Some Aspects of the Origin of the Naturally Occurring Sodium Chloride Waters in Eastern Ontario

This study examines the combined characteristics, as reflected by water types and similarity groupings, from major ion chemistry of groundwater samples collected by different agencies over a period of more than 60 years in the Southern Ontario. Based on the location of wells that have the same water types and similarity groups (particular characteristics within the sodium chloride waters), this study highlights a possible salinity impact upon the groundwater along the low lying areas of the St. Lawrence Platform, likely as a result of the deposition of sediments from the former Champlain Sea in this area
