He specializes in groundwater sampling, water-level monitoring, groundwater sample representativeness, hydraulic gradient determinations by trend-surface analyses, flow dynamics in high transmissivity aquifers, barometric corrections by multiple regression/deconvolution, analyses of automated water-level data, hydrologic testing data analysis, and statistical analyses. His experience includes implementation of remedial actions, conceptual model development, multimedia/risk assessment modeling, groundwater sample data interpretation, water level data interpretation, and reporting. He also has experience in taking hydraulic head measurements, operating continuous water-level recording equipment, generating potentiometric surface maps, conducting hydrologic tests, collecting water samples, and generating contaminant plume maps.
