CHEMTURA'S PRETEND CLEANUP OF GP1 & 2 STARTING

Over a year ago CPAC issued a Media Release titled "Chemtura Public Advisory Committee (CPAC) Opposed to Chemtura's Plan for the Remediation of Gravel Pits 1 and 2". It was dated July 31, 2012. As CPAC had mostly likely been misled by Chemtura and the M.O.E., they indicated in their Media Release that the Remediation was voluntary. One of the key pieces of evidence of contamination, probably including more Dioxins and DDT, was Conestoga Rovers March 2012 report identifying strong chemical odours, soil staining and elevated vapour readings from 2 to 5.5 metres below ground surface. The proposed cleanup starting this week will remove all of one foot of topsoil from only one of the two pits. This evidence of chemical contamination years to decades after the east side pits were decommissioned is also very indicative of DNAPL (dense non-aqueous phase liquids) contamination. These would be liquids with a low water solubility that are denser than water and thus sink through the aquifer. Clearly they will never be found in the top one foot of a contaminated site. Also of interest is that both Dioxins and DDT have the chemical characteristics to be DNAPL chemicals and indeed in the presence of multiple solvents available would so behave.
