Abstract:

Environmental pollution remains one of the most serious world problems. Great efforts are made to limit the release of harmful compounds into the environment, and a variety of methods for remediation of soil, surface water, and groundwater have been developed over the years. Chemical remediation technologies are of great interest since they can remove and degrade pollutants in contaminated sites. This paper focuses on several chemical remediation technologies, such as precipitation, flocculation, adsorption and ion exchange, chemical oxidation, soil washing and flushing, and electrokinetic remediation. Remediation technologies are almost always combined one with another, although they can be used separately. Choosing an appropriate technology will depend on the type of the pollutants and site conditions, and it should be done in such a manner so that the most cost-effective and efficient technology is chosen. Even though some of the technologies are used full-scale, research should be focused on enhancing the existing, and developing new remediation technologies.

Abstract:

Nanotechnology has been widely used in many fields including in soil and groundwater remediation. Nanoremediation has emerged as an effective, rapid, and efficient technology for soil and groundwater contaminated with petroleum pollutants and heavy metals. This review provides an overview of the application of nanomaterials for environmental cleanup, such as soil and groundwater remediation. Four types of nanomaterials, namely nanoscale zero-valent iron (nZVI), carbon nanotubes (CNTs), and metallic and magnetic nanoparticles (MNPs), are presented and discussed. In addition, the potential environmental risks of the nanomaterial application in soil remediation are highlighted. Moreover, this review provides insight into the combination of nanoremediation with other remediation technologies. The study demonstrates that nZVI had been widely studied for high-efficiency environmental remediation due to its high reactivity and excellent contaminant immobilization capability. CNTs have received more attention for remediation of organic and inorganic contaminants because of their unique adsorption characteristics. Environmental remediations using metal and MNPs are also favorable due to their facile magnetic separation and unique metal-ion adsorption. The modified nZVI showed less toxicity towards soil bacteria than bare nZVI; thus, modifying or coating nZVI could reduce its ecotoxicity. The combination of nanoremediation with other remediation technology is shown to be a valuable soil remediation technique as the synergetic effects may increase the sustainability of the applied process towards green technology for soil remediation.

Abstract:

Soil is a very vital necessity to the ecosystem and human population. Due to the urbanization and industrialization, the quality and the fertility of soil is deteriorating. This has been a huge concern among countries to discover the suitable yet effective solution to remediate the soil as the contaminated soil may introduce unhealthy and unsafe environment to society. One of the common pollutants in soils are heavy metals and it is very challenging to remediate as it is not biodegradable materials. Remediation methods for metals can be classified to two categories; in-situ remediation and ex-situ remediation. Studies show that chemical remediation the most effective methods used. Chemical remediation and biological remediation are also another two available options. Chemical remediation methods can be categorized into four; chemical leaching, chemical fixation, electrokinetic remediation and vitrify technology. Biological remediation includes phytoremediation, bioremediation and the combination of the remediation are one of the most cost effective methods that can be implemented especially in poor and middle income countries as it involves natures such as plants and animals in the process

Abstract:

The application of persulfate (PS) for the remediation of petroleum hydrocarbon contamination is among the most widely employed in situ chemical oxidation (ISCO) techniques, and it has received widespread attention due to its limited impact on soil integrity. This study employed a FeSO4-activated PS oxidation method to investigate the feasibility of remediating soil contaminated with total petroleum hydrocarbons (TPHs). The factors tested included the TPH concentration, different PS:FeSO4 ratios, the reaction time for remediation, soil physical and chemical property changes before and after remediation, and the effect of soil before and after remediation on soybean growth. The TPH degradation rate in soil was highest for high-, medium-, and low-TPHs soils—81.5%, 81.4%, and 72.9%, respectively, with minimal disruption to the soil’s physicochemical properties—when PS:FeSO4 = 1:1. The remediation verification results indicated that the condition of the soybeans was optimal when PS:FeSO4 = 1:1. Under this condition, the net photosynthetic rate, stomatal conductance, intercellular CO2 concentration, and transpiration rate all remained high. Therefore, the best remediation effect was achieved with PS:FeSO4 = 1:1, which also minimized the damage to the soil and the effects on crop growth.

