Assessment of Groundwater Contamination Risk from Landfill Site Using HELP and SESOIL Models: A Case Study from Jordan

Problem Description / Relevance to Water Security: 

Leachate is the liquid generated in landfills as a result of dumping the solid waste. It consists of the juice resulting from the moisture contained in the solid waste plus the rainwater that penetrates through the solid waste matrix. Al-Akeeder landfill is unsanitary landfill that does not contain leachate control and management system. Therefore, there is a chance that leachate which has a high contamination potential can reach to both surface and groundwater bodies and rendering them contaminated.

ICT Application / Outcome: 

The primary goal of the study is to estimate the leachate quantity generated from Al Akeeder landfill, to study the transport of nitrate from leachate to the subsurface soil layers and to assess the risk associated with Al Akeeder landfill leachate to the groundwater at the site. Figure 1 outlines the procedures followed to perform these tasks.
