local rivers in just a few hours.

This year, they're making it official. On April 25, Milwaukee Riverkeeper's Spring Cleanup will attempt to break the Guinness World Record for the most volunteers participating in a one-day, multiple-site river cleanup.

The current record belongs to volunteers in the UK who cleaned the River Taff last March. But here's the twist: Milwaukee's annual cleanup has been quietly beating that number for years without anyone tracking it.

"For years, Milwaukee Riverkeeper volunteers have quietly and unknowingly eclipsed the world record," said Brad Liski, CEO of Tru Earth, the eco-friendly cleaning company partnering on the record attempt. The goal is to shine a spotlight on everyday people doing extraordinary work for their community.

From 9 a.m. to noon, volunteers will gather at over 100 locations across Milwaukee, Ozaukee, Waukesha, and Washington Counties. They'll remove litter, plastic, and pollution from rivers and green spaces throughout the region.

Jennifer Bolger Breceda, Executive Director of Milwaukee Riverkeeper, emphasizes that the record attempt celebrates something deeper. "Healthy rivers are built over time, not in a single day," she said. "A cleaner river doesn't happen by chance, it happens because people show up."

To make the record official, volunteers must pre-register and arrive at their designated cleanup site by 9 a.m. sharp. A coordinated countdown will launch the attempt simultaneously across all locations.

The event needs additional volunteers beyond cleanup crews: counters to track participants and environmental experts to document specifics for official verification. Every registered volunteer will receive a free commemorative t-shirt while supplies last.

The Ripple Effect

After the cleanup, Rock the Green is hosting a free zero-waste celebration at the Harley Davidson Museum from noon to 3 p.m. Volunteers can enjoy live music on a pedal-powered stage, free beer, and take home a native shrub to plant.

This record attempt represents more than just recognition. It showcases what happens when a community commits to caring for shared resources year after year. Milwaukee Riverkeeper is part of the global Waterkeeper Alliance network, connecting local action to worldwide efforts for clean, accessible waterways.

Whether Milwaukee breaks the record or not, 30 years of dedication to healthier rivers has already created something worth celebrating.
