[The renewability of the groundwater resource in clean-up interventions: legal assumptions and technical implications of environmental sustainability]

[This Technical Note highlights some legal aspects and technical principles closely related to the concept of ground water renewability, in as far as this concept is considered when designing and implementing environmental clean-up projects and works. After outlining the quantitative importance of groundwater in meeting Italian water demand, some key points of the current regulations are commented on, and some practical guidelines are proposed which could be adopted during remediation of groundwater at contaminated sites, aiming at the protection and qualitative-quantitative restoration of the aquifers as an indication of sustainability].
