Hydrologic data in Hinkley and Water Valleys, San Bernardino County, California, 2015-2018

Data were collected to help define hydrologic controls on groundwater movement as part of a U.S. Geological Survey (USGS) study on background concentrations of hexavalent chromium in groundwater aquifers near Hinkley, California. Most data associated with the background study are available through the National Water Information System (NWIS) website, and GeoLog Locator. This product is intended to publish data that cannot be released through NWIS and GeoLog. These data include: (1) pneumatic and physical slug tests done by USGS personnel; (2) cone penetration test data collected under contract to, and reported by, Pacific Gas and Electric (PG&E); and (3) water levels in selected wells measured by consultants to PG&E and reported to the USGS.

本数据集为美国地质调查局（U.S. Geological Survey, USGS）相关研究的配套数据，该研究针对加利福尼亚州辛克利（Hinkley）附近地下含水层中的六价铬（hexavalent chromium）背景浓度展开，旨在明确地下水运动的水文控制机制。该项背景浓度研究的绝大多数数据可通过美国国家水信息系统（National Water Information System, NWIS）官网及GeoLog Locator平台获取。本数据集旨在发布无法通过NWIS与GeoLog平台公开的数据，具体包含以下三类：1. 美国地质调查局人员开展的气压式与物理式段塞试验数据；2. 由太平洋天然气和电力公司（Pacific Gas and Electric, PG&E）签约采集并提交的圆锥触探试验数据；3. 由太平洋天然气和电力公司咨询团队测量并上报至美国地质调查局的选定监测井水位数据。
