Details: SUMMARY: Sanitary Survey requirement: Tracer Study DETAILS: A Contact Tracer Study was performed on the systems treatment plant. The flow rate from the plant was 32 gpm. All contact time was derived from prechlorination with a dilute solution of 12% hyprochlorite through the body of the plant, with some incidental time contribution, from a short segment of the distribution service line. The C10 was achieved 86 minutes into the study. The Tiller plant should have adequate contact time under almost all circumstances. ACTION NEEDED: A full report will be completed when data is processed.
