PWS ID: OR41 00030
Advisory Type: Boil Water
Reason: E. coli, Confirmed in Distribution
Area Affected: System-wide
Affected Populations: All
Begin Date: Oct 15, 2020
Date Lifted: Oct 23, 2020
Who Was Contacted: Greg Mustoe
Contact Phone: 541-220-5041
Details: Contact report from 10/15 "Talked to Greg, he already issued boil notice. Greg is aware that a level 2 investigation will be required, planning to schedule next week. Greg is aware that he needs to take 5 confirmation samples from the well that was positive." 10/16 Talked to Greg and he took the 5 confirmation samples yesterday and is planning on turning them into the lab today. After he pulled the samples he shocked the system. I asked him to send us a copy of the Boil Notice.

Update 10/15/2020:  Spoke with operator following 5 positive confirmation samples. Informed operator that in order to continue use of well #1 they will need a source evaluation done by the state to determine how to move forward. I sent the form to Shawn this morning. Level 2 investigation will be done tomorrow morning.

Lifted 10/23/2020:  Talked to Greg, he said that they had negative repeats and source sample for well 2. He believes that the E.coli is out of the storage tank and distribution. He is aware that they must not use well 1 until further notice, and only use well 2.
