Hydrogeology


The scientific study of the occurrence, distribution, and effects of ground water.

AESI has integrated geophysical investigations including seismic refraction, gravity, and resistivity surveys, with comprehensive geologic and hydrogeologic studies to properly site both test and production wells.  We have provided detailed ground water analysis and reporting for Environmental Impact Statements and water rights applications.  Our analyses have included evaluations of aquifer recharge, discharge, flow rate, hydraulic continuity, well design and capacity, and interpretation of borehole geophysical and video profiles.  Many times these types of projects entail construction-related hydrogeologic services.  AESI integrates these construction-related services, such as seepage analyses, dewatering design, infiltration system design, stability analyses, hydrologic analyses, and environmental impact assessments into current projects. 

Due to ongoing communications with the Washington State Department of Ecology, our staff has a thorough understanding of applicable laws and regulations relating to water quality, public water systems, resource protection, and other key ground water issues.  AESI strives to remain in contact with Ecology, the Washington State Department of Health, and other government agencies so that we provide our clients with the most current and accurate regulatory information possible.
