Assessment of landfills leachate impacts on groundwater quality with considering some case studies around the world

Nowadays with developing of all parts of human society such as industries, irrigations, cities, etc., the need for fresh water is increasing. There are lots of pollution sources that affect our fresh water resources. In order to have sustainable development and save our fresh water resources for current and future generations, we have to monitor steadily our projects and environments to preserve our water resources from pollution sources. In this thesis, I have general overview on pollutions come from landfills and municipal wastes to our groundwater resources around the world and how we can preserve our resources from pollutions with using of some approaches that come in directives. In order to summarize this research, in the first step, I will discuss about groundwater definition in academic literatures and its different aspects, the importance of it as fresh water resources to cities, industries and agricultural users and. Then I will discuss about different parameters and elements which are caused pollution on groundwater resources. After, I will introduce some landfill case studies around the world. Finally, I will provide some criteria which are prevented our groundwater resources from different pollutions with using of some directives and rules.
