66--HydroTech ZS Long-Term Deployment Modules and Acce

The U.S. Geological Survey, Louisiana Water Science Center, plans to issue a non-competitive purchase order to HydroTech ZS Consulting of Round Rock, TX, for Long-Term Deployment Modules and associated accessories designed to prevent biofouling on water quality sensors. These modules are uniquely configured to interface with the In-Situ AquaTroll 200 and YSI EXO3 sensors currently in use at coastal monitoring stations, and no other commercially available product meets the technical requirement of evacuating an air chamber around sensor probes to inhibit fouling, making HydroTech ZS Consulting the only viable source. Delivery is required within 90 days of award to Baton Rouge, LA, under a firm fixed-price agreement, with an anticipated award date of September 1, 2026. The acquisition is being conducted under authority that permits non-competitive award due to sole-source justification, and while responses may be submitted for informational purposes, no formal competition is intended. The solicitation number is 140G0126Q0221, the NAICS code is 334519 with a size standard of 600 employees, and vendors must be registered in SAM.gov to be eligible for award. All submissions must be emailed to Cynthia Nicanor with the specified subject line reference by the response deadline of August 7, 2026.
