Sažetak
A study of groundwater quality at a particular well field near Varaždin, the north-western part of Croatia is presented in this paper. Experimental date are collected for the period of 11 years and nitrate concentration annual average for each well and piezometer are calculated. The Varaždin well field is out of production for decades because of the high nitrate pollution levels in groundwater. The well field is surrounded by agricultural fields and urban area. In order to determine a spatial nitrate concentration change, eight arbitrary starting points are set and distance to each of the wells is determined. Eight directions of the nitrate pollution gradient are analysed and principal direction is detected pointing to the area where probable pollution source is to be found. The results show a decrease in nitrate concentration in the southwest-east direction at the wellfield area. The principal nitrate concentration gradient is compared to the groundwater flow direction in the area. The possible area of continuous contamination, possibly by agricultural reasons is determined as a first step to remedy this public health problem of the highest priority. © 2018, Danube Adria Association for Automation and Manufacturing, DAAAM.
