   So called hard rocks (igneous, metamorphic and sedimentary highly cemented Prorozoic and Lower Paleozoic non-carbonate rocks), characterized by the presence of a near surface aquifer in their weathered and fractured zone form approximately 68of the Bohemian Massif area within the Czech Republic. During previous hydrogeological mapping programs and regional hydrogeological studies special attention has been paid to this hydrogeological environment. In the paper the main results achieved by former hardrock hydrogeological studies are resumed within three main categories of hydrogeological data, two of them being of quantitative nature (natural groundwater resources and the capability of a hydrogeological environment to enable groundwater abstraction) and the third qualitative one (groundwater quality). Transmissivity values (hydrogeological background) of petrological types of rocks and chemical composition of groundwaters is discussed.
   Different types of hard rocks do not seem to influence significantly chemical composition of their freatic water with only some exceptions: Basic rocks, marbles (crystalline limestones), somewhere granites and slates. Hydrochemical anomalies in some areas of the Bohemian Massif might indicate vertical hydrochemical zoning known from other shields and massifs of crystalline rocks, with presence of highly mineralized chloride-sodium ground water in the deep zones
