COMPARATIVE STUDY OF PHYSICOCHEMICAL ANALYSIS OF BOREHOLE AND SACHET WATER.
Abstract
The quality of drinking water obtained from sachet and borehole sources has been assessed by
means of different parameters, which include pH, conductivity, turbidity, hardness, total dissolved
solids and heavy metal concentration. The resultant analyses revealed that sachet water is within
the limits of WHO standards; hence, pH = 6.53, conductivity = 1000 µS/cm, turbidity = 5 NTU,
and hard in classification with 60 mg/L total hardness. On the other hand, the borehole water had
a low pH of 5.39, high turbidity of 10 NTU, high hardness (calcium: 150 mg/L; magnesium: 160
mg/L), and high, unsafe levels of heavy metals like lead and zinc. These findings have shown the
quality of sachet water to be better compared to the borehole water, hence the need for sustainable
monitoring and management practices to ensure access to safe drinking water.
