Leaching of chromium, copper and arsenic from utility poles treated with chromated copper arsenate

The objectives of this study were to examine leaching of chromated copper arsenate (CCA) from treated timber and to determine the cation exchange capacity (CEC), pH and total organic carbon (TOC) of the contaminated soil samples. A total of 114 surface soil samples were collected around 28 Douglas fir utility poles at distances of 0,0.30, and 0.60m and 3 background samples were collected at a distance of 7.0m from the poles.Also a freshly treated, 1.50m long utility pole section was suspended outside in a large cyclinder to collect runnoff. The Cu:As:Cr (molar) ratios of the average metal contents in the soil samples collected at a distance of 0m and in the runoff from the pole segment, were 100:46:56 and 100:44:57, respectively.For the covering abstract of this conference see ITRD E132435.
