Research ArticleOpen accessIn the keywordsEvaluation of Hydrogen/Oxygen Release Compounds for the Remediation of VOCsS. Fiore, M.C. ZanettiProblem statement: Volatile Organic Compounds (VOCs) were widespread in groundwater of industrialized areas and in situ remediation intervents characterized by a high environmental compatibility were of main interest. The scope of this study was the evaluation of the potential of two innovative reagents (HRC and ORC from Regenesis) for the remediation of Volatile Organic Compounds (VOCs). The reagents respectively perform … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 4 Nov 2011 · 7,439 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPreliminary Tests Concerning Zero-Valent Iron Efficiency in Inorganic Pollutants RemediationSilvia Fiore, Maria Chiara ZanettiProblem statement: This study was aimed to a preliminary evaluation of the applicability of granular Zero-Valent Iron (ZVI) to the on site remediation of groundwater polluted by inorganic contaminants by means of a Permeable Reactive Barrier (PRB). A particular interest was devoted to groundwater impacted by Acid Mine Drainage (AMD) that was caused by the oxidation of metal sulphide minerals … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 6,789 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLab Tests for the Remediation of a PCE Polluted Site by Means of HRC ReactantMaria Chiara Zanetti, Silvia FioreThe injection of reactants is a remediation technology that may be applied both in the vadose zone and in groundwater. In this work a new reagent is examined for the remediation of the vadose zone and groundwater of an industrial site polluted by perchloroethylene (PCE). The tested reactant is the HRC (Hydrogen Release Compound, Regenesis, USA), a reducing agent which … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Permeable Reactive Barriers to Remediate Heavy Metal-Contaminated Groundwater through a Laboratory Column ExperimentSomean Yin, Gemunu Herath, Sokchhay Heng, Senajith KalpageRecently, groundwater sources are being polluted by various activities such as agriculture, livestock, decentralized wastewater treatment systems and acid rain. Groundwater can also be polluted by landfill leachate, sewage, mine tailings, non-engineered deep well disposal of liquid waste and seepage from industrial waste lagoons. There are many studies reported contaminated groundwater remediation using Permeable Reactive Barrier systems (PRBs) and many … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Mar 2017 · 8,761 accessesView PDFCite
Research ArticleOpen accessIn the abstractIndustrial Waste-an Economical Approach for Adsorption of Heavy Metals from Ground WaterMargherita Pettinato, Debolina Mukherjee, Silvestro Andreoli et al.A by product from steel industry mainly known as blast furnace slag is a waste product which was tested for the removal of As(III), from ground water. Steel slag is a commercial waste material mainly consisting of SiO2, Al2O3 and CaO, the former two chemicals being major components of zeolites and the latter a major component of Hydroxyapatite (HAP). Arsenic … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 10 Apr 2015 · 8,155 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOUPLED NITROGEN AND OXYGEN ISOTOPE STUDY OF NITRATE AT A RURAL UNLINED LANDFILL IN WESTERN VICTORIA, AUSTRALIAJohn W. Moreau, Andrew M. MinardUnderstanding of site-scale physical and chemical heterogeneities will inform remediation strategies for unlined rural landfills worldwide. The aim of this study was to characterize potential sources of nitrogen contamination to groundwater at an unlined landfill in rural western Victoria, Australia. Results revealed simultaneously high concentrations of both nitrate and ammonia within several wells, indicative of heterogeneous redox potentials within the … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 30 Jun 2014 · 7,607 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Earthquake Demolition Debris on the Quality of GroundwaterM. S. Benmenni, K. BenrachediProblem statement: Debris from construction or demolition/deconstruction processes have no significant impact on the environment as they are res-usable and inert. This has been also long admitted for solid waste generated by the demolition of damaged cities following violent earthquakes. Approach: This study is a contribution to the assessment of actual impact on the quality of groundwater of buried demolition … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,236 accessesView PDFCite
Research ArticleOpen accessIn the abstractMNM1D: A Numerical Code for Colloid Transport in Porous Media: Implementation and ValidationTiziana Tosco, Rajandrea SethiProblem statement: Understanding the mechanisms that control the transport and fate of colloidal particles in subsurface environments is a crucial issue faced by several researchers in the last years. In many cases, natural colloids have been shown to play a major role in the spreading of strongly sorbing contaminants, while manufactured micro-and nanoparticles, which are nowadays widely spread in the … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 8,291 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordClamshell vs. Backhoe Excavation of Permeable Reactive BarriersRajandrea Sethi, Steve Day, Antonio Di MolfettaProblem statement: Permeable Reactive Barriers (PRBs) were one of the most widespread solutions for the remediation of contaminated aquifers. Although, a variety of excavation methods had been developed, backhoe (hydraulic excavators) were commonly used for the construction of PRBs in North America. Approach: In Europe, the most common method of slurry excavation was with a hydraulic grab and crane. The … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 4 Nov 2011 · 7,238 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPerformance Assessment and Monitoring of a Permeable Reactive Barrier for the Remediation of a Contaminated SiteValerio Zolla, Rajandrea Sethi, Antonio Di MolfettaThe present study illustrates the long-term monitoring plan carried out in order to investigate the performance of a zero-valent iron permeable reactive barrier (PRB) at a chlorinated solvents’ site. The cleanup intervention has been undertaken at an industrial landfill located near the city of Turin (Italy) and represents the first full-scale application of this technology in Italy. The monitoring plan … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,438 accessesView PDFCite
