Abstract
A comprehensive Laboratory assessment involving the physical and chemical analysis of nylon packed sachet water popularly known as pure water within the Ado-Ekiti metropolis in Ekiti state has been carried out. This is in view of the increasing number of the sachet water production factory due to growing population of the people within the metropolis and the need to generally investigate them to know the ones good and safe for domestic consumption. A total of fifteen (15) sachet water samples from different location within Ado-Ekiti, the area of study were collected and analyzed. The test was carried out using the pH comparator, turbidimeter, Lovibond comparator, and the caliform test for pH, turbidity, colour test respectively. The ionic concentration was also determined by adding some reagents and exposing it to the source of light. The result of the analysis shows that he sample has a pH value ranging from 5.11-7.52, Alkalinity 16-160, Electrical conductivity 29-417 ys/cm, Turbidity of the water sample ranges from 5.3-9.3, the total dissolve solid (TDS) ranges between 9.0 to 107mg/l/. The range of few ions like Iron (Fe), Sulphate (SO42-), Chloride (Cl) and Nitrate (NO3-) analyzed in mg/l ranges between 0.1-1.0, 182-256, 14.58-29.15 and 48-71 respectively. The result of the analysis falls within the permissible limit and conforms with the standard recommended by NAFDAC, WHO and UNICEF.
