Geological risks - Hydrogeological objects

Description

The dataset is part of the data focusing on groundwater contamination. This consists of hydrogeological objects - exploration and monitoring wells, wells, pumped wells (i.e. objects regularly pumped mainly for technological purposes), remediation wells and wells interfering with non-ogeneous aquifers (if the well interferes with non-ogeneous aquifers and at the same time is a collecting well, it is included in wells interfering with non-ogeneous aquifers). Furthermore, the data focus on the documented or predicted transit of contamination (ClU and NEL). Part of the data is the name of the object, the use (type) of the object, or scanned water management decisions on groundwater management - permits for pumping groundwater (decisions are also attached to the areas for which decisions were issued). The data also include well documentation (the year of excavation, localization, height measurements, data on the depth of the well and its technical design), petrographic description of the well core and drilling profile stratigraphy (for wells interfering with non-ogeneous aquifers), data on the groundwater level and links to the reports from which the data were drawn. The well documentation shall also include the contaminant concentrations determined at the last three groundwater abstractions, if any. The contaminants monitored are petroleum substances (C10-C40 hydrocarbons), CIU (chlorinated hydrocarbons), BTEX (benzene, toluene, ethylbenzene, xylene), PAHs (polycyclic aromatic hydrocarbons), phenols, PCBs (polychlorinated biphenyls) and heavy metals. The concentration of individual contaminants is compared with the pollution criterion set by the MoE MP in 2014. 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.
