Figure 1.

Visual representation of minimum and maximum concentration (Log_10/L) of selected microorganisms in partially treated and untreated wastewater intended for reuse. The numbers on the bars represents the individual references with these reported concentrations. These articles are referenced in Table 1, where further information is provided. This is a brief introduction of the different concentrations reported in literature for the different categories of microorganisms. Table 1 gives detailed information on the literature added in this figure.
