Geological risks - Neogene water areas

Description

These are areas where there is a risk of contamination of deep aquifers of non-genic waters, because above the collector of non-genic waters there is no overlay insulator of non-genic clays ensuring the natural protection of non-genic waters against the ingress of contamination. The data distinguish between places where an overlay isolator of neogeneous clays is missing above the neogene collector and the collector is covered only by a quaternary isolator, and places where a nonogeneous and quaternary isolator is missing above the neogeneous collector and the nonogeneous collector is directly connected to the quaternary collector. In such high-risk areas, it is recommended to comply with stricter protective conditions when placing high-risk plants: to provide the reinforced risk areas with restraint systems, to infiltrate only rainwater without the risk of pollution, not to place operations at risk from the point of view of the release of contaminants into the rock environment As part of the preparation of projects for new construction, it is appropriate to prepare a hydrogeological assessment, addressing potential risks of the projected construction for the quality of groundwater and risks from the point of view of the foundation of the construction (e.g. the risk of an enormous inflow of groundwater into the construction pit - e.g. in the building pit. Komárov, Černovice). The data are part of the passport of geology, hydrogeology and engineering geology (now Georisks) of the city of Brno, which was created in 2004 and is always updated by an external company at the end of the year. General was created for employees of the authorities who professionally comment on investment projects, project documentation or issue decisions according to the relevant laws (Building Act, Water Act). It is now also used by contributory organizations (e.g. KAM) and provided as a basis for the processing of studies commissioned by the Statutory City of Brno (SMB). More detailed information can be found in the documentation. The data is in the GCS WGS84 coordinate system.
