SUMMARY

The water problem in Argentina has been considered by a series of different analyses and reports as the greatest environmental conflict in the country. The case of the Municipality of Junín, in the Province of Buenos Aires, can be deemed a prototype as it involves several questions due to problems related to pollution, non-potable water, floods, as well as demand for access to this resource.  This project elaborated a multi-phase and multi-disciplinary diagnosis of this issue in the Municipality of Junín.  It can be perceived as the first input in terms of the integrated management of this resource, in order to encourage participatory projects to determine multiple use programmes for a natural resource shared by different social actors.  The work consisted of a brief characterization of the region and its problems, followed by a presentation of studies on water quality undertaken by the Municipality and then studies on opinion and perception on water issues.  Finally, this work concludes with a legal and administrative analysis of the issue.

General description of Junín

 Junín is a medium-sized department located in the Pampa area of the Province of Buenos Aires, Argentina.  It holds the largest human settlement in that region.  This municipality, apart from the urban area and its small and medium-sized industrial activities, algo conducts relevant agricultural and cattle breeding activities.  From the ecological standpoint it is an area with key characteristics for large scale agriculture, the so called Pampa Ondulada Alta of the wet pampa.  The district of Junín has about 85.000 inhabitants.

Water quality studies at the Municipality of Junín

The objective of this part of the study was to conduct a diagnosis on the quality of potable water provided to the city of Junín.  The water provided to this city is ground water and the service comprises 22 wells that feed into the distribution network; some operate directly and others through distribution tanks and storage tanks.  For this reason, the contribution of each point of the network will include a combination of different water proportions coming from such wells.

Regarding its physical-chemical composition, the piped water of the Junín city  has a medium mineralization level.  Regarding the different physical and chemical parametres defined in the case of potable water according to our legislation, and as a result of data revealed by this work, there are certain traits that can be objected such as insufficient concentration of free residual chlorine and the high levels of arsenic, fluorine and nitrates.  It follows, therefore, that this is non potable water. 

Social aspects and perception on water issues in Junín 

The different methodologies used to measure social perception on water, point to the fact that the civil society clearly identifies the problems.  Among other results, we may point out that 86% answered in the affirmative to questions in this regard.  11% indicated that the issue is not a source of concern.  Floods are perceived as the most critical problem, as indicated by 79% of the answers.  Pollution of water sources is the second problem perceived by 64% of answers while 57% indicated that the lack of potable water supply was a difficulty they experienced in Junín.

Several other conflicts were identified in Junín in relation to the use of water.  To summarize, we can say that civil society in Junín has key claims in relation to water as a resource, explicit claims and subliminal claims.  Several conflictive situations are identified as the use in the region is multiple and even potentially conflictive depending on the application.  Conflicts arise between those who pollute the resource and those who use it, between those affected by floods and institutions in charge of alleviating the impact, and between those who have no access to water networks and the institutions in charge of supplying water.   The degradation of water quality imposes limitations in the use of the resource as well as potential new conflict among users with rights over this resource.

Legal and administrative analysis

The third part of the project consited of a detailed and comprehensive analysis of legal and administrative aspects related to the waters in the municipal territory of the Province of Buenos Aires; specifically in relation to the Municipality of Junín. It started with a survey and study on the current legislation at the national, provincial and municipal levels.  In consequence, an intricate water control and management system is observed, both at the national and provincial scales.  This kind of division, added to the weakness of provincial and/or municipal control institutions, leads to a waste of efforts in law enforcement and adds to the existing complexity.  In this regard, in the Province of Buenos Aires one may say there is a thorough but complex legislation and its relation to the national legislation may lead to varied interpretations.

 Public bodies created for the enforcement of legislation have neither management capacity nor political-administrative relevance to guide social activities in accordance with the aims set forth by the environmental regulations.  The lack of demand on the part of stakeholders, the administrative overlaps and the difficulty of perceiving the environmental aspect during trials and other legal activities, constitute some of the reasons why there are no criteria for legal interpretation and the broad legal debate with tangible social repercussions is not encouraged.  Punishment, economic charges, fines, taxes, etc., in some cases may be insignificant or will not preclude action and are not enough to repair damages.  Furthermore, even though the issue seems complex and varied there are no coordinating bodies to facilitate the implementation of shared policies.
