Abstract
This study was undertaken to determine the changes in the
physico-chemical properties of piped water supplied in the state,
between the treatment plant and points of use in Ile-Ife, Nigeria.
Thirteen samples of water were collected at different locations from
treatment plant to the points of use and analyzed for the following
selected parameters: alkalinity, total dissolved solids, total
suspended solid, total solid, potassium, sodium, calcium, magnesium,
trace metals, sulphate and chloride. The results revealed that between
treatment plant at Ede and the point of use, there are changes in the
considered physico-chemical properties of the water supply.The most
significant is the concentration of lead ion which was higher than the
recommended 0.01mg/L by the world health organization and total
alkalinity with a mean value of (325.36±81.85) mg/L. The study
concluded that the treatment process needs to be reviewed to identify
the possible source of the ion and put necessary prevention procedures