Abstract:

The use of pesticides presents a looming danger to the living elements of our ecological system, crops, and the well-being of our species. As an outcome, various organic contaminants pollute the soil. Different physical, chemical, and biological remediation techniques have been employed for the decontamination of pesticide-polluted soils. Remediation technology should always be affordable, on-site or in-situ, and capable of restoring the soil's natural functionality. The presence of multiple pesticides can pose challenges in effectively remediating them from the soil. The present work examines the scientific literature on the benefits and drawbacks of various existing and emerging soil remediation techniques. Customized technology choices and designs for specific site conditions enhance the effective cleanup of polluted areas. The present study, which evaluates and contrasts various technological approaches, shall serve as an invaluable tool for determining the optimal soil remediation method for a given contamination dilemma.

Abstract:

Abstract In the 21st century, with the progress and development of science and technology, the pollution of water resources has become one of the main concerns. Currently available technologies for the remediation of water pollution are mainly physical and chemical remediation, and bioremediation is used in relatively few places. This paper presents the advantages and disadvantages of phytoremediation of wastewater and the current status of the application. The existing physical remediation methods, chemical remediation methods, and then bioremediation methods of in situ and ex situ remediation are described. Phytoremediation belongs to the in situ remediation method of bioremediation, which refers to the use of green plants and their inter-root microorganisms to work together to fix or decompose pollutants. Different classifications of plants play different roles in remediation, and different kinds of plants of the same classification are applied in different environments. Compared with traditional restoration methods, phytoremediation has the advantages of lower cost, additional effect on the surrounding air and soil removal, improved soil fertility after restoration, improved local landscape, a wide range of adaptation and economic benefits, etc. However, phytoremediation technology also has its shortcomings, we should invest more scientific research efforts in the research of phytoremediation technology in the future, and combine it with practice to strengthen the application of phytoremediation in wastewater treatment and reduce the harm brought to people by polluted water resources.

Abstract:

Heavy metal pollution in soil is a significant challenge around the world, particularly cadmium (Cd) contamination. In situ phytoextraction and remediation technology, particularly focusing on Cd hyperaccumulator plants, has proven to be an effective method for cleaning Cd-contaminated agricultural lands. However, this strategy is often hindered by a long remediation cycle and low efficiency. To address these limitations, assisted phytoextraction has been proposed as a remediation strategy based on the modification of certain traits of plants or the use of different materials to enhance plant growth and increase metal absorption or bioavailability, ultimately aiming to improve the remediation efficiency of Cd hyperaccumulators. To thoroughly understand the progress of Cd hyperaccumulators in remediating Cd-polluted soils, this review article discusses the germplasm resources and assisted phytoextraction strategies for these plants, including microbial, agronomic measure, chelate, nanotechnology, and CO2-assisted phytoextraction, as well as integrated approaches. This review paper critically evaluates and analyzes the numerous approaches and the remediation potential of Cd hyperaccumulators and highlights current challenges and future research directions in this field. The goal is to provide a theoretical framework for the further development and application of Cd pollution remediation technologies in agricultural soils.

Abstract:

Heavy metal pollution is one of the most serious global environmental concerns. As a result, the current research includes an overview of technologies that are being developed for remediating or eliminating such contaminants from the environment, such as physical and chemical approaches, as well as their ineffectiveness. A wide range of minute species was discovered for their potential to tolerate, resist, accumulate and absorb heavy metals. But they all are naturally occurring species and need optimal conditions as well as a longer duration to grow. Thus, there is a need for more reliable, efficient, and productive techniques to address the issue. The use of nanoparticles for remediation has paved the way for more research in this subject and the development of useful technology to cope with problems. The evolution of technologies for heavy metal remediation, particularly cadmium, is discussed in this article because it is one of the most hazardous heavy metals that necessitates immediate attention.

