A challenging Brownfields redevelopment project that includes addressing organochlorine pesticide (OCP) impacts was the subject of a presentation by team of Geosyntec and CSX Transportation, Inc. (CSXT) professionals at the annual
Florida Brownfields Conference
, held Nov. 15-16 2011 in Orlando, Florida.
Geologists Aaron Getchell, Teresa Fischer, and Michael Lodato prepared a case study in poster form, "New Hope for the Old Hopewell Road Brownfields Site," at the event. The team collaborated on the poster with Raghu Chatrathi, a CSXT remediation manager.
The poster presented the project background, where a chemical company produced, stored, and distributed OCPs between 1967 and 1972 at the Tampa property. A decade later, CSXT assumed environmental liability for property adjacent to the property. In 2002, CSXT entered into a
Brownfields Site Rehabilitation Agreement
(BSRA) with the Florida Department of Environmental Protection (FDEP) to remediate the property for redevelopment and future use.
The project presented several challenges to the Geosyntec team when they began work in 2006, including: the coordination of assessment and remediation activities at the site with an adjacent property owner. The team also had to characterize the site based on a large historic dataset assembled from multiple sources, some dating back more than a decade.
Geosyntec recently submitted its remedial action plan for the site to the FDEP Southwest District. Proposed remedial actions include installation of a vertical barrier wall to isolate OCP impacted soil from the adjoining property; excavation of OCP impacted soils to minimize the potential for contaminants to leach into groundwater; and monitored natural attenuation for existing impacted groundwater.
Principal Engineer Nandra Weeks, PE, and Graphic Designer Pam Wood also collaborated on the presentation for the conference. For more information about the project site, contact Aaron Getchell, 813-558-0990 or
