This presents an analysis of modeling the deposition of nitrogen compounds fed to the surface area of water intake on the water quality intake "Grotowice" near Opole. The analysis carried out of land use allowed for the identification of major risk factors for water quality. Based on studies was estimated factors which may constitute the greatest threat to groundwater. Based on the conducted analysis, conclusions for further research were formulated.

This article analyzes the impact of land surrounding the area of water intake on the state of water quality intake "Grotowice" near Opole. The analysis of land development allowed for the identification of major risk factors for water quality. Estimated factors which may constitute the greatest threat to groundwater. Despite the fact that the analysis of water quality intake shows a positive and lasting trend decrease in the content of nitrogen pollution since 2008, the problem of contamination by nitrogenous compounds for the analyzed intake is still current. On the basis of the data presented in the article stated a direct impact on the state of spatial quality intake. Based on the conducted analysis, conclusions were formulated for further research.

The following article analyzes water quality in “Grotowice” water intake, especially in terms of the presence of nitrates. The analysis of changes in nitrates levels in the period from 2000 to 2012 has shown a positive and lasting trend of decreasing of their content since 2004. Nevertheless, the problem of contamination with nitrogenous compounds for the analyzed site is still valid. The most important of them is the need for a buffer zone for each intake well.
