Evaluation of Paleo-climate for the Boise Area, Idaho, from the last Glacial Maximum to the Present Based on delta 2H and delta 18O Groundwater Composition
<p>There are four distinguishable groundwater systems in the Boise area, Idaho, U.S.A., identified as modern batholith, thermal batholith, Boise frontal fault, and Nampa-Caldwell systems (Figure 1). Modern batholith and thermal batholith groundwaters are located in Tertiary to Cretaceous aged …

Desalination of brackish groundwater in the United States : minimum energy requirements
… rising interest in desalinating brackish groundwater to meet fresh water demand. Various organizations in the United States have collected more hydrological and chemical data from the growing number of wells. Yet, only one national assessment of groundwater resource distribution and …

Analysis of Multi-Salt Transport and Salt Leakage Pathways in Bipolar Membrane Electrodialysis for Brine Valorization
… applying BMED to the nanofiltration permeate of groundwater that contains a high concentration of nitrate and sodium chloride. We analyze the transport of different ions in the mixed solution and compare the performance of the mixed salt permeate to an idealized single salt feed. BMED was shown …

Chlorine in ground water : stable isotope distribution
… This dissertation examined chlorine isotope composition of chloride from sea water halite, hydrothermal water samples and ground-water samples where chloride was likely moving by diffusion. The measurement method was mass spectrometry of methyl chloride gas prepared by quantitative …

Mineralogy and geochemistry of the non-sulfide Zn deposits in the Sierra Mojada district, Coahuila, Mexico
… in hemimorphite and calcite suggests that fluid composition can be related to precipitation of NSZ minerals from freshwater to slightly saline waters. Calculated salinities for two phase (liquid +vapor) and single phase (liquid) inclusions in hemimorphite range between 0.0 and 1.6 wt. % NaCl …

Geochemistry of artificial groundwater recharge into the Kopoasfontein breccia pipe near Calvinia, Karoo
Artificial groundwater recharge has been proposed as an innovative strategy for managing the scarce water supplies of the town of Calvinia, near the edge of the Karoo, South Africa. Surplus runoff water from the town dam or groundwater from boreholes in weathered shale aquifers would be injected …
