Louisville Soil Contamination
Louisville residents who live near a former insecticide plant want to know why it took officials about 25 years to test their soil for contamination.
Tim Hubbard, assistant director of the Kentucky Division of Waste Management, told The Courier-Journal that he doesn't know why the testing wasn't completed sooner.
It was only when the site's owners sought permission to put in housing that the Division took soil samples. Those found high levels of pesticides, including the now-banned DDT, as well as toxic heavy metals such as arsenic and lead.
Last year the state turned the investigation and cleanup over to the EPA's Superfund program, which deals with the nation's most polluted properties. Results of soil test from neighboring properties likely will be made public this month.
