Abstract

Application of the \“ARA-CoSSSLs” risk analysis approach at a sub-area of a relevant Italian contaminated site F. Tatàno, M. Giavazzi & R. Trabucchi Science and Technology Faculty, University of Urbino \“Carlo Bo”, Italy Abstract This paper describes a significant case-study application of the \“ARA-CoSSSLs” risk analysis approach, which has been developed as a University research study and presented at the past \“Brownfields 2006” Conference. Specific, procedural steps have been considered for the selection of contaminants of concern, the definition of representative concentrations, and estimation of relevant modelling factors. Keywords: absolute risk analysis, application, case-study, contaminated sites. 1 Introduction Management of contaminated sites represents a relevant, environmental challenge in many industrialised countries. Within an integrated plan (at a given territorial scale: provincial, regional, national) for the identification, characterisation and final remediation of contaminated sites, the application of reliable and scientifically based absolute risk analysis criteria (as a possible category within the overall soil and groundwater quality approaches [1]) is a necessary, initial step. Referring to the Italian situation, a few years ago the national technical-scientific regulation on contaminated sites was changed, with consequential effects on the regulative application conditions for the absolute risk analysis. In fact, the old Italian Ministerial Decree \“No. 471/1999” on contaminated soil management (issued in 1999 [2]) enforced a particularly restricted regulative use of the health-sanitary absolute risk analysis [1]. On the contrary, the current (issued in 2006) Italian regulation on contaminated sites (as a part of the Legislative Decree \“No. 152/2006” [3]) reflects (in Section IV, Title V) a \“multi-tiered” approach on the quality criteria for contaminated sites,
