Hydrogeological and hydrogeochemical characteristics of the wider area of the regional well field Eastern Slavonia - Sikirevci

This paper establishes hydrogeological and hydrochemical characteristics of the wider area of the regional well field Eastern Slavonia - Sikirevci. The research was conducted based on the data gathered from the area of the Federation of Bosnia and Herzegovina and the Republic of Croatia. The aquifer Velika Kopanica is situated at the territory of the Republic of Croatia in the triangle between Kopanica, Gundinci and Kruševica. The river Sava partially flows through it and the aquifer extends beneath the river to the territory of the Federation of Bosnia and Herzegovina from Donji Svilaj in the west to Domaljevac in the east where its yield is the greatest. The thickness of the aquifer decreases toward the water body Odžak. It was determined that the groundwater which is drawn from wells of the wider area of the regional well field contains iron, manganese, natural ammonia and arsenic in values exceeding the maximum allowable concentration for drinking water. The increased values of these parameters are a result of reductive conditions in the aquifer. By means of a multivariate statistic cluster analysis an overview of groups of elements is provided based on geochemical affinity and/or origin
