Pocatello residents were alerted April 11 that elevated levels of bacteria had been discharged from the city's wastewater treatment plant into the Portneuf River.

While city officials insisted there was no emergency and drinking water systems in the eastern Idaho community would not be impacted, KIDK-TV reported confirmation that higher-than-normal levels of E. coli bacteria had been discovered March 31 in wastewater leaving the plant.

According to officials, the amount of chlorine used to treat the wastewater was not sufficient that day. As a result, E.coli levels in the water being sent into the Portneuf River exceeded the daily maximum limit. City officials said the issue was corrected the following day.

“We have already taken steps to prevent this from happening again and later this spring, the city’s new ultraviolet disinfection system will be operational, further improving the efficiency of the disinfection process," wrote Pocatello Public Works Director Michael Jaglowski in a prepared statement.
