Confined Aquifer Sustainability Study

The Colorado Department of Natural Resources Division of Water Resources has issued a Notice of Proposed Sole Source for a Confined Aquifer Sustainability Study, solicitation number NPSS1-PEAA-2027000051-1. The agency intends to award a sole source contract to HRS Water Consultants, citing their extensive experience in groundwater and hydrogeology within Division 3 and their ability to meet critical deadlines that other firms could not achieve without significant additional time and expense. The project has an approximate budget of 249,950 dollars and a performance period ending June 30, 2029. The scope of work requires a consulting firm specializing in hydrogeology and the Rio Grande Decision Support System to model inflows and outflows of the Confined Aquifer System and estimate water levels and artesian pressures from 1978 through 2000. Key deliverables include the completion of the sustainability study by September 30, 2028, a draft report due by October 31, 2028, and a final report due by March 15, 2029. While this is a proposed sole source award, other vendors may challenge the status by submitting a one-page cover letter demonstrating their capabilities to Jeanette Stroud by the response deadline of September 15, 2026.
