Abstract :
The study was conducted to evaluate the quality of bottled water circulating in Wadi Al-Shati- Libya, and measured some of its physicochemical and bacteriological properties and its compatibility with Libyan and WHO standards. a total of 11 brands were selected for water analysis, the results of physicochemical analyses showed a difference in the quality of bottled water. The results of turbidity ranged from 0.84 to 1.04 NTU, while pH were between 5.63 and 7.45, while the TDS was between 28-303 mg/L, The TH was between 2-36 mg/L, the calcium was between 0.4-6 mg/L, magnesium ranged from 0.24-5 mg/L, and sodium was between 2-23 mg. Potassium ranged from 0.4-17 mg/L and chloride was between 1.3-45 mg/L, while nitrate was only 37 mg/L, and sulfate was between 0-73 mg/L. The bicarbonate ranged from 4-29 mg/L, while the iron ranged from 0-0.23 mg/L, manganese was the highest concentration of 0.19 mg/L, and zinc was only 0.11 mg/L, while the highest concentration of copper was 0.017 m/l, lead was not detected in all samples. The results showed that the total number of bacteria in bottled water ranged from 0-380 ufc /ml and there were samples that exceeded the permissible limits in the Libyan prescribing of bottled drinking water, while the results of the detection of colitis and fecal colon bacteria showed that all studied samples were free of fecal colon and coli , these results conformed to Libyan standards set out in the Libyan registration Drinking Water No. 10 for 2008.
