Groundwater pollution by chlorinated compounds is one of the most common environmental issues affecting urban areas, especially for those with a huge industrial vocation. Even if Rome is not an industrial city, this kind of contamination has been recently started to be detected in the groundwater. In order to better evaluate the presence and distri...
Chapter
Il sottosuolo cittadino è un sistema complesso e in rapida evoluzione fatto di gallerie, utenze sepolte, parcheggi e altre infrastrutture interrate che interferiscono con la naturale struttura del terreno e alterano la sua porosità e la sua conducibilità idraulica o creano barriere. Di conseguenza, la gestione delle acque sotterranee urbane pone no...

Most of the large urban areas, especially those with a strong industrial vocation, present important contamination of organohlaogenated compunds. Even in the City of Rome, although it has a very limited industrial development, some sites interested by this kind of contamination have been notified in recent years. The distribution of these sites is...

The largely invisible world of groundwater is involved in many aspects of a city life: water supply systems, sewage, surface-water features, the health of plants and trees, flood potential, and drought events. Recently, groundwater has been recognized as a cornerstone in the resilience of the cities (Tanner et al. 2009). Under this perspective, map...

The City of Rome is annually affected by flooding as a result of various important meteorological events that over the years, probably because of the ongoing climate change, are occurring more frequently and with greater intensity. This is associated with an artificial drainage network not very efficient, both for the bad state of maintenance and f...

... Some of these extractive basins were converted to sportfishing ponds. The presence of chlorinated solvents in this sector of the city is widely documented (Bonf a et al., 2017;La Vigna et al., 2019) and, even if diffuse contamination can occur, there are many "multiple point sources" of contamination (Alberti et al., 2018;Alamdar et al., 2019) previously identified by local authorities. A chemical factory producing various substances and located in this area was previously identified to be the source of groundwater contamination by PCE, TCE, 1,1 DCE, and trichloromethane. ...

... Non di rado questi esercizi si prolungano per anni (Bonfà 2015) o più precisamente per decenni (Truex et al. 2017), cosicché per adempiere agli obblighi qualitativi di legge ci si può esporre all'azzardo di un impoverimento quantitativo 17 addizionale dei serbatoi. ...
... Measuring campaigns demonstrate that the aquifers hosted in the complexes of the base sands and gravels (complexes 4b and 4d) present a very similar static level, despite being located at clearly different depths. In some cases, the level of the base gravels (at a depth of approximately 50 m below the ground [37,43]) surpasses the level of the more superficial sandy aquifer by roughly 50 cm: therefore, in this area the two complexes show a diverse piezometric head level. In the areas in which complexes 4b and 4d are in stratigraphic contact, the piezometric levels are assimilable. ...
... The groundwater effect is even more marked in the reclaimed coastal areas, where some sectors are located at a lower altitude than the sea level. If the groundwater level was not kept below the ground surface by dewatering, these areas would be always groundwater-flooded (Yin and Li 2001, Camorani et al. 2005, Temmerman et al. 2013, La Vigna et al. 2016. ...

Scale (La Vigna & Mazza, 2015) and from the Hydrogeological Map of the Lower Aniene River Basin 1:20.000 () @BULLET Data on specific site stratigraphic setting coming from existing cross sections (La , Funiciello et al., 2008) @BULLET Survey of wells about the Groundwater Monitoring Network of Rome (La Vigna et al., 2014) ...
... Each section was divided in samples 100 m long, and for each sample, the average velocity (mm/year) with the internal PSI was calculated. In addition, by means of the hydrogeological map of Rome (La Vigna et al., 2015), it was possible to relate the subsidence to the soil type and use some rainfall data in certain areas. The intention of applying Sentinel-1 data was to obtain an overview of the displacements observed along the infrastructure network and to analyze the performance of Sentinel-1 data in three areas showing major subsidence, one of which was also investigated by using Cosmo-SkyMed to deepen the analysis. ...
... New piezometric data were collected during a survey campaign , which took place between July 2014 and May 2015. The investigation was performed relying on the recently established Groundwater Monitoring Network of Rome (La Vigna et al. 2015) which is currently made up of 101 measuring points comprising wells and piezometers. This widespread hydrogeological survey included also private wells and/or piezometers located on the right bank of the Tiber River and the monitoring network of Castel Porziano Presidential Estate (Banzato et al. 2013) (Fig.2 ). ...
... Therefore, in this site, the groundwater age T coincides with MRT. From available hydrogeological maps and geological profiles [42,94] the thickness of the aquifer is, at Egeria site, of 27 m. By assuming the calculated R of 0.141 ± 0.011 m y −1 , a MRT of 96 ± 8 years is obtained from Eq. 33 (Fig. 9). ...
... I siti potenzialmente contaminati censiti nella città di Roma sono riconducibili, per tipologia di fonte, essenzialmente a due grandi categorie: la prima comprende siti inquinati da fonti localizzate e la seconda siti che presentano alterazioni di fondo di origine naturale (La Vigna et al. 2014, Preziosi et al. 2009), con l'eccezione di un certo numero di siti la cui fonte di contaminazione resta tuttora da chiarire da parte della Città Metropolitana di Roma Capitale, Ente preposto alle indagini. Con riguardo alla prima categoria, la maggior parte degli episodi di contaminazione a Roma deriva da fonti localizzate: linee di distribuzione e serbatoi interrati o fuori terra, sversamenti accidentali, abbandono di rifiuti, attività commerciali o industriali comunemente diffuse su tutto territorio urbanizzato. ...
