The Pemberton (NTS 92J) reconnaissance-scale stream sediment and water survey was completed in 1981 and the resulting field and analytical data were released in 1982. A total of 852 sediment and 848 water samples were collected from 806 sample sites.
As part of the RGS Archive Program, 805 archived sediment pulps were re-analyzed by epi-thermal INAA and this new data along with original survey results were re-published in 1994. |
