Christopher S. Johnson, PG, CHg, has nearly 40 years of applied industry experience in groundwater assessment, hydrogeology, well design and construction, well rehabilitation, groundwater aquifer testing, geochemistry, and hard rock aquifer assessments.
Key project experience ranges from deep water supply wells designed to avoid naturally occurring contaminants and project manager for groundwater monitoring at the Hunters Point Naval Shipyard in San Francisco to the technical lead on the Deep Groundwater Monitoring Well Installation Program for the Los Alamos Nuclear Laboratory in New Mexico. Johnson has assessed aquifers for the source of naturally occurring arsenic and uranium, then successfully designed high-capacity municipal supply wells with little to no reportable concentrations of these constituents present. He has been the principal hydrogeologist on several large-scale groundwater assessments that included modeling and testing aquifer performance of deep, high-capacity test wells.
Knowledgeable of both technical and regulatory requirements, Johnson has significant experience in conducting cost-benefit analysis for new wells, new wellfields, well rehabilitation, and aquifer assessments. He is also well versed in dealing with regulatory requirements related to water quality, production, and basin yield.
