The contract is a commercial item procurement under solicitation number 75H71026Q00175, with a 120-day performance period from the date of award, estimated to run from July 1, 2026, to October 31, 2026. The work requires full site assessment, drilling of each well to a depth of 40 to 50 feet, installation of all necessary equipment, provision of one year of post-installation monitoring data for the Navajo Nation Environmental Protection Agency, and submission of site documentation including photos and a detailed installation timeline. The contractor must furnish all tools, materials, equipment, and personal protective equipment, and must comply with EPA, Navajo Nation EPA, and NFPA standards, along with applicable federal environmental and safety regulations. The solicitation is a total small business set-aside under FAR 19.5 with NAICS code 541330 and requires all offerors to be registered in SAM and meet socioeconomic representation requirements, including eligibility for Indian Economic Enterprise, Service-Disabled Veteran-Owned Small Business, and HUBZone concerns. Proposals must be submitted in four organized volumes by June 16, 2026, at 5:00 p.m. MST, in PDF format, with strict separation of administrative, technical, past performance, and pricing information. Technical capability and demonstrated experience with at least three similar projects in the last three years are mandatory pass/fail gates; failure to meet these renders proposals unacceptable.
