Samples of long term exploited geothermal waters sometimes show that composition of water has been changed during the exploitation. Those changes can be caused by neglecting appropriate standards application during of sampling or other factors such as: chemical and biological nature of the samples, their temperature, exposure to light, sort of container used, time between sampling and a chemical analysis and overall conditions during transport (ISO 5667-3:2012). The European Union directive (DT 2009) indicates necessity of implementation of the quality assurance and quality control (QA/QC) program related to water monitoring. According to ISO 5667-1:2006 there is no universal QA/QC program, which could be used for all purposes. Therefore, it is very important to develop an individual field QA/QC program for each research, which will be optimum for a particular purpose of a research. ISO 5667-14:2004 standard precisely describes techniques used for quality assurance purposes: – in order to determine precision of sampling, it assumes collecting duplicate samples, – in order to monitor samples contamination, it assumes analysis of field blank samples, – in order to determine sample stability during transport and storage, it assumes analysis of spiked samples – samples with the addition of analyte. Objective of our work was to design the QA/ QC program for geothermal waters from PG-P1 and PG-P3 wells in Bańska Niżna exploited by Geotermia Podhalańska Company. It will supplement to the ongoing research. It will involve collection of control samples (duplicate, field blank and spiked), which allows establishing reliability of obtained results of physico-chemical analysis. Designed program is also a part of extensive monitoring, which will be used to determine the changes of water chemical composition in a given time and to compare them with results from previous monitoring series.
