| Details: | SUMMARY: FC+ repeat result DETAILS: Yone called me at home on Saturday 6/20 to report that they got a FC+ at one of their "non-regulatory" sites taken on Friday 6/19. It is a line off of conduit #4 - actually the line is off of the pH meter feed line off conduit 4, that is why it is not considered a regulatory sample site. On Sunday, she called to let me know that the repeat was also FC+, but none of the other repeats were TC+ (upstream and downstream). Chlorine residual was normal, and no interuptions in treatment had occurred. On Sunday, they took a bunch of other repeats: on all conduits upstream and downstream of this sample site, inlet and outlet to powell butte, open reservoirs, etc. Since the same sample tap was positive and no others, I said the sample site could be invalidated. Any future samples from this location should be marked "special". ACTION NEEDED: document decision as necessary. | ||
