Doubt about the quality of tap water, due to its color, taste and unpleasant odors, forces a large part of the population of the city of Daloa (west-central of Cote d�Ivoire) to turn to spring and traditional wells waters whose quality is unknown. This study aims to assess the level of nitrate pollution of these shallow aquifers through 29 points including 9 spring and 20 traditional wells spread all over the city. Nitrate concentrations range from 2.5 mg/L to 301.1 mg/L, with 30% of the wells containing an excess of nitrate, beyond the WHO drinking standard (50 mg/L). The map of levels of nitrate concentrations in the city�s wells and springs shows the exposure of the populations of the old downtown neighborhoods to a high health risk due to the high pollution potential of nitrate in the water.
