The Department of Natural Resources may push for tighter compliance in Vandalia’s wastewater treatment operations.
Pending ammonia testing at the city’s effluent lagoons, Vandalia could spend more money on measures in order to control the contaminant as a result.
The city asked for a 12-month monitoring period in its current compliance report to the department. The testing would allow the city to see whether recent upgrades of its wastewater operations will continue keeping ammonia levels at bay.
As of late, the city has stayed within allowed levels with minor slips. However, dry weather conditions may have affected the numbers. The test will be whether the system can maintain compliance in normal weather conditions. The Department of Natural Resources called for an ammonia reduction plan as part of the National Pollutant Discharge Elimination Program wastewater permit program.
“There are several things we have done to reduce ammonia in our lagoons,” Vandalia City Administrator Alan Winders told the city’ board of aldermen on Tuesday, March 12. “Our ammonia numbers have continued to get better and better since then.”
