The poor quality of drinking water has forced a large cross-section of citizens to buy bottled water. As a consequence of this expanding market a mushroom growth of bottled water industry in the country is witnessed during the last few years. However, many of the mineral/bottled water companies were found selling contaminated water. To monitor and improve the quality of bottled water, the Government of Pakistan through Ministry of Science and Technology has designated the task to PCRWR for quarterly monitoring of bottled/mineral water brands and publicize the results. According to the monitoring report for the quarter from October to December, 2017, 131 samples of Mineral/Bottled water brands have been collected from Islamabad, Rawalpindi, Sialkot, Peshawar, Multan, Lahore, Bahawalpur, Tandojam, Quetta and Karachi. Comparison of analytical findings with permissible limits of Pakistan Standards & Quality Control Authority (PSQCA) has revealed that 12 brands (i.e. I Pure, Aqua National, SN Pure Drinking Water, Snow Dip, Orion, Abe-Khyber, Orabel Pure Water, Life Water, Athar, Oasis Plus, Heaven H2O and Fino) were found to be unsafe due to chemical and microbiological contaminations. Out of those unsafe brands, 2 brands (i.e. Aqua National and SN Pure Drinking Water) have comparatively high levels of Arsenic ranging from 17.5-35.5 ppb than PSQCA water quality standard for arsenic (10 ppb). The excessive level of arsenic can cause various types of skin diseases, diabetes, kidney diseases, hypertension, heart diseases, birth defects, black foot diseases and multiple types of cancers etc. The 7 brands
(i.e. Abe-Khyber, Orabel Pure Water, Life Water, Athar, Oasis Plus, Heaven H2O and Fino) were found to be unsafe due to microbiological contamination which may cause Cholera, Diarrhea, Dysentery, Hepatitis, Typhoid etc. Whereas 2 brands (i.e. Snow Dip and Orion) were found unsafe due to the presence of higher levels of Sodium ranging from 60-110 ppm than PSQCA water quality standard for sodium (50 ppm) and 1 brand (i.e. Snow Dip) was found unsafe due to the presence of higher level of Potassium and TDS.
