The Physico-Chemical and Bacteriological Characterization of Domestic Wastewater in Adétikopé (Togo, West Africa)
Wastewater represents a health risk for the population. For sanitary safety, it is important to know its physico-chemical and microbiological qualities in order to better understand the risks incurred by the population. The aim of this study was to analyze Adétikopé’s domestic wastewater from a microbiological and physico-chemical standpoint. Twelve wastewater samples were taken in Adétikopé from December 2022 to February 2023. Physico-chemical parameters were determined in accordance with AFNOR and the French NF standard. In microbiology, AFNOR was used as a reference for the detection of germs contaminating wastewater. Results were assessed in relation to European Union Criteria 98/83/EC. The wastewater analyzed has a pH close to neutral, with an average pH of 7.05. The pollutant load generated ranged from 32 mG/L to 201 mg/L for BOD5, from 660 mG/L to 900 mG/L for COD and from 408 mG/L to 2080 mG/L for suspended solids. The highest levels of germs were detected in the samples taken, with values of 68,000 CFU/100 mL and 47,000 CFU/100 mL for thermotolerant coliforms and fecal streptococci, respectively. The results show that fecal contamination originates from both animal and human sources. Concentrations of fecal coliforms and fecal streptococci are very high, far exceeding WHO guidelines. While a short-term solution would be to disinfect household sanitation systems on a daily basis, in the long term, the construction of collective sanitation systems, backed up by environmental education, remains a sustainable solution for the health and safety of populations.
