摘要: In the last years, because of uncontrolled human activities, a significant increase groundwater pollution occurred worldwide, with nitrate being among most widespread pollutants. The assessment vulnerability represents an important tool for developing quality plans and in delimitation “Nitrate Vulnerable Zones”. this study, three rating methods (DRASTIC, SINTACS GOD) were applied alluvial plain to check reliability results comparing obtained thematic maps observed concentrations groundwater. Results show that without large modifications specific vulnerability, these methodologies cannot describe actual distribution study area. A new easy methodology called Protection from Natural Anthropogenic sources (PNA) was then defined tested. PNA map divides area five classes very low high shows fair correlation concentrations. selection parameters algorithm makes strongly flexible applicable similar watersheds around world, as delineation
