A. MUNTEAN, M. COMAN
ABSTRACT. - In the west part of Baia Mare - the residence of Maramureş county, nearby from the triad of the mining tailings dumps – Săsar, Aurul and Remin, practicing an subsistence agriculture, on land subjected to anthropogenic impact for decades. Furthermore, these lands are crossed by pipelines of the hydro-transport of the flotation tailings from the preparation plants to the tailing ponds. In this area, very long time exploited, the quality of groundwater of course, is affected. The monitoring of the nitrogen regime of these waters, was induced by the implementation of an agricultural research, on an experimental plot, located near the tailing ponds. This paper refers to the nitrogen regime of groundwater from two wells, located upstream and downstream from the agricultural experimental plot.
Keywords: nitrogen regim, groundwater, tailing pond, agriculture.
