Details:	SUMMARY: Routine +TC DETAILS: Joel reported that a routine sample collected yesterday (Wednesday 9/7/16) from sample station #48 came back positive for total coliform (absent E. coli). Three repeats will be collected today (upstream, downstream, and the original site). The Grabhorn well was not running at the time so no triggered source water sample needed. There was no suspected possible cause for the positive. ACTION NEEDED: Will wait for results of repeat samples (available Friday 9/9/16) and respond accordingly. Update: TVWD notified the department friday that all repeat sampling was absent of coliform.
