Spatial Patterns and Temporal Variability in Water Quality from City of Albuquerque Drinking-Water Supply Wells and Piezometer Nests, with Implications for the Ground-Water Flow System

摘要

This report examines water-quality data for City drinking-water supply wells and deep piezometer nests to improve understanding of the regional geohydrologic framework. Water-level data for the deep piezometer nests were also examined to better define the ground-water flow system and its response to ground-water pumpage. Examination of water-quality data is limited to a subset of 10 water-quality parameters (dissolved solids, calcium, sodium, bicarbonate, sulfate, chloride, silica, arsenic, field pH, and water temperature) selected to represent major-element and trace-element chemistry and physical properties of water from the aquifer. These 10 water-quality parameters are examined for spatial patterns, both areally and with depth, and implications for ground-water source areas and flow paths.
