Representative Projects

Groundwater Elevation and Chemical Isopleth Development:  Developed groundwater elevation and chemical isopleth contour maps from spatial interpolation methods used as part of a US EPA- and USGS-approved 3-D numerical groundwater contamination transport model. Designed a database to catalog and track routine groundwater gauging and sampling events and generated graphs, tables, and maps representing the groundwater sampling data.  Developed a 3-D model of the geology, groundwater, and chemical plume using Earth Volumetric Studio (EVS) software.

Technical Support for Allocation of Costs Associated with Regional Contaminant Plume: Reviewed historical aerial photographs, environmental investigations, and other records dating back to the 1930s to identify pertinent site features and evaluate changes in land cover and use to develop a conceptual model of contaminant release and migration in groundwater.  Incorporated a comprehensive set of groundwater quality data into a database to develop 3-dimensional plume representations using EVS software to illustrate plume evolution over time and improve a transient numerical model.

Historical Review at a Former MGP Site:  Performed a comprehensive historical review from the 1880s through current day to guide site characterization efforts and identify other PRPs at the Site and in its vicinity.  Obtained, analyzed, and synthesized historical photographs, maps, and other images along with information and data from hydrogeologic reports and environmental investigations.  Developed a web-based GIS mapping application to help communicate the results of the analyses to key stakeholders.

Spatial Database Construction and Exploration Program Development:  Directed geospatial data acquisition, organization, and visualization.  Coordinated with multiple technical expert teams and attorneys and advised team members on GIS applications.  Researched and acquired GIS information from numerous private, state, federal, and local organizations for integration with project-specific information.  Performed spatial and temporal analyses and developed exhibits and figures for expert reports.

Data Collection and Sampling Plan Development:  Performed site visit to collect differential GPS data and photo-log pertinent features and locations.  Reviewed facility documents and developed a composite site plan showing historical sampling and exploration locations.  Developed a sampling plan using facility construction plans and field data in combination with industry standard sampling protocols to establish a randomly selected sampling location network in order to ensure spatial representativeness.
