Geological Survey of Canada (GSC) Open File 2040 / British Columbia Ministry of Energy, Mines and Petroleum Resources (BCMEMPR) Regional Geochemical Survey (RGS) 23 presents analytical and statistical data for 22 elements in moss-mat and stream sediments from 1,140 sample sites, collected at an average density of one sample per 10.8 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
