This training workshop on the theme of Interpretation and statistical analysis of environmental data was hosted at the University of Liege, Belgium, on 18/19 February 2013. The workshop was attended by 25 fellows and external participants, who included researchers, consultants and other professionals from several countries in Europe. Over the two days the participants were introduced to the principles and practice of geostatistical analysis for environmental investigations and management of contaminated sites. This included consideration of spatially and temporally variable data, with an introduction to Principal Component Analysis, Fourier Analysis and Wavelet Analysis. Computer-based exercises using MATLAB, provided the opportunity for participants to gain experience in the application of these statistical techniques for the analysis of relevant environmental datasets and use of appropriate software for intepretation. The workshop was presented by researchers from the University of Liege, University of Sheffield and Ephesia Consult, a Belgian environmental engineering consulting company.
