The McDame (NTS 104P) reconnaissance-scale stream sediment and water survey was completed in 1978 and the resulting field and analytical data were released in 1979. A total 848 of sediment and water samples were collected from 802 sample sites.
As part of the RGS Archive Program, 847 archived sediment pulps were re-analyzed by epi-thermal INAA and this new data along with original survey results were re-published in 2000. |
