“…As in the case of EC, this situation is also attributed to the hot geothermal water intrusion to the surfacial aquifer. The results of a previous study also verify this finding and reports that sodium is one of the main elements in the waters of the geothermal fields in Simav Plain (Gemici & Tarcan, 2002). When EC and SAR are combined to assess the infiltration hazard, it has been found out that these areas where groundwater is affected from the intrusion of geothermal fluid demonstrate moderately suitable areas for irrigation water extraction as high SAR and EC values counter balance the negative effects of each other.…”

“…In addition, it is also believed that a secondary reservoir system has developed in the young volcanic system located underneath Simav Plain as a result of basalt intrusion and lava flow. The bore log data obtained from a geothermal well indicates that the thickness of these Neogene-aged and volcanic reservoir rocks reach a total of about 400 m (Gemici & Tarcan, 2002).…”

The irrigation water quality and the associated hazards to soil characteristics and crop yield is often a complex phenomenon that involves the combined effect of many parameters. From a management point of view, it is sometimes necessary to analyze all related parameters as a combination rather than focusing on a single isolated parameter. With this objective in mind, a new GIS-integrated tool is proposed in this study to evaluate the quality of irrigation waters with regards to potential soil and crop problems. The proposed procedure is mainly an index method that utilizes five hazard groups: (a) salinity hazard, (b) infiltration and permeability hazard, (c) specific ion toxicity, (d) trace element toxicity; and, (e) miscellaneous impacts on sensitive crops. A linear combination of these groups is formulated to form the so-called IWQ index, which is a technique that could be used to classify irrigation waters with respect to three suitability classes. The proposed technique is applied to assess the irrigation water quality of the Simav Plain located in western Anatolia, Turkey. The Simav application is implemented by using a GIS database developed for the plain. Based on the results of this application, the general groundwater quality in the surfacial aquifer is found to be fairly good and the aquifer waters are mostly suitable for irrigation purposes.

“…Peloids P-11 and P-12 are formed from the units. Paleozoic to Early Mesozoic metamorphic rocks, e.g., gneiss, schist, marble, and ophiolites, and Late Eocene to Middle Miocene basaltic, andesitic, dacitic, and rhyolitic lavas and pyroclastic rocks are overlain by Upper Miocene to Pliocene lacustrine and fluvial deposits (Gemici and Tarcan, 2002;Mutlu, 2007). The samples numbered P-13 to P-15 have been used as peloids, which were taken from the deposits.…”

Thermal muds have been used in many spas for the treatment of different diseases as well as to clean and beautify the skin and in different forms such as mud baths, masks, and cataplasms. Mineralogical and chemical compositions and the possible toxicity of the peloids were investigated and compared with some limits to determine whether they have any health benefits and potential applications for pelotherapeutic treatments. The studied peloid samples were collected from 19 spas in different parts of Turkey and they were classified as neutral to slightly alkaline, with a high electrical conductivity value that had a high chlorine content and was regarded as highly conductive. The temperature of the peloids was between 23.2 and 61.0 °C. The mineralogical composition mainly comprised smectite and illite, partially quartz and feldspar, some carbonate (calcite and dolomite), and other minerals. The most abundant clay mineral was Ca-montmorillonite. The major and trace element contents of some of the peloids were similar to each other, while the contents of some toxic elements showed a clear variation. Toxic element contents, e.g., As, Cd, Hg, Pb, and Sb, of the peloids were higher or lower than the commercial herbalist clay, pharmaceutical clay, natural clay, average clay, and Canadian Natural Health Products Guide. The toxicity of some hazardous elements was compared, especially that of the pharmaceutical clay, and evaluated together with other parameters. Toxic elements were higher than in the pharmaceutical clay in most of the peloids.

“…The many geothermal water sources were formed in the region as a result of the formation of the Büyük Menderes graben and high concentration of boron (B) in some water resources was reported [9]. The contamination of the hot-water resources with high boron consantration is one of the most important source the high concentration of B in irrigation water resources like well and surface water especially Büyük Menderes River.…”

“…Recent studies [17,18,24] have shown that boron toxicity is a major problem at Büyük Menderes valley because of activity of geothermal power plants and their discharge of geothermal waste water due to drilling well to have effiancy and take it under control and into next stage due to holding electrical energy by using flash methode. Fluids emerging from some of these areas contain high boron concentrations and cause environmental problems for irrigation waters in agricultural areas where boron contaminates aquifers and soils [9]. Boron has accumulated in the plants more than required in the area [19].…”

Abstract. Geothermal energy is classified as a clean and sustainable energy source, like all industrial activities, geothermal energy power plants (GEPP) technology has also some positive and negative effects on the environment. In this paper are presented by attent not only on environmental impacts of GEPP onto Büyük Menderes River and fresh water sources, which ere used for irrigation of agricultural fields from tousands of years in basin, but also on water quality contents like heavy metals and gases emition due to drilling and electricity producing technology of GEPP's. Aydın province is located in the southwestern part of the region and its city center has around 300000 population. The high geothermal potential of this region became from geographical location, which is held on active tectonic Alpine-Himalaya Orogen belt with active volcanoes and young faults. Since 1980's to 2016 there is about 70.97% (662.75 MW) of installed capacity by according to the Mineral Research and Exploration General Directorate, there are totally 290 well licensed (540 explore licenses and 76 business licenses), and 31 geothermal powerplants purposely installed. Topic is important because of number of GEPP increased rapidly after 2012 to now a days to 36 in whole basin.
