Other Violations/Staff Remarks:
ORC indicated "this was a short week and we were not notified until we received report with results on it. I have contacted our lab
to make sure they notify us when we are over limits. We also cleaned our contact chamber and had a company come out to try to
help with this issue. We have also started a new/different type of settling agent to help with our solids."
