Overview of fractured rock research aimed at understanding the movement of water through fracture networks, and characterize field conditions influencing contaminant migration. Includes programs and publications.
Recent increases in dissolved-solids concentrations in this aquifer have been documented in some areas used for public supply, raising concerns as to the sources and causes of the higher concentrations and the long-term effects on groundwater quality.
National Water Information System (NWIS) real-time data on selected ground water sites, ground water level data, site inventory of wells, test holes, drains, springs and excavations and ground water-quality data for the United States.
Sampling program to determine if pesticides are present in ground water, in accordance with Wyoming's Generic State Management Plan for Pesticides in Ground Water (SMP).
Arsenic was the trace element most frequently present at high concentrations here. High concentrations of arsenic result from the interaction of groundwater with naturally occurring minerals.
Arsenic and nitrate are the constituents found most commonly at high concentrations in the primary aquifers. Arsenic comes from natural sources and is affected by pH and dissolved oxygen.
