Contribution to the assessment of the chemical quality from peasant wells in the city of tingrela, ivory coast

In order to contribute to the evaluation of the chemical pollution of the drinking water of the city of Tingréla and to determine the different sources of pollution, we analysed the groundwater of 11 peasant wells in different districts of the city of Tingréla. The analyses were carried out in the laboratory using the various standard techniques using a spectrophotometer and an argon plasma ionizing source mass spectrometer (ICP-MS). From the results obtained, we note the presence of major ions that cannot alter the quality of the waters studied. However, the presence of trace metal elements such as arsenic, cadmium, lead and mercury make these waters unfit for consumption. In addition, apart from natural pollution, latrines and domestic wastewater could be sources of anthropogenic pollution.
