Assistance Type: WATER QUALITY ALERT RESPONSE
Reasons: Coliform
 
Details: We received a report of a routine positive total coliform sample collected Tuesday 8/13/19. I called Rene to inquire about repeat sampling, and he indicated three repeats (original site, upstream, downstream) had been collected today Wed. 8/14/19. Chlorine residual was normal (1 ppm) at the time of the positive, however he indicated he had some trouble with the sampling station at the time of sampling and it may have become contaminated. He replaced the sample station prior to collecting the repeats. Rene emailed Thurs. 8/15/19 and reported that all three repeats were absent for coliform. I reminded him to report the repeat results to us by 8/24/19. No further action required at this time.
