Southern California Groundwater
Langan provided litigation support services in a case regarding areas of groundwater contaminated with chlorinated solvents and degradation by-products. Our services included data review, identification of sources of chlorinated solvents, development of a chronology of events related to chemical releases, hydrostratigraphic evaluation of aquitards and vertical transport pathways, contaminant fate and transport modeling, statistical analysis of attenuation factors, and evaluation of remediation alternatives. We also provided review and plot of capture areas and changes over time, and contaminant migration relative to well capture. These data were used to evaluate likely chlorinated solvent pathways.
