ABSTRACT
MAR, previously known as articial recharge, is the purposeful recharge of water to aquifers for reuse and/or environmental benet. Aquifers are permeable geological strata that contain water and are replenished naturally by rain permeating through soil and rock to the aquifer below or by inltration from streams. However, several human activities may enhance aquifer recharge, which can generally be put into three categories:
1. Unintentional Recharge: Such as through land clearing, removing deep-rooted vegetation, deep seepage under irrigation areas and in urban areas by leaks from water infrastructure and sewers, for example, Tula Valley, Mexico [13].
