Lake St. Clair is a small semi-circular lake located between Lake Huron and Lake Erie. A significant portion of Lake St. Clair is bounded by parts of the Metro-Detroit and Greater Windsor areas. A review of past studies showed that no significant study of Lake St. Clair water chemistry has been conducted in the recent past. Therefore no updated database for the lake existed. It was therefore decided to undertake a geochemical study of the water in Lake St. Clair to determine the water quality of Lake St. Clair with respect to heavy metals and certain other trace elements. Water sampling took place in the months of July, August and September of 1998. Analysis of the water samples was conducted using an Inductively Coupled Plasma Mass Spectrometer and an Inductively Coupled Plasma Optical Emission Spectrometer. A GIS database was developed to carry out spatial analysis of the results. The results were used to simulate a water quality model of the lake. Results of the Geochemical survey indicate that the Clinton River appears to be a significant source of contamination. Comparison of these results with the water quality model led to the conclusion that desorption and atmospheric deposition are playing an important role for certain elements. It is expected that this study would help further the understanding of the Lake St. Clair contamination puzzle.Dept. of Physical Sciences.
