Dataset on hydrogeochemical characteristics of spring and surface waters in the complex karst catchment area of Southern Dalmatia (Croatia) and Western Herzegovina (Bosnia and Herzegovina)
Description
This dataset comprises hydrogeochemical data from karst groundwater and surface water samples in the Southern Dalmatian and Western Herzegovina catchment. It consists of one Excel file with two sheets. The first sheet, "Ions," contains the physicochemical properties of the water, including temperature (T) in ˚C, electrical conductivity (EC) in µS/cm, and dissolved oxygen (O₂) in mg/l, as well as basic anions (Cl⁻, HCO₃⁻, SO₄²⁻) and cations (Na⁺, K⁺, Ca²⁺, Mg²⁺) in mg/l. The second sheet, "Sulphur," includes the data from two sampling campaigns, with physicochemical properties, basic ions, and stable sulfur isotope values (δ³⁴S). This dataset is of great importance as it contains data collected over a monitoring period from September 25, 2013, to September 30, 2020. It is the result of the first extensive study conducted on such a large catchment area, covering over 2.300 km². The dataset is of multidisciplinary value and can be used by hydrogeologists, chemists, and other researchers or practitioners, such as water suppliers, who are dealing with water management, or environmental issues. The dataset can serve as an input for enhancing measures to protect and safeguard groundwater, identifying contaminant sources, and forming the basis for the improvement of sanitary zone delineation.
