The Quesnel (NTS 93B) reconnaissance-scale stream sediment and water survey was completed in 1980 and the resulting field and analytical data were released in 1981. A total of 759 sediment and 750 water samples were collected from 715 sample sites.
As part of the RGS Archive Program, 1241 archived sediment pulps were re-analyzed by epi-thermal INAA and this new data along with original survey results were published in 2001. |
