Hypothesis
The study aims to control physico-chemical parameters in wastewater samples and identify pathogenic bacteria.
Conclusion
Wastewaters contain a large amount of pathogenic bacteria that present a real impact on human health.
Supporting Evidence
- 76.6% of wastewater samples contained pathogenic E. coli.
- 66.6% of samples showed the presence of Salmonella in entrance points.
- Physico-chemical parameters indicated that wastewater treatment was not fully effective.
Takeaway
The study found that wastewater in Tunisia has harmful bacteria that can make people sick, even after treatment.
Methodology
Sixty wastewater samples were collected from fifteen different regions in Tunisia, and both physico-chemical and microbiological analyses were performed.
Limitations
The study did not guarantee the complete elimination of pathogens after wastewater treatment.
