Detailed research on the content of heavy metals in ground and surface waters in the upper Sanna River catchment was initiated in 2013. The investigations were conducted in one of the most promising areas of potential shale gas extraction, in which the Frampol 1 test wellbore was drilled in 2012 (SE Poland, Roztocze Region). In the area of the wellbore, hydrochemical analyses of the waters of the river drainage zone were performed. Water was sampled from six objects representing soil water, porous groundwater, fissure-layer groundwater, and river water. The hydrological regime of groundwater and surface water was analysed based on data obtained from automatic recorders of water levels and results of periodic measurements of water flow. In 2013, water was sampled on a monthly basis for determination of the levels of Ba, Sr, Al, Fe, Mn, Zn, Cu, Cd, Co, Cr, Ni, As, V, Rb, Pb, Th, and U. The analysis results showed that the concentration of Sr was usually in the range of 100–400 µg/L, Fe 10–100 µg/L, Ba 10–40 µg/L, and Mn, Al, and Zn 1–10 µg/L. The concentration of the other metals generally did not exceed 1 µg/L. The concentrations of the elements analysed in the zone of drinking water intake were within the range specified by Polish and WHO standards. Significant differences were found in the metal content in the analysed waters; they were related to the water intake site, form of land management, and hydrometeorological conditions. The highest metal content was recorded in soil and river waters and the lowest in the spring waters of the main water-bearing horizon. At the current stage of the research, no impact of the Frampol 1 shale gas exploration wellbore on the metal content in the upper Sanna River catchment was found.
