Site Characterization

From the initial site walk, to leveraging of all available site data from diverse resources, to field studies, GSI provides the needed site characterization to support informed remedial decisions.

GSI scientists are recognized experts in the selection and application of sediment and surface water assessment tools, including specialized chemical analyses, exposure-response analysis, ecological community analysis, bioaccumulation and food web modeling, fate and transport modeling, geospatial analysis, and use of satellite or remote-based measurements. We apply these tools to empirical data to refine conceptual site models that link multiple potential sources to relevant human and ecological receptors.

FEATURED PROJECTS

Site Characterization and Benthic Community Assessment in an Estuarine Wetland

New Jersey

Conducted biological characterization and designed an approach for relating sediment chemistry, environmental parameters, and biota metrics to support a tiered remedial strategy. Also, evaluated benthic community composition using a quantitative weight-of-evidence approach to integrate sediment chemistry, toxicity bioassay results, and benthic community metrics to determine if biological impairment occurred.
