About 99% of the potable water used in Qatar is desalinated and Qataris spend approximately 15 million dollars in importing
bottled water (90 million L), as the public thinks it is of better quality than the tap water. Since both tap and bottled water
are stored in plastics, there are certain factors (e.g. temperature and UV light) which might affect their quality. Till now, there
is no study available on the quality of drinking water in Qatar. This study is focused on analyzing the selected ions along with
the toxic Bromate and Perchlorate ions in tap water collected from different locations in Qatar and five commonly consumed
bottled water brands. The water samples were analyzed using the Dionex Ion Chromatography ICS 5000+. The concentrations
of selected ions (ammonium, bromide, calcium, chloride, fluoride, lithium, magnesium, nitrate, nitrite, potassium, sodium and
sulfate) were found to be below the set standard levels. The toxic Bromate and Perchlorate were not detected in any of the water
samples tested in this study. However, the concentration of phosphate ions in all tap water and 5 bottled water brands ranged
from 0.37-0.69 ppm which is above the standard (0.1 ppm) set by the Water Authority in Qatar, indicating that phosphates
might have been added to drinking water to avoid corrosion in pipes. In conclusion, both tap water and bottled water brands
studied are safe for consumption with respect to all ions. However, more research needs to be carried out to collect samples
from the same locations during different times of the year to determine the impact of environmental factors on the formation
of toxic Bromates and Perchlorates. Additionally, the public in Qatar should be encouraged to drink tap water since its quality
is very much comparable to the bottled water, in contrast to their beliefs.
Biography
Sabah Mariyam is a Bachelor’s student of Environmental Sciences Program at the Department of Biological and Environmental Sciences, College of Arts and
Sciences, Qatar University. Her graduation project, funded by Qatar University Student grant, focuses on the quality of drinking water supplies in Qatar and this
abstract is part of that project. She aims to encourage and change the general public perceptions on tap water quality in Qatar. She will be pursuing her Master’s
degree in Environmental Sciences upon graduation.
