Environmental impact of CCA poles in service
1997 - IRG/WP 97-50087
Soil samples from different depths and distances from CCA treated utility poles in Canada were analyzed for copper, chromium and arsenic content for a number of soil types, two wood species red pine (Pinus resinosa) and jack pine (P. banksiana) and different pole ages in service. A limited number of poles were equipped with water traps to collect rain water that dripped down the poles and where su...

1995 - IRG/WP 95-50043
The above ground portions of lettuce and rye grass grown in CCA contaminated soil collected at the base of CCA-C treated poles in service did not absorb appreciable amounts of copper, chromium and arsenic, even at soil concentrations above the recommended levels for soil remediation for agricultural uses. At high soil arsenic levels whole radish plants absorbed more As, but not the other elements....
