Analytical results from the previous investigation indicate the presence of widespread
contamination on the site and the necessity of an expanded Remedial Investigation/Feasibility
Study. Additional Investigative work was completed in 2005 to clear up discrepencies in the
data. A report describing the addtional investigation work, the results and the conclusion was
submitted in April 2006 and a revised report was submitted in January 2008.
A PRAP was completed for the OU 1 and 2 and the proposed remedy is No Action with the
imposition of an Institution/Engineering control. OU 3 along with the river sediments will be
deferred for further investigation and evaluation for an appropriate remedial action. A public
meeting was held on March 18, 2008. The ROD was signed on March 31, 2008.
