Sampling and analyses of snow water at a mountainous site of northwestern Turkey were described. A snow sampler designed in our laboratory was used in the sampling. Ion chromatography, flame atomic absorption and emission spectrophotometry were very good techniques for the determinations of major ions in snow samples. The accuracy of results was tested by using different standard reference materials for both techniques. The results were in good agreement with the certified concentrations. The results of analyses were accepted if the error was less than 15%. The overall precision was in between 1-6%. The concentrations of snow samples were high compared with the literature values. The pH of them was found to be acidic with the average value of 4.3. Magnesium had the highest average scavenging ratio, and ammonium ion had the lowest average scavenging ratio. Sodium, K, Ca and Mg were mostly originated from the earth crust. Marine contribution to the sampling site was also effective.
