Quantification of the Impact of Nitrates on Underground Water Quality by Using Raps Method- Example of the Well Field Bartolovec near Varaždin in Croatia

Nitrates have their presence in underground water in natural form or from anthropogenic sources. Anthropogenic impact includes human activities in form of the fertilizers and pesticides, which have a negative impact on human health. The main problem with nitrates is their presence in underground water, when this water is used as drinking water for settlements and cities. The main goal of all research connected with the mentioned problem is to find, determine, and quantify potential sources of the nitrates, and after this to connect natural and anthropogenic factors which contribute to the rising the nitrate amount in the underground water. Such a task means lots of fieldwork and laboratory measurements. There is a plan to show methodology for contributing to solving issues of nitrate in groundwater for the case study of the well field Bartolovec, which is the primary underground drinking water source for Varaždin County and the city of Varaždin in Croatia. In the first step, the time series of the nitrates will be shown and statistically analyzed on a yearly and monthly basis. The second step is to provide further statistical analysis on a higher level by the application of the Rescaled Adjusted Partial Sums (RAPS).
