During the summer of 1970, a total of 1,105 stream sediments were collected in a 1,165 km2 area around St. Catherines, Ontario. Samples were collected from wet or dry stream channels located upstream from all road bridges in the study area. This technique provided a uniform coverage of samples sites over the area, except in the vicinity of Fonthill where there are no streams.
Cores of lake sediments were taken from 20 lakes in 5 areas: Kaladar, Cambridge, Hamilton, Belleville and St. Catherines. Within each area, small lakes were selected for core sampling; one or more cores were taken from each lake depending on conditions.
An interpretation of the study and some of the data can be found in Geological Society of America Special Paper 155.

The geographic extent of the survey is defined by the following polygons:
Covers most of 30M/3 (Niagara) on the Niagara Peninsula, southern Ontario. It is bounded to the north by Lake Ontario and to the east by the Ontario-New York border. The city of St. Catherines lies within the study area.
Covers part of the northeast corner of NTS 31C/11 (Kaladar) in the Kaladar area of southeastern Ontario. The centre of the study area is located approximately 70 km northwest of Kingston and 15 km southwest of Big Gull Lake.
Covers parts of NTS 31C/3 (Belleville), /4 (Trenton), /5 (Cambellford) and /6 (Tweed) in the Belleville area, southern Ontario. It is bounded to the south partly by Lake Ontario. The Bay of Quinte lies in the east-central part of the study area and Highway 401 runs east-west through the central part of the study area.
Covers most of NTS 40P/8 (Cambridge) in the Galt/Cambridge region of southwestern Ontario. The eastern edge of the study area is located about 25 km west of Lake Ontario. The city of Cambridge lies within the study area.
Covers part of NTS 30M/5 (Hamilton-Burlington) in the Hamilton area of southwestern Ontario. The centre of the study area is located about 13 km north of Hamilton and 9 km northwest of Burlington. Lake Ontario is located 9 km to the east.
