Snake Valley Well Data Now Online

snake-valley-drillA new interactive map of Snake Valley with all of the well data, has recently been added to the Utah Geological Survey (UGS) Web site.  The West Desert Ground-Water Monitoring Network is almost complete and updates are available on a newly developed Google Earth™ interactive map.  The network will monitor ground water for more than 50 years in Snake Valley, western Millard County and adjacent areas.  The $3.5 million network is a response to planned ground-water development in east-central Nevada.  The Utah Geological Survey will upload data onto its Web site.

Objectives included: assessing the potential impacts of pumping on ground water and spring flow in Utah; evaluating flow patterns in the aquifer from Snake Valley to Fish Springs National Wildlife Refuge; determining baseline water-level and chemical trends in local and regional ground-water flow systems; and, measuring the capacity of the aquifers to transmit and store ground water.

OPEN-FILE REPORT 539

OFR-539MINERALOGY AND FLUID CHEMISTRY OF SURFICIAL SEDIMENTS IN THE NEWFOUNDLAND BASIN, TOOELE AND BOX ELDER COUNTIES, UTAH
Blair F. Jones, William W. White III, Kathryn M. Conko, Daniel M. Webster, and James F. Kohler

This CD contains a 53-page report (plus 43-page appendices) that details a three-year field study of Newfoundland Basin’s shallow-brine aquifer and associated playa and lacustrine sediments. Chemical and mineralogical characterization was performed on brine and selected core samples collected from the shallow-brine aquifer and sediments intercepted by 24 boreholes and 8 sets of nested monitoring wells. Aquifer tests were also conducted on specific boreholes and monitoring wells. Ground-water-brine transport in sediments of the shallow-brine aquifer occurred mainly in the permeable sedimentary facies, and possibly in vertical fissures observed in mudflat-clay facies. TEQUIL predicted mineral-sequence plots, from simulated step-wise evaporation of pore-fluid brines from peripheral and central-basin core samples, demonstrated that near-surface pore-fluid brines (<5-foot/1.5-meter depth) were a mixture of pre-West Desert Pumping Project ground water and Great Salt Lake brine. Conversely, pore fluids from core depths ranging from 5 to nearly 7 feet (1.5 to 2.1 meters) below ground level had predicted mineral sequence plots similar to the pre-pumping ground-water brine.
