Year of Collection:  1988

Survey Type:  Regional Stream Survey

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.

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.
