The British Columbia Geological Survey, Ministry of Energy and Mines has been involved in reconnaissance-scale stream sediment and water surveys since 1976. This program has generated high-quality stream and lake sediment and surface water data from geochemical surveys carried out across Canada. In British Columbia the National Geochemical Reconnaissance (NGR) program, known as the Regional Geochemical Survey (RGS), has covered roughly 75 percent of the province with stream sediment and stream water sampling at an average sample density of one sample per 13 square kilometres. A MicrosoftTM Access
database contains all of the field and analytical information from 61,425 samples collected and/or reanalysed by the BC Geological Survey, the Geological Survey of Canada and Geoscience BC from 1976 to March 2011. The figure to the right shows the RGS sample coverage.
