Eastern Research Group Inc.

Eastern Research Group Inc., doing business as Erg, Inc., is a for-profit Subchapter S Corporation headquartered in Concord, Massachusetts, that delivers environmental consulting, regulatory support, technical analysis, laboratory services, and program management to federal civilian agencies as a prime contractor on 99% of its award footprint. The company holds no small-business set-aside certifications and competes in full-and-open procurements across government-wide vehicles and agency-specific contracts.

Eastern Research Group's customer base is heavily concentrated in environmental regulatory work. The Environmental Protection Agency dominates by funding value—the EPA Office for Air and Radiation alone accounts for $7.22 billion in combined potential value across 629 awards, while the EPA's Office for Water, Office of Research and Development, and Office of the Administrator collectively represent another $1.42 billion. The Department of the Navy's Naval Sea Systems Command anchors $10.28 billion across 77 awards, driven by large single task orders for explosive ordnance disposal and specialized technical support rather than routine environmental work. By award count, the EPA (across all offices) represents roughly 50% of recent activity, followed by the Department of Labor's Occupational Safety and Health Administration (348 awards, $178 million), establishing ERG as a specialized environmental and occupational safety consulting firm with secondary exposure to defense technical support.

Concrete capability framing derives from work named in recent awards. ERG delivers emissions testing and characterization (National Hazardous Air Pollutants Support contracts, air quality monitoring for the TEMPO satellite mission); hazardous air pollutant analysis and regulatory support (Clean Air Act rulemaking, NESHAP technology reviews); water quality and wastewater treatment technical services (NPDES permit support, wastewater treatment lagoon and treatment plant optimization); laboratory analysis services (volatile organic compounds, fine particulate matter, inorganic bioavailability testing, microbiology support at EPA's Research Triangle Park facility); per- and polyfluoroalkyl substances (PFAS) source characterization and thermal destruction research; conflict resolution and stakeholder facilitation for Superfund sites and environmental collaboration initiatives; regulatory economics and cost-benefit analysis for air and water rulemaking; occupational safety and health technical support to OSHA; and specialized technical research support for EPA's Office of Research and Development. Representative prime contracts include a $425.8 million Technical and Outreach Support Services BPA with EPA's Office of Air and Radiation (November 2024–November 2029) for air quality, emissions, and regulatory support; a $100 million STREAMS V on-site research laboratory support contract with EPA's Office of Research and Development (January 2026–January 2033) providing approximately 91,000 hours annually of technical and laboratory services at Research Triangle Park; a $100 million OLEM Mission Support Services BPA (September 2024–September 2029) for waste management, remediation, and emergency response technical support; and a $75.5 million EPA Region 7 Enforcement, Litigation, and Technical Skill Support BPA (June 2026–June 2031) for enforcement case support and inspections. Additional significant vehicles include a $42 million Chemicals, Coatings, and Commerce Sectors Regulatory Support Services BPA (January 2025–December 2029), a $20 million Technical Evaluation and Market Assessment Support BPA for water conservation and reuse programs (December 2025–December 2030), and an $85.26 million Environmental Collaboration and Conflict Resolution Services contract supporting EPA Community Advisory Groups at Superfund sites nationwide.

GSA Schedule 70 labor rates span 93 categories from $45.12/hr (Data Processing Specialist 1) to $330.22/hr (Principal Consultant 2), with median government-paid rates around $139.88/hr and senior technical leadership pricing through $405/hr. Education requirements range from high school diploma through master's degree; no security-cleared positions are offered. This rate spectrum reflects a workforce capable of delivering entry-level administrative support through senior technical and project management expertise.

ERG operates as a prime contractor on substantially all delivery, conducting work in-house with minimal subcontractor engagement. Across SCI-reportable prime service contracts, the average sub-hours share is 3%, with 109 named subcontractors reported over the period. When subcontracting occurs, partners have included Science Systems and Applications Inc. (a woman-owned small business providing atmospheric chemistry and PFAS research support), Serco Inc. (metrology and calibration support), Forum Facilitation Group LLC and Consensus Building Institute Inc. (alternative dispute resolution and Superfund site facilitation), and Triangle Associates Inc. (environmental conflict resolution). Sub-engagement is selective and task-specific rather than structural.

SCI-reported invoicing shows growth trajectory across FY2022–FY2025: FY2022 recorded $62.9 million across 224 FTEs; FY2023, $73.6 million across 241 FTEs; FY2024, $104 million across 346 FTEs; and FY2025, $123.9 million across 373 FTEs. SCI captures only federal service contracts above $150,000 and excludes goods, products, and non-federal revenue; these figures are a strict subset of the vendor's total federal activity and a smaller subset of enterprise revenue. The 67% increase in invoiced amount from FY2022 to FY2025, paired with a 67% increase in FTE count, indicates proportional capacity growth supporting larger delivery orders and sustained utilization of existing IDVs.

Vehicle position is dominated by the Multiple Award Schedule (381 task orders, $7.71 billion combined potential value), the OASIS+ Unrestricted IDIQ (unlimited ceiling, multiple awards, December 2024–December 2029), and the OASIS+ Total Small Business Set-Aside IDIQ (unlimited ceiling, despite ERG holding no small-business certifications). These represent government-wide vehicles with substantial ordering authority across federal civilian and defense agencies. Agency-specific vehicles include EPA BPAs and IDIQs accounting for over $1.6 billion in aggregate ceiling value, with task-order activity concentrated in air quality, water resources, research laboratory support, enforcement, and conflict resolution domains. The Mission Oriented Business Integrated Services vehicle carries 412 task orders valued at $110.4 million, indicating regular use for logistics and professional services.

Activity trajectory shows declining award volume in the most recent year: FY2022 and FY2023 each recorded 135 awards, FY2024 climbed to 174, but FY2025 dropped to 102 awards, and FY2026 (through October 15) shows only 83 awards year-to-date. Combined potential value across all 4,413 awards in the source totals $22.59 billion, with only $1.61 billion obligated (7% draw-down), indicating a large portfolio of available contract ceiling with modest initial obligation rates typical of indefinite-delivery vehicles. The recompete cliff window (next 24 months) presents 139 awards with combined potential value of $349.3 million reaching ultimate completion, exposing ERG to recompete risk on established EPA technical support vehicles, water programs, and regulatory support contracts.

Category concentration aligns with capability framing: Environmental Consulting Services (1,498 awards), Administrative Management and General Management Consulting (539 awards), and All Other Professional, Scientific, and Technical Services (301 awards) dominate the NAICS footprint. By PSC code, Support-Professional: Other (986 awards), Other Environmental Services (405 awards), and Special Studies/Analysis-Environmental Assessments (363 awards) lead. This classification consistency confirms ERG's positioning as a specialized environmental consulting and program management firm with no material product or goods delivery.

Recent large-value awards and modifications underscore sustained demand: a $99.9 million Naval Sea Systems Command continuation order for explosives manufacturing support (July 2026, Indian Head, Maryland); a $6.025 million EPA Office of Chemical Safety and Pollution Prevention order for occupational exposure and environmental release assessments and economics support (December 2024–December 2027); a $5.93 million EPA PFAS source emissions measurements and characterization delivery order (December 2025–December 2028); and a $3.6 million EPA Clean Air Act stationary source and mobile source emissions enforcement support BPA call (September 2026–March 2029). These awards reflect ERG's entrenchment in EPA's technical infrastructure and sustained performance on critical environmental and occupational safety programs.
