HydroResolutions Company Background
HydroResolutions, LLC was established in 2008 in Carlsbad, NM by two former Senior Members of the Technical Staff at Sandia National Laboratories, David Chace and Randall Roberts, who have both also been employed in the environmental consulting industry during their careers. We currently have offices in Carlsbad, Rio Rancho, and Socorro, NM.
HydroResolutions specializes in the characterization of the complete range of hydrogeologic systems, from the relatively simple to the extremely complex, from very high to very low permeability, from classic porous media to discretely fractured systems. We accomplish this through the application of state-of-the-art equipment and techniques. The equipment and techniques developed by HydroResolutions allow us to develop a more comprehensive understanding of hydrogeologic systems than can be gained through the application of more standard approaches.
