The regional lake sediment and water survey for northern Ontario (NTS 41O) was conducted during the summer of 1986.

This report presents analytical and statistical data for 18 variables in lake sediments from 1,335 sample sites, collected at an average density of one sample per 12.6 km². This report includes values for uranium, fluoride, pH, alkalinity, calcium and magnesium in waters.
