ECA Geophysics was hired to perform an electric resistivity survey for a site in Colorado where we were overseeing a hydrogeological characterization study. ECA Geophysics performed the field survey in a safe and efficient manner. The data collected allowed us to better interpret the depth of the aquifer across the site, which supported refinement of the conceptual model and assisted us with locating future monitoring locations. We look forward to working with ECA Geophysics again on future projects. Leah Wolf Martin PE, PG Hydrogeologist with AJAX Ltd. Mr. Smith (ECA Geophysics) was hired by the Columbia Generating Station (nuclear facility) to provide ground (penetrating) radar (GPR) detection services for a 16-acre evaporation pond project for which I was the lead engineer. Mr. Smith worked with the project schedule that required him to use GPR to survey rolling terrain that was the 30-year old construction preparation site for the nuclear plant. Mr. Smith worked alone crisscrossing the site in over 100 F heat for over a week locating all the buried debris and electrical wiring that served the old trailers. Mr. Smith was conscientious and timely, as well as flexible when areas of concern were further investigated. The resultant location of the hidden obstructions was very helpful as the multiple pond construction project was carried out. I would not hesitate to re-hire Mr. Smith, if GPR services were again required. ECA Geophysics has done excellent work for Black & Veatch on our US Air Force range site. The geophysical data set collected in the field by ECA Geophysics was used to locate buried debris and anomalies and was considered very thorough and complete. The knowledge and ...
