Among them, sorption by Fe(III) oxide/hydroxides was found to be one of the dominant processes retaining As in the aquifer matrix. Managed Aquifer Rehabilitation (MAR) by enhancing Fe(II) oxidation to promote As sorption was proposed and tested in a pilot-scale field experiment. Periodical injection of Fe(II) and ClO<sup>−</sup> into a high As sandy aquifer triggered formation of new Fe(III) (hydr)oxides coating on sediment particles via advanced heterogeneous oxidation of Fe(II) and concurrent oxidative adsorption of As(III) via co-precipitation and surface complexation with Fe(III) (hydr)oxides. Monitoring results indicate that aqueous As concentration decreased from the initial average value of 78.0μg/L to 9.8μg/L over the 25-day amendment period and leveled off below 10μg/L for the following 30 days. MAR is thus proved to be a cost-effective approach for remediating high As aquifers.</p></div>","PeriodicalId":101039,"journal":{"name":"Procedia Earth and Planetary Science","volume":"17 ","pages":"Pages 13-16"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeps.2016.12.009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81709821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Owing to the rapid industrialization and urbanization of this city, more water resources are necessary in this semi-arid region. Thus, the objectives of this work were to characterize the chemical properties of groundwater supplied to MMA and to assess inter-annual variations in the water chemistry. Three groups of water were identified: recharge waters from mountain belts dominated by marine sedimentary rocks (Ca-HCO<sub>3</sub> type), transition zone waters from alluvial sediments (Ca-HCO<sub>3</sub>-SO<sub>4</sub> type) and waters flowing through conglomerates and alluvial sediments of the northeastern MMA (Ca-SO<sub>4</sub> type). The ionic composition and the salinity gradient of each water group were in agreement with the topographic flow paths of the study area. The non-parametric Mann-Whitney U-test indicated that there have been no significant changes on the groundwater quality supplied to the MMA between the years 2006 and 2012.</p></div>","PeriodicalId":101039,"journal":{"name":"Procedia Earth and Planetary Science","volume":"17 ","pages":"Pages 356-359"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeps.2016.12.090","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84245279","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During this time, water–rock interaction on surface as well as in the rock around the repository will progress. All exogenous processes will depend on future evolution of climate. Based on the research of Quaternary sediments, three limiting scenarios of future climate evolution are considered: Maximum cooling and drying in glacial periods; maximum warming and moistening in interglacial periods and climate evolution affected by elevated concentrations of CO<sub>2</sub> in the atmosphere. Formation of permafrost, infiltration of melted water and oxidation will influence chemical composition of ground water. Two analogues of the changes are presented. They are ground waters in two mines in the Bohemian massive: (1) Mine “Svornost” in an abandoned historical uranium deposit Jáchymov (Joachimstahl), (2) underground research facility of “Bukov” near the uranium deposit of Rožná. Ground water was sampled from surface to a depth of 1200 m. The water–rock interaction during the infiltration and flow of ground water is the cause of the observed stratification of the chemical composition. The chemical composition of the collected samples indicate a probable future composition of ground water within the repository.</p></div>","PeriodicalId":101039,"journal":{"name":"Procedia Earth and Planetary Science","volume":"17 ","pages":"Pages 100-103"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeps.2016.12.013","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80905644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
