Faecal coliform counts ranged between 5.9 x 103 and 2.3 x 104
cfu/ml for Tshwane River water, between 2.6 x 102 and 7.0 x 103
cfu/ml for Lefatlheng Well water, between 9.0 x 101 and 2.6 x 102
cfu/ml for Tlhaloganyo rain water, and between 1.0 x 101 and
7.0 x 102 for Tlhaloganyo groundwater (Table 2). These counts
were far above 0 cfu/100 ml, which is the maximum recommended
limit for no risk (DWAF, 1996). These results suggest
faecal pollution of the water sources, and implies that these water
sources pose a serious health risk to consumers. When faecal
coliform counts are greater than 20 per 100 ml, as observed from
all the water sources examined in this study, there is a significant
and increasing risk of infectious disease transmission (DWAF,
1996).
