The Shelby County Sheriff’s Office is investigating several instances of trash dumping by the Great Miami River in Sidney.

The investigation was spurred by a “Clean Sweep” event in which a larger-than-average amount of trash was discovered. The clean-up was performed by several groups of people.

One group, called “Protecting Our Water Ways,” cleaned from the south edge of Sidney to the south edge of Piqua. The group found and cleaned up 7,000 pounds of roofing shingles and nails, a 200-gallon water tank full of silt, 53 tires and a 55-gallon drum of used motor oil.

A group cleaning from Quincy to the south edge of Sidney discovered and removed 3,000 pounds of items from the area of Custenborder Field to Roadside Park.

The Sheriff’s Office is seeking the public’s assistance in finding people responsible for trash dumping. Anyone with information is asked to call (937) 498-1111 or call Crime Stoppers anonymously at (937) 492-8477.
