They proposed a change to the action plan to resolve the TC+s: Feed both upper and lower distributions with chlorinated wells 2 & 3 by opening a few valves that connect the two distribution systems that can be opened in emergencies. And temporarily stop using the lower system well, #1. And temporarily stop using Reservoir #3 which got a TC+ Friday. ACTION NEEDED: 1. Limited flushing of the lower system with chlorinated wells.
2. Simultaneously, gently chlorinate lower distribution system.
3. Clean Reservoir #3 (and #1 and #2) 8 November 2012.
