It is known that the active Cs sorption onto colloidal-size clay minerals in groundwater is observed and the active Cs can be transported with the colloidal fraction of groundwater by water flows. However, the longtime behavior of radioactive Cs, contained in the flowing groundwater in the aquifers of groundwater source areas, is unknown in terms of the natural water cycle. Herein, we investigate the Cs concentration in natural spring drinking water with the residence time in a groundwater source area of a mountainside composed of volcanic rock, compared with those of other trace elements. This investigation demonstrates that the observed Cs concentration in natural spring drinking water exponentially decreases slowly with the groundwater residence time (∼45yr), while several trace elements, namely, P, V, Ga, and Ge, increase in concentration with the groundwater residence time through chemical weathering. The findings suggest that CsA, contained in flowing groundwater in mountain water source areas, may decrease exponentially at the rate of one-tenth in twenty-two years, by sorption onto the aquifer through rock–water interaction excluding radioactive decay. For the sustainable management of water sources and ecosystems, the long-term (∼50yr) monitoring of the active Cs in groundwater is needed in mountain water source areas where radioactive cesium has been dispersed at times of nuclear power plant accidents.</div>","PeriodicalId":101194,"journal":{"name":"Sustainability of Water Quality and Ecology","volume":"6 ","pages":"Pages 20-30"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.swaqe.2015.04.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88006023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly, the manuscript echoes the main conclusions of a national Workshop that was held in Quito by mid 2014, about the sustainable use of water resources in Ecuador, with the purpose of proposing a research agenda adapted to the priority needs of governmental agencies. The paper discusses several key issues for the management of Ecuadorian water resources such as the urgent need for an active involvement of the national academy into the problem analysis/solving process for water management purposes, in a view of sustainable development, and as a way of warranting the effectiveness of the national policy for development oriented research that the current government is promoting. Herein, there is a need for complementing this policy by promoting a national system that foster communication between the water governmental institutions and the scientific community in terms of opportunities (financial and logistical) for scientific research in water resources and stakeholders engagement. Further, the paper stresses the urgent need of gathering and structuring all relevant knowledge/information/data into a unique repository for decision support that relies on auxiliary tools such as Geographical Information Systems (GIS), numerical modelling and associated uncertainty analyses, etc.; this in conjunction with the establishment and maintenance of a national monitoring network of water resources related environmental variables.</div>","PeriodicalId":101194,"journal":{"name":"Sustainability of Water Quality and Ecology","volume":"6 ","pages":"Pages 101-106"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.swaqe.2015.02.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83305469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first one, rainfall washes out the urban atmosphere and scavenges contaminants from aerosols, gases and thin volatile particles. The second stage refers to the catchment, in which occurs contamination due to the wash-off of particles settled on the roof’s surface as well as the scavenging of roofing materials. The third stage refers to the first-flush, storage and plumbing system. In each stage, different processes take place and add specific contaminants to the initial precipitation. Only in the third stage, after the discard of the high-polluted initial rainwater, some physical processes (sedimentation and pH increase) can also improve the quality of the rainwater harvest. With this approach, it is offered a clear view of the overall contamination processes that take place in a rainwater harvesting system.The most common microbiological and physicochemical contaminants that can be found in rainwater harvesting system were regarded, together with the eventual presence of waterborne pathogens and emerging chemical contaminants, according to an extensive review of 172 previous scientific and technical works.</div>","PeriodicalId":101194,"journal":{"name":"Sustainability of Water Quality and Ecology","volume":"6 ","pages":"Pages 119-137"},"PeriodicalIF":0.0,"publicationDate":"2015-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.swaqe.2015.04.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91763848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the presented study, we used extensive monitoring and the Soil and Water Assessment Tool (SWAT) to investigate the influence of different combinations of soil types and crop management on environmental processes (nitrogen (N) leaching and plant growth) at three study sites (Ptuj, Maribor and Dobrovce). The results show that 2/3 of leached N load from the Ptuj, Maribor and Dobrovce study sites can be expected in intervals of 51.3               year−1, respectively.
