Details: SUMMARY: CT calc given backwash flows DETAILS: How should CT be calculated before the next tracer study? The last survey noted the tracer study was based on maximum demand (250 gpm), but that backwash creates a flow of 600 gpm. Thus, a new tracer study should be conducted while backwash is occurring. Until that time, Idanha should use the current contact time base on the last tracer study. Idanha has asked HBH for support in conducting a tracer study. ACTION NEEDED: none
