The Department of Defense, specifically the U.S. Army Corps of Engineers (USACE) Seattle District, is seeking to award a sole-source contract for Water Quality Analytical Services to the Institute for Environmental Health (IEH) located in Seattle, Washington. The contract aims to ensure that nutrient data from water samples meet strict reporting limits and comply with EPA holding times, which is critical for long-term comparison studies required by the project. The IEH laboratory has a proven track record of analyzing nutrient data for the Seattle District since 2006 and for the Kootenai Tribe since the early 2000s, making it uniquely qualified for this task. Interested firms that believe they can meet the requirements are encouraged to submit supporting documentation to the primary contact, Tyler Luke, at tyler.j.luke@usace.army.mil, as this procurement will follow FAR Part 12 and FAR Part 13 procedures.
