Reconnaissance of Ground-Water Quality in the Papio-Missouri River NaturalResources District, Eastern Nebraska, July through September 1992

摘要

The purpose of this report is to describe the water quality of the principalaquifers in the study area. Wells representative of the geology and land use in the study area were selected for water-quality sampling. Variations in constituent concentration among aquifers are discussed. The report describes the spatial distributions of dissolved nitrite plus-nitrate as nitrogen and triazine and other acetanilide herbicides and evaluates the effects of cropland application of nitrogen and herbicides on the ground-water quality within the study area. The report also summarizes the concentrations of dissolved major and trace constituents including radionuclide activity and concentration.
