Water Advisory Details

PWS ID: OR41 94934
Advisory Type: Boil Water
Reason: E. coli, Confirmed in Distribution
Area Affected: System-wide
Affected Populations: All
Begin Date: Jul 20, 2019
Date Lifted: Jul 27, 2019
Contacted By: DOWNS, KENT (DWP)
Who Was Contacted: April Prestwich
Contact Phone: 602-363-0533
Details: On July 20, Ms. Prestwich emailed me stating that the lab confirmed repeat sample is EC+. The operator is currently shocking the tanks and passing out water and have called Bandon Well to inspect the system.

Lifted 07/27/2019:  Lab results for a triggered confirmation samples at SRC-BA were negative for coliform. [On 7/19, a triggered sample was mistakenly collected from the disconnected SRC-AA. But the 7/23 and 7/24 source samples are from the active source, BA.] A few days after the system had shock chlorinated the tanks and distribution, a special sample was collected from distribution lines on 7/23. This sample was negative, but the chlorine level was still quite elevated that day. By Friday 7/26, chlorine could no longer be smelled in the water (though no chlorine test kit). Betsy Parry of DWS communicated with system owner on Monday 7/29 to make sure they collect another distribution sample now that conditions have returned to normal (zero chlorine).

Associated Alerts: COLI19050 - 07/22/2019 - COLIFORM, E. COLI , COLIFORM, TOTAL (TCR)
