Procedure details

A geological survey comprises all general geological, raw material geological, engineering geological, geophysical, mineralogical, geochemical, pedological, geothermal, hydrogeological and geotechnical measurements and recordings of the earth's surface, the geological subsurface, the soil or the groundwater by means of prospecting, drilling, field or borehole measurements and other exploration methods such as remote sensing.

All geological investigations must be notified to the Bavarian State Office for the Environment (LfU) as the competent authority within the meaning of the Geological Data Act (GeolDG) two weeks before the start of the work by the party carrying out the investigation for its own account or for the account of a third party.

The notification of geological investigations in accordance with the GeolDG does not replace the obligation to notify earth excavations or boreholes in accordance with the Water Resources Act (§ 49 WHG), the Federal Mining Act (BBergG) or the application for water law or mining law procedures. These must be submitted separately to the authorities responsible for the investigation site in compliance with the statutory deadlines.

Data on the geological subsurface was obtained during an investigation within the state of Bavaria.

The LfU provides an online application to fulfill the legal obligation to report geological investigations (see "Online procedure").

The online application "Geological survey online" allows you to

  • for a project with one or more individual investigations, to enter the contact details of the notifier as well as the client and the planner once in all forms,
  • navigate in a map application to the survey location down to parcel level,
  • enter technical information on the survey method in the form fields after marking the survey locations,
  • conveniently send the data to the LfU online after the final check,
  • prompt confirmation of receipt of the report by the LfU by e-mail.

The notifier receives a unique identification number (BID) for each survey entered.

After completion of the geological survey, the results obtained (technical and assessment data) must be transmitted to the LfU in accordance with the requirements of Sections 9 and 10 GeolDG.

none

All geological investigations must be notified at least two weeks before work begins.

After completion of the geological investigation, the technical data must be submitted to the LfU within 3 months and the assessment data within 6 months.

  • Mining; display of a borehole

    Drillings that are not drillings for the exploration of mineral resources and that penetrate deeper than 100 m into the ground must be reported.

  • Well drilling; display
    If you want to drill a well, you must indicate this.
  • Earth excavation; display

    Anyone who drills a borehole, builds a well or carries out other work that penetrates so deeply into the ground that it could affect the groundwater must report this to the authorities.

  • Geological information and data; retrieval

    The State Office for the Environment carries out the state geological survey by means of its own geological investigations and on the basis of geological investigations by third parties and ensures that the data is made available to the public.

  • Geotope register; geotope research
    The Bavarian State Office for the Environment (LfU) records important geotopes throughout Bavaria, assesses their worthiness of protection and, if necessary, initiates suitable protection, conservation and maintenance measures.
  • Rocks and soils; carrying out laboratory tests

    The State Office for the Environment carries out chemical and physical laboratory tests on rocks and soils. At the Raw Materials Analysis Center, solid and loose rocks are examined with regard to their suitability as raw materials.

  • Rock and soil samples; setting up and managing collections
    The Bavarian State Office for the Environment (LfU) is building up working and voucher collections as a central collection point for rock and soil samples from Bavaria and will continue to do so on an ongoing basis.
  • Heat pumps and geothermal probes; notification of boreholes for installation

    Drilling for the installation of geothermal probe systems and groundwater heat pumps must be reported to the responsible district administrative authority in order to protect the soil and groundwater against contamination.
