Federal officials say they hope to begin work this year to rebuild an underground barrier that holds back tainted soil and groundwater at the site of a former central Indiana auto parts plant.
The U.S. Environmental Protection Agency approved construction of the clay barrier in 2006 to contain hazardous materials produced by a Delco Remy plant in Anderson demolished in 1996.
But The Herald Bulletin reports subsequent testing showed the barrier leaked and groundwater was oozing through gaps in the structure.
The site is tainted with industrial waste that accumulated over several decades during which the Delco Remy plant made car horns, turn signals and other auto parts.
EPA site manager Don Heller says he hopes field work for the project can be completed this year.
