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)

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.本数据集收录了达尔马提亚南部与黑塞哥维那西部流域内喀斯特地下水（karst groundwater）与地表水（surface water）样品的水文地球化学（hydrogeochemical）数据。该数据集以单个Excel文件存储，内含两个工作表。首个名为"Ions"的工作表收录了水体的物理化学参数，包括以摄氏度（℃）为单位的水温（T）、以微西门子每厘米（µS/cm）为单位的电导率（EC）、以毫克每升（mg/l）为单位的溶解氧（O₂），以及以mg/l为单位的主要阴离子（Cl⁻、HCO₃⁻、SO₄²⁻）与阳离子（Na⁺、K⁺、Ca²⁺、Mg²⁺）。第二个名为"Sulphur"的工作表则收录了两次采样活动的相关数据，涵盖物理化学参数、主要离子组成与稳定硫同位素值（δ³⁴S）。 本数据集具有重要学术与应用价值，其收录了2013年9月25日至2020年9月30日监测周期内采集的全部数据。这是针对该覆盖面积超2300平方公里的大型流域开展的首次大规模系统性研究成果。本数据集具备多学科应用价值，可供水文地质学家、化学家及其他相关研究人员与从业者使用，例如从事水资源管理或环境问题研究的供水机构人员。该数据集可作为优化地下水保护与防护措施、识别污染物来源的参考输入数据，同时可为卫生防护带划定工作的完善提供基础支撑。
