|Assistance Type:||CIRCUIT RIDER ASSISTANCE|
The water system has added a solar-bee mixer and wishes to have a CT study done to determine the effect the new mixer is having on the contact time.
The methodology has been created and approved by OHA. A tracer test was attempted on 02/25/21. During the test, the operator turned off the chlorinator due to fears that the residual to distribution would be too high. There is a process chlorine meter that has historically shown wildly high readings, normally 20 ppm, these readings had climbed to 60 ppm during the test.
Lack of continued communication has resulted in this support being closed
Follow-Up Actions Needed:
Once the problem chlorine meter addressed then they can re-run the tracer test.
