Abstract
The definition of background values in groundwater is an important issue for the assessment of groundwater contamination caused by local sources. The Italian Institute for Environmental Protection and Research (ISPRA) developed in 2009 the “Technical Guidelines for the evaluation of background levels of inorganic substances in groundwater”. In these Guidelines the definition of the specific geological context, the evaluation of geochemical, chemical and biological phenomena determining the diffuse presence of chemicals in groundwater, the criteria for analysis of existing data, the minimum criteria for the geological and chemical characterization of the groundwater body, the procedures for spatial assessment, statistical analysis of groundwater data and finally the selection of the representative value for background have been set. This paper describes the application of ISPRA Technical Guidelines to the large area of Portoscuso Municipality (SW Sardinia) characterized by a diffuse passive contamination due to a metallurgic industrial district.
