“…These results suggest that these two forms of chromium can coexist in water in detectable amounts solely for the limited range −30 ≤ log f O 2 ≤ −20 (corresponding to the conditions characterizing the transition from shallow groundwater to deeper hydraulic circuits leading to more evolved Ca ‐enriched waters; see also Fantoni et al, ; Lelli et al, ) and the relative proportions of Cr (III) and Cr (VI) within this region is sensitive to log f O 2 . Otherwise, the role of log f O 2 is no longer relevant for the chromium valence state partitioning for −20 ≤ log f O 2 ≤ −0.67 (a setting ascribed to shallow groundwater circulation leading to Mg ‐ HCO3 rich waters; see also Fantoni et al, ; Lelli et al, ) and the total amount of chromium is found in the form of Cr (VI) .…”

“…Our approach relies on the following steps (see Text S1 and Figures S1–S2 for more details): We select the intervals of variation listed in Table for the three uncertain inputs on the basis of literature analysis (Fantoni et al, ; Helgeson et al, ; Lelli et al, ). Note that we consider f O2 to vary between its value in free atmosphere and very low values that may be associated with deep water circuits.…”

“…The relevance of the setting considered is supported by the observation that nonnegligible concentrations of dissolved Cr (VI) in groundwater bodies are documented in diverse geographical regions. For example, alarming concentrations of Cr (VI) are registered in Countries such as Italy, United States (California), Greece, Mexico, Japan, Indonesia, Brazil, and Australia (e.g., Apollaro et al, 2011;Bourotte et al, 2009;Fantoni et al, 2002;Gray, 2003;Kaprara et al, 2015;Kazakis et al, 2015Kazakis et al, , 2017Lelli et al, 2013;Mills et al, 2011;Morrill et al, 2013;Robles-Camacho & Armienta, 2000;Saputro et al, 2014). It is now well established that the presence of Cr (VI) in natural waters can be linked to anthropogenic pollution and/or geogenic origins.…”

We focus on the joint application of local and global sensitivity analyses to characterize propagation of model parameter uncertainties to outputs of subsurface water geochemical models. The latter typically involve uncertain inputs, including environmental conditions, mineral rock composition, and flow/transport features. In this context, implementation of sensitivity analysis techniques enables us to grasp the relative role of each model input. Here we focus on the application of several sensitivity approaches to the assessment of Cr (VI) geogenic leakage due to water‐rock interactions. We specifically target the impact of uncertain environmental conditions on the chemical composition of spring waters following water transfer through a host rock system with given mineral composition. We employ a reaction path modeling approach and represent uncertainties of environmental conditions through three parameters, that is, oxygen fugacity (fO2), CO2 fugacity (fCO2), and temperature, which we consider as random quantities. We consider three diverse methodologies, that is, (a) the Scatter Plots sensitivity analysis, (b) the Distributed Evaluation of Local Sensitivity Analysis, and (c) a moment‐based global sensitivity analysis. Our results suggest that (a) the relative importance of a given model parameter in driving the uncertainty of the spring water composition may display remarkable variations across the sampled parameter space and (b) parameter ranking through sensitivity metrics for geochemical applications in subsurface water resources requires a joint assessment of local and global sensitivity.

“…Sampling of water and sediments from both the Cecina River and from wells located in the coastal area were analyzed [14][15][16][17]. Pollutants bioaccumulation was also assessed in fresh water fish caught in the Cecina River [14]. Quality of the sea and groundwater was evaluated according to criteria settled by Italian national law (DM 260/2010) [19].…”

“…High levels of chromium, arsenic and nickel were found in mussels gathered in front of Rosignano Marittimo [13]. As far as groundwater pollution is concerned, high levels of chromium (of natural origin) [14], organic nitrates (due to the use of organic fertilizers) [17], boron and mercury [15,16] (both released by chemical and geothermal plants situated in the upper course of the river) were found in water and sediments of the Cecina River basin. Elevated organic mercury concentrations were also documented in several fish species caught in the river (particularly in eels -Anguilla anguilla) [15].…”

Objectives: Environmental pollution is associated with morbidity and mortality for chronic-degenerative diseases. Recent data points out a relationship between proximity to industrial plants and mortality due to neoplasms. The aim of this study has been to compare mortality due to chronic-degenerative diseases in the area of Tuscany (Bassa Val di Cecina), Italy, characterized by the presence of 2 neighboring municipalities similar in terms of size but with substantial differences in industrial activities: Rosignano (the site of chemical, energy production and waste processing industries) and Cecina (with no polluting activity). Material and Methods: Standardized mortality rates for the 2001-2010 decade were calculated; the data of the whole Tuscany was assumed as reference. Environmental levels of pollutants were obtained by databases of the Environmental Protection Agency of Tuscany Region (Agenzia Regionale per la Protezione Ambientale della Toscana -ARPAT). Maximum tolerated pollutant levels set by national laws were assumed as reference. Results: In the whole Bassa Val di Cecina, significantly elevated standardized mortality rates due to mesothelioma, ischemic heart diseases, cerebrovascular diseases and Alzheimer and other degenerative diseases of nervous system were observed. In the municipality of Rosignano, a significant excess of mortality for all these groups of diseases was confirmed. On the contrary, the municipality of Cecina showed only significantly higher mortality rates for ischemic heart diseases. Elevated levels of heavy metals
