Details:	SUMMARY: Positive temporary routines DETAILS: Dougs response to my email…"WE did shock the well but it did not seem to remove all the bacteria. On Monday the 17th we installed a temporary chlorination system at the inlet to the storage tank. Chlorine was injected each time the well pump came on and chlorine residuals were measured several times each day. Residuals ranged from 0.07 mg/L to 1015 with an average of 0.28 mg/L. The chlorination system was shut off this morning and put back into its regular operating mode. We will collect the 5 temporary routines next Friday to see if the chlorination of the entire system was successful. A source water sample will be collected at that time. ACTION NEEDED: Wait to see results of 11/4/11 samples
