Oral Topic 1 - Groundwater assessment and management Plenary

Description

Aquifer depletion and contamination are so widespread that have become a global problem. Worse, depletion causes groundwater dependent systems to suffer and loose a portion of their environmental services. Managed Aquifer Recharge (MAR) has evolved to become the only realistic remediation option, other than stopping extractions, which is often impractical. Yet, actual implementation of MAR is hindered by numerous difficulties, both technical (clogging, maintenance, etc.) and legal (inflow quality requirements are often so strict that rainfall does not meet them). We revise how to address these difficulties. Specifically, we describe the concept of a reactive layer to enhance contaminant removal process during soil passage. We conclude that MAR should, and probably will, become a conventional step of all waterworks.
