Details: SUMMARY: Routine +TC DETAILS: Jennifer called to report that a routine sample collected on Tuesday the 16th at 7110 SW Fir Loop came back positive for total coliform (e.coli absent). She suspects the cause may be a reservoir with low turnover. Free chlorine residual for the sample was low at 0.12 ppm. She indicated that 3 repeats would be collected today (upstream, downstream, and from original site), as well as 2 triggered source water samples from ASR1 and Well 2 since they are active. ACTION NEEDED: No further action needed at this time-- will wait for results of repeats and respond accordingly.
