N2 - The results of the study of hydro geochemical features and assessment of the quality of groundwater in the watercarrying complex of the Upper Jurassic sediments of the southwestern regions of the Crimean Peninsula for drinking and agricultural water supply are presented. Pressure stratalfissured and fissure-karst waters are confined to the Middle-Oxford-Kimeridzhsky aquifer. It was established that in the studied region fresh groundwater is developed with a total mineralization of up to 1 g/dm 3 and lower than HCO3-Ca, HCO3-Ca-Mg, more rarely HCO3-Ca-Na and Na-Ca composition with the first being dominant. The highest quality groundwaters are characterized by HCO3-Ca composition with a total salt content of up to 0.6 g/dm 3 . They have been studied within the Rodnikovsky section of the West-Crimean groundwater deposit. Waters of satisfactory quality are characterized by HCO3-Ca and HCO3-Ca-Mg composition and were found in wells located near the villages of Rossoshanka, Orlinoye, Plotynnoye and Golubinka. Low-quality water was determined in the wells of the villages of Sokolinoye and Cher-norechye, north-west and north-east of the Rodnikovsky water abstraction.
