About this program
The Environmental Protection Agency administers Surveys, Studies, Investigations, Demonstrations, and Training Grants and Cooperative Agreements under Clean Water Act Section 104(b)(3) (CFDA 66.436), with the most recent grant award dated October 1, 2025.
The program funds research, investigations, experiments, training, demonstrations, surveys, and studies addressing water pollution causes, effects, prevention, reduction, and elimination. Recent awards exemplify this scope: Rural Community Assistance Partnership received $1.375 million to provide training and technical assistance to small publicly owned wastewater treatment works and onsite/decentralized wastewater systems across all 50 states, U.S. territories, and tribal lands, focusing on operational performance, financial sustainability, disaster preparedness, and compliance. Another $3.795 million award to the same partnership network funds comprehensive training and technical assistance for private drinking water well owners and environmental health professionals, including well assessments, testing kits, webinars on emerging contaminants including PFAS, and a national help center. A $579 thousand award to the Confederated Salish and Kootenai Tribes supports monitoring, assessment, and reduction of transboundary mining pollution in the Kootenai/Y Watershed, including water quality data collection and aquatic ecosystem health documentation. Environmental education and career pathway development also receives funding: one $10 thousand award supports a six-week summer program introducing high school students to environmental careers through hands-on experience at wastewater treatment facilities.
The portfolio spans 887 awards distributed since 1994, with recent activity at 6–20 awards annually (13 awards in 2025, 6 in 2024 and 2023, 20 in 2021). Combined federal dollars obligated total $264.7 million, with an additional $25.3 million in non-federal cost-share. The Environmental Protection Agency dominates funding at $215.4 million across 772 awards; the EPA Office for Water—Funding Office contributed $32.6 million across 49 awards, and EPA regional offices account for smaller portions. The portfolio is almost entirely Project Grants (876 of 887 awards, 99%), with one Formula Grant and ten Cooperative Agreements (1%).
Award magnitudes vary widely, from $10,000 for focused educational initiatives to $3.795 million for multi-state technical assistance networks. Typical training and technical assistance awards cluster in the $1–1.4 million range; water quality monitoring and assessment projects range from $300 thousand to $600 thousand.
Recent grant opportunities remain active. EPA Region 10 posted Transboundary Watershed Grants (EPA-R10-WD-TWG-2025-01) on November 18, 2024, with a due date of January 17, 2025, targeting state, local government, and tribal entities to monitor and assess transboundary mining pollution in U.S.–British Columbia watersheds. A September 2024 opportunity (EPA-OW-OGWDW-24-04) solicited applications for training and technical assistance to small public water systems, with priority on communities of need, climate resilience, and environmental justice; that deadline closed November 25, 2024. A May 2024 opportunity (EPA-OW-OWOW-24-03) sought capacity-building training for Clean Water Act 303(d), TMDL, and nonpoint source programs; that deadline passed July 17, 2024. The program's recurring solicitation pattern—typically annual or biennial calls for training, technical assistance, and research support—indicates stable, predictable funding cycles.
