WASTEWATER TREATMENT PLANT – UNTREATED WASTEWATER A process tank at a wastewater treatment plant malfunctioned, discharging a large volume of untreated wastewater into a nearby stream. This discharge caused a fish kill as well as damage to many aquatic plants. The local regulatory authority issued fines to the operator of the wastewater treatment plant for the unauthorized discharge. In addition several local residents as well as an environmental group filed suits for loss of enjoyment of the creek.
