Compilation of selected data for thermal-water wells and springs in Idaho, 1921 through 1991

Abstract

Selected well-inventory and water-chemistry data for 718 thermal-water wells and springs in Idaho were compiled. A total of 1,319 chemical analyses are presented. Analyses were performed at U.S. Geological Survey laboratories from 1921 through 1991. Most data are for sites in southwest and south-central parts of the State.

Recharge sources and residence times of groundwater as determined by geochemical tracers in the Mayfield Area, southwestern Idaho, 2011–12

“…Samples from the perched aquifers tended to be more enriched (less negative ratios) than water from the deep aquifer. All samples collected during this study were more enriched than a data point representing mean geothermal water in Idaho, but still are within the range of stable isotopes exhibited by geothermal water (Parliman and Young, 1992). All water samples plot below the GMWL and LMWLs, but they still fall in a linear pattern, likely indicating that the study area may have its own meteoric water line different from the GMWL and the LMWLs.…”

“…The stable isotope ratios in water samples (table 7) were plotted on a delta diagram ( fig. 6) with the GMWL and the two LMWLs, as well as the mean stable isotope values from geothermal waters in Idaho (Parliman and Young, 1992). The most negative (depleted) ratio was from the Indian Creek sample collected during winter.…”

“…The main focus of this work was to identify the chemical reactions between the aquifer matrix and groundwater that control solute concentrations in the SRP aquifer system. Parliman and Young (1992) described selected well-inventory and water-chemistry data for 718 thermal-water wells and springs in Idaho, including four near the Mayfield area. Analyses included major ions, nutrients, bacteria, trace elements, and oxygen/deuterium.…”

“…A ternary diagram ( fig. 9) with exaggerated lithium and boron concentrations was constructed to plot thermal waters from the Idaho Batholith (Berkeley Group, Inc., 1990;Parliman and Young, 1992;Druschel and Rosenberg, 2000) and water samples from the study area. Five samples collected from the deep aquifer plot close to thermal waters from the Idaho Batholith, suggesting geothermal water similar to that of the Idaho Batholith may recharge the deep aquifer.…”

Distribution of Isotopic and Environmental Tracers in Groundwater, Northern Ada County, Southwestern Idaho

“…Groundwater was determined to be a calcium-sodium-bicarbonate type, and concentrations of iron (exceeding 0.3 mg/L) and fluoride (as high as 13 mg/L) were high in select samples. Parliman and Young (1992) described selected wellinventory and water-chemistry data for 718 thermal water wells and springs in Idaho, with about 12 of these in northern Ada County. Analyses included major ions, nutrients, bacteria, trace elements, tritium, oxygen/deuterium, radiocarbon, and sulfur isotopes (δ 34 S).…”
