Details: SUMMARY: Review Tracer Study & Troubleshoot a Solution to Increase CT DETAILS: Scott, his vendor - Steve Gesdahl - and I are working on two things:
1. Installing verifiable treatment & 2. Identifying accurate CTs for the system.

The existing nanofilter integrity cannot be tested weekly, as required. So they are installing crypto-rated cartridge filters.

The CT required in the summer ranges from 23 to 50. There is really only 25 minutes of contact time in the worst case scenario.
Therefore Scott needs to increase chlorine and contact time for the summer. There are several options we still need to review. ACTION NEEDED: Identify approach to achieving CTs this summer.

Assure new Harmsco HIF-14 PPD-1 filters are installed before camp begins in June.
