“…The substantial germ pollution found in our samples follows what was reported in a water quality study in artesian boreholes in Dogbo Ahomey in the district of Tota, municipality of Dogbo in Benin. Their hypothesis for the high rate of microbial contamination in the various sites investigated was poor protection of these boreholes (Hounkpatin et al 2021).…”

“…Although the borehole water quality is found to be better than the water from other sources like drilling, rainwater, and surface water, as described in a study on the microbiological quality of drinking water in the Ahomadégbé district (Johnson et al 2016), it might still not be compliant with WHO standards with the presence of presumed coliforms and thermotolerant coliforms as observed in our samples. Households in rural areas living in hygienically critical conditions often introduce fecal contamination into drinking water during transportation and storage (Meierhofer et al 2018;Hounkpatin et al 2021). That is why residual chlorine is vital in water at the community level to avoid water recontamination following the immersion of unclean fingers or storage in a dirty container.…”

This paper evaluates the performance of a low-cost technology in rural Benin (West Africa) that locally produces chlorine (sodium hypochlorite) and then injects it into the community water tanks. Thirty-one water tanks were selected in cooperation with local authorities to receive electro-chlorinator devices (WATA™). Water samples were tested at two points: before chlorination and at the most distant terminal after chlorination. Residual chlorine control tests and microbiology control tests were performed. Water samples that tested positive for the presence of microorganisms were analyzed at a laboratory when possible. The water provided to the community was not always chlorinated, and over half of the tanks lacked access to chlorine powder. Among the sites using the technology, 30% (9/31) of them had structural problems that prevented the existing system from performing adequately. Furthermore, 60% of the water samples collected before chlorination were positive for microbiological contamination. All samples collected from systems where proper chlorination was taking place tested negative for microbiological contamination. However, the water from six tanks presenting structural problems continued to be distributed to the population despite contamination. The average residual chlorine level analyzed at the most distant terminal fountain was 0.29±0.2 mg/L, which is within the country's reference level 0.1–0.8 mg/L. The installation of water-chlorinator devices (WATA™) produces water without microbiological contamination and with chlorine levels within the WHO's recommended values. However, the success of the technology depends on the pre-existing structure of the water tank.

O crescimento urbano desordenado e a intensificação de construções inapropriadas de fossas para recebimento dos esgotos domésticos, somado à falta de adequação do despejo do esgoto domiciliar e à distribuição inadequada da água tratada, culminam na contaminação da água dos poços artesianos em áreas urbanizadas. Este estudo propôs avaliar a qualidade da água de poços artesianos no Bairro Monteiro, localizado em Pio XII, estado do Maranhão. O estudo foi desenvolvido com amostras de água coletadas em dez poços artesianos. As análises da água foram compostas por análises parasitológicas, físico-químicas e microbiológicas. Os resultados das análises físico-químicas da água revelaram que a maioria dos poços artesianos apresenta valores que se encontram dentro dos padrões de potabilidade estabelecidos pelo Ministério da Saúde. No entanto, destacam-se alguns resultados específicos: o poço 2 apresentou um pH ácido (5,70), enquanto os poços 1, 9 e 10 demonstraram níveis elevados de íon nitrato (NO-3). As análises de coliformes totais indicaram a presença em 9 dos poços contaminados, sendo que três deles apresentaram contaminação por Escherichia coli e Enterobacter cloacae. Além disso, foi identificado que os isolados bacterianos apresentaram resistência a pelo menos dois antimicrobianos, com destaque para o antimicrobiano ampicilina + sulbactam, seguido de ceftriaxona.
