The regional lake sediment and water survey for northwestern Ontario (parts of NTS 52D and 52E) was conducted during the summer of 1988 .
This report presents analytical and statistical data for 18 variables in lake sediments from 590 sample sites, collected at an average density of one sample per 16.9 km². This report includes values for uranium, fluoride, pH, alkalinity, calcium and magnesium in waters.
