Abstract
The physico-chemical and microbial analysis of surface water from Mimyak river were carried out to determine its
suitability for domestic consumption. Analysis was done using standard methods. The average results of physicochemical
parameters are: pH ( 7.03 ± 0.17, 5.23 ± 0.17), turbidity (3.75 ± 0.79, 11.64 ± 5.75 NTU), TDS (0.17 ± 0.07, 0.57 ±
0.03mg/l), conductivity (94.50 ± 8.23, 142.75 ± 53.82µs/cm), Total alkalinity (44.50 ± 6.23, 106.75 ± 27.81mg/l), Total
hardness (55.75 ± 6.87, 60.50 ± 21.90mg/l), sulphate (18.52 ± 4.60, 18.38 ± 4.53mg/l), phosphate (37.00 ± 9.23, 2.64 ±
0.90 mg/l), and chloride (7.090 ± 0.00, 7.090 ± 0.00mg/l) during rainy and dry seasons respectively. All the metallic
elements analyzed are within the WHO standard limits with the exception of trace metals such as Pb (0.014 ± 0.001,
0.010 ± 0.005mg/l), As (0.010 ± 0.005, 0.020 ± 0.007mg/l), Cd (0.01 ± 0.005, 0.04± 0.011mg/l), Cr (0.06 ± 0.022, 0.030
± 0.010mg/l) which are high. Also, the microbial analysis revealed the presence of Salmonella and Shigella,
staphylococcoci aureus and proteus with E. coli, and pseudomonas species found only in some of the samples and thus,
the water cannot be used as potable source of water.
