Hydrogeologic Services
Since its inception, Robinson, Noble & Saltbush has excelled in conducting hydrogeologic studies that investigate regional areas within water district boundaries, river drainage basins, or multi-county aquifers. These investigations typically require the collection and analysis of large amounts of hydrogeologic information, including: well logs, water right allocations, geologic maps, precipitation records, groundwater levels, stream flows, and water use. Analysis of this information results in the preparation of hydrogeologic cross sections and water table maps, definition of aquifer system boundaries and characteristics, and conceptualization of groundwater flow systems.
Robinson, Noble & Saltbush has been studying the stratigraphy of the Pacific Northwest for more than 50 years. This experience provides our hydrogeologists a large advantage in delineating aquifers from existing data sources, such as drillers’ well logs. Providing clients with hydrostratigraphic analyses, defining aquifers and non water-bearing zones, is a routine service accomplished for water resource studies, landfill/contamination studies, hydrogeologic assessments, and other projects.
Aggregate Services
Given the increasing restrictions being placed on the location of mines in proximity to ground water and within floodplain environments, a hydrogeologic study is increasingly necessary beyond just estimating the mineable material or the location of washwater sources. A regional hydrogeologic study will guide the development and implementation of reclamation plans and, perhaps most importantly, provide the information necessary to appropriately constrain the potential impacts (or lack thereof) to be addressed during the permitting process.
