Transboundary and Not-Tranboundary Aquifers in the Basin

Transcription

1 Second Assessment of Transboundary Rivers, Lakes and Groundwaters under the UNECE Water Convention Transboundary and Not-Tranboundary Aquifers in the Basin Slovak Hydrometeorological Institute Bratislava, Slovakia

2 Groundwaters are the main source of drinking water and they underlie the economic development degree and living standard in the Slovak republic. Slovak republic belong to the states with expressive orientation of water system on groundwaters. Groundwater is the drinking water source of the highest quality. Both, groundwater (82.2 %) and surface water (17.8 %) are exploited as drinking water in Slovakia. Žitný ostrov is the biggest natural groundwater source in Slovakia and in Central Europe with app l.s-1 capacity.

3 The basic precondition of groundwater state assessment is definition the groundwater body. characterise the water, assessment water state, comparison with the environmental aims

4 DEFINITION GWB in according the Regulation about water every GWB representatives definable capacity in aquifer it was necessary to defined all GWB in which extraction amounts are more than 10 m 3 /day (0.116 l.s -1 ) or which supply with drinking water (> 50 persons) definition of GWB as transboundary GWB is incorporated to the river basin GWB were defined according geological and hydrogeological conditions and according the hydraulic boundary GWB were defined according to qualitative aspect of GW and according to significant differences in quality of GW

5 GWB we defined in 3 individual layers: a) GWB of Quaternary sediments b) GWB of pre-quaternary rocks c) Geothermal waters (deep circulation of groundwater with temperature over 15 C)

34 Groundwater quality VAH chemical status of GWB SK200270KF and POPRAD chemical status of GWB SK200440KF has been assessed as good IPOLY - In groundwater body SK P increased content of total iron and manganese in groundwater is generated from geogenic sources. - According to groundwater chemical status assessment (2007) in 64% area of groundwater body SK P concentrations of nitrates and in 36% area concentrations of ammonia ions exceeded threshold values. Exceeded concentration of atrazine in eastern part of groundwater body has local character. - Chemical status of groundwater body SK P has been assessed as bad due to contents of ammonia ions, nitrates and sulphates.
