Technical and Administrative Support to the U. S. Environmental Protection Agency

The EPA Office of Water established a Master IDIQ on March 31, 2020 supporting technical and administrative services across its five major divisions: Immediate Office, Office of Groundwater and Drinking Water, Office of Science and Technology, Office of Wetlands, Oceans, and Watersheds, and Office of Wastewater Management. Ordering closed on March 31, 2025; the vehicle is no longer available for new task orders.

Twenty-three task orders have been awarded since vehicle inception, with $14.9 million in combined potential value and $11.5 million obligated (77% spend-down). The solicitation advertised this as a multiple-award small-business set-aside, but actual awards split between small-business and unrestricted designations. Across the portfolio, 61 percent of orders carry no set-aside (14 orders), and 39 percent are small-business awards (9 orders). Activity peaked in 2022 (8 orders) and 2024 (7 orders), with a single order in the final ordering window (February 2025).

Horsley Witten Group, Inc. dominates the vehicle, holding 14 of 23 awards with $8.5 million in combined potential value. Avanti Corporation follows with 7 orders and $6.1 million combined value. Great Lakes Environmental Center, Inc. holds 2 orders worth $313 thousand. These three primes capture 100 percent of activity.

The EPA Office of Water funds 22 of 23 orders (valued at $14.6 million combined potential); EPA Region 2 placed a single order. Work spans water-quality standards support, lead service-line inventories and replacement, rural and tribal wastewater infrastructure assistance, endangered species act consultation on NPDES permits, climate-ready estuary assessments, and national aquatic resource surveys. Recent orders (through February 2025) include support for lead service-line inventories ($567 thousand and $700 thousand ceilings), water-quality standards academy ($139 thousand ceiling), and rural wastewater infrastructure ($146 thousand ceiling). The largest single order was a lead service-line support task valued at $3.7 million potential (December 2022). Task order durations typically range from eight months to two years. All awards use Cost Plus Fixed Fee or Cost Plus Award Fee pricing, with occasional Firm Fixed Price structures.

The United States Environmental Protection Agency (EPA) Office of Water (OW) technical and administrative contractor support to span across OW's Immediate Office (IO), Office of Groundwater and Drinking Water (OGWDW), Office of Science and Technology (OST), Office of Wetlands, Oceans, and Watersheds (OWOW) and Office of Wastewater Management (OWM). This contract may also support the efforts of other EPA offices when activities intersect with OW Programs.
