New Test Measures Brine Release Capacity of Geologic Material

DBS&A, in conjunction with the University of New Mexico’s Department of Civil Engineering, developed a method to estimate the brine released by pumping a brine-saturated geologic unit. This method addresses the need of people who are evaluating mineral-rich brine-saturated deposits for a rapid screening test—one that is suitable for multiple samples and textures and that avoids issues associated with brine as the pore fluid.  The test method involves applying a vacuum to a group of saturated samples in a parallel configuration (as shown in the figure). The parallel configuration allows rapid analysis...

Geochemistry: How It Can Help You

Geochemistry applies chemical principles to hydrologic and geologic problems and water quality evaluations. DBS&A’s geochemistry experience ranges from examination of natural conditions in groundwater and surface water to inorganic and organic contamination issues. Our geochemists have the capability to assist our clients with projects ranging from comparing water quality with state, federal or tribal standards to computer modeling of complex geochemical systems at superfund, industrial, landfill, or mine sites.

Minimizing Risks of Geologic Carbon Dioxide (CO₂) Sequestration

DBS&A experts provided key technical expertise to the U.S. Environmental Protection Agency in developing final Underground Injection Control (UIC) rules for permitting carbon dioxide injection wells associated with geologic sequestration. DBS&A can apply this expertise—and our experience with multi-phase fluid modeling, vadose-zone and groundwater monitoring programs, and subsurface injection—to support your developments in geologic sequestration while protecting groundwater resources. Proper siting, operation, and monitoring can minimize risks associated with CO₂ sequestration.
