Abstract: The contents of nitrates and nitrites were monitored in
15 ground water resources of a selected region earmarked for the
emergency supply of population. The resources have been selected on
the basis of previous assessment of natural conditions and the
exploitation of territory in the infiltration area as well as the
surroundings of water resources. The health risk analysis carried out
in relation to nitrates and nitrites, which were found to be the most
serious water contaminants, proved, that 14 resources met the health
standards in relation to the assessed criterion and could be included in
crisis plans. Water quality of ground resources may be assessed in the
same way with regard to other contaminants.
