This dataset contains aqueous chemistry observations for wells, compiled by the Nevada Bureau of Mines and Geology, and published as a Web feature service for the National Geothermal Data System. Fields in the Aqueous Chemistry Observation Content Model will become XML elements in interchange documents for WMS simple features provided by a node in the USGIN network. Each feature includes an Analysis Name, label, analysis results and Source. The dataset is spatially referenced to EPSG: 4326 (for interoperability). The data contained in the submitted dataset is available as an Excel Spreadsheet, ESRI service, WMS and WFS service.
