| Details: | SUMMARY: Routine +EC DETAILS: Dean called to report a routine +E.coli. The sample was collected Wednesday 5/15/13 at sample station #69 in an area north of hwy 26 and west of 185th ave. Total chlorine residual at the time was 1.3 ppm. Three repeats were collected today, Thursday 5/16/13 from upstream, downstream, and the original site. Total chlorine residuals at the repeat sites were 1.18 ppm, 1.4 ppm, and 1.43 ppm respectively. The Grabhorn well wasnt running at the time so no triggered source water sample needed. There was no suspected possible cause for the positive-- nearest waterline construction was occurring 2 miles away and samples taken in relation to that project were fine. ACTION NEEDED: Will wait for results of repeat samples Friday morning 5/17/13 and respond accordingly. UPDATE 7:50 am Friday 5/17/13: TVWD reported that all repeat samples were absent for coliform and E.coli. No further action needed at this time. | ||
