“…Similar observations about water-borne diseases such as diarrhoea and gastroenteritis in Africa are very common ( Oppong et al, 2020 ; Samie et al, 2020 ). Indiscriminate open defection around surface and groundwater sources in Africa have also been reported in the literature ( Elisante and Muzuka, 2016 ; Anornu et al, 2017 ; Back et al, 2018 ; Abanyie et al, 2020 ; Houéménou et al, 2020 ; Mutono et al, 2020 ; Owamah, 2020 ). Through open defecation, the carriers of the virus may unknowingly transmit it through their stool to drinking water sources, which can have a debilitating effect on consumers of such virus-contaminated water.…”

Governments across the globe are currently besieged with the novel coronavirus (COVID-19) pandemic caused by SARS-CoV-2. Although some countries have been largely affected by this pandemic, others are only slightly affected. In this regard, every government is taking precautionary measures to mitigate the adverse effects of COVID-19. SARS-CoV-2 has been detected in wastewater raising an alarm for Africa due to the poor water, sanitation, and hygiene (WASH) facilities. Also, most countries in Africa do not have resilient policies governing sanitation and water management systems, which expose them to higher risk levels for the transmission of SARS-CoV-2. Therefore, this study unearthed the likely sources and routes of SARS-CoV-2 transmission in water systems (mainly wastewater) in Africa through a holistic review of published works. This provided the opportunity to propose sustainable remedial measures, which can be extrapolated to most developing countries in the world. The principal sources and routes of potential transmission of SARS-CoV-2 in water systems are hospital sewage, waste from isolation and quarantine centres, faecal-oral transmission, contaminated surface and groundwater sources, and contaminated sewage. The envisioned overwhelming impact of these sources on the transmission of SARS-CoV-2 through water systems in Africa suggests that governments need to put stringent and sustainable measures to curtail the scourge. Hence, it is proposed that governments in Africa must put measures like improved WASH facilities and public awareness campaigns, suburbanization of wastewater treatment facilities, utilizing low-cost point-of-use water treatment systems, legally backed policy interventions, and Community-Led Total Sanitation (CLTS). SARS-CoV-2 in water systems can be inactivated and destroyed by integrating ozonation, chlorination, UV irradiation, and sodium hypochlorite in low-cost point-of-use treatment systems. These proposed sustainable remedial measures can help policymakers in Africa to effectively monitor and manage the untoward impact of SARS-CoV-2 on water systems and consequently, on the health of the general public.

“…The provision of good drinking water is becoming a huge task for the government, decision making bodies and institutions spearheading water management in nations with the increasing populace (Abubakar, 2019). Good drinking water relates to water protected from external contamination and is required for healthy living (Owamah et al, 2020;Abubakar, 2018).…”

“…Studies conducted in Nigeria revealed that several water sources are contaminated (Bamgboye et al 2020; Ibe et al 2020;Oyelami et al 2013;Zacchaeus et al 2020). However, it is sad to note that in Nigeria and many other developing nations, water consumption is from these unsafe sources (Owamah, 2020;WHO and UNICEF RADWQ, 2012). The consumption of contaminated water together with poor hygiene and sanitation has been revealed as the cause of more than a million death globally (WHO 2012).…”

Background:The study conducted a comprehensive assessment of the quality of selected groundwater sources around the liquid waste treatment plant of Ahmadu University Teaching Hospital Shika, Nigeria. Water samples were collected from four (4) hand-dug wells following standard procedures, ten (10) physicochemical parameters and seven (7) heavy metals were analyzed.Results: All the physicochemical parameters studied were within the WHO specified limits except for DO which was less and turbidity which was higher. Heavy metals were found in the all the groundwater sources that were studied. However, the concentration of some heavy metals exceeded the specified limits recommended by the World Health Organization (WHO). The heavy metal presence in the groundwater sources may be connected to human activities such as waste disposal containing these metals around the groundwater sources and liquid waste from the hospital which can may have seeped into the wells.Conclusion: By implication, this study shows that the hand-dug wells were not safe for drinking. It is recommended that wells be sited away from dumpsites and waste treatment plants and effluents from waste treatment plants should also be properly treated before their subsequent discharge into the environment. This study has generated a baseline data that will be useful in monitoring heavy metal pollution.

“…According to these studies, during the last two decades, every part of the world has documented triumphs in accessing improved drinking water (IDW), sanitation, and personal cleanliness with the sustainable development goals (SDGs). [ 9–12 ] As per the report, Sub‐Saharan Africa; Latin America, and the Caribbean; West Asia and North Africa; East Asia; and South‐East Asia had 24%, 65%, 90%, 94%, and 50% of their approaches to IDW, respectively. [ 11,13 ] Intake of polluted groundwater together with compromised hygiene and sanitary conditions are the primitive causes of million annual deaths globally.…”

The groundwater quality of Vishwamitri River Basin (VRB), Central Gujarat, is assessed to evaluate its competency to meet the agricultural and drinking standards, and to determine associated human-health risk by consumption of this groundwater, if any. The overall groundwater quality for drinking is expressed by water quality index. Various indices like sodium adsorption ratio, salinity hazard, soluble sodium percentage, magnesium adsorption ratio, and Kelly's ratio represent groundwater's agricultural suitability. A health risk assessment model is used to measure non-carcinogenic human health hazard. Results reveal that i) trace metals like lithium, manganese, molybdenum, strontium, thallium, vanadium and zinc are present in groundwater indicating contamination of groundwater by hazardous industrial and agricultural wastes; ii) groundwater of about 78% of VRB area is unsuitable for drinking; iii) positive values of Schoeller index of maximum groundwater samples indicate that ion exchange of Na + and K + with Ca 2+ and Mg 2+ is the dominant mechanism to control the quality of groundwater; iv) SAR values indicate high to very high salinity of groundwater and therefore, it is unsuitable for irrigation; and v) the health risk assessment model discloses that the risk of gastrointestinal disorder is higher in children than adults; and oral ingestion is more dangerous than dermal exposure.
