1. 1. Evaluation of stimulated reductivedechlorination in situ of chlorinatedsolvents at a site in Huddinge : using principal component analysis, partialleast square regression and degradation

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Karin Ljungberg; [2018]
   Keywords : Reductive dechlorination; DNAPL; stimulated bioremediation; chlorinated solvents; Reduktiv deklorering; DNAPLS; stimulerad biologisk behandling; klorerade lösningsmedel;

   Abstract : The method of using stimulated reductive dechlorination when remediating sites contaminated with chlorinated solvents is not unusual, but not many studies have been done on the overall process outside of a controlled environment. In order to investigate the process, principal component analysis (PCA) and partial least square (PLS) regression was used to identify the most important parameters for the degradation of the chlorinated solvents.

3. 2. Iron material for the remediation of DNAPL-polluted groundwater

   University essay from KTH/Mark- och vattenteknik

   Author : Jens Rodenhäuser; [2003]
   Keywords : chlorinated ethylene; iron; reductive dechlorination; groundwater; batch experiments; column experiment; ;

   Abstract : Tetrachloroethylene and its daughter-products represent a group of contaminations which are frequently found at sites with industrial activities, such as metal processing, electrotechnical and pharmaceutical industries as well as dry cleaning of clothing and the production of colours, paints and laquers. Due to their toxicity and persistence under natural conditions "denser-than-water" non aqueous phase liquids are substantial threats to the subsurface environment as well as the surface ecosystems including human beings.
