o:752 Tracing the nitrogen source in groundwater en Abstract: The knowledge of physico-chemical and microbiological composition of groundwater Indicates its usability and required conditioning treatments, affecting, and detennining the value and price of water. The importance of mamtaining the quality and quantity of groundwater is obvious from the fact that more than 970 0 of the total quantities of fresh water on Ealth is groundwater. Due to the slow groundwater flow, pollutants reachmg groundwater persist for a long time, requmng considerable eff01tyua nd financral investments to restore origmal water quality. In the case of nitrogen inflow in groundwater, the prevailing conditions will detennme Its fate. The aim of the research emphasizes the necessity of comprehensive research including geology, groundwater recharge regime, physico-chemical composition, to decrease uncertainties of the nitrogen Oligin determination by a smgle point of view. https://www.researchgate.net/publication/356253695_Tracing_the_Nitrogen_Source_in_Groundwater_Proceedings_SWARM_FINAL groundwater, isotopes, nitrogen 1552100 978-86-6022-367-0 1552102 https://www.researchgate.net/publication/356253695_Tracing_the_Nitrogen_Source_in_Groundwater_Proceedings_SWARM_FINAL 2022-10-11T10:34:45.562Z 44 no 46 Marija Perović Institut za vodoprivredu "Jaroslav Černi" 0000-0003-2045-001X Vesna Obradović Institut za vodoprivredu "Jaroslav Černi" person Branislava Matić Institut za vodoprivredu "Jaroslav Černi" person Dragica Vulić Institut za vodoprivredu "Jaroslav Černi" person application/pdf 330502 https://unilib.phaidrabg.rs/o:752 no yes 1 70 92000004 71A04 International Symposium Water Resources Management: New Perspectives and Innovative Practices, 23-24 September 2021, Novi Sad, Serbia 107 112 University of Novi Sad, Faculty of Faculty of Technical Sciences 2021
