Different from drinking water supplied by the municipal network or from other bottled waters, all of which undergo some kind of prior treatment in order to become potable, the natural mineral water is an ecologically pure product, that by virtue of its composition may induce beneficial health effects. According to the EC Directive 80/777, the main criteria used for defining the natural mineral water refer to its original purity and its adequate protection against any pollution hazard. In Romania, mineral water consumption is an old tradition. The geological setting and the existence of unpolluted areas favored the development of mineral water sources of an outstanding quality, many of which include also carbon dioxide in natural state. The present work presents the main sources of bottled mineral water in Romania, classified as a function of total mineral content, ionic composition and carbon dioxide content. There are also forwarded forecasts concerning the medium term evolution of the structure of the bottled mineral water market in Romania.  相似文献

Turkey lies on the Alpine-Himalayan belt which is one of the most important geothermal belts in the World. Therefore, there are numerous mineral waters in Anatolia where geological and tectonic activities are intense. Archeological studies conducted in Anatolia, which is the cradle of various civilizations, reveal the fact that mineral water has been used as a spa in many areas.The scope of this study is to evaluate mineral waters in Western Anatolia and their use in thermal resorts for balneological purposes. In this respect, 50 thermal waters used in spa centers were analyzed for various physical, chemical and bacteriological parameters.Among the 50 waters tested, 40 are thermomineral waters while 10 are acratothermal waters. Some of these waters have distinct chemical compositions. Their temperatures are between 21 and 90 °C. Various types of mineral water source occur within this region: 5 of these are sulfurous, 1 has carbon dioxide, 29 have fluorine, 1 has iodine and 3 are saliferous. The thermomineral sources with saline characteristics have balneotherapy potential for treating skin illnesses including psoriasis and rheumatological illnesses.Some waters with appreciable bicarbonate and sulfate concentrations can also be used for balneotherapy; for example for use as a cure for chronic inflammatory diseases of gastrointestinal and urinary systems. They could also be used as a cure for prophylactic and metaphylactic treatment of urolithiasis.However, among 38 sampling sites, 12 sites are bacteriologically contaminated. This indicates that regulations governing the protection of such zones are not properly enforced and that water sources within these regions are not sufficiently protected or inspected.  相似文献

The European Water Framework Directive (WFD) has driven the protection of groundwater and characterization of water bodies. Development of appropriate and efficient approaches which consider the special features of the hydrologic regime is essential. The results of different projects that have been carried out to integrate characterization and protection of water bodies are summarized herein. In the Les eaux de la Mediterranée (AQUAMED) Project, applicability to the Mediterranean Region of guidelines provided by the European Commission to facilitate the WFD implementation has been verified. The Background criteria for the identification of groundwater thresholds (BRIDGE) Project developed a methodology to establish threshold values of pollutants contributing to the chemical status of groundwater bodies. This method has been applied to pollutants used to classify groundwater bodies as at risk of not achieving objectives of the WFD. Selected features of protection areas for drinking water and safeguard zones are analyzed, as well as the possibility of using wellhead protection areas.  相似文献

This paper deals with the environmental characterization of the “Collao de Candela” enclave (Alicante, SE Spain), which in the early 1980s reported strong mining activity mainly due to the extraction of marls. The subsequent abandonment of such quarries produces floods in depressed areas that are constituted as pools. These anthropogenic wetlands are the object of this research. In order to characterize the geometry of the studied wetlands a bathymetry was carried out. Bathymetric data are very important for water managers tasked with assessing wetlands’ status. A chemical and mineralogical characterization has been carried out on the lithologies in the study area. A study was also conducted of the physical and chemical parameters of the waters contained in these pools during one hydrologic cycle. The climate of the zone, having elevated evapotranspiration measurements, favors a progressive concentration of salts in the pools consequence of runoff water washing, the evaporitic sediments as well as from elevated evaporation. The results obtained justify the environmental protection of these marl-gypsum mining quarries as potential wetlands.  相似文献

深圳市东湖矿泉水形成机理探讨   总被引:5,自引:0,他引:5  
深圳市东湖矿泉水是自然界十分稀少的锶—锌—偏硅酸碳酸复合型矿泉水,通过对矿泉水赋存地的地质与水文地质条件的分析,并结合其水文地球化学特征,认为东湖矿泉水形成的主要控制性因素是构造作用和变质作用;在特定的水文地质条件下,深部碳酸盐类岩石受热硅化变质而产生大量CO2气体,使得各种化学元素在含有大量CO2的地下水的溶滤作用下不断迁移和富集而形成该区地下水中良好的元素组合。在其特征成分中,偏硅酸来自裂隙渗透水的溶滤和岩浆期后热液水的作用,微量元素锶主要来源于钾长石、钙长石,锌则主要来自岩浆活动以及岩脉中的黑云母、角闪石、辉石等铁镁硅酸盐矿物;并认为目前矿泉水含水层仍处于良好的地质环境保护下。  相似文献

