(KMZA)--An operator of the Wamego wastewater treatment facility is accused of sending untreated or inadequately treated sewage into the Kansas River.

U.S. Attorney Stephen McAllister, in a news release, said 47-year-old David Schleif, of Belvue, was indicted Wednesday on federal charges of violating the Clean Water Act.

In addition, Schleif faces 19 counts of using falsified data in discharge monitoring reports. McAllister said the falsified reports showed lower levels of biochemical oxygen demand, total suspended solids and E. coli than indicated by actual tests results.

The crime is alleged to have occurred between May 2017 and August 2019.

If convicted, Schleif faces of up three in prison on the discharge count, plus up to two years and a $10,000 fine for each of the other counts.
