CARTOGRAFIA PRELIMINARE DELLA QUALITÁ DELLE ACQUE SOTTERRANEE NELLA PROVINCIA DI ROMA (COMPRENDE DUE CARTE GEOLOGICHE)

The results concerning the elaborations of over 1800 analysis (from near 1500 sampling points) carried out between 1983 and 1998 by the Local Health Prevention Body are presented. Data were loaded in a GIS to depict an overview of the groundwater quality in the province of Rome. The relationship between baseline quality and hydrogeological complexes was evaluated. Data were classified according to the ecological status of groundwater (Dlgs 152/99) and the threshold values for drinking water (DLgs 31/2001). A preliminary evaluation of the contamination risk of groundwater was based on correlation of the actual quality vs. degree of aquifer vulnerability
