المستخلص: Consumer quality confidence of the bottled and canned water is almost taken for granted, such blind certainty belief eliminates any hesitation or applying a second thought on the possibilities of potential risks present. Such self-promoted trust makes people think that this type of water is always very clean with balanced quantities of salts, minerals and microbial free. As a result, most individuals are inspired to buy and consume any bottled water brand available in the markets and this type of water is permanently preferred to the other tap or well water. The aim of current study is to evaluate consumer quality confidence. random samples of the retailed bottled drinking water Were collected prom Sabratha and Surman supermarkets and grocery stores. Every sample was subjected to Physical, and Microbial contents analysis and then evaluation and results compared to the current Libyan Standard (LS) values. Approved methods, validated instruments and reagents were used to analyze the randomly 19 collected samples for Total Dissolved Solids (TDS), pH, total aerobic bacterial count, Escherichia coli, Coliform, Pseudomonas aeruginosa, Yeast and Mold count. Of the nineteen bottled samples tested, (TDS) content had ranged from: 15.40 to 97.35 mg/l, the pH values were between 5.76 to 7.19 and total aerobic bacterial counts fluctuated from 0 to uncountable quantities. Eight (42.11 %) of the 19 brand of bottled water were categorized to be unsafe for consumption. They were 36.8% total aerobic, 10.5% coliforms, 10.5% P. aeruginosa and 26.31 yeast. 100 % of the collected reusable 18 liters bottles samples found to be contaminated with various bacteria’s. The study concluded that Some of the examined samples (both single use bottled water and reusable 18 liters bottles) TDS values were very low, others contain a very dangerous bacteria and this due to either the complete absence or poor disinfectants systems in those bottling plants and all of reusable 18 liters bottles samples found to be contaminated with various bacteria’s and this due to the absence of bottles disinfects or sterilization prior their refilling.
