TC, total coliform; EC, Escherichia coli; E, Enterococci. Maxima and minima bacterial counts obtained from three sampling sites. Statistically significant correlation coefficients with . All analyses from the three sampling sites were performed in triplicate and the standard deviations were less than 1.5% of averages.
