Table 3.

Difference in microbial (V.cholerae) count (10⁻²) among 3 plants, using ANOVA.

PLANTS	N	Mean of Count ± S.E.M	F	P
cof WWTP	18	18.17 ± 8.23	26.78	0.00 *
QT WWTP	18	244.61 ± 44.86
Cath WWTP	18	0.00 ± 0.00
Total	54	87.59 ± 21.36

* Significance: p < 0.05. The result presented in the table shows that there is a significant difference among: cofWWTP (Mean = 18.17, SEM = 8.23); QTWWTP (Mean = 244.61, SEM = 44.86) and CathWWTP (Mean = 0.00, SEM = 0.00), (p < 0.05). the mean values obtained showed that, the microbial count was higher at QTWWTP.
