1. Legal basis of the sensitivity maps

The aim of Government Decree 219/2004. (VII. 21.) on the protection of groundwater1 (hereinfafter referred to as GD) is to determine tasks, rights and obligations associated with

  • a) the ensuring and maintaining of the good status, and
  • b) the progressive reduction and prevention of pollution of groundwater;
  • c) a sustainable water use based on the long-term protection of available groundwater resources
  • d) the remediation of the geological medium.
Sensitivity classification of areas serves the purpose to achieve the above goals.

Acc. to Article 7 of GD:"
  • (1) Areas should be classified on the basis of sensitivity of the groundwater status and protection of the water quality thereof taking into consideration the recharge of groundwater, hydraulic conductivity of the geological medium, further the areas under special protection.
  • (2) In terms of groundwater sensitivity, areas can be classified as areas of extremely high sensitivity, sensitive and less sensitive areas.
  • (3) Criteria and detailed specification for classification mentioned in paragraph (2) with presentation of categories and their further division are set out in Annex 2. of this decree.
  • (4) The sensitivity of a given, defined area is determined in the official ruling on the basis of the 1:100 000 scale pollution sensitivity map approved by the minister and available at the regional inspectorate and the Water Management Research Plc. (VITUKI Kht.), or its legal successor.
  • (5) The inspectorate may apply special sensitivity classification for a defined area based on a map more detailed than the one mentioned in paragraph (4) and made on the basis of local investigations carried out by, or for the user of the environment in compliance with the requirements set forth in Annex 2.
  • (6) Administrative areas of municipalities are categorised on the basis of the map defined in paragraph (4) by the highest of sensitivity categories covering at least 10% of their territory.
  • (7) The minister sets forth the classification of the administrative areas of municipalities carried out according to the aspects stated in paragraph (3) in a decree authorised by the provision set out in clause m) of paragraph (8) of article 110 of Kvt.
  • (8) The minister shall review the countrywide processing of the areas completed acc. to paragraph (4), and their classification based thereupon, simultaneously with the preparation of the river basin management plan specified in a separate piece of legislation."
The aspects of sensitivity classification of areas sensitive in terms of groundwater status are laid down in Annex 2 of GD, which entered into force on January 1, 2005 conjointly with the Ministerial Decree 27/2004. (XII. 25.) KvVM on the classification of settlements located in sensitive areas in terms of groundwater status amended by the Ministerial Decree 7/2005. (III. 1.) KvVM.

Maps showing the spatial distribution of the relevant sensitivity categories have been compiled to promote the implementation of GD and are downloadable at the homepage of KvVM. This commentary describes their content, the source background information, the methods applied in editing them and their use in practice.
