Offering Sound Scientific Solutions To Water Resource Issues
Roux works with non-profit, public, and private sector clients in the analysis, management, and wise development of their water resources. Because of the complexities involved in managing water resources, those responsible for solving water supply issues and evaluating overall water needs require proven expertise. Roux combines field investigations, laboratory analyses including geochemical isotope analyses, and advanced two- and three-dimensional modeling techniques to conduct our investigations, analyses, and plan development.
Our experience includes evaluating site, watershed, and regional aquifer systems spanning multiple states. Roux routinely evaluates conditions related to groundwater-dependent ecosystems, including groundwater, surface water, and wetlands sampling and characterization; watershed assessments; spring source investigations; determining connectivity between aquifers; design and construction of production wells; and aquifer pumping evaluations.

“Andy’s expertise in desert hydrology is unparalleled. His extensive work mapping springs in the Mojave Desert has been a great resource for several conservation clients I work closely with. His firm has also handled environmental assessments (Phase Is) and soil borings and water samples (Phase IIs), which enabled several properties that would otherwise not have been eligible for conservation to be restored and preserved. With his warm nature and quick wit, I can assure you that you’ll enjoy working with Andy.”

"Andy was involved in the design and management of several projects for the company. We have engaged Andy on complex groundwater modeling and analysis as it relates to our watersheds here at the ski area, and the development of water resources therein for snowmaking and domestic water supply. I whole-heartedly endorse and recommend Andy Zdon to perform in the role of a professionally registered hydrogeologist."

Vice President, Planning, Mammoth Mountain Ski Area, LLC
"For many years, I have worked with Andy on the County of Inyo's challenge to the proposed Yucca Mountain Nuclear Waste Repository. Andy has always promptly completed work within budget that involved evaluating and reporting on the hydrology of the Amargosa River Basin with a focus on whether the proposed repository will potentially result in contamination of the basin's groundwater. His work and reports are excellent. Moreover, Andy is warm and friendly and is a pleasure to work with."
