Geochemical Analysis of Groundwater in Eastern Ada County Completed
Groundwater is the primary source of water supply to Ada County’s growing population. Because of a proposed development near Mayfield, the Idaho Department of Water Resources (IDWR) initiated the East Ada County Hydrologic Project to improve the scientific understanding of the groundwater resources in the area.
The IDWR asked us to try to answer the following questions:
What direction is the groundwater flowing?
How old is the groundwater?
How is the aquifer recharged?
The IDWR's East Ada County Hydrologic Project is part of its Comprehensive Aquifer Management Program that “integrates hydrologic realities with social needs.”
The IDWR asked the USGS to apply its expertise in geochemical analysis to help describe the groundwater resources of eastern Ada County. We collected and analyzed water samples from Indian Creek and a small number of wells near Mayfield. We interpreted the data and published the results in a peer-reviewed report.

Recharge sources and residence times of groundwater as determined by geochemical tracers in the Mayfield Area, southwestern Idaho, 2011–12
Parties proposing residential development in the area of Mayfield, Idaho are seeking a sustainable groundwater supply. During 2011–12, the U.S. Geological Survey, in cooperation with the Idaho Department of Water Resources, used geochemical tracers in the Mayfield area to evaluate sources of aquifer recharge and differences in groundwater residence time.