Abstract:

Abstract Innovative devices and tools for exposure assessment and remediation play an integral role in preventing exposure to hazardous substances. New solutions for detecting and remediating organic, inorganic, and mixtures of contaminants can improve public health as a means of primary prevention. Using a public health prevention model, detection and remediation technologies contribute to primary prevention as tools to identify areas of high risk (e.g. contamination hotspots), to recognize hazards (bioassay tests), and to prevent exposure through contaminant cleanups. Primary prevention success is ultimately governed by the widespread acceptance of the prevention tool. And, in like fashion, detection and remediation technologies must convey technical and sustainability advantages to be adopted for use. Hence, sustainability – economic, environmental, and societal – drives innovation in detection and remediation technology. The National Institute of Health (NIH) National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program (SRP) is mandated to advance innovative detection, remediation, and toxicity screening technology development through grants to universities and small businesses. SRP recognizes the importance of fast, accurate, robust, and advanced detection technologies that allow for portable real-time, on-site characterization, monitoring, and assessment of contaminant concentration and/or toxicity. Advances in non-targeted screening, biological-based assays, passive sampling devices (PSDs), sophisticated modeling approaches, and precision-based analytical tools are making it easier to quickly identify hazardous “hotspots” and, therefore, prevent exposures. Innovation in sustainable remediation uses a variety of approaches: in situ remediation; harnessing the natural catalytic properties of biological processes (such as bioremediation and phytotechnologies); and application of novel materials science (such as nanotechnology, advanced membranes, new carbon materials, and materials reuse). Collectively, the investment in new technologies shows promise to reduce the amount and toxicity of hazardous substances in the environment. This manuscript highlights SRP funded innovative devices and tools for exposure assessment and remediation of organic, inorganic, and mixtures of contaminants with a particular focus on sustainable technologies.

Abstract:

Contaminated land is a legacy of industrial revolution as a result of rapid growth of industries. Since long back, the disposal of liquid and solid wastes on land though undesirable, has been in practice. The leachate generated out from these hazardous wastes infiltrates into the ground and causes multiple problems viz., ground water pollution, soil pollution, loss of nutrition value of soil and thereby severe damage to plantation growth, changes in the soil behavior (excessive swell/shrink) depending on the nature of waste. It also causes serious distress to the existing structures such as pavements, foundations, underground pipelines and culverts. The changes in the soil behaviour caused by ground contamination can lead to structural failures. The present paper describes various physical, chemical, biological, thermal and solidification/stabilization methods of soil and ground water remediation and their comparison on the basis of applicability, time and cost.

Abstract:

Polychlorinated biphenyls (PCBs) are the organic pollutants that of persistence, fat soluble and character such as biological toxicity, widely distributed. It also showed a highly persistent in the environment, strong enrichment and high biological toxicity, having the serious harm to human health and ecological environment. The final destination of PCBs in the environmental system is soil and sediment due to its highly distribution coefficient between sediment and water. PCBs in soil is difficult to decompose and has strong adsorption. Therefore, the detection and remediation of PCBs in soil is very critical. PCBSin soil detection technologies becoming matured at present. Such as dual column gas chromatography analysis method, GC – MS, enzyme immunoassay for PCBs detecting have been widely used. Low cost, high resolution and high accuracy detection technology has been more and more attention. For the remediation technologies of contaminated soils, chemical remediation, bioremediation technologies developed fast. Efficient, economic and environmental multiple remediation method, such as elution pretreatment on contaminated soil, combination of multiple remediation techniques are the development direction of the future. Based on the analysis on detection and remediation technologies of PCBs in soil. The principle and suitable condition of different detection methods and remediation technologies of PCBs in soil was studied in this paper. To provide technical support to remediation the PCB-contaminated soils.

