GREEN BAY, Wis. (WBAY) - The Fox River cleanup project is continuing its ninth season of dredging chemicals from the lower Fox River.
The project is reducing the risk to human health and the environment by removing cancer-causing PCBs from the riverbed.
There are four dredge barges on the river. One is part of a diving operation.
Project crews are using flags, buoys and other safety markers to show where boating is allowed -- and where it isn't -- during the cleanup, which is expected to continue into mid-November.
Local authorities, including the Coast Guard and Green Bay Police marine unit, held a news conference Tuesday reminding boaters about the dredging and the safety markers ahead of the Memorial Day weekend and summer vacation season.
They say safety for both the cleanup crews and boaters is the top priority.
"We encourage boaters to be knowledgeable of where the dredges are, where the buoys are, so that they can protect themselves and keep other people safe," Police Capt. Kevin Warych said.
Information about the cleanup project, including weekly updates on current operations and photos of the diver flags can be found on the Fox River Cleanup Project website
