“…In Europe, As in drinking waters represents a risk for humans in different countries like Greece, Hungary, Romania, Croatia, Serbia, Spain (Katsoyiannis et al, 2015), and Ireland (McGrory et al, 2017). Particularly, in Italy As is present in groundwater at concentrations that are above the WHO limit of 10 μg L -1 , due to geological history and substratum rock types, i.e., volcanic rocks in Central Italy and Pleistocene sedimentary rocks in Northern Italy (Mantelli et al, 1999; World Health Organization [WHO], 2001; Ungaro et al, 2008; Carraro et al, 2015; Peña Reyes et al, 2015). Specifically, in South-Eastern part of Lombardy (Po Plain) high levels of As can be measured in groundwaters characterized by low redox and oxygen content, high concentration of iron (Fe), manganese (Mn) and ammonium (NH 4 ), and by the presence of peat (Rotiroti et al, 2014, 2015).…”

“…The study was conducted on the north-facing Castelletto rock glacier (46°29’56’’N, 10°11’26’’E, Figures 1A-C ) in the Upper Valtellina valley, Italian Alps ( Calderoni et al., 1998 ). The region is part of the Austroalpine domain ( Froitzheim et al., 2008 ) and is situated between the Periadriatic and the Engadine tectonic lines ( Peña Reyes et al., 2015 ). Geomorphic surveys of the Castelletto rock glacier indicate a history comprising a glacial expansion during the Late Glacial overprinted by subsequent periglacial and slope processes ( Guglielmin et al., 1994 ; Calderoni et al., 1998 ) which then led to the deposition of slope materials and rock glacier development during the Holocene ( Calderoni et al., 1998 ; Guglielmin et al., 2004 ).…”
