In a new report, EDGI documents the assault on the EPA currently taking place under the second Trump administration. Findings show an EPA that is swiftly being hollowed out and made to work for polluters rather than the health of the public.

contamination datasets to learn more about where PFAS have been identified, where they might be, and how source type can impact detections in environmental media.

The Landscape of PFAS Contamination in the United States: Sources and Spatial Patterns
The scope and scale of per-and polyfluoroalkyl substances (PFAS) contamination remains unknown. Using two nationwide data sets, we provide a profile of PFAS contamination in the United States and compare site categories with groundwater PFAS detections to identify site characteristics and sources of concern. We use data from the PFAS Project Lab’s Known PFAS Contamination Tracker (N = 2219) and presumptive PFAS contamination data set (N = 79,891), developed to characterize the distribution of known and likely PFAS sources. In this data set, all categories of known PFAS contamination sites are associated with average groundwater PFAS concentrations above health-based regulatory levels (4 ppt); 94% of detections exceed this limit. Aqueous film-forming foam (AFFF) use was associated with the highest average PFAS detections in this data set, and metal plating facilities account for the greatest proportion of industrial contamination sites that likely utilize PFAS (53%), though we also identified testing gaps of non-AFFF contamination sources. We conducted spatial cluster analyses, identifying hotspots of PFAS sites at national and regional levels. These findings can support multiscale approaches to PFAS remediation, including testing, siting, permitting, and community outreach, though cautious interpretation is necessary because of data set limitations. This analysis demonstrates the utility of a presumptive contamination model.
