The regional stream survey for northern Labrador (NTS 14M and parts of 14L, 24I, 24P, 25A) was conducted during the summer of 1986.
This report presents analytical and statistical data for 20 elements in stream 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.

The reconnaissance surveys were undertaken by the Geological Survey of Canada in conjunction with the Newfoundland Department of Mines and Energy under the Canada - Newfoundland 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.
H.R. Schmitt coordinated open file production.
A.C. Galletta managed the digital geochemical data and provided computer processing support.
D.J. Elwood developed software to raster plot open file value, symbol and regional trend maps.
The plotting was done by Canada Lands Data Systems staff at Environment Canada, Hull, Quebec.
M. McCurdy and S. Cook processed incomming and outgoing materials, supplies and samples.
Computing, plotting and open file text printing services provided by the Computer Science Centre, EMR.
J.Yelle and F. Williams of the Geological Information Division supervised the preparation of the open file base maps by Cartography Unit A-2.
