The Peel-Caribou Staging Area, located along the Peel River, northern Yukon Territory, was used for exploratory drilling activities during the mid-1960s. Following abandonment of the project in 1975, waste materials were buried in a pit on site. An encroachment of the river on the waste pit in 1994 exposed the debris along with soils contamiated by DDT (1,1,1-trichloro-2,2-bis-(4-chlorophenyl)ethane), metals, hydrocarbons, and dichloromethane. The results of subsurface drilling in April 2000 and contaminants analyses, along with data from a geophysical investigation, indicated contaminated soils and debris were located in a 2-metre thick layer below the high-water mark of the riverbank, with an overburden of soil varying in depths [...]
