The Hydrogeological Information System (HIS) contains the physical characteristics of wells and boreholes (location, depth, stratigraphy encountered, etc.) mainly from drilling reports transmitted by well drillers for groundwater sampling installations serving private drinking water residences. The geographic coverage corresponds to all of Quebec although most of the data are found in the south of the province. A monthly update is made. SIH data can be useful for hydrogeology professionals, the academic community and a wider audience in order to make interpretations on portions of territory, for example on the depth of the rock in a sector, or to consult more precise points of information such as the description of a specific identified well.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The term “geotechnical investigation site” refers to locations where geotechnical (surveys and instrumentation) and geophysical data are available. These data include: - **Geotechnical investigation sites (site_inv_geotech_p) :** Geotechnical surveys produced by or for the Ministry from the 1990s, from the active database of the Directorate of Geotechnics and Geology (DGG). Data is added as and when validated. - **BDG geotechnical investigation sites (site_inv_geotech_bdg_p) :** Geotechnical drilling and drilling from an “inactive” database entrusted to the DGG by the Ministry of Energy and Natural Resources (MERN), since the mid-1980s. These are drilling and survey data compiled by the MERN in the 70s and 80s for “predictive” or “geotechnical soil suitability” mapping campaigns.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

These projects aim to draw up a realistic and concrete portrait of groundwater resources in municipal territories in southern Quebec. They were carried out by university research teams, in partnership with regional actors, in order to provide the knowledge essential for sustainable and integrated management of resources in a context of climate change. This knowledge is available to the general public, in the form of databases, cartographic representations, summary and scientific reports and cartographic atlases, in various formats, for almost all of the municipal territory of southern Quebec. In particular, they provide information on the quality, quantity and vulnerability of the resource. They are useful for water professionals working for example in the field of water research for municipal water supply, resource protection or university research. They are also useful in ensuring the compatibility of development and land use planning with the protection of water resources.
