The society has been marked by concern over the increasing degradation of water resources. Considering this scenario, the assessment of vulnerability of aquifers is an effective tool for methodologies of Water Resource Management. The use of these natural resources, however, still requires more conscious strategies by local actors. Any action of modifying such practices requires knowledge about the reality aiming environmental education strategies that promote changes in the behavior of the actors on the environment where they live. Based on this assumption, the general objective of this study is to map the vulnerability of groundwater in Piratini city, located in Rio Grande do Sul state, South of Brazil, situated in the Serra of Southeast, near basin of Camaquã river. It was used GOD method as the tool adapted for Brazil situations. It was ellaborated a database in the Microsoft Excel software for the 12 wells that contained all the essential information to adapt to the method of degree of confinement, aquifer environment and deepth of water level. To analyze the variables cartograms were generated from Surfer 8 program of the degree of vulnerability in the study area and in ArcGIS 10 program through the IDW method that corresponds to the interpolation between each point as a local influence, decreasing as that the distance between the points increases. In Surfer 8 software the results indicated that most of the wells shows insignificant and low vulnerability, and in ArcGIS 9.3 all wells had low vulnerability. However these results are simplified in a complex area such as the Serra of Southeast, where there are few wells due to its geology and many outcrops and springs used as human supplyDownloads

Ethical guidelines for journal publication
The REMOA is committed to ensuring ethics in publication and quality of articles.
Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.
In particular,
Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review articles should also be objective, comprehensive, and accurate accounts of the state of the art. The authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding author should ensure that there is a full consensus of all co-authors in approving the final version of the paper and its submission for publication.
Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An editor must not use unpublished information in the editor's own research without the express written consent of the author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.
Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviews should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that authors can use them for improving the paper. Any selected referee who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
