Table 8. Geochemical modeling results for interbasin flow, Basin and Range carbonate-rock aquifer system study area, Nevada and Utah.
[Flow path No. matches corresponding number in figure 45. Boundary or divide: HA, hydrographic area; IB, intrabasin. Geochemical model, mixtures of initial and recharge waters, represents total mixture of initial and recharge waters for first (upper mixture) and second (lower mixture) model evaluations. Initial water, first point along selected ground-water flow path. Recharge water contributed from surrounding recharge areas]
