| Abstract | Geochemical characteristics and arsenic content of groundwater in the Kurdistan and West Azerbaijan provinces (west of Iran) were analyzed. Groundwater is the local source of drinking water and travertine springs are mainly used for bathing and balneological purposes. The results indicate that total arsenic in travertine springs and groundwater range between 212 to 986.9 and 0.4 to 688.9 μg/L, respectively. Speciation of arsenic suggests arsenite the dominant arsenic species in travertine spring (68.2 to 98.9%). The variations of Br/Cl and B/Cl ratio, negative ORP (Oxygen Redox Potential) and high concentrations of Cl, Na, Cs, Li, Rb, Sr, B, Br and Rb in travertine spring samples confirm deep groundwater circulation in the volcanic basement. The results of saturation indices show that groundwater samples are supersaturated with respect to iron oxides, calcite, dolomite and aragonite and undersaturated with respect to gypsum and halite. In spite of gold mineralization, dissolution of arsenic-containing sulfide minerals is not the main source of arsenic contamination in groundwater. Spatial coincidence between the arsenic anomaly in groundwater and the travertine springs distribution illustrates they are the main source of arsenic in groundwater. The present study is useful in addressing future measures in groundwater resource management, in the volcanic regions in the west of Iran. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
