The use of underground water in the eastern part of Abshe- ron peninsula

For the estimation of the quality of the reserves of underground water, the results of chemical analysis carried out in the eastern part of Absheron peninsula in various times have been used. The underground water is used both for the drinking and irrigation. The mineralization of the water is within 0.7–1.0 g/l and 1–3 g/l. The water hardness fluctuates between 6–30 mg-equ/L. Low-mineralized water may be used in purposes related to human life and technical as well. According to the results of the chemical analysis, the water is predominantly of sulfate-chloride and hydrocarbonate type.
