Ground water samples from domestic wells were collected in 3 phases in the St. Lawrence Lowlands, Estrie, Beauce and Bas St-Laurent areas:

Region	Year of Sampling	# Samples	Surface Area (km²)	Density	Analysis
Beauce	1976	260	175	1 sample/2.1 km²	Cu, Pb, Zn, Ni, Co, Mn, As, Cd, Mo, Fe, Ca, Mg, Na (atomic absorption), Li, K (atomic emission) and F (specific electrode).
Thetford-Mines	1983-1984	4495	10600	1 sample/2.1 km²	Cd, Co, Cu, Mo, Ni, Pb, As (atomic absorption), K, Li, Na (atomic emission), Ba, Ca, Fe, Mg, Mn, Zn (inductively plasma emission), U (fluorimetry), SO₄, Cl (colorimetry), F, pH (specific electrode).
rest of territory	1983-1984	14200	23000	1 sample/2.1 km²

The geographic extent of the survey is defined by the following polygons:

Covers NTS 22C/3 (Trois-Pistoles), the west half of 21N (Edmundston), 21K/12 (Saint-Magloire), /13 (Saint-Pamphile), most of 21L (Quebec) and 21E (Sherbrooke), the northeast corner of 31H (Montreal), 31I/1 (Saint-Léonard-d'Aston), /2 (Yamaska), /8 (Becancour). The region is bounded to the north by the St. Lawrence River, to the south by the USA border, and by longitudes 69°W and 73°W. It includes the cities of Sorel and Trois-Pistoles.
