About this agency
Environmental Protection Agency Headquarters Offices is a civilian agency that procures environmental monitoring, laboratory services, technical analysis, and equipment through contracts, and funds grants supporting environmental compliance, water quality, workforce development, and community assistance programs.
The EPA awards contracts across a highly fragmented competitive base, with 10,501 distinct prime contractors and top-five concentration at 17 percent of recent award count. Over the last five years, Eastern Research Group Inc. leads by award volume with 319 awards and $567 million combined potential value, followed by ICF Incorporated, L.L.C. (241 awards, $272.2 million) and The Cadmus Group LLC (122 awards, $148.7 million). By potential value, General Dynamics Information Technology, Inc. and Research Triangle Institute rank within the top five despite fewer award instances, indicating larger individual contract sizes on select work. The contract portfolio has closed $16.12 billion of $22.63 billion combined potential value cumulatively since 1979, spanning 51,287 total awards. Recent activity shows a sharp decline: 1,389 awards in 2023, 1,383 in 2024, 745 in 2025, 412 in 2026, and 3 recorded year-to-date in 2027. The most recently recorded award date is in February 2027. Set-asides are minimal—89 percent of awards carry no set-aside designation, with small-business set-asides comprising 7 percent of total awards. 8(a) sole-source awards account for 1 percent, with competitive 8(a), SDVOSB, HUBZone, and WOSB each representing less than 1 percent of volume.
The EPA's grant portfolio is smaller but active, with 3,735 total awards to 498 distinct recipients since 1992, obligating $2.61 billion in federal dollars. Grant recipient concentration is highly fragmented at 10 percent top-five coverage. Rural Community Assistance Partnership Incorporated dominates recent grant activity with 23 awards and $112.6 million federal dollars obligated, followed by National Rural Water Association (12 awards, $68 million) and University Of New Mexico (8 awards, $37.6 million).
