“…In addition, the behavior of the aggregates has not yet been defined, since in some cases the soils are repellent but not in all of them (Hewelke and Gozdowski, 2020). Recently, it was found that these effects could depend on the stability of the aggregates and, that in old spills, this phenomenon could favor the elimination, deposition or washing of contaminants (Gautam et al, 2020).…”

“…Decrease in water and nutrient holding capacities [24,25] Chemical Loss of soil organic matter, cation exchange capacity, microand macronutrients [26][27][28] Increase in bioavailability and mobility of residual pollutants [29,30] Toxicity of residual extractants [23,31,32] Biological Changes in DNA content and microbial population structure Reduced enzyme activities Reduced germination and growth rates of plants (crops) [24,27,33,34] The physical separation process involves reducing the volume of contaminated soil by utilizing physical properties to separate ordinary particles from particles where pollutants are concentrated. Gautam et al [25] suggested that finer soils (particle diameters < 0.075 mm) act as degrading media during SW and should be separated after washing all of the soil. Fine soil particles that contain a high concentration of contaminants are separated for further treatment or disposal [26].…”

Global governance of soil resources as well as revitalizations and remediation of degraded areas seem to be necessary actions for sustainable development. A great deal of effort has gone into developing remediation technologies to remove or reduce the impact of these contaminants in the environment. However, contaminated soil remediations in stringent conditions deteriorate soil properties and functions and create the need for efficient soil revitalization measures. Soil washing (SW) and thermal desorption (TD) are commonly used to remediate contaminated soil and can significantly reduce the contaminant, sometimes to safe levels where reuse can be considered; however, the effects of treatment on soil quality must be understood in order to support redevelopment after remediation. In this review, we discussed the effects of SW and TD on soil properties, including subsequent soil quality and health. Furthermore, the importance of these techniques for remediation and reclamation strategies was discussed. Some restoration strategies were also proposed for the recovery of soil quality. In addition, remediated and revitalized soil can be reused for various purposes, which can be accepted as an implementation of sustainable remediation. This review concludes with an outlook of future research efforts that will further shift SW and TD toward sustainable remediation.

“…Therefore, a suitable remediation technology for Cr(VI)-contaminated soils is urgently needed. Soil washing, 8 chemical reduction, 9 electrokinetic remediation, 10 and biological methods 11,12 are the main treatments for Cr(VI)contaminated soils. Among them, chemical reduction is widely used in full-scale soil remediation because of its advantages of efficient and simple operation.…”

In this study, a cost‐effective and eco‐friendly method was developed to remediate soil contaminated by hexavalent chromium (Cr[VI]) using ferrous sulfate and biogas residue (BR). The results show that the addition of BR at mole ratio of Fe(II)/Cr(VI) = 3:1 and mass ratio of BR (dry mass)/Cr(VI) = 70:1 significantly improved the reduction of Cr(VI) and reduced its mobility. Moreover, the reduction efficiency of Cr(VI) was higher than 85% at day 1 and reached a maximum of 96.7% at day 7. The X‐ray photoelectron spectroscopy, scanning electron microscopy, and microbial diversity analyses indicated that the microbial mechanism created by the BR addition was crucial for the long‐term and stable reduction of Cr(VI). The enriched Cr(VI)‐reducing bacteria genera in the BR directly reduced Cr(VI), whereas the reducing bacteria in the BR indirectly reduced Cr(VI) to Cr(III) through the electron transport system in the reaction system. The addition of BR can lead to a high reduction efficiency and long‐term stabilization of Cr(VI)‐contaminated soils. This study provides reference values for the combined remediation technology for Cr(VI)‐contaminated soils.
