The aim of the research was to study the presence and to determine the level of arsenic impurity in Lahore’s water by employing hydride generation-atomic absorption spectrophotometry. Water samples from different educational institutes of Lahore were collected, acidified, and subjected to analysis by HVG-FAAS. The study was conducted in the Department of Chemistry, Government College University Lahore between September 2013 and July 2014. The study included 18 samples which were subjected to HVG-FAAS analysis in order to determine the concentration of arsenic in terms of parts per billion (ppb). Out of 18 samples, 17 samples had arsenic concentration exceeding the limit defined by WHO (i.e., 10.0 ppb). Only 1 sample had the concentration of 8.0712 ppb, while 1 sample particularly exceeded the limit with a large margin by having the concentration of 24.2326 ppb. The concentration of arsenic needs to be controlled by employing both natural and anthropogenic methods in order to ensure the health of the denizens of Lahore. However, complete absorption of arsenic from water can result in chronic disorders. These predictors, however, need further work to validate reliability.
