“…Numerous data about the arsenic contents of groundwater in the study area and its surroundings are available in the literature [5,16,17,36]. Other unpublished data were acquired by the Italian National Institute of Health (ISS), by the local water management company (Talete SpA, Viterbo, Italy), and by the regional environmental protection agency (ARPA Lazio, Rieti, Italy).…”

“…This is related to the presence of the element as a minor constituent of volcanic gases and geothermal fluids and to the leaching of rocks containing the element as a minor constituent [1][2][3][4]. The presence of arsenic in groundwater of the volcanic areas of central and southern Italy has been documented for about thirty years [5][6][7][8][9][10][11][12][13][14][15][16]. These studies show that several factors control the arsenic mobility in groundwater, such as water temperature, host-rock composition, water chemistry, and the influence of magma-derived volatiles.…”

This study concerns the occurrence of arsenic in the groundwater system of the Cimino-Vico volcanic area (central Italy), different parts of which are currently widely used for local drinking water supply and for irrigation. The system shows a complex groundwater circulation, including a continuous basal aquifer, discontinuous perched aquifers, groundwater flows at high altitude, and local interactions with rising thermal fluids. Data on arsenic contents in 250 water samples from springs and wells and in 68 samples from rock outcrops were measured and combined with already existing information. Results highlight that arsenic concentrations of groundwater are influenced by type of aquifer, groundwater flow path, arsenic content of the aquifer rocks, and interaction with fluids rising from depth. Waters circulating in the Vico volcanics, one of the prominent rock units of the area, have high concentrations of arsenic, both for the basal OPEN ACCESSWater 2015, 7 5092 and the perched aquifers. A large fraction of the waters associated with this rock unit have arsenic contents higher than 10 μg/L (82 percent for basal, 40 percent for perched). In contrast, waters circulating in the Cimino volcanics have lower arsenic contents: 30 percent of the basal and 10 percent of the perched aquifers have arsenic concentrations greater than 10 μg/L. Through an integrated approach, including leaching tests to investigate the arsenic behavior concerning the water-rock interaction and a geostatistical modeling of data, it has been possible to identify and tentatively quantify suitable water resources that have arsenic content not exceeding the quality standards for human consumption.

“…Furthermore, the few investigation that have addressed groundwater arsenic geogenic contamination in the area mostly focused on the monitoring and spatial distribution of arsenic occurrence (e.g. Achene et al, 2010;Cinti et al, 2015;Piscopo et al, 2018).…”

“…Moreover, if the operating system of water quality monitoring fails to discover arsenic, the contamination may cause heavy effects on human health: a long-term exposure to arsenic can lead to stomach pain, vomiting, diarrhea, impaired nerve function, and skin cancer (International Agency for Research on Cancer (IARC) 2004 ). Hence, over the years, the limit of arsenic concentration in drinking water has been fixed lower than 10 μg/L (European Comission 1998 ) to reduce health risk (Achene et al 2010 ). To simulate a contamination accident able to generate a concentration value in the network at least equal to the regulatory limit, a total mass of arsenic, equal to 0.5 kg, is injected in the network by the contaminated well during the hour of peak water request.…”

The positioning of quality detection points as well as the frequency of sampling is a crucial aspect for the implementation of Water Safety Plans (WSPs), which have been proposed worldwide to ensure water quality and to minimize the risk from contamination in water distribution networks (WDNs). In this regard, some international legislations and best practices about quality of drinking water suggest very fine sampling frequencies, but they do not specify where the detection points should be located in a WDN. In this paper, three different approaches, based on empiricism, optimization and topology, respectively, were applied to locate detection quality points in a WDN. The comparison highlighted that empirical approach commonly adopted by water utility practitioners is unsatisfactory. The optimization-based approach, although performing significantly better, is difficult to apply, since it requires a calibrated hydraulic model. The topological approach, based on the use of the betweenness centrality and not requiring any hydraulic information and simulation, proves to be effective, and it can be easily adopted by water utilities to identify the location for quality detection points, due to its simplicity compared with the optimization-based approach.
