Abstract
The characteristics of waters of the Bruce Peninsula, a low-lying, karstified dolomite surface at latitude 45 N, were investigated. A total of 250 samples representing six hydrochemical environments were collected. These environments included: Georgian Bay and Lake Huron; inland lakes; rivers and streams; wetlands; conduit-flow springs; and diffuse-flow springs. The seasonal behavior and chemical separation of these waters are examined. Except for Georgian Bay and Lake Huron, the waters of the peninsula were very hard, ranging from 180-320 ppm Ca(2+) plus Mg(2+) (as CaCO3), and displayed increasing hardness as the summer season progressed. Surface recharge and conduit-flow springs were generally saturated with respect to calcite and dolomite. Only diffuse-flow springs, which are among the hardest of waters, are commonly undersaturated. These waters are also the easiest to distinguish chemically, and results of a linear discriminant function analysis suggest that other waters of the peninsula represent a single class.