太原盆地是新生代断陷盆地, 盆地内受南北和东西多组断层控制形成了多个断垒、断块, 岩溶热矿水主要分布在三给地垒以南和田庄断裂以北的区域。岩溶热矿水的主力产水层为奥陶系的峰峰组和上、下马家沟组的碳酸盐岩储层。项目组采集了18个地热水样品, 同时收集了已有文献中的9个地热水和3个地下冷水的水化学数据。根据分析化验结果, 岩溶热矿水的水化学类型为SO4-Ca ·Mg型。根据热矿水中的离子浓度关系和主要矿物的饱和度指数可以推断水化学类型主要受石膏层的影响。地下水溶滤过程中除了方解石与白云石溶解作用外, 石膏的溶解作用占主导地位。根据矿物饱和度指数, 石膏溶解产生过多Ca2+以及热矿水温度的升高还导致了方解石或者白云石更加饱和, 可能发生沉淀。西温庄隆起内的岩溶热矿水混合了古水, 年龄均大于20 000 a, 岩溶热储温度为72.6~91.1 ℃, 循环深度为2123~2663 m。长时间的水岩相互作用, 为热矿水的形成提供传导加热的时间和丰富的矿物质组分。西温庄隆起作为岩溶热矿水温度、TDS以及锶浓度的高值区, 是盆地内热矿水的汇水区, 同时也是区域热矿水条件最好的区域。TDS和Sr浓度升高趋势反映了地下水从补给区到盆地内排泄区明显的溶滤作用, 并且发生了由低TDS的HCO3-Ca ·Mg型地下冷水往高TDS的SO4-Ca ·Mg型岩溶热矿水的发展。  相似文献

This study investigates the origin and chemical composition of the thermal waters of Platystomo and Smokovo areas in Central Greece as well as any possible relationships of them to the neighboring geothermal fields located in the south-eastern part of Sperchios basin. The correlations between different dissolved salts and the temperature indicate that the chemical composition of thermal waters are controlled by, the mineral dissolution and the temperature, the reactions due to CO2 that originates possibly by diffusion from the geothermal fields of Sperchios basin and the mixing of thermal waters with fresh groundwater from karst or shallow aquifers. Two major groups of waters are recognized on the basis of their chemistry: thermal waters of Na–HCO3–Cl type and thermal waters mixed with fresh groundwater of Ca–Mg–Na–HCO3 type. All thermal waters of the study area are considered as modified by water–rock interaction rainwater, heated in depth and mixed in some cases with fresh groundwater when arriving to the surface. Trace elements present low concentrations. Lithium content suggests discrimination between the above two groups of waters. Boron geochemistry confirms all the above remarks. Boron concentration ranges from 60 μg L?1 to 10 mg L?1, while all samples’ constant isotopic composition (δ11B ≈ 10 ‰) indicates leaching from rocks. The positive correlation between the chemical elements and the temperature clearly indicates that much of the dissolved salts are derived from water–rock interactions. The application of geothermometers suggests that the reservoir temperature is around 100–110 °C. Chalcedony temperatures are similar to the emergent temperatures and this is typical of convective waters in fault systems in normal thermal gradient areas.  相似文献

The study area is located in the northwestern part of Greece, in Aitoloakarnania prefecture. In this region, where no volcanic activity exists, thermal springs such as Kremasta and Kokkino Stefani, well-known for their healing properties occur. The objective of this study was the investigation of these springs, as well as the study of the chemical composition and origin of water. Relationships between these springs were also examined. The geological setting of the area comprises sedimentary rocks of the Pindos, Gavrovo-Tripolis and Ionian geotectonic zones, deformed by orogenic movements followed by Neogene extensional tectonism. The thermal and mineral springs were classified into three main groups. The first group is characterized by Ca-HCO3 water type and low water temperatures. It corresponds to the springs that are hosted in the Ionian zone and their possible enrichment in SO4 is mainly attributed to the evaporites. The other two groups consist of alkaline thermal water mainly hosted in the formations of Gavrovo-Tripolis zone. In these two groups, the very strong reducing conditions that prevail are expressed by high amounts of NH3 and H2S. Moreover, Na, F, Li, Sr and Ba display elevated concentrations. The second includes mineral waters of (Ca)-Na-HCO3 type that are depleted in calcium. Their residence time is rather long and they originate from deep water circulation through siliceous rocks. The third group includes thermal waters of Ca-Mg-Na-HCO3 water type of higher water temperatures that reveal characteristics of deep circulation directly associated with the underlain limestones.  相似文献
