Quality status assessment of groundwater in the wider area of Zadar

U cijelom svijetu najvažniji resurs za opstanak života je pitka voda. Postoje razni negativni utjecaji koji narušavaju nenju kvalitetu. Krški teren zauzima više od polovine teritorija Hrvatske, karakterezira ga bogatstvo vode izuzetno visoke kvalitete, no blizina Jadranskog mora ima znatno negativan utjecaj. Prodor slane morske vode u krške vodonosnike predstavlja ozbiljan problem, posebno tijekom ljetnih sušnih razdoblja. Za zaštitu krških vodnih resursa potrebna su specifična znanja kojima se približava problematika istraživačima, ali i samim korisnicima. U ovom radu prikazano je stanje kakvoće podzemne vode na području tijela podzemne vode Bokanjac - Poličnik. Uvodni dio definira problematiku promatranog područja, vodne objekte u slivu, geološke, te hidrogeološke značajke. Zatim su prikazani podaci o kemijskom stanju na temelju kojih su napravljeni razni testovi i analize. Za rješavanje problema predložene su mjere za potencijalno spriječavanje problema.The most important resource for survival in the whole world is water. There are many negative impacts that contribute to water quality impairment. Karst terrain occupies more than a half of the Croatian territory and it is characterized by the richness of exceptionally high quality water, but the vicinity of the Adriatic Sea has a considerably negative impact on the water. Breakthrough of salty sea water into karst aquifers is a serious problem, especially during dry summer periods. In order to protect karst water resources, specific sets of knowledge are needed to bring the matter closer both to researchers and to users themselves. In this paper it has been shown the state of groundwater quality in the area of Bokanjac – Poličnik groundwater body. The introductory part defines the problems of the observed area, water facilities in the basin, and geological and hydrological characteristics. Afterwards, the data on the chemical state of groundwater, which was the basis for various tests and analyses, has been presented. In order to solve the problem, measures for potential problem prevention have been proposed
