Description: The Ontario Geotechnical Boreholes database contains Geotechnical Borehole records. Each well provides information on the Geological Stratum identified down hole as well as the depths.
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.
Boreholes of all types contribute to the delineation of the earth's subsurface, which includes aquifers. The extent and character of aquifers is important to Source Water Protection Planning and to broader water management. Accuracy of borehole location and elevation data varies depending on data source. <<REFERENCE>> Ontario Geological Survey 2020.

La base de données des forages géotechniques de l'Ontario contient des enregistrements de forages géotechniques. Chaque puits fournit des informations sur la strate géologique identifiée au fond du trou ainsi que sur les profondeurs.
Un trou de forage est un terme général désignant un puits étroit creusé dans le sol, verticalement ou horizontalement. Un trou de forage peut être construit à des fins très diverses, notamment pour l'extraction d'eau ou de fluides (comme le pétrole) ou de gaz (comme le gaz naturel ou le méthane), dans le cadre d'une étude géotechnique ou d'une évaluation environnementale d'un site, pour l'exploration minière ou comme trou pilote pour l'installation de piliers ou de services publics souterrains. Cette base de données contient un enregistrement continu des strates pour chaque forage ainsi que pour les géocolonnes. Une géocolonne est une collection d'informations provenant d'un examen du substrat exposé, comme dans une paroi de carrière ou le long d'un passage routier.
Tous les types de forages contribuent à la délimitation du sous-sol terrestre, qui comprend les aquifères. L'étendue et la nature des aquifères sont importantes pour la planification de la protection des sources d'eau et pour la gestion de l'eau en général. La précision des données relatives à la localisation et à l'altitude des forages varie en fonction de la source des données.
