nd indicators.
The greatest values of correlation coefficient between
both microbial parameters were obtained for
faecal coliforms (r = 0.66), and C. perfringens spores
(r = 0.63). The highest values of regression line slope
(m = 0.77) is shown by the C. perfringens spores.
The lowest correlation coefficient and slope values
(r =0.47; m =0.42) were obtained between
Salmonella and faecal streptococci.
