Valutazione dei meccanismi di degradazione dei nitrati durante il processo di infiltrazione e trasporto nelle acque sotterranee come verifica della efficacia delle misure di mitigazione della contaminazione nelle Zone Vulnerabili da Nitrati
… of strict regulations outlined in the Nitrate Directive, no noticeable improvement in groundwater quality has been observed in many Nitrates Vulnerable Zones. The study area, the plain of Arborea (Sardinia), has been identified as a NVZ since 2005, and this phenomenon is clearly …
