Manuscript Info Abstract ……………………. ……………………………………………………………… Manuscript History Received: 22 October 2024 Final Accepted: 25 November 2024 Published: December 2024 Key words:- Heavy Metals, Natural Springs, Traditional Wells, Quality Index, Hazard Quotient The water provided by the public network in the city ofDaloa is rejected by residents because of the disagreeable organoleptic characteristics. This situation has pushed a large, proportion of the population to exploit the water from resurgent springs and traditional wells. However, these waters tap into alterite aquifers, which are the first reservoir to receive seepage water that is often highly laden with impurities. As a result, these waters could be contaminated by domestic and industrial effluents, deteriorating their quality and impacting consumer health. Hence the need to evaluate the health risk from these waters. To this end, seasonal analyses of physico-chemical parameters on 40 waters points have been carried out. Methodological approach consisted of using the water quality index and the probabilistic risk method. As a result, these waters are rich in heavy metals whatever the season, and the quality varies from very poor to good for wells and from poor to good for springs. Thus, the chromium VI-related health risk for these waters in both seasons has a hazard quotient greater than 1. The level of carcinogenic risk is also very high, with a value greater than 10 -4 . People are therefore exposed to gastrointestinal risks and can contract cancer when they consume untreated well and spring water. Copyright, IJAR, 2024,.

Introduction:- The problem of human health, in different parts of the world, is closely associated with environmental and groundwater pollution (Adimalla et al., 2018 ; Babuji et al., 2023). Speaking of groundwater contamination by physicochemical substances, it is a very important concern in the current century (Babuji et al., 2023 ; Rajan et al., 2024). These concerns are widespread throughout the world, because water pollution affects people's health and well-being. In fact, ingesting contaminated water causes serious problems for human health (Ramos et al., 2023). This is the case for metals, which have various impacts on health, such as cancers, respiratory diseases, gastrointestinal disorders and skin allergies (Mawari et al., 2022). And, according to the WHO (2017), more than 1,1 million children under the age of 5 and the elderly, who live where hygiene measures and sanitation systems are inadequate, die each year from diarrhoeal diseases, of which 90% are due to the poor quality of the drinking water. This problem affects developing countries enormously, especially urban areas, where rapid population growth, lack of adequate sanitation, industrial operations and climatic variations influence the quality of groundwater resources used for human consumption (Mendieta-Mendoza et al., 2021 ; Babuji et al., 2023).
