About this program

The National Institute of Environmental Health Sciences (NIEHS), through its National Institutes of Health parent agency, funds basic research and training on hazardous substance detection, assessment, risk evaluation, remediation technologies, and methods to reduce the toxicity and environmental persistence of contaminants within the scope of CERCLA and SARA (93.143, CFDA), with the most recent grant award dated September 1, 2026.

The program supports research on per- and polyfluoroalkyl substances (PFAS), volatile organic compounds, heavy metals, combustion by-products, and chlorinated organics at Superfund sites and contaminated groundwater, soil, and sediment. Recent awards demonstrate focus on PFAS exposure pathways and health effects (metabolic dysfunction, hypertension, liver disease), innovative remediation technologies (microbial bioremediation, nanotechnologies, electrochemical systems, novel sorbents and membranes), detection and monitoring methods (sensors, field screening devices), and phytoremediation approaches. Awards also support training programs for occupational and environmental health professionals, international conferences on emerging contaminants, and community-engaged research in environmental justice communities.

Funding is dominated by NIEHS within NIH, which obligated $1.27 billion across 155 awards (94 percent of federal dollars). Two additional NIH components and HHS broadly account for the remainder. Over the past five years, the program averaged approximately 7.8 awards annually, with recent activity showing 7 awards in 2026 (as of September), 2 in 2025, and 11 in 2024, indicating variable but sustained activity.

The portfolio is predominantly Project Grants (93 percent of 254 awards), with smaller shares of Block Grants (5 percent) and Cooperative Agreements (3 percent). Recent awards range from $15,676 for training conference support to $22.69 million for a multi-project Superfund Research Program Center addressing volatile organic compounds and vapor intrusion. Median individual awards cluster in the $150 thousand to $4 million range for research projects.

No grant opportunities are currently open. The most active solicitation pathway forward is the Limited Competition P42 (RFA-ES-27-004), restricted to higher education institutions and due September 25, 2028, supporting five-year Superfund Research Program Centers with integrated biomedical and environmental engineering projects and supporting cores. Standard parent notices (PA-25-301 through PA-25-306) for R01 and R21 mechanisms remain available through January 7, 2028 and accept environmental health research proposals aligned with NIEHS mission, though these are not program-specific.

Objective and description

Objective

The NIEHS Superfund Basic Research and Training Program is authorized through the Superfund Amendments and Reauthorization Act (SARA) of 1986. This includes the following research and training areas directed towards understanding and attenuating the

Description

The NIEHS Hazardous Substance Basic Research and Training Program utilizes the Hazardous Substances Basic Research Grants Program (NIEHS) to support basic research and training directed towards understanding and attenuating the public health effects resulting from exposure to hazardous substances. Areas of research must be within scope of Comprehensive Environmental Response, Compensation, and Liability Act of 1980 and the Superfund Amendments and Reauthorization Act of 1986 and may include: 1) advanced techniques for detection, assessment and evaluation of the effects on human health of hazardous substances; 2) methods to assess risks to human health presented by hazardous substances; 3) methods and technologies to detect hazardous substances in the environment and 4) basic biological, chemical, and physical methods to reduce the amount and toxicity of hazardous substances. This program utilizes the P42 mechanism for broad-based, multi-disciplinary research Centers which integrate biomedical research projects with environmental science/engineering disciplines (such as engineering, hydrogeology, ecology and epidemiology). The grant can provide support for shared resources used by the Center (e.g., research support, administrative, data sharing, training opportunities). This includes support for the development of commercializable technologies through the SBIR programs.

Eligibility

Applicant eligibility

An accredited institution of higher education, as defined in the Higher Education Act, 20 U.S.C. (annotated) 3381, may submit an application and receive a grant for support of research by a named principal investigator. Subcontracts may be made with public and private organizations, including: generators of hazardous wastes; persons involved in the detection, assessment, evaluation, and treatment of hazardous substances; owners and operators of facilities at which hazardous substances are located; and State, local and Tribal governments. Nonprofit organizations which are incorporated under 501(c)(4) are prohibited from receiving grants. Organizations applying for a grant under the SBIR/STTR programs must qualify as a U.S.-owned Small Business Concern (SBC).

Beneficiary eligibility
