Lab Services TRVMP

Response to question received: Q-The 8-hour holding time specified in 40 CFR Part 136 and the project QAPP may not always be achievable since samples are collected by the USIBWC San Diego Field Office and shipped overnight to the laboratory. Can you please confirm if the Government will accept results analyzed beyond the 8-hour limit, as long as the exceedance is clearly documented and qualified in the report? IBWC cannot accept data with qualifiers for QA/QC requirements. All proposals must be able to meet stated QA/QC requirements including for sample hold times.

Note: Bidders may bid an option to conduct the sampling.

Due date extended to October 15, 2025 at 3PM MDT. CLINS 002, 004, 006, 008, and 010 are no cost receiving lines.

Question received : I believe there is conflicting information on whether microbiology sampling will only be at one station OR at all seven starions. Can you clarify?

Response: Weekly fecal coliforms and E. coli will be collected at the TRV-1 (Dairy Mart Bridge) site only All other sampling schedules will also analyze for Fecal and E.coli (except TRV-7 which will test for enterococcus) and for norovirus and enterovirus. That would be during the quarterly water samples in the river, once per year wet weather flow at all locations, and any dry weather transboundary events collected.
