Ms. Perrigo provides ground work for Pinnacle GeoSciences' environmental assessment and analysis by researching historical geography, property ownership, land uses and activities, as well as historical commercial and industrial practices.  This has involved developing a significant in-house research library of local historical publications, maps, photographs, and anecdotal information as well as a large compendium of on-line and public sources to research historical property characteristics and potential environmental issues.
