Concluding a two-year investigation by six federal and state agencies, a U.S. District Court in Indiana on Nov. 9 cleared United Water of all charges against two United Water employees for sampling violations at a city-owned wastewater treatment plant in Gary, Ind.

If convicted, the company’s former plant manager and superintendent faced up to five years in prison on a conspiracy count and two years for each felony violation of the Clean Water Act, as well as a criminal fine of up to $250,000 for each count.
