Adequate level of natural ground water resources, their better quality, lower costs for their treatment, and potentially lower risk of contamination make ground water the dominant drinking water source in Slovakia.
In line with the data drawn from the water management balance, natural ground water resources in Slovakia represent the average value of 146.7 m3.s-1. Of this volume, documented usable ground water sources in Slovakia take up 78 945 l.s-1, i.e. more than 53.81 % from natural sources.
Due to the fact that the volume of abstracted ground water in Slovakia has been decreasing since 2005, intensity of ground water exploitation has also been decreasing, since 2010, intensity of ground water exploitation has remained approximately at the level of 13.8 %. In terms of documented usable sources of ground water in Slovakia, we can say that both, most recent and anticipated water demand have been satisfied also despite the fact that distribution of high-quality water sources within individual regions has not been quite uniform. Approximately one half of them are located in the southwest of Slovakia, especially in the area of Žitný ostrov. On the other hand, regions of the middle and eastern part of the country suffer from the lack of usable water sources and may suffer from the lack of drinking water in the future.
The OECD Green Growth database contains selected indicators for monitoring progress towards green growth to support policy making and inform the public at large. The database provides a synthesis of data and indicators available across a wide range of domains. The sources of the underlying data used to populate the Green Growth Indicators, as presented here, include a range of OECD databases and, in some cases, external data sources. The database covers OECD member countries, accession countries and selected non-OECD countries (including the BRIICS economies - Brazil, Russian Federation, India, Indonesia, China and South Africa).
Selection and methodology of indicator’s assessment is based on the set of indicators proposed by the OECD and addressed by the report: "Green Growth: Monitoring progress towards green growth“. Data relating to the national situation are usually presented in the period between 2000 and 2012. Basic time sequence is changed in those cases when the data are not accessible or when their comparison is not possible due to differing approaches in their collection, assessment, changes in methodology, classification, etc. Summary assessment of indicator’s trend from the green growth perspective is based on a subjective evaluation of the responsible assessor due to the fact that the strategy is not officially implemented in the Slovak Republic and therefore specific objectives have not been defined. Naturally, this assessment builds on the analysis of the past trends, as well as their anticipated direction in view of the measures adopted as to date.
Selected indicators characterize Slovakia's initial position as seen from the perspective of the green growth and were to be used as a measuring tool before further steps are taken in the process of implementation of this strategy and for a complex assessment of the future trend of the Slovak economy. Present set of green growth indicators comprises 32 individual indicators that are relevant in Slovakia's conditions. Four of them are national indicators that describe voluntary instruments of the environmental strategy.
Data used in this document come from the official national or international sources and databases. Assessed trend was reviewed and discussed with the state administration specialists (individual departments of the ministries of Environment, Economy, Labour and Social Affairs and Family, Finance, Agriculture and Rural Development) and their professional organisations (Slovak Hydrometeorological Institute, State Geological Institute of Dionýz Štúr, Slovak Environmnet Agency, State Nature Consservancy, Institute for Financial Policy) and also the Statistical Office of the Slovak Republic whose databases furnish most of the information.
