DISCHARGE LIMITS
Treated wastewater is discharged into the East Fork of the White River immediately south of the downtown area. The water is monitored several times each day to ensure that it meets stringent water quality standards.
Water quality standards are established under the Federal Clean water act and are specifically set forth for Columbus in its NPDES permit.
Specific, prohibitive, limits are established for all categorical pollutants including metals.
In addition, limits are set for BOD, ammonia and other compatible pollutants.
