Azotany w wodach jurajskiego piętra wodonośnego w rejonie Olkusza
(Wydawnictwa AGH, 2010) Żurek, Anna J.; Czop, Mariusz; Motyka, Jacek
Jurassic aquifer represents the Major Groundwater Basin (MGWB) 326 which is located in Upper Jurassic carbonate rocks. The hydrodynamic conditions in the Jurassic aquifer are very complex, with different types of hydraulic connections with neighbouring aquifers. Therefore the quality of the Jurassic aquifer has affected groundwater quality in Quaternary and Triassic rocks. Nitrates have been the main indicator of groundwater contamination. The regime of springs located in the study area (high fluctuation of discharge and temperature) indicates local drainage. The quality of spring-water has reflected the land use of spring recharge area. The chemistry of deep well-water has shown the quality variation of regional flow system water. Nitrate variability in spring-water (period 2001-2008) and in well-water (1995-2007) has indicated the regional trends of groundwater quality changes in the Jurassic aquifer near Olkusz.

Wpływ czynników geogenicznych i antropogenicznych na skład chemiczny wód podziemnych w Krakowie
(Wydawnictwa AGH, 2009) Kleczkowski, Antoni S.; Czop, Mariusz; Motyka, Jacek; Rajchel Lucyna Z.
Groundwater in the area of Kraków are present within two diversified hydrodynamical and also hydrochemical zones. The upper zone with active recharge from precipitation is connected with Quaternary sandy deposits and shallow Cretaceous and Jurassic carbonates. Non-polluted groundwater within upper zone is characterised by relatively low TDS and has predominantly the $Ca-HCO_{3}$ hydrochemical type. The lower zone of the groundwater is occurred below the impermeable Miocene clays within permeable Tertiary deposits and also Mesozoic carbonate rocks. Recharge of the lower zone is limited and flow velocities of the groundwater are relatively very low. The TDS of the groundwater in the lower zone range from a few to more than ten of grams per litre, in addition the predominance of chloride, sodium and sulphate ions is also observed. The therapeutic, mineral water of the Kraków spas (Mateczny and Swoszowice) is origin from the lower hydrochemical zone. The main anthropogenic factor with predominant influence on the chemical composition of the shallow Quaternary aquifer on the Kraków area is connected with a large number of the contaminant sources. The main significance with the group of contaminant sources has a accumulations of the anthropogenic soils (embankments), and also the cultural deposits containing the organic, communal garbage, gathered in the oldest part of Kraków, as well the cultural deposits containing the organic, communal garbage.

Wpływ głębokiej eksploatacji węgla brunatnego na zmiany środowiska wodnego w rejonie Kopalni »Bełchatów«
(2007) Motyka, Jacek; Czop, Mariusz; Jończyk, Waldemar; Stachowicz, Zbigniew; Jończyk, Ilona; Martyniak, Renata
Brown coal exploration in the Bełchtów open-pit is connected with intensive and deep drainage of the groundwater from Quaternary, Tertiary and also Cretaceous-Jurassic aquifers. Drainage of the high permeable aquifers has led to the formation of the extensive zone of the hydrodynamical changes of water environment. Bełchatów open-pit cone of depression has an a area of about 450 $km^{2}$. Within central part of this cone in the vicinity of the Bełchatów open-pit, groundwater table was highly lowered, on the order of tens metres. The next influence of the mining activity in Bełchatów open-pit is connected with changes in surface water budget, mainly in decreasing in groundwater recharge of the cachtments. Drainage of the groundwater is a reason for formation of the anthropogenic, modern vadose zone with availability of the oxygen. Groundwater quality deterioration within cone of depression is connected with geochemical processes of the sulphide minerals oxidation, buffering of the acid mine drainage and formation of the highly soluble secondary sulphate minerals and also occurrence of the Na-CI groundwater in the »Dębina« salt dome area. Monitoring system of the water environment in the vicinity of Bełchatów open-pit gave the possibility for observation of the water environment and also for planning of the remediation scenarios.
