Opportunity Information: Apply for EPA G2022 STAR C1
This EPA Science to Achieve Results (STAR) grant opportunity focuses on building practical, defensible life-cycle and cost-benefit decision support for Enhanced Aquifer Recharge (EAR), a water management approach that stores water underground to improve supply reliability and resilience. The core aim is to help communities and water managers evaluate when and how EAR can be implemented in a way that is both cost-effective and protective of human health and the environment. Rather than funding routine implementation projects, the solicitation is oriented toward research that produces usable tools and frameworks that decision-makers can apply across different sites, hydrogeologic conditions, and recharge methods.
The solicitation lays out two main research thrusts. First, applicants are expected to identify priority research and development needs that must be addressed to support broader, safer, and more efficient EAR deployment. This can include gaps that limit confident adoption, such as uncertainties in long-term water quality outcomes, monitoring strategies, risk communication, regulatory hurdles, operational challenges, or economic tradeoffs across alternative recharge designs. The intent is to create a clear, evidence-based roadmap of where research and development efforts will deliver the most value for utilities, states, tribes, and other stakeholders considering EAR.
Second, and most central, the project must develop tools, models, and frameworks that support EAR implementation. In practice, that means producing methods that can compare costs and benefits over the full life cycle of EAR systems, not just upfront construction costs. Life-cycle style tools typically account for planning and siting, capital construction, energy and operations, monitoring and maintenance, treatment needs (if any), replacement and rehabilitation, and end-of-life or decommissioning considerations. On the benefits side, tools may address improved drought resilience, reduced surface water impacts, avoided costs from shortages, potential water quality improvements through subsurface treatment processes, and other public or ecosystem benefits. EPA is explicitly looking for research outputs that translate complex technical factors into structured decision support that can help select among design options and identify conditions under which EAR is viable, safe, and financially sensible.
Administratively, this is a discretionary EPA opportunity issued under a cooperative agreement, which usually implies more substantial federal involvement during the project compared with a standard grant. The funding opportunity number is EPA G2022 STAR C1, and it sits within the environmental funding activity category under CFDA 66.509. The award ceiling is $2,000,000, with EPA indicating it expects to make one award, suggesting a single, relatively large research effort rather than multiple smaller projects. The announcement was created on October 27, 2021, with an original closing date of January 13, 2022 (with the reminder to consult the solicitation for any details or updates on deadlines).
The solicitation also highlights human subjects research compliance requirements, which matters if the proposed research includes surveys, interviews, community studies, behavioral research, or other activities involving people. Any human subjects work funded by EPA must comply with EPA’s protections at 40 CFR Part 26. This incorporates the Common Rule requirements and includes additional restrictions and protections for pregnant women and fetuses, nursing women, and children. The announcement specifically notes that intentional exposure research, as defined in the regulation, is prohibited for pregnant women, nursing women, and children, and that observational research involving pregnant women/fetuses or children triggers additional safeguards. Every application must include a Human Subjects Research Statement (HSRS), and proposals involving human subjects research receive an additional level of review before funding decisions are finalized. The practical takeaway is that applicants need to plan early for ethics and compliance, clearly describe whether human subjects are involved, and build appropriate protections and review steps into their project design.
Overall, this opportunity is best understood as EPA funding a flagship research effort to strengthen the economic and life-cycle evidence base for Enhanced Aquifer Recharge. The expected deliverables are not just academic findings, but structured, transferable decision-support resources such as models, screening tools, or frameworks that help real-world implementers compare options, quantify tradeoffs, and move toward EAR projects that are both protective and cost-effective over the long term.Apply for EPA G2022 STAR C1
