Nitrate contamination of groundwater is increasing on a worldwide scale, due, principally, to the high use of fertilizers, to the leaking from the sewage network and to the presence of old septic systems.

Abstract

Nitrate contamination of groundwater is increasing on a worldwide scale, due, principally, to the high use of fertilizers, to the leaking from the sewage network and to the presence of old septic systems. The research reported herein presents a method for groundwater contamination risk assessment based on a previous experience of the author in terms of nitrate risk evaluation (DUCCI et al. 2007). This paper starts from a definition of the GIS layers used for the application of the method based on the geo-indicators. Afterward, the protocol to overlap the layers and the weight of these is explained. The methodology is applied in a large flat area of southern Italy, with, in a wide sector, very high concentrations in NO3.
