National Water-Quality Assessment (NAWQA) Program - High Plains Regional Groundwater (HPGW) Study

>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

  • Samples were analyzed for about 120 water-quality constituents including:
    • physical parameters
    • dissolved solids and major ions
    • nutrients and dissolved organic carbon
    • pesticides, nitrogen isotopes
    • tritium
  • The purpose of this study was to Determine the occurrence and distribution of water-quality constituents in recently recharged groundwater beneath irrigated agriculture in the central High Plains aquifer Ogallala Formation.
