Abstract
Pollutant limit values are used in the procedures of chemical status assessment of groundwater bodies and risk assessment of failure to achieve environmental objectives for groundwater. The paper elaborates in detail the legal basis for determining limit values according to EU directives and presents the guidelines for determining limit values from the relevant CIS guidance documents resulting from the Common Implementation Strategy for the Water Framework Directive (2000/60/EC). Scientific aspects of the approach to determining limit values were based on the application of the environmental criterion (environmental protection) and use criterion (protection of drinking water and other legitimate water uses). A possibility to implement suitable numerical indicators of dilution and pollutant breakdown impacts, as well as the importance and methods for determining ambient background concentrations of substances in groundwater were analysed. The paper also presents the results of comparative analyses of the implementation and comparability of methodologies for determining limit values in EU Member States, which was conducted during 2012 and 2015.
