Weston-Techlaw JV LLC

Weston-Techlaw JV LLC, a for-profit joint venture headquartered in Chantilly, Virginia, operates as an environmental remediation and site investigation contractor delivering specialized scientific and engineering services to the Environmental Protection Agency's Superfund program and emergency response missions across the United States, competing exclusively on full-and-open, non-set-aside task orders.

The joint venture is the sole awardee on the EPA's Environmental Response Team (ERT) Indefinite Delivery Contract 68HE0321D0001, a $105.6 million single-award vehicle running through July 2027 that enables rapid EPA procurement of technical expertise for contaminated site characterization, remediation design, groundwater and air monitoring, vapor intrusion sampling, drilling support, and compliance activities at Superfund locations nationwide. Recent representative work includes a $1.07 million task order for Southern California Wildfires environmental response (awarded February 2025), a $2.25 million hydrogeological assessment and site characterization engagement at the Selma Wood Treating Company site in California (awarded September 2023), a $23 million Core Response Team staffing task order supporting EPA regional emergency response infrastructure (awarded August 2022), and a $1.24 million geospatial product development and data management engagement (awarded March 2023). Weston-Techlaw has issued 92 task orders totaling $56 million in combined potential value under the ERT parent vehicle, with place of performance spanning Chantilly, Virginia (administrative and operations hub), Edison, New Jersey (laboratory and field support), and project-specific Superfund sites across EPA regions.

Customer concentration is complete: the EPA's Office of Land and Emergency Management funds 74 awards (96% of total awards) carrying $159.6 million in combined potential value. Regional EPA offices—Region 2, Region 3, Region 9, Region 8, and Region 1—place the remaining awards at substantially smaller dollar magnitudes ($51 thousand to $828 thousand per region). Across FY2022 through FY2025, Weston-Techlaw has delivered work under 78 SCI-reportable federal service contracts above the $150,000 threshold, invoicing $25.1 million and scaling from 2.6 FTEs in FY2022 to 15.5 FTEs in FY2025. On these SCI-reportable prime contracts, government-paid hourly rates centered on a median of approximately $114.43 per hour, with senior technical labor pricing to $326.24 per hour and entry-level support at $83.59 per hour. The company operates predominantly as a self-performer: across SCI-reportable prime contracts, subcontractors performed roughly 1% of total contractor hours, with named subcontractor engagement limited to specialized drilling (Cascade Drilling, L.P., Betts Drilling, Inc.), waste management (Environmental Waste Minimization, Inc.), water quality monitoring and modeling (Integral Consulting Inc.), data validation (Environmental Data Services, LIMITED), and modular building services (Pacific Mobile Structures, Inc.).

Forty-four awards totaling $47.7 million in combined potential value reach ultimate completion within the next twenty-four months, representing significant recompete exposure. All 93 recent awards carry primary NAICS 541620 (Environmental Consulting Services) with secondary classification under PSC 15 (Environmental Systems Protection—Environmental Consulting and Legal Support) and PSC 15 (Environmental Systems Protection—Environmental Remediation). Weston-Techlaw operates as a 100% prime contractor footprint; no sub-award activity appears in the source data.
