Pharmaceutical in water and food even in low concentration have shown potential risks to human. Acetaminophen and ibuprofen are among a set of the most prescribed drugs in the world. In this study raw water and treated drinking water from Latyan drinking water treatment facilities were analyzed to determine possible concentration of acetaminophen and ibuprofen in water. All the data were subjected to analysis of variance to consider significance of differences. Furthermore mean comparison between data was calculated using Duncan test. Presence of acetaminophen in the ground water resources was not reported. While in the Jajrood river and Latyan Dam Lake the concentration of acetaminophen were 2.16 ± 0.09 and 9.17 ± 0.18  ηg L-1 respectively. In the case of ibuprofen the only observed concentration was equal to 11.49 ± 0.33 in the Latyan Dam Lake. No concentration of acetaminophen and ibuprofen was detected in drinking water samples gathered after treatment process.Why pharmaceuticals were known as indicators for controlling the quality of raw water and the treatment efficiency in the drinking water treatment facilities, ground water and treated water of this area are safe with no detection of acetaminophen and ibuprofen.
