NEENAH, Wis. (AP) -- Gov. Scott Walker is praising the pace of cleanup at the Lower Fox River, saying continued progress could lead to officials lifting restrictions on eating walleye from the river.
Walker cited recent monitoring on Thursday that says the water is cleaner than expected. He says the results mark a great milestone in the river's recovery.
The river was heavily contaminated by toxic chemicals called PCBs, a by-product of paper manufacturing. The chemicals cause cancer in wildlife and are a likely carcinogen for humans.
Several paper companies are paying for the cleanup, overseen by state and federal officials.
Walker says PCB levels are down 73 percent in walleye in Lake Butte des Morts (BYOO'-deh-mohr). He says if the same level is confirmed next year, an advisory restricting fish consumption will be lifted.
