PRINCIPLES FOR UPGRADING OF THE NATIONAL GROUNDWATER MONITORING NETWORK Abstract. Implementation of Water Framework Directive into the Polish legal acts and executive regulations, mainly by Ministry of Environment, has imposed changes into the Polish groundwater monitoring system. The leading principle of new European water policy is the protection of national groundwater resources (groundwater body – GWB). Therefore, the good chemical status and good chemical composition of groundwater in GWB require detail hydrogeological recognition of the Country. Action plans and mitigation operations referring to GWB in case of their poor chemical status should be undertaken based on groundwater monitoring data. Assessments of GWB’s status and reporting of these results to the European Commission shall be undertaken in line with guidance documents prepared by the Commission, specifically Guidance Document no 18, which requires also assessments of groundwater monitoring networks, their representativeness and statistical evaluation of the data, e.g. calculation of trend lines. New indicators of groundwater pollution, as pesticides, PCB and organic compounds have been introduced into assessments and these demands defining new analytical methods that will be precise and relatively cheap. Besides the chemical laboratory methods, new methods of in situ examinations, sampling procedures and construction of observation points should be implemented. New goals of groundwater monitoring are arise from other EU directives, as “nitrate”, “flood” and INSPIRE directive. The last one, implemented at present, mainly refers to the gathering of monitoring results, storing the data in the data bank and affords possibilities of data exchange among the EU member countries. It is especially substantial in case of transboundary aquifers.
