Water Well Information Systems (WWIS)

Point data representing water well locations in Ontario. Using the well ID number, a manual search of the printed Groundwater Bulletin Report (MapBk TD 405 O58 2006) will provide further details including elevation, water kind, water use, depth to bedrock, depth to water and soil profiles. All details are available through the search tool.
