Add to ORKGLake waters of the north-central U.S.A. arc classified into five groups, based on increasing specific conductivity and changes in ionic composition from east to west, from Wisconsin through Minnesota to North and South Dakota, The most dilute group of waters has specific conductivities <29 µmhos -cm-’ at 25°C; the most concentrated group has specific conductances that range from 7,000 to 73,000 µmhos. As conductivity increases all major ions increase, but there is a shift in cation dominance from Ca2+ to Mg2’ to Na’, and in anion dominance from HC03- to SOd2-. This shift partly reflects a westward increase in climatic aridity, and partly a westward sequence of glacial drifts from noncalcareous to calcareous and hence to calcareous with abun...
