Irrigated Agricultural Land-Use Study - Ogallala Formation, central High Plains
|
Water samples from 30 randomly located monitoring wells completed in irrigated
agricultural areas overlying the Ogallala Formation of the central High Plains
area were collected. This study is part of the High Plains Regional Ground-Water
Study conducted by the U.S. Geological Survey's National Water-Quality Assessment
Program. The samples were analyzed for about 120 water-quality constituents that
included physical parameters, dissolved solids and major ions, nutrients and dissolved
organic carbon, pesticides, nitrogen isotopes, and tritium. The purpose of this
study was to Determine the occurrence and distribution of water-quality constituents
in recently recharged ground water beneath irrigated agriculture in the central
High Plains aquifer Ogallala Formation.
(see interpretive report).
