The investigation of gaseous pollutant layers depth with hydrogeochemical and geoelectrical data in chahardoly plain

The studied area is located at Qorveh region, NW of Hamadan. The pollution of water resources with CO2 is the main problem in the studied area. Destruction of water resource, existence of hygiene and economic problems are its results. Main changes in drinking water quality in chahardoly plain, is a evidence for ground water resources contamination. In this work, hydrogeochemistry and geoelectrical datas have used to Investigation of pollutant layers depth for chahardoly plain. According to vertical hydrogeochemical and resistivity investigations of sedimenthorizons, field investigations and observation in drilling sites, the depth of gas rich layer is estimated about 50-60meters.
