| Details: | SUMMARY: Routine +TC DETAILS: Jennifer reported that a routine sample collected Monday 10/2/17 at 12200 SW Walnut St. came back positive for total coliform/absent for E. coli. Chlorine residual was good at 0.88 ppm and she did not indicate a possible cause for the original positive. Three repeats were collected 10/3/17 (upstream, downstream, and original site). No wells were running at the time so no triggered raw water well samples were required to be collected. On Wednesday 10/4/17 she reported that all 3 repeats were absent for both total coliform and E. coli. ACTION NEEDED: No further action needed at this time. System can resume routine monitoring and no action is required unless more than 5% of samples are positive for total coliform in the month. | ||
