ABSTRACT: Large portion of today´s hydrogeological practice deals with problems in highly urbanised and industrial areas. A huge concentration of various anthropogenous impacts to groundwater regime and groundwater quality is a typical feature of this environment. The article of recherche character presents basic specification and description of these impacts. Basic types of hydrogeological tasks in urban and industrial environment are characterised together with issuing specialities concerning methodology of fieldwork, data processing and evaluation. These are two typical specifics of hydrogeological work in urbanised environment: (1) huge amount of data of varied character, format and reliability that must be gathered and processed and (2) interdisciplinary approach to many types of hydrogeological tasks.
