Technical and Administrative Support to the U. S. Environmental Protection Agency

The Technical and Administrative Support to the U.S. Environmental Protection Agency (EPA) is a multiple-award Indefinite Delivery/Indefinite Quantity (IDIQ) contract vehicle designed to provide comprehensive technical and administrative support to the EPA's Office of Water (OW) and its various subdepartments. The contract, valued at $16.7 million, supports critical water-related functions across multiple program areas, including groundwater and drinking water, science and technology, wetlands, oceans, watersheds, and wastewater management. Based on the original solicitation, the contract encompasses a wide range of services such as cross-cutting technical activities, data collection and analysis, writing and editing, peer review, water quality modeling, program management, strategic planning, outreach, communications, and quality assurance support.

The task orders under this contract are predominantly cost-plus-fixed-fee delivery orders, typically ranging from approximately $50,000 to $3.7 million, with performance periods often spanning one to three years. Two prime contractors, Avanti Corporation (a Native American woman-owned small business) and Horsley Witten Group, Inc., have been the primary awardees, consistently winning task orders focused on technical support for water-related initiatives. Common project scopes include lead service line inventories, water quality standards academy support, strategic foresight assessments for climate-ready estuaries, technical support for regulatory processes, and national aquatic resource surveys. While the contract was originally set aside for small businesses, the recent task orders have not maintained a specific set-aside designation. The work is predominantly performed in locations such as Alexandria, Virginia, Sandwich, Massachusetts, and supports EPA offices nationwide, with a strong focus on environmental consulting, regulatory development, and scientific support services.
