ST. LOUIS (AP) -- Missouri officials say raw sewage has been flowing at least since Tuesday into the Mississippi River near St. Louis.
The Department of Natural Resources said Thursday the problem began when floodwaters overwhelmed a Metropolitan Sewer District pumping station in south St. Louis County.
The agency says floodwaters and sewage overflowed from a manhole into Martigney Creek, which flows into the Mississippi. The pressure also caused a line to burst, also sending untreated wastewater into the creek.
DNR says the sewer district reported the overflow Tuesday afternoon. Officials estimate the wastewater flow at 1,500 gallons per minute.
An undetermined number of fish have been killed in the creek.
The sewage was expected to keep flowing until floodwaters recede enough to allow the line to be repaired.
