Abstract: It
is needless to say that the quality of water is of vital importance to public
health. Efficient surveillance and check strategies are important for executing
a high quality management of this resource. Fourty eight water samples were
collected randomly from different localities within Tabuk in the period
between April 2012 and July 2012. Water samples were
subjected to Chemical, Bacteriological and Parasitological
examination. Drinking water samples taken in the study are almost
following the WHO and US-EPA standards with few exceptions in the TOC ( 41.2%),
Fluoride (33%), Hg (17% ) , but the alkalinity of water does not make it very
harmful. Tap water is more alkaline than other samples with higher salinity
than standard, high TDS and hence EC , it also suffer from high presence
of TOC, Fluoride, bromide and mercury, so it is least quality to be used as
drinking water. Commercial Zamzam water has proven to contain high levels of
fluoride, TOC and bromide when compared to drinking water. It also has higher
salinity % , TDS and hence higher electrical conductivity than drinking
water. For bacteriological examination, 12% of water samples were
exceeded the WHO guideline value (>10cfu/100ml), as the total coliform count
was determined on each sample through the most probable number of colony
forming units method. Parasitological examination revealed that giardia cysts
were detected in 25% of water samples and C. parvi oocysts
were detected in 16.6 % of water samples by both microscopy and ELISA
methods.
