Implementation of European Water Framework Directive deals with integral water management policy, including the groundwater chemical and quantitative status estimation and proposal of measures for improvement of chemical and quantitative status of water bodies, which are at risk not to achieve good chemical and quantitative status till the year 2015. In the scope of Slovenian Water Management Plan, Geological Survey of Slovenia is responsible for groundwater management issues.

On the basis of the chemical and isotope analyses and tracing experiments performed, we acquired very extensive view into the hydrogeological and hydrochemical processes occurring in the both aquifers of the research area. Many new data regarding aquifer’s recharge areas, groundwater retention time, age and velocity, natural chemical composition and pollution state of groundwater were obtained. Synthesis of all the data enabled us to improve and validate the conceptual models of Ljubljansko polje and Ljubljansko Barje aquifers.

In the publication, Slovenian water resources protection system is presented. Groundwater has a prevailing share in the balance of Slovenia's water resources and in the public drinking water supply. The European Water Framework Directive (WFD) demands that the state establishes a good chemical and quantity status in all surface and ground water bodies. Three important intergranular aquifers are in the danger of not achieving the WFD demands by 2015. The current Rules on the criteria for the determination of groundwater protection areas determine four categories of water protection areas, introducing different degrees of problematic land use limitation. The article presents also supplementary measures contained in the draft of the Slovenian Water Management Plan, intended to establish a good quality status also in these heavily polluted aquifers.

An invited lecture was carried out within the seminar »Drinking Water Monitoring, inspection, and current water supply issues«, which took place on 31.10.2013 in Ljubljana. The purpose of the lecture was to enable water supply network operators to more effectively prevent the pollution of drinking water resources in different lithological types of aquifers used for water supply in Slovenia.

The article describes basic chemical properties of the KamniškoBistriško polje aquifer groundwater. The aquifer is composed of the upper aquifer in sand and gravel deposits of the Kamniška Bistrica river and of the lower, dolomite aquifer. The water of both aquifers differs significantly as to its chemical composition. Compared to the lower aquifer, the water of the upper aquifer is more mineralized and also more loaded with pollutants originating from agricultural activities. On the basis of chemical properties of groundwater from both aquifers it can be concluded that the recharge area of both aquifers is different; the upper aquifer is recharged mainly by precipitation and infiltration of the Kamniška Bistrica river, while the larger quantity of water from the lower aquifer is estimated to originate from carbonate rocks on the western fringes of the KamniškoBistriško polje.
