Ground water recharge and flow in the regional Treasure Valley Aquifer system: geochemistry and isotope study. Research report IWRRI-2002-08 Item Info

Ground water in a regional system of deep, confined aquifers is increasingly targeted for the Treasure Valley's growing municipal and industrial water needs. Additional development of these aquifers requires greater knowledge about ground water recharge and flow in the regional system. The purpose of this study was to (1) refine the conceptual model of regional ground water recharge and flow in the Treasure Valley using hydrochemical data, and (2) provide new information for estimating regional-scale hydraulic parameters. The study objectives were to: Describe hydrochemical characteristics of principal aquifers that comprise the regional ground water flow system. Assess likely sources of recharge. Examine patterns in dissolved ion concentrations and abundance of carbon isotopes along regional ground water flow paths. Determine whether known geochemical processes describe the observed patterns. Estimate residence times for regional ground waters. Results from the study show distinctive relationships between ground water chemistry and the unique depositional environments of the principal aquifers.
