Karstic groundwater in many parts of the world is as sources of drinking water. The karst environments, according to certain morphological characteristics that are, in some areas the disposal of, industrial and agricultural leachate and household waste and other waste materials are used. And this could lead to pollution of groundwater in these areas. Karst water pollution threatens human health. In this study karst area of the Takhte Sloyman (Afshar) in the South East of West Azerbaijan province and northeast of the Tekab city being involved in the study. The study area is located between the 36 ° 30' and 37 ° 30' N latitude and 47 ° 05' and 47 ° 45' E longitude. To evaluate the quality of drinking karst water in area initially, the water was sampled. And the Laboratory of metals (Pb, Fe, As, Na, K, Ca, and Mg) and total solids were measured with the use of atomic absorption spectrometry. Based on the analysis results in terms of milligrams per litre are: Lead (0.042), arsenic (0.052), iron (0.002274), Na (2.790), potassium (1.578), calcium (5.509), magnesium (43.381) and total solids (329) mg/L. The results show that the maximum concentration of heavy metals such as arsenic and lead measurement exceeds the maximum allowed for drinking water. Concentrations of heavy metals and other light elements is less than the amount of drinking water standards. High levels of lead and arsenic from drinking water limit is a threatening factor for human health. If the water consumed by residents leads to digestive diseases, blood poisoning and kidney function is impaired. In order to protect the health of the residents of the area should be done to solve the problem seriously.
