About this vehicle
EPA Region 7 awarded this Master IDIQ for environmental consulting services in Superfund and emergency response on July 15, 2019, with a shared ceiling of $132.253 million; ordering closed on July 14, 2024, and the vehicle is no longer available for new task orders.
The vehicle contracts technical assessment and response support across Superfund sites, removal actions, remedial investigations, site assessments, emergency response (oil spills, hazardous releases, disaster recovery), and lead-removal programs. Recent task orders show work spanning site characterization, removal assessments and actions, monitoring, sampling, and on-scene coordinator support. A $50 million task order for the 2025 Southern California wildfires represents the largest single obligation; smaller routine orders typically range from $16,000 to $400,000 with firm fixed-price or time-and-materials pricing. Most task orders carry performance periods through mid-2026.
Four prime contractors hold all 507 awarded orders. Weston Solutions Inc. dominates by potential value at $108.6 million across 126 orders, followed by three separate Tetra Tech, Inc. entities totaling $189.4 million combined potential value across 381 orders. The Tetra Tech portfolio is fragmented across three contractor codes but appears to represent the same parent entity. Competitive concentration is high: the top two prime groupings account for substantially all work under the vehicle.
EPA Region 9 places the most orders by dollar value at $108.6 million (36% of total), with Region 7 at $41.1 million (14%), Region 5 at $118.4 million (40%), and Region 4 at $29.9 million (10%). The vehicle funds a multi-region mission, though ordering is geographically dispersed across Superfund sites nationwide and in US territories including Guam, American Samoa, and the Northern Mariana Islands.
All 507 orders carry unrestricted (no set-aside) status. Combined task-order potential value is $298.1 million, with $296.1 million already obligated (99% utilization). Since ordering closed in July 2024, this vehicle is archived. Ordering activity declined sharply in 2025 (24 orders) and continued declining into 2026 (7 orders through mid-June), reflecting the approaching contract end.
