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
