Wastewater containing radiochemical and chemical constituents has been discharged since 1952 to infiltration ponds and wells at the Idaho National Engineering Laboratory. Perched ground-water zones have formed from waste-water discharged to infiltration ponds. Lithologic features controlling formation of these zones include contrasts in vertical hydraulic conductivity, baked-zone alterations, unfractured basalt, and fracture filling. Waste-disposal practices, waste volumes discharged, sorption, and radioactive decay have affected concentrations of selected constituents in perched ground water. This report presents an analysis of water-level and water-quality data collected from discontinuous perched ground-water zones during 1986--88 as part of the ongoing geohydrologic investigation at the INEL. The formation of these zones is discussed and the distribution and concentration of selected radiochemical and chemical constituents is described.
