Province / Territory: Newfoundland & Labrador
Funding Source: Federal and Provincial

The infill stream and lake survey for eastern Labrador (parts of NTS 13J and 13O) was conducted during the summer of 1987.
This report presents analytical and statistical data for 20 elements in stream and lake sediments from 309 sample sites, collected at an average density of one sample per 3 to 5 km². Loss-on-ignition in sediments, and uranium, fluoride, and pH values in waters from these sites are included in this report.

The infill geochemical survey was carried out by the Geological Survey of Canada in conjunction with the Newfoundland Department of Mines and Energy under the terms of 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 and edited open file production.
A.C. Galletta and D. Wright managed the digital geochemical data, provided computer processing support and developed software to plot the open file symbol and regional trend maps.
Computing services provided by the Computer Science Centre, EMR.
The plotting was done by Canada Lands Data Systems staff at Environment Canada, Hull, Quebec.
H. Gross developed microcomputer software to produce data listings and summary statistics.
Open file base maps were prepared by the Geological Information Division, Catography Unit A-2 and Terra Surveys Ltd., Ottawa.
