title: Estimating river pollution from diffuse sources in the Viterbo province using the potential non-point pollution index.
abstract: This paper describes the application of the Index of Potential Non-point Pollution (PNPI) to the territory of the Viterbo Province (Central Italy). PNPI is a GIS tool that allows managers to assess the pressure on surface aquatic ecosystems deriving from diffuse sources of pollution. The index aims to assemble the available environmental datasets and specialists' expertise to set up a user-friendly and informative tool that can support decision-making processes and foster a multi-disciplinary approach. The index calculation is described and results are reported in order to give an overview of PNPI possible applications.
