Brendan Merk is a professional geologist with over twenty years of experience performing property assessments, subsurface investigations, environmental evaluations, and managing remediation efforts. He applies his expertise to forensic casework investigating the cause and cleanup of soil and groundwater contamination, concerns regarding petroleum and hazardous chemicals, the determination of groundwater flow and contaminant transport, and other geologic hazards.
With a focus on hydrogeology in his undergraduate and graduate education, much of Brendan's professional experience involves groundwater modeling. He has a strong background in the removal and assessment of Underground Storage Tank (UST) facilities, Phase I and Phase II Environmental Site Assessments (ESA), and performing asbestos surveys for properties undergoing demolition. Brendan is also proficient with field sampling techniques such as soil sampling, monitoring well installation, low-flow groundwater sampling, soil vapor sample collection, and free-product recovery from groundwater.
Brendan has implemented environmental corrective actions with technologies including dig and haul, soil and groundwater vapor extraction, carbon and bioremediation injections, property restrictions, and contaminant modeling. Bedrock investigations have included assessments in karst areas as well as coring and pressure testing in competent rock.
Brendan is a licensed Professional Geologist in Kentucky and Indiana and a certified Asbestos Inspector in Indiana. He has a B.S. degree in Geology from Ball State University and a M.S. degree in Geology from the University of Cincinnati.
A Professional Geologist with experience in the environmental field since 1997, proficient with property assessments, subsurface investigations of soil, groundwater, air, and the remediation of petroleum and hazardous chemicals. Performed asbestos surveys, including the sampling of building materials for the laboratory determination of asbestos content. The results of such surveys have been used to complete the requirements for pre-demolition assessments.
Strong background in the removal and assessment of Underground Storage Tank (UST) facilities, Phase I and Phase II Environmental Site Assessment (ESA) investigations, per industry standards. Proficient with field sampling techniques such as soil investigation, monitoring well installation, low-flow groundwater sampling, soil vapor sample collection, and the recovery of free-phase hydrocarbons from groundwater. As well as the assessment of surface water and groundwater flow regarding soil competence.
Implemented environmental corrective actions with technologies including dig and haul, soil and groundwater vapor extraction, carbon and bioremediation injections, property restrictions, and contaminant modeling. Bedrock investigations have included assessments in karst areas, as well as coring and pressure testing in competent rock. With a focus on hydrogeology in undergraduate and graduate education, his professional experience includes the modeling of groundwater for a variety of geologic settings in Ohio, Georgia, and Florida.
