Abstract

The St. Clair River delta, the largest in the Great Lakes area, is located astride the border between Michigan, United States of America (U.S.A.), and Ontario Canada. It resembles a classic river-dominated delta system, with a typical "birds foot" morphology The St. Clair River delta consists of six islands from west to east: Seaway, Bassett, Squirrel, Walpole, the artificial Pottowatamie, and St. Anne. This study is performed on three continuous vertical sediments cores The cores were taken along a north-south transect of Walpole island. The St. Clair River delta is composed of a premodern and modern sediments. Sediments of the premodern delta were deposited from 3 500 to 5 000 B.P. at an elevated lake level. The sedimentation of modern sediments started about 3 500 B.P. and continues to this day. Beneath the delta, lacustrine and sediments are found. The clay minerals of the day fraction are determined to identify the glacial detrital sources, the sedimentary processes and the past environmental changes. Two sites for shallow groundwater sampling were selected in the centre of Walpole Island to evaluate the environmental impact of the landfill and surficial disposal.
