Groundwater was sampled at 257 locations across Serbia, including groundwater resources featuring low and high Total Dissolved Solids (TDS). The sampling network was designed to cover the entire territory of Serbia evenly and address groundwater occurrences in different rocks (igneous, metamorphic and sedimentary), and consequently different types of aquifers. The sampling points included springs, boreholes and wells. Sampling was conducted in accordance with the Drinking Water Sampling and Laboratory Analysis Rulebook (Official Gazette of the SFRY, no.

06 mg/l, which was the highest average Mg concentration among the provinces. Two groups of groundwater occurrences in the Vardar Zone can be identified: (1) groundwater occurrences with Mg concentrations up to MAC (50 mg/l), or up to the average Mg concentration for this province, generally related to limestones and influence by flysch formations, schists and Neogene sediments, and (2) 20 groundwater occurrences whose Mg concentrations were in excess of 50 mg/l, where as many as seven samples had Mg concentrations above 100 mg/l, and two samples were in excess of 300 mg/l.
