Bardo - Opis:
- Quality of groundwater is the most important issue in water management, especially in matter of using groundwater for local community consumption. Assessment of quality of the resources of groundwater is based on the results of chemical status monitoring and both are carried out according to EU regulations: the Water Framework Directive (2000/60/EC), the Groundwater Directive (2006/118/EC) and the Directive 2009/90/EC, and also national regulation (Regulations of the Minister of the Environment, 2008 and 2011). This paper presents the quality classification and groundwater chemical status assessment in part of catchment area of the Nysa Kłodzka river near Bardo town. Qualification and assessment was based on results of the field hydrogeological investigations and the chemical analysis of composition of the groundwater samples from monitoring points. In research area the major group are the groundwater rating as IV-class quality (62%). There are 23% of groundwater with II and III-class quality status and in the V-class – 15%. There are no points with groundwater rating as I-class quality. In area configuration groundwater in the part of Nysa Kłodzka river catchment are qualified as IV-class, so the chemical status is rating as poor. Assessment was accomplished by arithmetic average. Poor chemical status is caused by elevated concentration of selenium (Se), arsenic (As) and nickel (Ni). Occurring of this elements in groundwater is probably natural, because of geological structure of research area and lithology of aquifer.
