        <idPurp>This feature class contains data collected by EPA of wildlife prey and their tissues analyzed for mercury to assess exposure at the site. EPA collected benthic invertebrates (caddisfly larvae and crayfish) from four locations on the Carson River between 1994 and 1995.</idPurp>
        <idAbs>&lt;div style='text-align:justify;'&gt;For the Ecological Risk Assessment Report, EPA collected these samples, consisting of benthic invertebrates (crayfish), from three contaminated locations in the Carson River upstream from Lahontan Reservoir (Santiago Ruins, Dayton State Park, and Fort Churchill) and one background location (Ruhenstroth Dam).&lt;/div&gt;&lt;div style='text-align:justify;'&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style='text-align:justify;'&gt;As a component of the ecological assessment for the Carson River Mercury Site, a survey of benthic macroinvertebrates was conducted to evaluate the potential adverse effects of mercury in surface water and sediment of the Carson River. Measures of benthic community response to mercury contamination derived from the benthic survey are presented in this the EcoRisk Assessment, Appendix C. A characterization of the existing environment at the sampling locations-including the habitat characteristics, fish and wildlife populations, and surrounding land use.

Rapid BioAssessment Protocol II (RBP) involves the standardized collection, enumeration, and identification of major benthic taxa to the family level in riffle/run habitats.&lt;/div&gt;&lt;div style='text-align:justify;'&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style='text-align:justify;'&gt;Standard data sheets are used to record results at each sampling. location. Collections are compared to a reference location, and an evaluation is made as to the impairment, or lack thereof, of the benthic community from stressors within the watershed. The biological condition of the community can be ranked according to three categories of impact: nonimpaired, moderately impaired, or severely impaired, where the degree of impairment implies less than optimal community structure, the loss of intolerant species, and dominance by a few tolerant taxa compared to background.&lt;/div&gt;&lt;div style='text-align:justify;'&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style='text-align:justify;'&gt;RBP II also involves assessment of habitat characteristics such as stream flow, bottom conditions, and riparian vegetation. In addition, standard water quality parameters such as dissolved oxygen, temperature, pH, conductivity, color, and turbidity are determined.

The RBP II was conducted on August 17 and 18, 1994 during a period of drought. The EPA is publishing this data in support of the Carson River Mercury NPL Site in Nevada.  Data was compiled and evaluated for the OU1 Remedial Investigation Report (EPA, 1994) as well as the OU2 Remedial Investigation Report (EPA, 2017), describing the nature and extent of contamination from the Site, primarily the Ecological Risk Assessment Report.  The RI report also contains the Human Health Risk Assessment.&lt;/div&gt;&lt;div style='text-align:justify;'&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style='text-align:justify;'&gt;Literature and other source Hg data are summarized in the RI for surface waters, sediments, and biological tissues.&lt;/div&gt;&lt;div style='text-align:justify;'&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style='text-align:justify;'&gt;&lt;a href='https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B2AF6806E-189F-454A-A792-9EF6A2BF240E%7D' target='_blank' rel='nofollow ugc noopener noreferrer'&gt;Metadata&lt;/a&gt;&lt;/div&gt;</idAbs>
