Determination of pH, Ca2+ and Cl- in packaged pure water consumed in Plateau State

Abstract

This work was designed to check the NAFDAC status, pH values, Chloride and Calcium ions concentrations of the samples. Ten specimen samples of the commonly consumed pure water were randomly selected and bought from the market for the analyses. The results show that only 40% were registered with NAFDAC and only10% had the batch product checked by NAFDAC; Chloride ion concentration was generally low ranging between 1.54mg/l and 18.23 mg/l; Calcium ion concentration was also low ranging between 5.6 mg/l and 40.21 mg/l. 50% of the samples had PH less than 6.5 while non-had PH above 8.5. The water samples were found not to meet set standard. This implies that the consumers are at risk. Therefore the Supervisory Agencies are called upon to insist upon checking every product no matter the location while producers should be quality conscious.
