The regional stream survey for northern New Brunswick (parts of NTS 21O and 22B) was conducted during the summer of 1985.

This report presents analytical and statistical data for 20 elements in stream sediments from 598 sample sites, collected at an average density of one sample per 8.1 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.

Other information:

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.
