Contacted By: WRAY, JULIE (DWP)
Contact Method/Location: Field
Details: Background/Problem Identification:

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. OHA has suggested that two tests are done, one with the mixer on, and one with the mixer off.

Assistance Provided:

The methodology has been created and approved by OHA. The operator (Don) wants push back the tracer testing due to operational issues relating to the amount of water available in the summer from their spring. Don will reach back out to Civil West to finish the tracer test once the spring is flowing stronger.

Follow-Up Actions Needed:

The tracer study will be performed once the town is ready, likely in a month or two when their spring is recharged.

Technical Reports to be Prepared and Expected Timeframe:
