Regarding the limestone characteristic, it contained high carbonate content in the limestone sample creating an alkaline condition for the water sample (Aziz et al. 2001). The finding was proved by results of XRF analysis as discussed earlier. The increase in pH may increase the removal of Fe and Mn in the samples (Aziz et al. 2004).
