1112134 10/11/2022 Deficient Monitoring The October Effluent sample was received in good condition at the BSK San Bernardino satellite laboratory on 10/11/2022 and logged in by BSK-RAL for Cyanide testing. The sample was then shipped overnight to the BSK Fresno main laboratory. However, a Facility Code in the transit chain-of-custody was inadvertently left out for the Cyanide testing, thus failing to designate the Cyanide test to be performed by BSK-FAL, instead of BSK-RAL. Consequently, even though the sample arrived at BSK-FAL on 10/12/2022, and the Laboratory Information System (LIMS) had a Cyanide test logged in for the sample, the test did not show up amongst the worklists to be performed by the Wet Chemistry department at BSK-FAL. By the time this login error was discovered, the sample container was already disposed and the sample had already passed the 14 days holding time for Cyanide testing. When BSK notified us, it was too late to resample. There were no reported results for Cyanide in the month of October. Violation N eSMR Simi Valley WQCP 427894 R4-2019-0135 N
