“…Scales are generally observed with yellow and orange, and occasionally white color in the field. Marmara et al (2020) reported that the As, Fe and Mn concentrations of scale are higher than the mean values for the continental crust defined by Krauskopf and Bird (1995). Kestanbol geothermal waters are highly mineralized with elevated levels of As, Ba, Fe and Mn.…”

“…The geothermal waters are heated at depth by the Kestanbol Pluton and high geothermal gradient. Marmara et al (2020) identified the NE-SW trending right-lateral strike-slip Kaplica fault parallel to Ilica stream in the Kestanbol geothermal field. The fault begins at the contact between metamorphics and granites in the east and probably ends by continuing under the Aegean Sea in the west, reaching a length of nearly 10 km.…”

“…Previous studies were performed to identify the geological, hydrogeological and hydrochemical characterization of Kestanbol geothermal field, and to use geoelectric methods for geothermal exploration, in addition to evaluating the environmental effects of geothermal water on soil and stream sediment (Mutzenberg, 1997;Caglar and Demirorer, 1999;Baba and Ertekin, 2007;Tokcaer, 2007;Yalcin, 2007;Yalcin and Sarp, 2012;Karaca et al, 2013, Marmara et al, 2020. This study aimed to (1) determine the hydrogeochemical and isotopic compositions of geothermal and cold waters in the Kestanbol geothermal field;and (2) investigate the effect of seismic activity on variations in the hydrochemical features of the Kestanbol geothermal waters.…”

Kestanbol geothermal field is located in northwestern Turkey and is one of the highest temperature geothermal fields in the Biga Peninsula. In this study, one geothermal well, two geothermal springs and two cold springs were monitored for one year in Kestanbol geothermal field to determine hydrogeochemical and isotopic characteristics. Additionally, any possible relationship between seismic activity and variations in the hydrochemistry of geothermal water was investigated. The Kestanbol geothermal field is controlled mainly by the right-lateral strike-slip Kaplica fault with normal components. The distribution of the geothermal waters is roughly parallel to the fault. The temperature, electrical conductivity, salinity, and pH of the geothermal waters were within the range of 59.5 to 74.6 °C, 30300 to 35700 μS/cm, 19.6 to 23.3‰ and 6.13 to 6.83, respectively. The temperature interval was 11.2 to 25.4 °C for cold waters. The hydrochemical facies of the geothermal waters were Na-Cl type and the cold waters were the Ca-HCO 3 -Cl type. The high concentrations of As, Ba, Fe, Li and Mn in geothermal waters were mainly derived from prolonged water-rock interactions under high-temperature conditions. The δ 18 O and δ 2 H contents of cold waters indicated meteoric origin. The geothermal waters were enriched in δ 18 O and δ 2 H, and located on the mixing line between local groundwater and fossil seawater, indicating mixing processes. During our study period, 20 earthquakes with Mw 3.5 and above were recorded in the close surroundings of the Kestanbol geothermal field, and temporal variations in the physicochemical and chemical compositions of geothermal waters were observed. Concentrations Clof the geothermal waters exhibited decrease after the Tartisik-Ayvacik earthquake (Mw= 5.0), indicating more supplement of groundwater with shallow origin under the increase of tectonic stress.

“…Geothermal fluids of Turkey are highly mineralized with elevated levels of As, B, Cd, and Pb [13]. The high element content of geothermal fluid has certain detrimental environmental consequences, such as pollution of surface water, groundwater, and soil [14].

The heat accumulated in the inner parts of the earth's crust is transmitted to the fluid in the geothermal aquifer by means of transportation. The geothermal fluid is transported to the surface either by wells or naturally. In this study, the geothermal fluid in Tuzla geothermal field in Çanakkale city was examined due to its high boron content (10.3 mg L -1 ). It was aimed to remove boron from geothermal fluid by adsorption in order to prevent possible negative effects on the environment. Fly ash was obtained from Çan thermal power plant. The specific surface area of the fly ash was 14.6 m 2 g -1 and the particle size was between 1.45 and 186 µm. According to ASTM C618 standard, fly ash was classified as Class C. Fly ash was composed of anhydrite, lime, hematite, cristobalite, quartz, calcite and feldspar. Various parameters such as initial pH, adsorbent dosage, contact time, and temperature were studied experimentally for the removal of boron from the geothermal fluid. The suitability of pseudo-first-order, pseudo-second-order, and intraparticle kinetic models to experimental data was examined. The data obtained from the isotherm studies were applied to the Langmuir, Freundlich and Dubinin-Radushkevich models.
