About this file
The document is a Salient Characteristics specification for a Water Sampling System (S25034) detailing technical requirements for a comprehensive water sampling equipment set. The system includes five key components: a Variable Frequency Drive (VFD), a cord, a reel, a hose, and a pump, each with precise technical specifications. Critical requirements include a pump capable of operating at depths to 275 ft, providing flow rates from 8 GPM to 100 ml/min, housed in a NEMA 4X enclosure, operating across -20 to 50 C temperatures, and powered by a 230V Single-Phase AC source.
The related federal contract opportunity is a small business set-aside solicitation (RFQ 140G0125Q0107) issued by the U.S. Geological Survey Nebraska Water Science Center for one Water Sampling System. The procurement timeline includes a quote request on 3/31/2025 with written quotes due 4/7/2025 at 08:00 AM ED, and an anticipated contract award date of 4/17/2025. Vendors must be registered in SAM.gov, fall under NAICS code 333914 with a 750-employee size standard, and submit responses via email to jwalsh@usgs.gov. The system will be delivered to the Nebraska Water Science Center in Lincoln, NE, within 30 days after order receipt.
