After correcting those ages for the fractionation of C-14 in calcite and for the radioactively inert CO2 in the atmosphere, we find residual ages, caused by the hard water effect, of about 250 years for Lake Michigan and 440 years for Lake Huron.}, issn = {0921-2728}, doi = {10.1007/Bf00682596}, author = {Rea, D.
