This metadata record contains 15 tables with results from field and laboratory tests used to assess bioremediation in wetland areas at the Standard Chlorine of Delaware, Inc. Superfund site, New Castle County, Delaware, during 2019-2021. Included in the dataset are (1) polychlorinated biphenyl (PCB) concentrations in wetland sediment from sediment microcosm laboratory experiments, (2) chlorobenzene concentrations in wetland sediment from sediment microcosm laboratory experiments, (3) polychlorinated biphenyl concentrations from PCB microcosm laboratory experiments using polyethylene strips, (4) chlorobenzene concentrations from PCB microcosm laboratory experiments using polyethylene strips, (5) total iron and ferrous...
This data release contains macro and microscale datasets describing the abundance, valence states, and mineral residence(s) of chromium, iron, and manganese in natural and synthetic mineral mixtures used in laboratory experiments designed to simulate dynamic conditions in an engineered aquifer system [see Izbicki and Groover (2018) and Miller and others (2020)]. The landing page contains primary metadata about this release and an overview "sample information" table containing descriptions of samples, their analyses, and their methods of preparation and preservation. As there is not a one-to-one correlation between samples and types of analyses performed, the overview table is an important navigation tool to locate...
These data were compiled to support and inform the Bureau of Land Management’s Colorado Plateau Native Plant Program and to guide future management action when selecting regions to collect and increase seed for native plant materials development. The objective of our study was to develop geospatial datasets to aid land managers and restoration practitioners in identifying areas that will need to be restored in the future (currently disturbed) as well as areas to source new native plant materials for propagation with increased climate similarity to these areas across the Colorado Plateau, Arizona/New Mexico Mountains, and Arizona/New Mexico Plateaus. These data represent species distribution models for 12 high priority...
Mining wastes can pose environmental hazards. These hazards can be mitigated by promoting the growth of native plants that can stabilize the mine wastes and potentially toxic elements in situ (i.e., phytostabilization). We grew a widespread perennial grass species (Bouteloua curtipendula) in dolomite amended polymetallic tailings from a historic mine in southeastern Arizona (USA). We applied a compost top dressing and an endophyte seed coating alone and in combination to quantify improvements in plant growth and potentially toxic trace element stabilization. This release provides the data on the following: temperature, light, and humidity during growth; plant growth rates and biomass yields; organic matter concentrations...
