Retirement note: please note that this dataset has been retired and replaced by Ontario Borehole Database, which is available from the Land Information Ontario (LIO) Warehouse.
A borehole is the generalized term for any narrow shaft drilled in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes including the extraction of water or fluid (such as oil) or gases (such as natural gas or methane), as part of a geotechnical investigation or environmental site assessment, for mineral exploration, or as a pilot hole for installing piers or underground utilities. This database contains a continuous log of strata for each borehole as well as for geocolumns. A geocolumn is a collection of information from an examination of exposed substrate, such as in a quarry wall or along a roadway passage.
All measurements are metric. All depths are relative to the surface elevation.
Supplementary tables (including a look-up table) can be used and are available for download from the additional documentation section. Supplementary look-up table descriptions are available in the Data Description document, which is available for download from the additional documentation section.
