The U.S. Geological Survey is building one of the most comprehensive national views of orphan and idle wells—bringing consistency to fragmented state-level data by examining the impacts orphan wells have on groundwater and improving emission measurements in the field. This session will explore recent findings from the USGS Orphan Wells Project, including regional trends, mapping tools, and the intersection of science and remediation planning. We'll also look at how these insights can support more effective federal and state coordination.
