“…Table 2, shows the heterotrophic bacterial counts from the soil samples. It was observed that soil samples from Adeola Odeku and Dolphin had lower counts respectively compared to the control garden soil sample which is as a result of altered pH of the soil which hindered bacterial growth Udochukwu et al, (2016a) and Atuanya et al, (2016b) also observed similar trend in their work on ecotoxicological effects of plastic waste on soil and soil biological sentinels. The bacterial toxicity test showed that the toxicity of the solid waste composted soil samples was higher than that of control soil samples.…”

The effects of solid waste on soil and soil sentinels cannot be over emphasized. On the other hand, managing municipal waste has a serious challenge. This study focused on the impact of solid waste on soil bacteria and the municipal waste management in some communities of Lagos Island which are Dolphin and Adeola Odeku Village. This study aimed at examining the present municipal waste management practices in Lagos Island and how they can be improved upon. Random sampling was used to administer 100 questionnaires to households while the different heavy metal concentrations in the soil samples were determined using Buck 200 Atomic Absorption Spectrophotometer (AAS). The wastes were mainly composed of food wastes, plastics/pet bottles and nylon. Although the majority of the respondents (65%) had waste bins/bags assigned to their houses, about 73.86% did not sort their wastes. The concentrations of the heavy metals (Co, Zn, Ni, and Mn) in the soil samples were higher in Dolphin and Adeola Odeku village compared to the control soil sample. The bacterial isolates identified from the soil samples are Corynebacterium spp., Enterobacter spp., Flavobacterium spp., Acinebacter spp., Escherichia coli, Proteus spp., Bacillus subtilis and Micricoccus leteus. SWOT analysis revealed the need to improve environmental awareness to minimize the threat of low sorting of wastes. Also, opportunities exist for recycling plastics/pet bottles and nylon while wastes from food materials could benefit agriculture through composing. This study suggests that more environmental awareness, policies, and better administration are needed to improve the status of waste management in urban communities of Lagos Island.

“…Selon Prescott et al (1999) les microorganismes changent fréquemment le pH de leur milieu de vie en produisant des produits métaboliques acides ou basiques. Le même ordre de grandeur de pH est rapporté par Atuanya et al (2016) au Nigéria ; et inférieur à celui trouvé par Adekunle et al (2004) au Nigéria.…”

“…Les longues périodes d'utilisation des filtres dans les machines d'ensachage des ʺpure waterʺ, constatée lors de l'enquête, pourraient ainsi favoriser le passage des particules en suspension dans l'eau emballée et par conséquent augmenter sa turbidité. Ces valeurs de turbidité sont largement supérieures à celles obtenues par Atuanya et al (2016) lors d'une étude similaire au Nigéria.…”

In recent years, sachet water known as "pure water" has gained the confidence of the Nigerien public because of its low price, availability, convenience, and quality perception by consumers. This study highlights the impact of storage on the quality of pure water sold in Niamey. Thus, eleven of the twelve analyzed physicochemical parameters have been monitored during six weeks of "pure water" storage in the sun and at laboratory ambient temperature. From the results obtained, the physicochemical parameters are in norms except the turbidity and the residual chlorine. On the Bacteriological plan, the total germs, the salmonellae, the fecal streptococci and the Escherichia coli have been identified. In addition, the monitoring of the evolution of the parameters analyzed during six weeks of storage revealed a change of the organoleptic quality that appears in the fourth week and a development of Escherichia Coli for the "pure water" exposed in the sun. This study showed, on the one hand, that these "pure water" would be unfit to the human consumption and on the other hand, their storage for a prolonged period and a high temperature affects their qualities. Les eaux conditionnées en sachet plastique, communément appelées "pure water", ont depuis quelques années, gagné la confiance du public nigérien en raison de leur faible prix, leur disponibilité, la commodité, et de la perception de qualité par les consommateurs. Ce travail étudie l’impact du stockage sur la qualité des "pure water" vendues à Niamey. Ainsi, onze parmi les douze paramètres physico-chimiques analysés ont été suivis pendant six semaines de stockage des "pure water" au soleil et à la température ambiante de laboratoire. A l’issue des résultats obtenus, les paramètres physico-chimiques sont dans les normes hormis la turbidité et le chlore résiduel. Sur le plan bactériologique, les germes totaux, les salmonelles, les streptocoques fécaux et les Escherichia colis ont été identifiés. Par ailleurs, le suivi de l’évolution des paramètres analysés pendant six semaines de stockage a révélé une altération de la qualité organoleptique qui se manifeste à la quatrième semaine et un développement des Escherichia colis pour les "pure water" exposées au soleil. Cette étude a montré, d’une part, que ces "pure water" seraient impropres à la consommation humaine et d’autre part, leur stockage pendant une période prolongée et une température élevée affecte leurs qualités.

“…The high rate of inequality with respect to water and sanitation is unimaginably high in Nigeria, with a large part of the population also depending on sachet-packed and bottled water as their primary source of drinking water (Airaodion et al, 2019). Interestingly, and post SDG implementation, the majority of the vended water (sachet-packed and bottled) have been reported to be highly contaminated with microorganisms, including coliform and pathogenic bacteria (Atuanya et al, 2016;Omonigho and Daodu, 2016;Anochie et al, 2018;Opafola et al, 2020), heavy metal and potential Endocrine Disrupting Chemicals [EDCs] (Atuanya et al, 2016;Dada et al, 2018), with EDCs being mostly reported to be more prevalent in sachet-packed water samples compared to bottled water (Dada et al, 2018). It is worthy of mention that the sachet-packed vended water samples are consumed more because of its cheap price.…”

Access to potable water is a major problem confronting most developing nations particularly with the overwhelming health burden posed by polluted water and its sources. In this review, studies on the level of contamination of drinking water sources in different geopolitical zones in Nigeria were assessed. The anthropogenic activities eliciting the pollutions were extensively discussed. Overall, the level of Nigeria preparedness in meeting the sustainable development goal number 6 (SDG no 6: to ensure availability and sustainable management of water and sanitation for all) was evaluated. Cogent methods that could enhance the achievement of SDG no. 6 were suggested. From our analysis of published literature, pre- and post- SDG implementation in Nigeria, it is clear that no significant progress has been made in providing potable water for all in Nigeria. All implementing partners must therefore rejig the process to ensure the availability of potable water, in order to achieve the sustainable development goal six.
