Sulfur balance of ground water in selected industrial sites, Berlin / Bilanzierung der Schwefelbelastung im Grundwasser an einem ausgewaehlten Industriestandort, Berlin

The Federal Institute for Materials Research and Testing (BAM) was commissioned by the Senate Department of Urban Development, Berlin, to carry out the investigations regarding the mass balance of the sulphur containing components of three selected groundwater samples from an industrial contaminated site in Berlin. The soil and groundwater contamination was caused by chemical waste of the former industrial site. The information on content of different organically bound sulphur compounds, colloidal sulphur and dissolved sulphides is of great importance for the layout and dimensioning of groundwater cleaning plants (active carbon, catalyst). It was therefore decided to carry out investigations in order to be able to estimate the mass balance of sulphur content of ground water from three different sampling points, which represent the typical specific contamination prior to the process of calling tender for the cleaning of groundwater. Within the frame of this investigation - both the group parameters as total sulphur content, purgeable and adsorbable organically bound sulphur (POS, AOS) and extractable high and semi-volatile organic sulphur compounds as well as the main organic individual sulphur contaminants are to be determined after identification with GC-MS and GC-AED. Our approach for the estimation of sulphur mass balance together with the applied procedures and methods are described in this report. The results achieved are then discussed, compared, evaluated and checked for plausibility and correctness.
