Christopher Gale is a Principal Geologist based in California with more than 15 years of environmental experience focusing on complex site characterizations, feasibility studies, remediation system conceptual design, remedial system optimization, vapor intrusion evaluation, and regulatory compliance.
Among Chris’ key strengths is assisting his clients with the investigation and remediation of complex contaminated site involving groundwater and soil vapor impacts. He has experience designing and implementing remedies utilizing a wide variety of remedial alternatives including bioaugmentation, zero-valent iron (ZVI) amendments, electrical resistance heating (ERH), soil vapor extraction (SVE), dual phase extraction (DPE), and in-situ chemical oxidation (ISCO). Chris successfully managed the remediation of a mixed LNAPL/DNAPL site using combined remedies which resulted in the removal of over 21,000 lbs of VOC mass, the reduction of dissolved groundwater concentrations to below risk-based thresholds, and regulatory approval of the completion of remedial actions in less than 4 years. He has successfully assisted clients in identifying and understanding false positives in vapor intrusion evaluations and avoiding the need to install unnecessary vapor intrusion mitigation systems.
Chris advances the state of the practice through the implementation of combined remedies approaches to achieve project success at complicated sites and the use of Geosyntec’s advanced vapor intrusion assessment methods and tools to assist clients in efficiently and effectively evaluating potential vapor intrusion concerns at their sites. Chris has presented on combined remedies strategies and novel vapor intrusion evaluation methods at multiple national and international conferences.
