The CRMS consists of mining wastes and releases from approximately 236 abandoned gold and silver mines from three basic source areas: the proximal most location on the River starting at New Empire (Morgan Mill), Virginia City. The purpose of this dataset is to evaluate and analyze the volumes of soil, sediment, surface water and biota data collected over three decades (i.e., mid-1980s through 2015) to complete the remedial investigation (RI) at the Operable Unit (OU) No. 2 of the Carson River Site. To justify the remedy selection process to eliminate, reduce, or control risks to human health and the environment. Specifically, the RI involves the investigation and study of the spatial distribution, nature and extent of the heavy metals Mercury, Arsenic, and Lead in the Carson River drainages stemming from contaminant migration from the Carson River Mercury Site sources (i.e., Operable Unit No. 1) and evaluate past and current releases and their impact to human health and the environment. <div style='text-align:justify;'>EPA has collected soil, sediment, surface water and biota data to complete the remedial investigation (RI) at the Operable Unit (OU) No. 2 of the Carson River Mercury Superfund Site (CRMS). The goal of the study is to select a remedy that eliminates, reduces, or controls risks from site-related compounds of concern to human health and the environment.</div><div style='text-align:justify;'><br /></div><div style='text-align:justify;'>Specifically, the RI involves the investigation and study of the heavy metals contamination and the associated tributaries into the Carson River watershed resulting from site-related contaminant migration and to evaluate past and current releases and their impact to human health and the environment.</div><div style='text-align:justify;'><br /></div><div style='text-align:justify;'>The Site includes mercury-contaminated soils at former mill sites, mercury contamination in waterways adjacent to the mill sites, and mercury contamination in sediments and banks fish and wildlife over more than a 80 mile length of the River, beginning near Carson City, Nevada and extending downstream to the Lahontan Valley and ultimately at its terminus at the USFWS Stillwater National Wildlife Refuge.</div><div style='text-align:justify;'><br /></div><div><div style='text-align:justify;'>Contamination at the Site is a legacy of the Comstock mining era of the late 1860s, when mercury was imported to the area for processing of gold and silver ore. Ore mined from the Comstock Lode was transported to the mill sites, where it was crushed and mixed with mercury to amalgamate the precious metals (Washoe Process). The mills were primarily located in Virginia City, Silver City, Gold Hill, Dayton, Six Mile Canyon, Gold Canyon, and adjacent to the Carson River between New Empire and Dayton. During the mining era, an estimated 7,500 tons of mercury were discharged into the River drainage, primarily in the form of mercury-contaminated tailings.</div><div style='text-align:justify;'><br /></div><div style='text-align:justify;'><a href='https://edg.epa.gov/metadata/catalog/search/resource/details.page?uuid=%7B94BB835E-28D3-403D-8DD3-7A30021E6D9A%7D' target='_blank' rel='nofollow ugc noopener noreferrer'>Metadata</a></div></div> EPA Place Names 2015-01-31 https://ofmpub.epa.gov/sor_internet/registry/termreg/searchandretrieve/taxonomies/search.do?search=&searchString=&taxonomyName=WBT%20-%20Geographic%20Locations Web Taxonomy - Geographic Locations Nevada United States Federal Program Inventory 2013-09-16 https://www.performance.gov/federalprograminventory Federal Program Inventory 020:109 EPA GIS Keyword Thesaurus 2007-11-02 https://www.epa.gov/geospatial/epa-metadata-technical-specification EPA Metadata Technical Specification Environment My Contacts 6ffd06775caba824f39ebd1c55a29da Andrew Bain EPA Remedial Project Manager 75 Hawthorne St. San Francisco CA 94105 bain.andrew@epa.gov US 415-972-3167 True [My Contacts] Andrew Bain U.S. EPA, USFWS, USGS CRMSNVD980813646REG 09biological sampling None.
