Groundwater quality data, Platte River alluvial aquifer, near Ashland, Nebraska, 1991 to 2011

Analytical results data from 1991 to 2011 are available in tab-delimited text files below for selected explosives, field parameters, major ions, nutrients, pesticides and their degradates, stable isotopes, trace elements, volatile organic compounds, and other analytes in samples that were collected from wells screened in the Platte River alluvial aquifer, near Ashland, Nebraska. Samples were usually collected in either the spring, fall, or early winter. The sampling and laboratory analysis has been conducted by the U.S. Geological Survey.

Samples were collected primarily in six wells (M90-17R, M90-30R, M90-33R, M90-34R, M90-36R, and M91-38R) to determine the presence and, if present, concentrations of selected major ions, nutrients, pesticides and their degradates, and trace elements. These analytical results and the field parameter, stable isotope, and other analytical results data are available in this tab-delimited text file.

Samples were collected primarily in three wells (M90-1, M90-2, and M90-4) to determine the presence and, if present, concentrations of selected explosives analytes, such as cyclonite (also known as cyclotrimethylene trinitramine, Royal Demolition Explosive, or RDX) and volatile organic compounds, such as trichloroethene (also known as trichloroethylene, or TCE). The analytical results data for the selected explosive analytes are available in this tab-delimited text file; the analytical results for the selected volatile organic compounds are available in this tab-delimited text file.
