| Assistance Type: | OTHER REGULATORY - Clarification on monthly surface water reports | ||
| Reasons: | SWTR Operations |
||
| Details: | Pete clarified surface report readings on several days in January, February, and March where there were no turbidity readings, but disinfection CT and chlorine residual readings. The filter produces water and fills up the large disinfection contact time clearwell, and the system runs off of the clearwell volume for up to a day, with the filter plant off. Therefore on some individual days you have no turbidity readings, but disinfection data. | ||
