Summary of Lemon Lane Position Paper

Gareth J. Davies, of Oak Ridge, Tennessee, is a geologist widely experienced in karst geology and hydrology. He provides technical support to COPA and has pointed out that "recent work by CBS in relation to ground-water tracing, geophysics, and drilling in the vicinity of the Lemon Lane Landfill could support a single conduit model, however, proposed treatment scenarios and partial excavation proposals are completely untenable. The published literature does not support the efficacy of treatment at all, and leaving part of the waste in sinkholes might have dire consequences on the treatment system, springs, and surrounding community because of an unpredictable source-release scenario, that would be an interminable issue. Due to the sketchy nature of history of past Lemon Lane activities, the source release problem (related to a partial excavation proposal) is as much a safety issue as a contaminant problem and cannot be mitigated by anything less than the alternative of complete excavation, coupled with appropriate treatment at Illinois Central Spring, other discharge locations known to be connected to and impacted by the landfill and other appropriate drilled wells at locations determined from geophysical data."
