U.S. Geological Survey, Lower Mississippi-Gulf Water Science Center 20201215 vector and raster digital data https://doi.org/10.5066/F74M93FJ Roland W. Tollett 2022 publication n/a US Geological Survey https://doi.org/10.3133/sir20215101 In 2015-2016, physicochemical properties and chemical characteristics of stream water, bed sediment, groundwater, and soil were determined in watersheds located outside of, but in proximity to, the Peason Ridge Training Area and Main Post at the Joint Readiness Training Center and Fort Polk boundaries to document background trace element concentrations. Water samples were analyzed for physicochemical properties, major inorganic ions, selected trace elements, and dissolved organic carbon. Selected trace elements included antimony, arsenic, cadmium, copper, iron, lead, manganese, mercury, and zinc. Stream bed-sediment and soil samples were analyzed for major inorganic ions, selected trace elements, and grain size distribution. Surface-water samples were collected near the downstream transect of each stream reach. Monitoring wells were located adjacent to the stream reach and in close proximity to the surface-water sampling sites. Bulk bed-sediment samples were collected during normal low-flow conditions. Each sample consisted of a composite sample from five locations (right edge, left edge, and center of a middle transect, then upstream and downstream of the middle transect) within each stream reach. Three soil samples, one from hilltops, one from side slopes, and one from riparian zones, were collected from areas adjacent to each stream reach. Each soil sample consisted of 5 to 10 grab samples collected by a 21-inch-long, 5/8-inch internal diameter stainless-steel hand auger and composited in Teflon lined pans. All samples were collected following USGS sampling protocols. This data release provides database and mapping information for assessment of trace element concentrations in stream water, bed sediment, groundwater, and soil found in relatively pristine and undisturbed watersheds in proximity to watersheds used for military training. This data set provides the geographical background of the Little Kitsatchie Bayou study area. The zip folder called "little_kisatchie" includes all of the shapefiles required to produce a complete image in ArcGIS of the study area, including the location of two specific sites that were sampled for the study. Inside this folder, the shapefiles are separated into two folders called "site1_kisatchie" and "site2_kisatchie." 20151201 20160831 ground condition Complete None planned -93.168403585 -93.121494448 31.395092732 31.36130262 Marine Realms Information Bank (MRIB) keywords sediment analysis USGS Thesaurus groundwater and surface-water interaction surface water quality USGS Metadata Identifier USGS:5ab926b4e4b081f61ab9c8a3 Common geographic areas Kisatchie None.
