Short description: Holland Milieutechniek and Bioclear (www.bioclear.nl) published a scientific article on Wiley InterScience® (www.interscience.wiley.com) about a successful ElectroBio Reclamation (heating of VOC) project in Zeist (The Netherlands). Wiley InterScience is a leading international resource for quality content promoting discovery across the spectrum of scientific, technical, medical and professional endeavours. 
Long description: A residential area that was formerly part of a silver factory site severely contaminated with chlorinated solvents was remediated using an in situ electro-bioreclamation technique. Electro-bioreclamation is a method for heating soil and groundwater combined with soil vapor and low-yield groundwater extraction and enhanced reductive dechlorination (ERD). During the first two years of remediation in the source area (the intensive phase), a total of 80 kg of volatile organic compounds (VOCs) was removed by heating combined with ERD. After another two years of ERD in the source and plume areas (the attenuation phase), the VOC concentrations were reduced to a level below 100 µg/L in groundwater. Given these satisfying results, electro-reclamation in combination with ERD turned out to be a successful in situ remediation technique for removing VOCs.
