WICHITA, Kan.  -  The Kansas Department of Health and Environment on Friday rescinded its health advisory for the Arkansas River. Officials say testing shows that E. coli bacteria concentrations have returned to acceptable levels.
     The health advisory was issued on May 25 after the KDHE recorded elevated levels of bacteria during routine stream sampling. The original advisory covered the portion of the Arkansas River from the Lincoln Street Bridge to the Oklahoma state line.
     City of Wichita and the KDHE discovered the elevated bacteria level was caused by a leak in a valve at the city’s main wastewater treatment plant. The leak was repaired earlier this week. It is not known how much water leaked from the pump station.
