The regional lake sediment and water survey for central northern Ontario (parts of NTS 42E, 42L and 52H ) was conducted during the summer of 1989.
This report presents analytical and statistical data for 43 variables in lake sediments from 1,059 sample sites, collected at an average density of one sample per 7.9 km². This report includes values for uranium, fluoride, pH, calcium, magnesium and alkalinity in waters.
