The regional stream survey for central British Columbia (NTS 93J) was conducted during the summer of 1985.

This report presents analytical and statistical data for 19 elements in stream sediments from 1, 088 sample sites, collected at an average density of one sample per 13.3 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
