Migration of pollutants in a saturated aquifer. A theoretical and experimental approach

Technical Report:

Abstract

The report describes the testing of experimental methodology at the Reactor laboratory of the Technical Research Centre of Finland (VTT), for studying the water transport of e.g. pollutants in geological media. The methodology tested includes an experimental transportation migration box, automatic sampling, and HPLC-IC system. The systems testing was done using a migration box containing quartz sand through which the water flowed horizontally. At the beginning of each test inorganic or organic compounds were rapidly mixed with influent water. Samples were taken continuously from various sampling points in the sand and analyzed with the HPLC-IC technique. The results are presented in temporal concentration curves for each one of the species studied. Three tests were made in order to study the retention of inorganic anions and cations and some organic compounds. It was also found that the retention factors increase somewhat with increasing migration distance which is explained by dilution of the chemical pulse during its transportation through the aquifer. The present work shows that the methodology can successfully be used in the study of the transport of chemicals in porous geological media. The methodology is likely to be applicable also to other types of geological systems although this was not  More>>
