Research ArticleOpen accessIn the abstractAdsorption and Distribution of Selected High Molecular Weight Polycyclic Aromatic Hydrocarbons in a Typical Coastal Sand DepositUzoije Atulegwu Patrick, Ezenobi Chukwunoye ChristainContaminant migration study through soil medium is a veritable tool for a match towards sustainable groundwater protection. It is also essential to predict the fate and Transport of pollutants and to evaluate pollution risks. In this study, migration and distribution of High Molecular Weight (HMW) Polycyclic Aromatic Hydrocarbons (PAHs) through a coastal sand deposit of a wetland was investigated. Flow … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 27 Mar 2018 · 7,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Evaluation of the Groundwater Influence on the Stress and Strain Behavior around a Tunnel by Analytical MethodsPierpaolo OresteThe presence of an aquifer in the soil causes a change in a relevant way of the stability conditions of a tunnel. The flow of water in the pores, in fact, modifies the stress and strain state of the soil and causes an increase in the thickness of the plastic zone. As a result the loads transmitted on the lining … …American Journal of Applied Sciences, Vol. 12, Issue 10 · 30 Oct 2015 · 6,464 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Groundwater Resources of the Morainic Amphitheatre: A Case Study in PiedmontMassimo Vincenzo Civita, Marina De Maio, Adriano FiorucciProblem statement: The risk of groundwater pollution and preservation of groundwater quality of these resources are extremely important topics, particularly at the present time in which water is becoming a limitative factor for land development. In this context the main objective of this study was the evaluation of the pollution vulnerability of groundwater in the Ivrea Morainic Amphitheatre (IMA), situated … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,199 accessesView PDFCite
Research ArticleOpen accessIn the abstractPresence and Origin of Fluoride in the Complex Terminal Water of Ouargla Basin (Northern Sahara of Algeria)Imed Eddine Nezli, Samia Achour, Mohamed Djidel, Saïd AttalahProblem statement: The underground waters in the oriental regions of the Algerian Sahara, present real chemical quality problems. Their content in fluorides always exceeds the limit of the recommended levels. That is 0.8 mg L-1, according to the maximum temperature in the region. Combined to a high salinity, it affects the health of the population living around the region. The … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,677 accessesView PDFCite
Research ArticleOpen accessIn the abstractLab 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 · 6,916 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Spatial-Temporal Variability of Nitrates in a Section of the Cuneo Plain (North West Italy)Massimo Vincenzo Civita, Adriano Fiorucci, Bartolomeo VignaThe study of an aquifer system is very important, but also very complicated because of the high temporal and spatial variabilities of a system and because of the phenomena that are at play within the system. It is from these problems that the necessity arises of finding methods that are able to extend point knowledge to an entire area, while … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,733 accessesView PDFCite
Technical ReportOpen accessIn the abstractReport on the Evaluation of Ugua J2 and J3 Reservoir PerformanceOkotie Sylvester, Ikporo Bibobra, Ovuema AugustinaGlobally, there are different techniques applied in the industry such as analog, volumetric, decline curve, material balance and simulation methods to estimate hydrocarbon reserves which depends upon the volume and quality of available data with some levels of uncertainties. The analogy method is applied by comparing factors for the current fields or wells while the volumetric method implies the determination … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 7 Nov 2015 · 7,666 accessesView PDFCite
Case ReportOpen accessIn the abstractSteady State Groundwater Flow Modeling of an Ex-Landfill Site in Kuala Lumpur, MalaysiaMustapha Atta, Wan Zuhairi Wan Yaacob, Othman Bin JaafarEffective and rational management of groundwater resources require adequate information on the groundwater flow interactions with surface water and chemical species in the flow regime. The hydrologic conditions beneath the unlined ex- landfill site in Jinjang Kuala Lumpur were investigated to understand the groundwater flow and geochemical setting in which contaminants transport in the groundwater may occur in the ex-landfill. … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 30 Oct 2015 · 8,099 accessesView PDFCite
Research ArticleOpen accessIn the abstractFooting Under Static Loading: Land SubsidenceMochamad Arief Budihardjo, Su Yang, Amin Chegenizadeh, Hamid NikrazLand and footing subsidence caused by groundwater extraction is a source of many problems for buildings and infrastructures. This study aims at extending the knowledge of footing subsidence causing by ground water pumping by considering various well and load conditions. The approach is to use PLAXIS simulation to investigate the influence of well conditions on the subsidence of surface footing … …American Journal of Applied Sciences, Vol. 12, Issue 1 · 16 Mar 2015 · 7,234 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 · 7,610 accessesView PDFCite
