Arsenic (As) contamination of drinking water is now a global issue and is present, all over the world. In response to the growing concerns about this poisonous carcinogen and awareness of the dangers of As in drinking water, an exclusive study was carried out on the occurrence and distribution of arsenic in drinking water samples, collected from ten (10) villages of District Larkana, and seven (07) villages of District Mirpurkhas, in Sind province. The samples were collected from different public water supply schemes, where the drinking water quality is known to have been deteriorated. In all the study areas of Mirpurkhas, arsenic concentration was found below the maximum permissible limit as recommended by World Health Organization (WHO). An average concentration of 2.04 ppb was observed in water samples of Mirpurkhas with a narrow variation in the range of 0.40-20.02 ppb. Altogether 10% of the water samples of district Larkhana exceeded the WHO guideline of 10 ppb. As compared to Mirpurkhas, District Larkhana has appeared as a more problematic zone from the point of view of arsenic contamination in the particular study area.