Abstract:

Heavy metal pollution in soil has seriously affected the living environment of human beings. Among all heavy metal pollution, cadmium (Cd) is one of the most difficult to migrate pollutants in soil. In China, more than 11 provinces and 25 regions are rich in cadmium in the soil. At present, many researchers are looking for a proper Cd pollution remediation method. Through literature review and comparative analysis, this study summarized the main repair methods, including physical repair (digging and filling, electro kinetic remediation, frozen soil remediation technology, stabilization technology), chemical curing technology (chemical healing technology, chemical extraction), bioremediation technology (Phytoremediation technology, microbial remediation technology, animal repair technology), and joint repair (Chelating agent phytoremediation, microbial remediation). Finally, we explored the principles of these methods and compared their advantages and disadvantages. It was found that the application and selection of different treatment technologies depended on Cd rich soil area, Cd pollutant content, treatment time and other factors. In the future, the remediation of soil cadmium pollution should be scientifically selected according to the local actual situation and pay attention to the joint application of various methods.

Abstract:

In recent years, heavy metal pollution in soil has become a serious problem.

Abstract:

One of the most serious environmental issues is soil pollution. With the increase in contaminated sites, how to safely and effectively remediate these contaminated soils has become an urgent environmental problem in our country. This paper summarizes the most commonly used remediation technologies and research progress for contaminated soil in the United States and abroad, including physical remediation, chemical remediation, and bioremediation. Each repair technique has advantages and disadvantages. To get around the problems with a single method and make the most of the benefits of different remediation technologies, it was suggested that research and development of comprehensive remediation technologies for contaminated soils be stepped up.

Abstract:

Screening remediation technologies through the lens of green, low-carbon, and sustainable development is crucial for contaminated land management. To better understand the applicability of remediation technologies, this paper explored their application in China based on a survey of 643 cases. By employing coupled analysis and local spatial autocorrelation methods, this study reveals the alignment between remediation technologies and pollutants, along with their spatial distribution and clustering patterns. Specifically, the four primary remediation technologies identified were cement kiln co-processing (CKCP), chemical oxidation/reduction (CO/CR), thermal desorption (TR), and solidification and stabilization (S/S), collectively accounting for over 90% of the cases. Additionally, our findings indicated significant variation in how different pollutants respond to remediation technologies, largely attributable to the characteristics of the pollutants. We observed High–High clustering patterns for CKCP, CO/CR, TR, and S/S. These were predominantly found in Jiangsu, Chongqing, Shandong, and Guizhou for CKCP and CO/CR and in Hebei, Jiangsu, Shanghai, and Chongqing for CO/CR. TR exhibited a High–High clustering in Shanghai, as did S/S. This research contributes to reducing the economic and resource costs associated with the trial-and-error of screening contaminated soil remediation technologies, offering valuable scientific and technological guidance for contaminated land regulation.

Abstract:

In Mexico, there are 635 sites contaminated by hazardous waste, due to the fact that a few years ago there was no legislation to support and guarantee environmental protection. This led to decades of contamination of soils and bodies of water. In the following case study, landfills were identified where 1,2-dichloroethane was stored, generating contaminated soil in this location, even affecting subway water bodies. The aim of this work is to identify the technologies for the remediation of contaminated soils, taking into account the affected site, the characteristics of the residue, costs and time, in order to determine the most effective and ideal technology. The Federal Remediation Technologies Roundtable (FRTR) will be considered as the counterpart for the selection of treatment technologies, published by the Remediation Bureau. The best technology for site remediation is "Soil Vapor Extraction", being the most ideal and efficient in terms of time and cost, and generating a high impact remediation outcome. The counterpart (FRTR) is considered to be a support tool that provides the most appropriate technologies for the remediation of a contaminated site.

