Sierra Leone experiences a high amount of rainfall, which goes into storage in the subsurface to build up the groundwater potential in the country. In Pepel, in the northern region of Sierra Leone, the majority of the population depends on groundwater for domestic and other purposes. Even though there is a high potential for groundwater, there is still a serious problem with adequate availability and quality of groundwater. The objective of this research is to determine how the presences of NO3- and SO-4 influence the lowering of pH of the water.
