• Technical lead and report composer for Project Managers on a various projects in both the PADEP’s Act 2 and Storage Tank Programs. Developed and implemented sampling plans, coordinated and led environmental investigations primarily of soil, groundwater, and soil vapor. • Composed various reports related to investigation and remediation projects. Reports developed ranged from small Phase II Environmental Site Assessment reports to large Remedial Investigation Reports and Site Characterization Reports at complex sites.• Performed contaminant fate-and-transport analysis of groundwater contamination at Act 2 sites utilizing Quick Domenico, SWLoad, PentoxSD, and the Toxics Management Spreadsheet, among others.• Determined aquifer characteristics from slug and pumping test data via Aqtesolv. Allowed for the determination of site’s hydraulic conductivity, transmissivity, specific storage, etc.• Utilized x-ray fluorescence (XRF) technology to delineate arsenic and chromium contamination at wood treating facilities. Additionally utilized XRF technology to guide remedial excavations of metal contaminated sites and to assess for the presence of lead-based paint during environmental investigations.• Assisted in the design and implementation of in-situ remediation projects. These included injection projects utilizing Fenton’s reagent, oxygen releasing compounds, and soy-based remedial technologies. Additionally included in-situ soil stabilization projects.

• Conducted and/or assisted senior personnel with environmental field investigations at multiple manufactured gas plant sites in Pennsylvania, New York, North Carolina, South Carolina, and Georgina and hazardous waste incineration facilities.• Oversaw and directed drilling projects involving soil sampling, groundwater monitoring well installation, lithologic logging, and environmental field screening.• Assisted with the field logging and installation of deep, water production and observation wells in Richland County, South Carolina. Also assisted with the subsequent aquifer testing and groundwater modeling using the Visual MODFLOW computer program.• Provided oversight of geotechnical investigation for remedial design at a former MGP site. The investigation included the advancement of cone penetrometer and dilatometer borings to determine the geologic integrity of subsurface sediments prior to the installation of sheet piling.• Served as hydrogeologist in support of ISCO remediation projects at two former MGP sites in South Carolina. Assisted with the ISCO design and implementation, which involved identification of impacted intervals, injector installation, overseeing injection with real time monitoring to assess appropriate injection rates, and data analyses to assess remediation effectiveness.
