TheStudies on Water Quality for Cobalt and ManganeseContent in Drinking Water of Multan Area, SouthernPunjab, Pakistan

The trace elements, cobalt(Co)and manganese(Mn)were determined in the drinking water ofMultan city and areas in its vicinity. For this purpose, ten water samples were collected fromvarious points within a circle of one kilometer radius, each time around seven disposal units.Water samples were stored in sealed glass flasks at room temperature. The quality of these watersamples was compared with reference samples collected from various far off places which werenot affected by any disposal unit. Analysis forCoandMnwas carried out using Flame-AtomicAbsorption Spectrophotometer. The highest concentration ofCo(0.31 ppm) was found in NewMultan disposal area,while highest concentration ofMn(0.45 ppm) was noted in Suraj Mianidisposal area. The contents of Co and Mn metals in most of the points are found to be greater thanpermissible limits of WHO guide lines for drinking water.
