ABSTRACT: On October 23, 2000 the European Parliament and the Council adopted the Directive 2000/60/EC, the Water Framework Directive, hereafter referred to as the "WFD", establishing a framework for Community action in the field of water policy. This Directive forms the basic legislation for the protection of the European aquatic environment. One of the issues required by the "WFD" is to delineate adequate groundwater bodies on the territory of each member state to help the achievement of good groundwater status and to that end provides for the monitoring of groundwater bodies as well as measures to protect and restore groundwater. At present, 101 groundwater bodies were delineated on the territory of Slovak Republic. These are subdivided into three groundwater bodies "layers", following the primary division of the 141 hydrogeological rayons, sub- rayons and partial rayons for the first two layers. At first, layer of 16 groundwater bod ie s of Quaternary sediments was generated, and (at some places underlying) "layer" of pre-Quaternary groundwater bodies count s 59 groundwater bodies. Independent "layer" of 26 geothermal groundwater bodies was created beneath. Further characterisation of delineated groundwater bodies, including qualitative and quantitative status assessment should be presented in the nearest future.
