About this program

The Environmental Protection Agency's Office of Research and Development has awarded six Project Grants totaling $5.9 million in federal funds under the Innovative Water Technology Grant Program (CFDA 66.521), with the most recent award issued on November 1, 2025.

The program funds development, testing, and deployment of innovative water technologies addressing drinking water supply, quality, treatment, or security challenges for public water systems, private wells, and source waters, alongside technical assistance for demonstrated technologies. Recent awards span micropollutant removal using novel adsorbents (styrene-functionalized cyclodextrin-based polymers and covalent organic frameworks for PFAS and emerging contaminants), manganese treatment optimization for small systems serving populations under 10,000, nutrient removal in lagoon wastewater systems through floating treatment wetlands and process modeling, and regulatory pathways for technology approval in very small drinking water systems. All funding is delivered as Project Grants.

Funding concentration is absolute: the EPA Office of Research and Development has issued all six awards under this program. Combined federal and non-federal dollars obligated total $9.2 million, indicating a non-federal cost-share contribution of approximately $3.3 million. Award magnitudes cluster around $1.5 million per award. Two awards issued in November 2025 targeted micropollutant removal and reached $1.54 million and $1.54 million respectively; a September 2024 award for manganese treatment demonstration was $1.54 million; a January 2023 award for lagoon nutrient removal optimization was $1.54 million; and earlier awards supported floating treatment wetland piloting ($1.58 million, November 2022) and regulatory approval frameworks for very small systems ($1.46 million, September 2021). The program has maintained a steady cadence of roughly one award per year through 2024, with two awards in 2025.

No grant opportunities are currently open. Recent competitive solicitations closed in 2024 and earlier; the most recent posted opportunity (EPA-G2024-ORD-F1, "Models to Predict the Removal of Emerging Micropollutants from Water by Novel Adsorbents in Fixed-Bed Column Processes") closed on October 2, 2024 and offered up to $1 million per award with a required 35 percent non-federal cost share. Applications must be submitted through Grants.gov and are reviewed within approximately 150–180 days of solicitation close.

Eligibility

Applicant eligibility

For certain competitive funding opportunities under this assistance listing, the Agency may limit eligibility to compete to a number or subset of eligible applicants consistent with the Agency's Assistance Agreement Competition Policy. Only these types of organizations may apply. Organization types are consistent with definitions at 2 CFR 200.1: • Public water systems located in the U.S. and its territories or possessions. Public water system, as defined by 42 U.S.C. 300f(4), means a system for the provision to the public of water for human consumption through pipes or other constructed conveyances, if such system has at least fifteen service connections or regularly serves at least twenty-five individuals. Such term includes (i) any collection, treatment, storage, and distribution facilities under control of the operator of such system and used primarily in connection with such system, and (ii) any collection or pretreatment storage facilities not under such control which are used primarily in connection with such system. Privately and publicly owned public water systems that meet the definition of a public water system in 42 U.S.C. 300f(4) are eligible to apply. • Institutions of higher education (IHEs) located in the U.S. and its territories or possessions. • Research institutions or foundations located in the U.S. and its territories or possessions. • Regional water organizations located in the U.S. and its territories or possessions. A Regional water organization, for purposes of this program, is an association or similar incorporated non-profit or governmental entity that represents or coordinates the operations of public water systems in a defined geographic area under a compact, charter or binding contractual agreement. • Certain nonprofit organizations as further described below, located in the U.S. or its territories or possessions. Note that 2 CFR § 200.1 specifically excludes Institutions of Higher Education from the definition of non-profit organization because they are separately defined in the regulation. While not considered to be a nonprofit organization(s) as defined by 2 CFR § 200.1, public or nonprofit Institutions of Higher Education are, nevertheless, eligible to submit applications under this program. As provided at 42 U.S.C. 300j-1a(a)(2)(E) and 42 U.S.C. 300j-1(e)(8)(A) eligibility is limited to ". . . nonprofit organizations that provide to small public water systems onsite technical assistance, circuit-rider technical assistance programs, multistate, regional technical assistance programs, onsite and regional training, assistance with implementing source water protection plans, and assistance with implementing monitoring plans, rules, regulations, and water security enhancements." Profit-making firms and individuals are not eligible to apply. For-profit colleges, universities, trade schools, and hospitals are ineligible. Nonprofit organizations that are not exempt from taxation under section 501 of the Internal Revenue Code must submit other forms of documentation of nonprofit status; such as certificates of incorporation as nonprofit under state or tribal law. Nonprofit organizations exempt from taxation under section 501(c)(4) of the Internal Revenue Code that lobby are not eligible for EPA funding as provided in the Lobbying Disclosure Act, 2 U.S.C. 1611. Non-domestic (non-U.S.) entities are not eligible to apply. National laboratories funded by Federal Agencies (Federally-Funded Research and Development Centers, "FFRDCs") may not apply. FFRDC employees may cooperate or collaborate with eligible applicants within the limits imposed by applicable legislation and regulations. They may participate in planning, conducting, and analyzing the research directed by the applicant, but may not direct projects on behalf of the applicant organization. An award recipient may provide funds through its assistance agreement from the EPA to an FFRDC for research personnel, supplies, equipment, and other expenses directly related to the research. Federal Agencies may not apply. Federal employees are not eligible to serve in a principal leadership role on an assistance agreement. Federal employees may not receive salaries or augment their Agency's appropriations through awards made under this program unless authorized by law to receive such funding.
