About the company
GSI Mid-Atlantic, Inc., a Subchapter S corporation based in Bel Air, Maryland, operates exclusively as a subcontractor delivering environmental remediation and drilling services to federal agencies under prime relationships with large engineering firms. The vendor holds no prime contracts or government-wide vehicles; all four federal awards in the source carry active work perform under AECOM Technical Services and EA Engineering, Science, And Technology, Inc. as primes, distributed across environmental remediation, groundwater investigation, and drilling service scopes.
GSI Mid-Atlantic serves three federal customers with relatively equal weight by award count. The Department of the Army Corps of Engineers Engineering District Baltimore accounts for two awards under the USACE Multiple Award Environmental Services 2017 contract vehicle; the Environmental Protection Agency Region 3 placed one award under the EPA Remedial Acquisition Framework for Design and Engineering Services; and the Department of the Navy Naval Facilities Engineering Command issued one award under indefinite delivery contract N6274217D1800. All four awards total $420 thousand in combined dollars obligated.
The vendor's subcontract work focuses on groundwater investigation and remediation services. Recent representative work includes a July 2024 sub-award from EA Engineering for groundwater sampling and geoprobe drilling at the Georgetown North Groundwater Superfund Site, completing the remedial investigation and feasibility study phase, and two drilling-service sub-awards from AECOM — one from February 2024 supporting comprehensive environmental response, compensation, and liability act remediation at Fort George G. Meade, Maryland, and one from July 2023 for land use controls and community involvement drilling services at Joint Base Andrews-Naval Air Facility Washington. Award activity has been sporadic — one award in 2021, a gap in 2022, one in 2023, and two in 2024 — generating minimal transaction volume in the source data window and indicating marginal scale relative to its prime partners.
