The regional lake sediment and water survey for east-central Ontario (NTS 31D, 31E, 41H) was conducted during the summer of 1982.
This report presents analytical and statistical data for 34 variables in lake sediments from 1,033 sample sites, collected at an average density of one sample per 17.8 km². This report includes values for uranium, fluoride, pH and 17 additional variables in waters.
