Environmental Expert Recounts Implications of Groundbreaking Cleanup of Columbus Site

COLUMBUS, Ga.. — Georgia Power’s environmental affairs manager Darahyl Dennis will discuss how cleanup of a Columbus site revolutionized environmental policymaking regarding ground contamination in a presentation, “Toxic Rock: What is it? Why it is Important,” at 6:30 p.m. Thursday, Oct. 14 in the Studio Theatre at Theatre on the Park on Columbus State University’s RiverPark campus.

Admission is free and open to the public.

Dennis, a 1974 Columbus State biology graduate, will describe how, in 1992, a method referred to as in-situ solidification was used in cleaning up the site of the former Columbus Manufactured Gas Plant, and how this pioneering method has subsequently and effectively been applied around the world.

Redeveloped as part of the Chattahoochee Riverwalk, the four-acre site was home to one of more than 1,500 manufactured gas plants around the United States that contaminated the ground after operating from the mid-1800s through the early- to mid-1900s.

More broadly, Dennis will outline how the Columbus case relates to the legal, regulatory and physical issues policymakers deal with regarding environmental contamination in the process of urban redevelopment.

Dennis’ presentation is part of a series of environmental policy lectures presented by CSU’s Department of Political Science and MPA Program. For more information, call 706-507-8704.
