Reasons: Coliform
N/A
 
Details: SUMMARY: Routine +TC DETAILS: Jennifer reported that a routine sample collected Monday 9/25/17 at 16408 SW Titan Lane came back positive for total coliform/absent for E. coli. Three repeats were collected 9/26/17 (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 Thursday 9/28/17 she reported that all 3 repeats were absent for both total coliform and E. coli. Jennifer indicated that the cause of the original positive might have been due to contamination of the sampling station but she was not sure. 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.
