Developing or refining a conceptual site model depends on integrating multiple sources of historical information, collecting quality data, and incorporating the data into a database that is used to further refine delineation. Visualizing subsurface conditions allows GZA to develop realistic investigation plans to locate and quantify impacted media. Our experience with investigation techniques, computer modelling, and data management makes efficient use of site investigation time and expenses. GZA’s technical capabilities are enhanced by our management skills in coordinating and obtaining the necessary permits, site access agreements, and subcontractors.
