Abstract
This one-page poster provides the breakdown of scientific results of nitrogen distribution in the Thiaroye aquifer reservoir. The study also measures the effectiveness and applicability of nitrogen and oxygen isotopes content in dissolved nitrates. The method assists in identifying nitrate sources and their resulting distribution in groundwater. The Thiaroye reservoir is a shallow aquifer composed of unconsolidated Quaternary Sand; the geology of the area is registered in the general context of the senegalo-mauritanian basin.
