Improving the national monitoring of groundwater chemical status by applying the Ru index

Two complementary proposals were given to improve the national monitoring of groundwater chemical status in the grouped groundwater body "Eastern Slavonia - Sava River Basin". The aim of this research was to ensure an even distribution of monitoring stations in the study area and systematic monitoring of groundwater quality in deeper parts of the aquifer system. This is important as the national monitoring stations are used to assess the status of a grouped groundwater body according to the methodology in accordance with the provisions of the Water Framework Directive as well as the Groundwater Directive. Based on hydrogeological and geological characteristics of the investigated area, an objective assessment of the representativeness of the monitoring stations, using the RU index, was done. Representativity Index (RU index) is used to measure monitoring network homogeneity expressed in percentages. The first proposal of improvement of the national monitoring of groundwater chemical status includes 11 monitoring stations, with a RU index of 80.10%, two of which, as new observation wells, should be drilled at shallow depth of the aquifer system. Seven observation wells and two pumping wells around Gunja and Đakovo are part of the existing national monitoring system. The second proposal complements the first one and includes 17 monitoring stations, with a Ru index of 82.48%, six of which, as new observation wells, should be drilled at a greater depth of the aquifer system. These proposals would enable better confidence of groundwater chemical status and trend assessment, as well as more reliable determination of ambient background values of groundwater quality parameters. Implementing these proposals in practice and getting insight into new hydrogeochemical data from the deeper part of the aquifer system would give the possibility of delineating the grouped groundwater body "Eastern Slavonia – Sava River Basin" by depth into two new groundwater bodies, the shallower and deeper.
