MSE Group LLC

MSE Group LLC, a subsidiary of Montrose Environmental Group, Inc., is an SBA-certified 8(a) small disadvantaged business headquartered in Orlando, Florida, that specializes in providing comprehensive environmental compliance, engineering, remediation, and construction services to federal agencies. The company was registered in SAM.gov in February 2011 and maintains its federal contractor registration. MSE Group serves as a prime contractor and subcontractor for the Department of Defense, General Services Administration, U.S. Forest Service, and other federal agencies, leveraging its expertise in environmental remediation, regulatory compliance, and facility management across military installations and federal properties nationwide.

MSE Group LLC has received extensive federal prime contract awards totaling millions of dollars across diverse environmental service categories. The company has executed major projects including a $24.8 million Phase I Remedial Investigation for Per- and Polyfluoroalkyl Substances (PFAS) at Hurlburt Field and Cape Canaveral Space Force Station in Florida, a $17.3 million PFAS remedial investigation at Patrick Space Force Base, MacDill Air Force Base, and Avon Park Air Force Range in Florida, and a $2.03 million delivery order for environmental compliance work at Marine Corps Base Camp Lejeune. Additional significant awards include a $3.59 million stormwater and fuel storage tank inspection contract for GSA Region 4 in Atlanta, Georgia, and multiple million-dollar contracts for environmental compliance technical support at Army Reserve facilities in Columbia, South Carolina. MSE Group's service portfolio encompasses waste stream determinations, EPCRA reporting, hazardous waste management planning, RCRA permit renewals, groundwater monitoring and sampling, environmental remediation oversight, stack testing for environmental compliance, long-term monitoring at post-remedial action sites, and environmental planning and assessment services. The company has provided these services across numerous Navy and Marine Corps installations including Kings Bay, Beaufort, Jacksonville, Mayport, Pensacola, Key West, Parris Island, Cherry Point, Albany, Guantanamo Bay, and other facilities, as well as Air Force installations and civilian federal properties. Funding agencies for MSE Group's awards include Naval Facilities Engineering Command, the U.S. Marine Corps, the U.S. Air Force Civil Engineer Center, the U.S. Army Reserve Command, the Navy Installations Command, U.S. Fleet Forces Command (Atlantic Fleet), and the General Services Administration. While most awards have been issued directly as prime contracts or delivery orders against existing IDIQs without small business set-asides, the company's 8(a) certification has positioned it favorably for awards from these federal agencies. MSE Group also serves as a subcontractor, including a 2022 subcontract with Cherokee Federal Solutions, L.L.C. for aboveground storage tank inspections at Marine Corps Base Camp Lejeune.

MSE Group LLC holds two significant federal contract IDVs that serve as primary vehicles for its ongoing work with federal agencies. The company maintains a $249 million Architect and Engineering (AE) Services indefinite delivery/indefinite quantity contract with the U.S. Army Corps of Engineers, South Atlantic Division, Mobile District, awarded in June 2021 with a completion date of June 8, 2026. This master IDIQ supports the Corps' Environmental Quality Program and provides services to military, civil works, and federal agency customers. Under this vehicle, MSE Group has received numerous task orders from the Department of the Air Force Civil Engineer Center, U.S. Marine Corps, U.S. Army Reserve Command, and the General Services Administration, with delivery orders ranging from hundreds of thousands to tens of millions of dollars for PFAS investigations, environmental compliance work, grease trap assessments, and other specialized environmental services. Additionally, MSE Group LLC holds a $50 million Blanket Purchase Agreement for Land Management Integrated Resources (LMIR) services awarded by the U.S. Forest Service in April 2024, with performance extending through March 2033. This multiple-award BPA was competitively awarded as a small business set-aside and positions MSE Group to provide a broad range of natural resources restoration, engineering, project management, and professional services across the United States. The company's IDV portfolio demonstrates its established relationship with federal agencies and its capability to execute large-scale, multi-year environmental and resource management initiatives at the national level.
