Van Lake Basin is in a closed basin, and there are many saline water sources. In this study, the characteristics of other saline water sources were investigated outside Van Lake. Material and Methods: In the study, measurements were made with multimeter at 7 points in July 2019, and heavy metal pollution index values were calculated. In addition, nitrite, nitrate, phosphate, phosphorus, sulfate, fluoride, cyanide, turbidity, total suspended solids and silicon analysis were also performed with titrimetric analyses. The results obtained were evaluated according to the relevant water quality regulations. The average temperature as 23.5±1.8 (13.8-27.4) °C, dissolved oxygen (DO) 11.36±1.56 (6.91-17.70) mg L-, salinity 3.67±1.47‰ (0.71-12.16), electrical conductivity (EC) 6452.4±2350.0 (1087.0-19730.0) μS cm-1 and pH 9.02±0.50 (6.21-10.13) were measured. The concentration of copper, cadmium, lead and selenium from heavy metals were not determined. The heavy metals from the highest value to the lowest one were Mo> Mn> Al> Zn> Fe> Cr> Co> Ni> As. The average value of heavy metal pollution index (HPI) determined by heavy metal results was calculated as 147.4±25.2. Saline water samples are generally classified as “unsuitable water“ according to HPI quality class. N1 was the only station in the “good” class. The sample points of N2, N3, N4, N5, N6 and N7 are included in the “unsuitable water“ class.
