Geophysical Survey

Applied geophysical consulting is the core service, focused on characterizing subsurface conditions through physical properties and processes. The firm acquires, processes, and interprets geophysical data in relation to real-world geology. Seismic surveys use P-wave and S-wave signals to estimate overburden thickness, depth to bedrock, seismic site class, and changes in subsurface geometry. Electrical resistivity tomography supports grounding studies, contamination flow-path mapping, and fault imaging. Utility locating uses line tracing and ground-penetrating radar to help reduce the chance of encountering unexpected utilities during excavation. Frequency-domain and time-domain electromagnetics measure subsurface conductivity to delineate landfills, contaminant plumes, voids, and other anomalies. The service area includes Washington, Oregon, Idaho, and Alaska, with the business located in Kennewick, Washington.
