Key Points
The RemTech Europe community is an important forum for discussing best practices, experiences, scientific and technological research results, and methodological approaches.
A special emphasis is placed on phytoremediation as an inexpensive and environmentally friendly tool for recovering contaminated soils, as applied using conceptual models.
Practical guidelines and operating procedures to monitor the environmental impact of human activities are reported here to guide the recovery of polluted sites.
The European experience in recovering from contamination can help other countries, in addition to learning from past mistakes.

Key Points
The results obtained during the trial indicate that the selected indigenous species are effective and can be used to remediate sediment and shallow groundwater for many CoPC in tropical climates.
If we drew a life cycle based on this study, it would be as follows: contaminants deposited to nature (soil) are extracted by plants (natural, no chemical intervention), and as the plants uptake the contaminants, they are harvested and turned into compost, which can again return to the soil (nature).
This approach can reduce contaminants in both sediment and water, and is a low-cost and environmentally friendly remediation alternative to more traditional methods.

Key Points
Assisted phytoextraction is a promising technique for the remediation of soils contaminated with potentially toxic elements.
Improving plant performance and promoting the solubility of potentially toxic elements are two critical steps for increasing the efficiency of phytoextraction.
To be considered a nature-based solution, assisted phytoextraction should be integrated into a phytomanagement strategy, to ensure not only environmental but also economic and social benefits.
There is a need for further insights into the key factors that control plant–bacteria and plant–fungi symbiosis involving native species to enhance phytoextraction.

Key Points
Continuous monitoring at the two study sites showed that the cyclic variation of VOC concentration in soil gas correlated with the variation of differential pressure and buoyancy vertical flux.
As evidenced by the differential pressure measurements conducted in this study, there is an alternation of nonemission phases, and phases in which the soil gas emission from soil to atmosphere may be enhanced due to pressure-driven advective fluxes.
The findings raise questions about the reliability of the conventional methodology employed in the collection and assessment of soil gas data.

Key Points
The research offers valuable insights that can contribute to advancing microbial electrochemical remediation systems designed to reduce Cr(VI) in water-saturated soils.
There were substantial differences from previously reported studies: acclimatization and/or adaptation and transfer of the electroactive bacterial community to Cr(VI) to a bioelectrochemical continuous flow system, no ion exchange membranes, and no nutrients and/or organic carbon added.
The research was conducted to simulate most realistically the real conditions of Cr(VI)-contaminated aquifers, in terms of solid-to-liquid ratio, interactions among soil phases, and physicochemical parameters (pH and electrical conductivity).
The outcomes achieved in the system for Cr(VI) reduction in water-saturated soil can demonstrate the feasibility of employing microbial electrochemical technology for the in situ treatment of contaminated aquifers, with interesting implications for economic and environmental sustainability.

Key Points
The Criteria for the Assessment of Environmental Damage (CAED) project developed a comprehensive CAED Toolkit aimed at simplifying the understanding of the ELD's scope and guiding operators and public authorities in responding to emissions, events, or accidents that may lead to environmental damage.

Key Points
After years of operational activity at the Capo Frasca Range (CFR), baseline environmental investigations have identified a very limited impact on soil quality, attributable to few exceedances of the screening values (SVs) for Cd, Cu, and Ni; in addition, energetic compounds were not detected.
Given the exceedance of the SVs, a site-specific health risk analysis was conducted, revealing that the concentrations of metals (Cd, Cu, and Ni) found in the soils were below the acceptable contamination levels (ACLs).
Based on the subsequent results, post-training monitoring was planned.
Compared with the international state-of-the-art, environmental monitoring in Italian military ranges exhibits obvious deficits.
