The B.C. Ministry of Energy, Mines and Petroleum Resources (MEMPR) has been involved in reconnaissance-scale stream sediment and water surveys since 1976. This joint federal-provincial initiative was originally referred to as the Uranium Reconnaissance Program (URP). In 1978 the provincial program was renamed the Regional Geochemical Survey (RGS) and in 1987 the Province began to independently administer surveys conducted in British Columbia. As part of Canada's National Geochemical Reconnaissance (NGR) program, the RGS program continues to maintain sample collection, preparation and analytical standards established by the Geological Survey of Canada. New drainage surveys and archive sample re-analysis has been undertaken by Geoscience BC after 2006 and the results incorporated into the RGS database. To date, over 59,600 stream sediment and water samples have been collected from 58 - 1:250,000 NTS map sheets covering approximately 75 per cent of the province. Determinations for up to 60 metals, field observations and sample location coordinates are compiled into B.C.’s largest and most comprehensive stream sediment and water geochemical database.
