USGS scientists conduct research and provide technical expertise, at the request of the NRDAR program, to determine the extent to which natural resources have been impaired as the result of hazardous substance releases and support restoration activities for the recovery of those resources.
To learn more about how USGS science can support the NRDAR program contact Jo Ellen Hinck, the USGS NRDAR Coordinator or reach out to the individuals below to learn more about their NRDAR experience and expertise.
