Water Advisory Details

PWS ID: OR41 06169
Advisory Type: Boil Water
Reason: E. coli, Confirmed in Distribution
Area Affected: System-wide
Affected Populations: All
Begin Date: Aug 24, 2018
Date Lifted: Open
Contacted By: BAIRD, GREGG (DWP)
Who Was Contacted: Katie Ryan
Contact Phone: 503-892-2782
Details: A routine sample collected 8/22/18 came back positive for both total coliform and E. coli. Combined with the fact that a routine sample collected earlier in the month on 8/7/18 was positive for total coliform, and a recent history of unresolved total coliform detections in July, the system is required to issue a boil water notice at this time. A level 2 investigation has also been triggered which requires a site visit prior to 9/21/18. I asked Katie to verify that a chlorine residual is being detected out in the distribution system, and to collect 3 repeat samples as soon as possible and report the results by 9/2/18. I sent her the public notice template and asked her to edit it, post it, and send me a copy.

Associated Alerts: COLI18109 - 08/17/2018 - COLIFORM, TOTAL (TCR)

COLI18130 - 08/24/2018 - COLIFORM, E. COLI , COLIFORM, TOTAL (TCR)
