the mean values of total coliforms were 7.5×105± 3.9×105, 8.25×102± 5.04×102, 8.2×104±4.1×104, 4.83×102 ± 3.15×102 and 2.72×103± 9.5 ×102 cfu/mlorg., respectively.
while the mean values of faecal coliforms were 2.8×104± 1.5×104, 1.16×102 ± 7.11×10, 1.02×103 ±1.71×102, 2.01×10± 1.07×10 and 3.13×102±1.30×102 cfu/mlorg., respectively.
