Abstract

The groundwater occurrence and quality within crystalline rocks of Sudety Mts based on water intakes study (SW Poland).Summary. Results of field measurements and study on groundwater occurrence in hard rock are presented based on data from water intake. The main goal of the research (field and lab) was to determine: conditions of occurrence, storage and groundwater flow and intake within crystalline rocks as applicable for water supply methods and choosing best technique of field survey for the preferential zones rich in groundwater within crystalline rocks, best methods of water intake, and monitor changes of water quality during the last 10 years. The final effect of the project was a documentation presenting optimal criteria to choose the water intake types within crystalline rocks, the proposal of a set of obligatory physical–chemical analyses during water intake documentation as well as creation of a relational data base Krystal 1, which includes the basic data of investigated water intakes with the physical–chemical results of 142 samples taken in the field. The best methods for water intake were horizontal drainage intake and intake based on natural spring. Groundwater quality improvement in the last decade was manifested by increase of water pH and recovery toward natural chemical character of the ground waters.
