The regional lake survey for northern Labrador (NTS 14E and parts of 14F, 14L, 24H and 24I) was conducted during the summer of 1985.
This report presents analytical and statistical data for 17 elements in lake sediments from X sample sites, collected at an average density of one sample per 13 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.
