Geological Survey of Canada (GSC) Open File 2184 / British Columbia Ministry of Energy, Mines and Petroleum Resources (BCMEMPR) Regional Geochemical Survey (RGS) 26 presents analytical data for 21 elements in moss-mat or stream sediments from 855 sample sites, and statistical data for 922 sites, collected at an average density of one sample per 14.2 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from 855 sites are included in this report.
