ST. LOUIS (AP) -- Environmental authorities are trying to assess to what extent a towboat that sank in the Mississippi River at its mooring near St. Louis' downtown may be leaking diesel fuel.
The Missouri Department of Natural Resources says the towboat that sank Wednesday evening near the McKinley Bridge was carrying nearly 8,600 gallons of red dye diesel fuel.
Renee Bungart, a DNR spokeswoman, says the boat may have leaked some of that fuel.
Bungart says it's not believed anyone was injured, and it's not clear what caused the boat to go down.
The vessel belongs to American River Transportation Co., owned by agribusiness giant Archer Daniels Midland based in Decatur, Ill.
After noticing a sheen on the water after the sinking, the DNR placed absorbent booms in the river to contain the fuel.
Public drinking water sources downstream were notified.
