Résumé

Data quality within the framework of environmental monitoring programs is a major issue for reliable decision-making. Intercomparison is a very useful quality control tool but is rarely available for sampling operations, especially for groundwater. This intercomparison trial on groundwater sampling has been organized by BRGM as part of Aquaref (French Reference Laboratory) programs. The aim was to assess the impact of the practices of 10 sampling teams on the monitoring results of around 120 parameters on a given groundwater-sampling site. Compared to a similar trial organized in 2009, this trial focused mainly on the risks of contamination on “emerging” pollutants results. Moreover, the trial addressed qualitative (sampling practices) and quantitative (dispersion of results) evaluation.
