The regional stream survey for southwestern New Brunswick (NTS 21J/2 West and 21J/3 East) was conducted during the summer and fall of 1991.

This report presents analytical and statistical data for 36 elements in stream sediments from 431 sample sites, collected at an average density of one sample per 2.5 km². Loss-on-ignition in sediments and uranium, fluoride, and pH values in waters from these sites are included in this report.
