Fishbeck was selected by EGLE’s Brownfield Assessment and Redevelopment Section to evaluate whether orphan sites could be redeveloped into commercial properties.
A Phase I Environmental Site Assessment (ESA) was conducted; a review of 35 years of historical environmental investigations was compiled into an updated conceptual site model (CSM), which included data tables and analytical figures. The comprehensive CSM allowed for a thorough understanding of the historical site conditions and potential for reuse. Based on the historical site conditions, the project was turned over to the EGLE-RRD Field Operations Section to conduct a comprehensive remedial investigation to facilitate an understanding of the nature and extent of impacts that extend to neighboring residential properties. Additional soil, groundwater, and vapor investigations were implemented to refine the CSM and inform additional investigative or other actions.
Based on the historical data review, the site was not considered appropriate for redevelopment due to environmental contamination. Historical records indicated that the site required vertical and horizontal delineation of soil and groundwater and evaluation of potential chlorinated volatile organic compounds in soil vapor—harmful chemicals that could affect nearby homes.
The team prepared and implemented multiple sample analysis plans, determining the need for future off-site action(s). These actions included gaining access to private residential properties to assess the subslab soil vapor conditions. Fishbeck continues to evaluate the current on- and off-site conditions in an effort to complete the conceptual site model and determine the next steps for making the site viable for redevelopment and the residential properties safe from vapor intrusion.
