Who Was Contacted and Phone: John Handler (503) 801-0905
Contact Date: 10/08/2007
Contacted By: SALIS, KARI (DWP)
Contact Method/Location: Office
Reasons: Coliform
Details: SUMMARY: TC+ response - invalidate DETAILS: John called and talked to Tom Charbonneau on 10/5. They had a TC+ FC- sample and collected 4 repeats (only 3 required). On Monday, the repeats results were TC+ from the original sample site, and TC- from all 3 other repeats. The sample station that they use at that sample site is a different design than all the other sample stations. This one cannot be cleaned. They are taking apart this sample station and taking photos. John feels that this was the cause of the TC+. He has ordered another sample station like all the others. He will make a temporary sample pipe to sample straight from the main. I told him this sounded like good reason to invalidate the samples. He will send me a write up of what happened and what they did, and I will write up the invalidation. He will be sure to collect another routine for October. ACTION NEEDED: invalidate routine sample 10/4/07, and repeat 10/5/07.
