GeoSystems Analysis, Inc. services

GSA has extensive experience related to groundwater resources and managed aquifer recharge having conducted over 30 groundwater recharge projects in the western United States, with a total recharge capacity exceeding 500,000 acre-feet per annum. GSA also specializes in the design and installation of innovative vadose zone and groundwater characterization systems that have been used to monitor irrigation efficiency and groundwater and soil salinity. In addition, we have published numerous manuscripts on groundwater recharge processes and instructed short courses on siting groundwater recharge projects. GSA also provides technical services to evaluate groundwater resources, surface water-groundwater interactions, and the effect of urbanization on natural groundwater recharge rates.

At GeoSystems Analysis, Inc. (GSA), one of our core strengths is in the field of vegetation ecology. Clients seek our expertise with designing and implementing vegetation-monitoring programs, performing botanical surveys and inventories, mapping vegetation communities and developing vegetation management plans. We also routinely perform applied research for clients interested in understanding plant-soil-water interactions to advance their land reclamation and habitat restoration programs.

GeoSystems Analysis, Inc. provides a full range of habitat restoration support services. Clients seek our expertise to enhance restoration success and promote long-term resilience by integrating soil science, vegetation ecology, and hydrology into restoration programs. We characterize site conditions, develop restoration plans, write grants and develop project funding strategies, manage and oversee project implementation, and perform effectiveness and validation monitoring to support both programmatic and project level adaptive management planning. We also implement applied research projects to advance the practice of ecological restoration.

GSA has extensive experience in characterizing and monitoring solution and air-flow to optimize heap leach design and operations. Our successes include installing some of the first large-scale heap-leach monitoring systems in North and South America, groundbreaking research on flow in gravelly materials, and the development of integrated laboratory, field and modeling methods to evaluate heap leach fluid dynamics and metal recovery. GSA is also unique in that we operate an unsaturated flow laboratory that specializes in characterizing mine waste and heap leach material. We have conducted extensive research and developed advanced laboratory methods to predict solution behavior and air flow in heap leach environments.

GSA has conducted mine reclamation closure studies at over twenty sites ranging from the Great Basin and Southwestern deserts in the United States to the Andean mountains of South America to tropical Papua New Guinea. GSA utilizes an interdisciplinary approach to mine reclamation projects through our expertise in ecological restoration, reclamation cover systems, and groundwater hydrology. GSA is also unique in that we operate an unsaturated flow laboratory that specializes in characterizing mine waste, heap leach, and cover system materials. We have developed advanced laboratory, field and modeling methods to predict unsaturated flow behavior in these rocky materials and apply this expertise to determining flow in heap leach materials, the effect of sloping cover systems, and changes in cover system hydraulic properties over time.

GSA has earned a leading reputation in designing and implementing monitoring systems and developing research programs to evaluate hydrologic and ecological processes. GSA has deployed and maintained instrumentation for long-term monitoring of climate, vadose zone flow and transport, surface water flow and quality, and groundwater elevation and quality. GSA’s monitoring systems are designed to withstand environmental conditions while meeting data requirements. Because of the harsh environments and uniqueness of GSA projects, we have developed proprietary sensors to meet specific project needs. GSA is also unique in that we operate a hydrologic testing laboratory that uses state-of-the-art methods to determine saturated/unsaturated flow properties of porous media. The laboratory specializes in determining the flow properties of soils and waste material with significant amounts of gravel fragments under various conditions of saturation and load pressure.
