This study investigates the occurrence of iron (Fe) in the catchment area water in Nakatt from Kiffa in Mauritania. The study area was monitored during January and August. The occurrence of Fe in the groundwater showed significant spatial and temporal fluctuations. The relationship between Fe and some physicochemical parameters was also analyzed statistically using Pearson’s correlation matrix. Firstly, the results suggested that the concentration of Fe was influenced by the dissolution of Fe minerals. Secondly, the results show that the pH value was an important factor that influenced the Fe concentrations in the groundwater. The Water Quality Index (WQI) and Comprehensive Pollution Index (CPI) method was used to evaluate the suitability for human consumption. The results show that WQI and CPI are strongly influenced by Fe indicating that Fe removal would contribute to excellent well water. However, CPI also shows that the pH is a parameter to be optimized for possible potabilization. From the result of the present study, it is highly recommended that different treatment techniques should be employed to purify groundwater before consumption.

摘要

This study investigates the occurrence of iron (Fe) in the catchment area water in Nakatt from Kiffa in Mauritania. The study area was monitored during January and August. The occurrence of Fe in the groundwater showed significant spatial and temporal fluctuations. The relationship between Fe and some physicochemical parameters was also analyzed statistically using Pearson’s correlation matrix. Firstly, the results suggested that the concentration of Fe was influenced by the dissolution of Fe minerals. Secondly, the results show that the pH value was an important factor that influenced the Fe concentrations in the groundwater. The Water Quality Index (WQI) and Comprehensive Pollution Index (CPI) method was used to evaluate the suitability for human consumption. The results show that WQI and CPI are strongly influenced by Fe indicating that Fe removal would contribute to excellent well water. However, CPI also shows that the pH is a parameter to be optimized for possible potabilization. From the result of the present study, it is highly recommended that different treatment techniques should be employed to purify groundwater before consumption.
