(requires an Internet connection)
During the summer of 1982, a helicopter supported lake sediment sampling survey was conducted by J. Descarreaux and Associates (NTS 23M/4, 5, 6, 23L/12, 13, 24D/4, 5, 12, 13 and 24P/1, 2,3, 6-11, 14-16, 24A/1, 2,3, 6-11, 14-16, 23I/9-11, 14-16). The area covers 26000 km2. A total of 1901 samples were collected from lakes with surface area of km2. At an average density of 1 sample per 12.0 km2, it was sometimes necessary to sample bigger lakes with many sites of sampling. Lakes were sampling along their central axis, generally in the center of that axis.
Samples were analysed for:
|Ag, Al, B, Ba, Be, Ca, Cd, Ce, Co, Cr, Cu, Eu, Fe, K, La, Li, Mg, Mn, Mo, Na, Ni, P, Pb, Sc, Sm, Sr, Th, Ti, V, Y, Zn||
|Hg||flameless atomic absorption|
|pH, Loss on ignition (LOI)|
The data are published in Open File DP 82-16, Department of Energy and Resources, 1982. Subsequently, samples were analysed for arsenic and the data are published in Open File DP 83-18, Department of Energy and Resources, 1983.

The geographic extent of the survey is defined by the following polygons:
Covers parts of NTS 23M/4 (Lac Bresolles), /5 (Lac Louet), /6 (Lac Maurel), 23L/12 (Lac Robutel), /13 (Lac Druillon), 24D/4 (Lac Arbique), /5 (Lac Degrais), /12 (Lac Le Boux), /13 (Ruisseau Soupras), most of 24P (Pointe Le Droit), 24A (Lac Brisson) and 23I/9 (Signal Hill), /10 (Newfoundland-Quebec), /11 (Newfoundland-Quebec), /14 (Lac Potel), /15 (Lac Bonaventure), /16 (Lac la Pinaudière). The Rivière George region is situated in the Nord-du-Québec area. It is bounded to the east by the Labrador border and by latitudes 54°35' and 57° and longitudes 63°23' and 65°.
