Description: In order to collect samples which represent the levels of mercury occurring on the flood plain above Lahontan Reservoir, EPA collected surface and subsurface samples along several transects. Samples were collected along 3 transects which extended across the flood plain, perpendicular to the direction of flow. All of the transects were located below Brunswick Canyon in Dayton and Churchill Valley where the flood plain is most expansive and where there were no mills. Along each transect, 10 surface soil samples were collected and analyzed for total mercury. At the Fort Churchill gage, samples were also collected from the different stratigraphic intervals apparent in the bank of the flood plain (i.e., "FP005"). The EPA is publishing this data in support of the Carson River Mercury NPL Site in Nevada. Data was compiled and evaluated for the OU2 Remedial Investigation Report (EPA, 2017), which describes the nature and extent of contamination from the Site. The report contains the Human Health Risk Assessment and Ecological Risk Assessment Reports. Literature and other source Hg data are summarized in the RI for surface waters, sediments, and biological tissues. Metadata
