About this opportunity

Written by GovTribe AI · Oct 9, 2025

The US International Boundary and Water Commission (USIBWC) is seeking laboratory services for the Tijuana River Valley Monitoring Program (TRVMP), a comprehensive water quality monitoring program required under NPDES permit CA0108928 for the South Bay International Wastewater Treatment Plant. The contract requires laboratory analysis of water and sediment samples from seven monitoring locations along the Tijuana River and adjacent canyons, including testing for bacteria, metals, pesticides, organic compounds, and other environmental indicators. Contractors must maintain California Environmental Laboratory Accreditation Program (ELAP) certification or federal NELAC accreditation and provide services on an "all or none" basis across multiple contract line items. The government requires strict adherence to Quality Assurance/Quality Control requirements including sample hold times, with no acceptance of qualified data. Proposals are due October 15, 2025, at 3:00 PM MDT, with questions having been accepted until September 11, 2025, and quotes must remain valid for 90 days.

This procurement is set aside for small businesses under NAICS code 541380 with a size standard of $19.0 million, and only SAM-registered small businesses with active UEI numbers will be considered. The incumbent contractor is EGC-AGEISS LLC, which held the previous contract valued at $1,712,572.09. The contract structure includes a base year (FY 2026) and four option years (FY 2027-2030), with services scheduled from October 1, 2025, through September 30, 2030, for a potential total duration not exceeding 66 months. The sampling program encompasses weekly bacteria testing at one location, quarterly river water sampling, biennial sediment testing, annual wet weather event sampling, and variable dry weather transboundary event analyses across all seven monitoring stations. All work will be performed in San Diego County, California, specifically in the Tijuana River Valley and transboundary canyons along the US-Mexico border.

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.

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.
