On August 8, 2004, a tour bus belonging to the Dave Matthews Band dumped an estimated 800 pounds (360 kg) of human waste from the bus's blackwater tank through the Kinzie Street Bridge in Chicago onto the passenger sightseeing boat Chicago's Little Lady sailing in the Chicago River below. As part of a legal settlement, the band agreed to pay $200,000 to environmental protection and other projects. The band also donated $100,000 to two groups that protect the river and the surrounding area. The band's bus driver, Stefan Wohl, pleaded guilty to dumping the waste in April 2005.
