The regional stream survey for southern New Brunswick (parts of NTS 21G, 21H) was conducted during the summer of 1986.
This report presents analytical and statistical data for 20 elements in stream sediments from 753 sample sites, collected at an average density of one sample per 5.9 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.

Gold was usually determined on 10-gram sample, allowing a detection limit of 1 ppb; sample weights less than 10 grams resulted in a detection limit of 2 ppb. Sample weights less that 5 grams resulted in a detection limit of 4 ppb.
