Analysis of the Chemical Composition of Five Brands of Bottled Drinking Water Available in Libya Concerning WHO and Libyan Standards

Abstract

Assessing the safety of bottled drinking water in Libya holds significant importance. Hence, the current research sought to contrast the chemical makeup (as indicated by manufacturers) of 5 locally available bottled drinking water brands and measure them against WHO and Libyan standards. Containers of bottled drinking water were purchased from local stores. The chemical makeup of these brands was documented from the labels and then contrasted with both WHO and Libyan standards. The pH, EC, (μs/cm), TDS (p.m), TH hardness, Ca++, Mg++, Na+, NO3-, Cl–, and Alkalinity measurements were measured. It was observed from the results that the pH levels of all bottled water brands fell within the acceptable range as per both WHO and Libyan standards. The total dissolved solids, hardness, sodium, chloride, and nitrate levels were found to be lower than the maximum limits specified by WHO and Libyan standards for either primary or secondary (aesthetic) criteria.
