Environmental Research Group, L.L.C.

Environmental Research Group, L.L.C. Company Headquarters Division, doing business as Environmental Research Group LLC, is a women-owned small business and SDVOSB prime contractor headquartered in Baltimore, Maryland, delivering environmental consulting, cultural resource management, and compliance support services to the Department of Defense, Army Corps of Engineers, and civilian agencies through 430 prime awards worth $349.1 million combined potential value. The vendor operates under SBA certifications including Women-Owned Small Business, Service-Disabled Veteran-Owned Small Business, Small Disadvantaged Business, and 8(a) status, competing predominantly full-and-open and through set-asides across both sole-source and competitive vehicles.

Environmental Research Group's concrete capability footprint centers on environmental compliance and remediation, archaeological and cultural resource surveys, NEPA environmental assessments, RCRA and SPCC regulatory support, historic preservation Section 106 compliance, hazardous materials assessment, wetland delineation, and biological field services. Representative prime work includes a $4.9 million 8(a) Sole Source definitive contract with the Northeast Region Defense agency for environmental support services at Fort Knox, Kentucky (ultimate completion June 30, 2024); a $7.5 million single-award indefinite delivery contract with the Army Installation Management Command Southeast Region for RCRA and SPCC compliance support at Fort Campbell, Kentucky through September 2028; a $5 million single-award SDVOSB-set-aside BPA with the Department of Veterans Affairs Office of Construction and Facilities Management for historic preservation and NEPA consulting services through March 2027; and a $5 million single-award BPA with the Western Area Power Administration for biological support services in the Sierra Nevada Region through September 2030. Recent task orders include a $1.35 million Woman-Owned Small Business set-aside delivery order from the Defense Logistics Agency's Southeast Region for RCRA and SPCC compliance at Fort Campbell (ultimate completion March 31, 2027) and a $578,035 Total Small Business set-aside delivery order from the Department of Defense's Baltimore office for natural resource surveys supporting Integrated Natural Resources Management Plans (ultimate completion September 28, 2028).

Customer concentration is heavily weighted toward Army Installation Management Command and Army Corps of Engineers operations. The top five customer organizations by award count account for 47% of all awards: the Army Corps of Engineers Engineering District Norfolk leads with 61 awards ($17.4 million combined potential value), followed by Army Installation Management Command Northeast Region (54 awards, $70.7 million), Naval Facilities Engineering Command (42 awards, $12.9 million), Army Corps of Engineers Engineering District New Orleans (30 awards, $13.4 million), and Army Corps of Engineers Headquarters (18 awards, $24.2 million). By dollar value, the ranking reflects a similar pattern: Army Installation Management Command Northeast Region anchors the portfolio at $70.7 million across 54 awards, with Army Installation Management Command Headquarters contributing $26.1 million (15 awards) and Army Corps of Engineers delivering $24.2 million (18 awards). The vendor has served 64 distinct customer agencies over the period covered in the source, indicating broad federal agency penetration despite Army-family customer concentration.

The vendor's vehicle posture is multi-pronged and agency-specific. The Multiple Award Schedule (MAS) is the primary vehicle, with 82 task orders valued at $47.8 million combined potential value, used across Army, Navy, VA, DEA, FEMA, Department of Interior, and Department of Agriculture customers. Additionally, Environmental Research Group holds several large single-award indefinite delivery contracts: a $4.5 million 8(a) Sole Source IDC with the Army Corps of Engineers for environmental, compliance, and base support services (63 task orders, $6.5 million combined value); a $4.5 million 8(a) Sole Source IDC with the Army for comprehensive environmental services (performance varied across Fort Meade, Fort Knox, Anniston, and others); a $4 million EDWOSB single-award IDC with the Army Corps of Engineers for forensic disinterments and analysis services through May 2029 (16 awards at $578,035); and a $3.31 million Woman-Owned Small Business single-award IDC with the Army Corps of Engineers Little Rock District for non-personal archaeological and cultural resource surveys through September 2027 (2 task orders, $1.05 million to date). The vendor also maintains smaller BPA vehicles with NRCS ($360,000 ceiling, 4 task orders), USDA Southeast Region for Puerto Rico and Caribbean archaeological work ($2 million ceiling, 2 task orders), and the DEA ($4.5 million ceiling, multiple task orders).

Activity has declined from 37 awards in 2022 to 9 awards through May 2026, suggesting maturation from high-volume task-order execution to larger, longer-duration engagements. Nineteen awards (combined potential value $9.7 million) complete within the next twenty-four months, representing recompete exposure in environmental compliance, archaeological, and biological support categories across Army and Navy installations.

Environmental Research Group operates as a prime contractor on 99% of awards; subcontract footprint is minimal at 1% (6 sub-awards). Named primes using Environmental Research Group as a subcontractor include Eastern Research Group Inc. for construction and grant management evaluation support under water permits programs (3 sub-awards, 2023–2026), Specpro Sustainment and Environmental LLC for coastal national park infrastructure adaptation planning, Vintun LLC for Army Enterprise Environmental and Disposal Liabilities support, and HDR Environmental for environmental impact statement technical support on the T-38 recapitalization. SCI-reported invoicing across FY2022–FY2024 totals $1.4 million with median government-paid rates of $144.09/hr (10th percentile $53.19/hr, 90th percentile $369.87/hr), corresponding to field and senior technical roles. Average sub-hours share across prime contracts is 8%, indicating the vendor builds most delivery teams in-house. The vendor's GSA Schedule labor portfolio offers 13 categories spanning GIS specialists at $48.14/hr through program managers at $126.61/hr, with no security-cleared roles listed.

Corporate structure includes five named joint-venture subsidiaries: Erg-Phe JV LLC, Erg-Terracon JV LLC and Erg-Terracon Jv2 LLC (both carrying SDVOSB and WOSB certifications), Erg-Hana JV LLC, and Pherg JV LLC. The joint-venture structure across multiple partners signals capacity expansion and specialized teaming for larger prime awards, particularly in environmental remediation and archaeological disciplines where Environmental Research Group leverages partner expertise under the parent's small business certifications.
