The regional stream survey for northeastern New Brunswick (NTS 21O/8 East and 21P/5 West ) was conducted during the summer of 1988 .
This report presents analytical and statistical data for 20 elements in stream sediments from 418 sample sites, collected at an average density of one sample per 2 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.

The reconnaissance surveys were managed by the Geological Survey of Canada in conjunction with the New Brunswick Department of Natural Resources and Energy (Mineral Resources Division) as part of the Canada-New Brunswick Mineral Development Agreement (1984-1989).
E.H.W. Hornbrook directed the survey.
P.W.B. Friske coordinated the operational activities of contract and Geological Survey of Canada staff.

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.
