Reasons: Coliform
Details: SUMMARY: Routine +TC DETAILS: On Thursday 10/9/14 Jennifer reported that a routine sample collected Wednesday 10/8/14 at 12797 SW Da Vinci Ln came back positive for total coliform/absent for E. coli. This is the same site that was positive about a month ago-- this is an area where they struggle to maintain a detectable chlorine residual. Three repeats were collected today (upstream, downstream, and original site), as well as a triggered raw water sample from the only well in operation at the time, Well #2. ACTION NEEDED: No further action needed at this time, will wait for repeat monitoring results Friday and respond accordingly. Discuss further w/ system ways to maintain a detectable chlorine residual in this part of the system.
