Rural areas from Romania are still characterized by poor access to quality water and sanitation. The study addresses the drink water physical-chemical quality of private wells in Iara Commune, Cluj County. Water samples from 6 individual wells in Iara Commune as well one sample of water from groundwater abstraction source, were analysed with the main purpose of determining the following compounds and quality indicators: pH, conductivity, permanganate index, dissolved ions, metals, and the results were compared with the limits allowed by the legislation in force. The results, regarding the physical-chemical indicators measured, generally showed a good quality of underground water resources, except for nitrate content in several samples, revealing risks due to the presence of local polluting sources, or possible poor wells exploitation and maintenance practices

The deterioration of the marine environment has become evident all over the world and European waters are noexception. Therefore in the last few years the European Union has been engaged in an effort to develop a marinestrategy to protect the marine environment and a more encompassing integrated maritime policy that would provide acomprehensive system for the management of the uses of the marine areas of Europe. The EU Marine StrategyFramework Directive (2008/56/EG, MSFD) provides a regulatory framework for the management of the impacts of avariety of human activities on the EU's marine waters. The MSFD introduces the notion of "good environmental statusâ€ronment and constitutes a framework for the sustainable use of the marine environment in order to ensure its continueduse by current and future generations. The effective protection of the marine resource base is indeed a precondition forachieving sustainable wealth and generating employment, at a time when the EU is seeking to reinvigorate its economy.It will also enhance the quality of life in the European Union.

Economic reasons and environmental concerns led since 2005 to a substantial decrease of the mining activities for complex minerals in Romania. Valea Vinului mining area, located in the National Park Rodnei Mountains was subjected, as the majority of mining operations in Romania, to closure and conservation programs. Although, since 2007 mining activities ceased in this area, and measures to contain the pollution were applied, acid mine drainage (AMD) still remains a problem, contributing to the deterioration of the surface water quality. The study was focused on assessing the impacts of the collected and treated mine waters, on the chemical quality of Valea Bailor River, tributary of Somes Mare River. The results of the analyses were revealed based on the variation of the main mine waters indicators, namely, the water quality was characterized on the basis of the Fe, Pb, Zn and Cu contents and on the basis of the pH and electrical conductivity. For interpretation, the obtained values were related to the limits imposed by the Romanian Legislation.
