MEGA for Sites Containing Chemical Warfare Material

The Department of the Army Corps of Engineers Engineering Support Center Huntsville awarded the Master IDIQ "MEGA for Sites Containing Chemical Warfare Material" on December 28, 2016, with a shared ceiling of $400 million and ordering authority through December 26, 2021. Ordering closed more than four years ago; this vehicle is no longer active for new task orders.

The vehicle executed 79 task orders over a five-year period, with peak activity in 2017 and 2018 (29 and 20 orders respectively) before declining sharply to 3 orders in 2020 and 2 in 2021. Combined task-order potential value reached $413.7 million, with $372.2 million already obligated (90 percent). The most recent task-order award occurred on August 31, 2021.

Work encompasses environmental remediation services under the Defense Environmental Restoration Program (DERP), Formerly Used Defense Sites (FUDS), Military Munitions Response (MMR) for conventional and chemical warfare materiel, environmental compliance, EPA Superfund and Brownfield support, and environmental stewardship across military installations and interagency sites. Task orders span remedial investigations, feasibility studies, interim measures, removal actions, construction support, facility demolition, and specialized services such as aqueous film-forming foam (AFFF) replacement and per- and polyfluoroalkyl substances (PFAS) validation studies.

Hydrogeologic, Inc. dominates the awardee base, holding 33 of 79 orders with $224.7 million in combined potential value—roughly 54 percent of total vehicle activity. Parsons Government Services Inc. follows with 17 orders and $82.9 million. USA Environmental, Inc., Aptim Federal Services, LLC, and AECOM Technical Services, Inc. collectively account for the remainder. The top five primes capture 99 percent of combined potential value.

The Department of the Army Corps of Engineers Engineering Support Center Huntsville placed 67 of 79 orders ($235.3 million combined potential value). Two additional Army organizations—Installation Management Command Headquarters and Installation Management Command Northeast Region—placed 6 and 2 orders respectively, totaling $171.1 million. Remaining orders funded EPA and other agencies.

Ninety-two percent of task orders carried no set-aside; six orders (8 percent) were designated Total Small Business. Task-order ceilings ranged widely, from minimum guarantees of $3,000 to mega-orders exceeding $49 million. Notable large awards included remediation and demolition of Aberdeen Proving Ground facilities ($49.9 million), interim measures at Redstone Arsenal ($39.7 million), and investigation and remediation at multiple sites ($31.2 million). Typical smaller task orders ranged from $400,000 to $5 million. Performance occurred across domestic military installations, including Alabama, Kentucky, Maryland, Arizona, Puerto Rico, and other locations; work also extended to overseas sites including Pacific islands.
