This data set contains imagery from the National Agriculture Imagery Program (NAIP). The NAIP program is administered by USDA FSA and has been established to support two main FSA strategic goals centered on agricultural production. These are, increase stewardship of America's natural resources while enhancing the environment, and to ensure commodities are procured and distributed effectively and efficiently to increase food security. The NAIP program supports these goals by acquiring and providing ortho imagery that has been collected during the agricultural growing season in the U.S. The NAIP ortho imagery is tailored to meet FSA requirements and is a fundamental tool used to support FSA farm and conservation programs....

Samples were submitted for contract laboratory analysis as part of a study examining the occurrence of chromium and natural and anthropogenic hexavalent Chromium, Cr(VI) in groundwater. Data will be used to estimate naturally-occurring background Cr(VI) concentrations upgradient, near the plume margins, and downgradient from a mapped Cr(VI) contamination plume near Hinkley, CA (Izbicki and Groover, 2016). These Contract Lab results are part of the data release including grain-size distribution, photographic and associated chemical and mineral analysis data for 36 sediment core and alluvium samples as well as Scanning Electron Microscopy analysis on select grains from magnetic and heavy mineral separates collected...

These data were collected using field portable (handheld) X-ray fluorescence (pXRF) equipped with a 4-watt Ta/Au X-ray tube. Samples of surficial alluvium, rock, and archived core material from existing auger- or sonic-drilled monitoring wells in Hinkley Valley and the adjoining Water Valley, 140 kilometers (km) northeast of Los Angeles, California, were measured as part of an investigation of naturally-occurring and anthropogenic hexavalent chromium, Cr(VI), concentrations in local groundwater. Surficial alluvium samples were collected from small stream channels draining distinct geologic units, or from previously mapped river deposits, and generally consisted of silt, sand, and granules to small pebbles. Twigs...

These data on the concentrations of 27 selected elements were collected using a field portable (handheld) X-ray fluorescence (pXRF) instrument (Groover and Izbicki, 2016) equipped with a 4-watt Ta/Au X-ray tube on samples of 1) surficial alluvium, 2) rock, and 3) archived core material and drill cuttings from monitoring wells across an approximately 14,300 square kilometer area in the western part of the Mojave Desert, between 60 to 210 kilometers (km) northeast of Los Angeles, California. These samples were measured using a pXRF as part of a regional-scale investigation of naturally-occurring trace elements (including arsenic, chromium, and uranium) dissolved in groundwater (Groover and Izbicki, 2018), and a local-scale...

Grain size analysis using an Advantech Sonic Sifter Separator was conducted as part of a study examining the occurrence of chromium and natural and anthropogenic hexavalent Chromium, Cr(VI) in groundwater. Data will be used to estimate naturally-occurring background Cr(VI) concentrations upgradient, near the plume margins, and downgradient from a mapped Cr(VI) contamination plume near Hinkley, CA (Izbicki and Groover, 2016). Following field collection the samples were sieved into the greater than and less than 2 millimeter size fractions. The less than 2 millimeter fraction was sifted into seven grain size ranges. Each size fraction was weighed to 0.1 grams and photo documented. The cooperator for this study is...

Scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) were used to analyze acid residues from heavy mineral separates, polished grain mounts, and clays from sampled sediments as part of a study examining the occurrence of chromium and natural and anthropogenic hexavalent Chromium, Cr(VI) in groundwater. Data will be used to estimate naturally-occurring background Cr(VI) concentrations upgradient, near the plume margins, and downgradient from a mapped Cr(VI) contamination plume near Hinkley, CA (Izbicki and Groover, 2016). Results from EDS and SEM are presented as PDF reports and TIFF images. These data are part of a data release including grain size distribution, photographic and associated...

Cone penetration data reported by Pacific Gas and Electric Company are reported here in support of a U.S. Geological Survey background study on hexavalent chromium concentrations in Hinkley Valley, California. Cone penetration tests are a minimally invasive direct push method of measuring subsurface properties, primarily related to soil friction and resistance to penetration. These data can be interpreted to provide information on soil types and behaviors.
