By taking this groundwater as the first source for drinking water it could affect human health. The aim of this research is to present solutions to prevent groundwater pollution in a sustainable way. This article presents three different approaches to tackle this problem, compares their strengths and flaws and finally points out the best solutions measured by cost, effort and sustainability.
