What the FY2027 request buys
Verbatim from the R-2A exhibit for project 470 of PE 0603716D8Z. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.
New projects will examine characterization and treatment of biosolids impacted with PFAS. Ongoing projects will continue to develop rapid, on-site sensors for detecting PFAS in soils and water, and further improve our understanding of the ecological toxicity of PFAS in the environment. Development will continue on advancing our ability to treat PFAS in concrete and asphalt, and further understanding PFAS-impacted microplastics in stormwater and groundwater.
The FY 2026 to FY 2027 increase of $1.955 million reflects a programmed increase for improved sensors for analysis of PFAS in the field and for improved PFAS treatment and destruction technologies.
FY2025–FY2026: what came before
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
New projects will develop rapid, on-site sensors for detecting PFAS in soils and water. Additional projects will address ecological toxicity data gaps for PFAS identified during the SERDP & ESTCP 2024 Ecotoxicity Workshop. Development continues for PFAS destruction technologies that avoid the costs of pump-and-treat methods or off-site disposal. Ongoing studies improve the understanding of PFAS transport and treatment in concrete and asphalt, advance the science of PFAS fate and transport, and develop methods for treating PFAS-impacted microplastics in stormwater and groundwater.
Development of PFAS destruction technologies, both thermal and non-thermal, will continue, with an increased emphasis on technologies for in situ destruction of PFAS and aqueous film-forming foam (AFFF) residue that avoided the expense of pump-and-treat methods. Studies of the ecological impacts of PFAS mixtures initiated in FY 2022 continued. New projects will be initiated to better understand the underlying science of PFAS fate and destruction and to detect and treat PFAS-impacted microplastics in stormwater and groundwater.
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 17.3 |
| FY2026 | Enacted | 15.9 |
| FY2027 | Request | 17.8 |
This activity is 29% of project 470's FY2027 request and 29% of PE 0603716D8Z's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
