The regional lake survey for west Labrador (NTS 23G and 23H) was conducted during the summers of 1978 and 1982 .

This report presents analytical and statistical data for 15 elements in lake sediments from XX XX 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 Cooperative Mineral Program (1982 - 1984).

E.H.W. Hornbrook directed the Geological Survey of Canada activities.

N.G. Lund was responsible for open file production.

A.C. Galletta was responsible for data management.

F. Williams of the Cartographic section supervised map preparation.

Plotting facilities were made available through the Computer Science Centre, EMR.