Abstract:

Electrokinetic remediation has, in recent years, shown great potential in remediating polluted environments. The technology can efficiently remove heavy metals, chlorophenols, polychlorinated biphenyls, phenols, trichloroethane, benzene, toluene, ethylbenzene, and xylene (BTEX) compounds and entire petroleum hydrocarbons. Electrokinetic remediation makes use of electrolysis, electroosmosis, electrophoresis, diffusion, and electromigration as the five fundamental processes in achieving decontamination of polluted environments. These five processes depend on pH swings, voltage, electrodes, and electrolytes used in the electrochemical system. To apply this technology at the field scale, it is necessary to pursue the design of effective processes with low environmental impact to meet global sustainability standards. It is, therefore, imperative to understand the roles of the fundamental processes and their interactions in achieving effective and sustainable electrokinetic remediation in order to identify cleaner alternative solutions. This paper presents an overview of different processes involved in electrokinetic remediation with a focus on the effect of pH, electrodes, surfactants, and electrolytes that are applied in the remediation of contaminated soil and how these can be combined with cleaner technologies or alternative additives to achieve sustainable electrokinetic remediation. The electrokinetic phenomenon is described, followed by an evaluation of the impact of pH, surfactants, voltage, electrodes, and electrolytes in achieving effective and sustainable remediation.

Abstract:

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.

Abstract:

Soil health is vital for ecosystem functioning, agriculture, and human well-being, yet heavy metal contamination poses significant risks to environmental and public health. This review examines various methods for removing heavy metals from contaminated soils, focusing on physical, chemical, and biological remediation techniques. Sources of contamination, including industrial activities, mining, and improper waste disposal, are discussed, alongside the environmental and health impacts of heavy metals like lead, cadmium, and mercury. Physical techniques such as soil washing and excavation effectively reduce contamination but generate secondary waste and incur high costs. Chemical methods, including soil stabilization and chemical leaching, immobilize or extract metals but may risk recontamination. Biological approaches like phytoremediation and bioremediation leverage natural processes for eco-friendly remediation, though they often require longer timescales for significant results. Emerging technologies, such as nanotechnology and biochar application, show promise for enhancing remediation efficacy. However, challenges remain, including economic constraints, regulatory inconsistencies, and the need for sustainable, long-term solutions. Future directions include integrating various remediation techniques, developing eco-friendly technologies, and emphasizing long-term monitoring to ensure the effectiveness of remediation efforts. This comprehensive overview aims to inform future research and policy development to address heavy metal contamination sustainably.

Abstract:

In recent years, the rapid development of industry and agriculture in China has led to the destruction of soil environmental quality caused by pesticides, heavy metals and other pollutants entering the soil, and the decline of crop yield and quality. Therefore, soil pollution remediation is urgent, and it is urgent to explore the remediation technologies of polluted land with good remediation effect, low cost and popularization. This paper summarizes the relevant technologies in the literature, expounds several practical measures of chemical remediation technology of polluted land in detail, and discusses the development trend of contaminated land remediation technology in the future, in order to provide theoretical support for promoting the remediation technology of polluted land in China.

Abstract:

Groundwater remediation operation involves several considerations in terms of environmental, technological and socio-economic aspects. A decision support tool (DST) becomes therefore necessary in order to manage problem complexity and to define effective groundwater remediation interventions. CCR (Credence Clearwater Revival), a decision support tool for groundwater remediation technologies assessment and selection, has been developed to help decision-makers (site owners, investors, local community representatives, environmentalists, regulators, etc.) to assess the available technologies and select the preferred remedial options. The analysis is based on technical, economical, environmental and social criteria. These criteria are ranked by all involved parties to determine their relative importance for a particular groundwater remediation project. The Multi-Criteria Decision Making (MCDM) is the core of the CCR using the PROMETHEE II algorithm.

Increasing the diversity of technologies used to remediate contaminated soils and groundwater is one of the goals of EPA's Office of Solid Waste and Emergency Response (OSWER). While conventional methods of waste remediation, such as stabilization, containment, and incineration, are certainly valid approaches to resolving waste problems, statutory and economic considerations are now, more than ever, encouraging the entire remediation community to consider change in thinking and practice.

Abstract:

Petroleum hydrocarbon spill on land pollutes soil and reduces its ecosystem. Hydrocarbon transport in the soil is aided by several biological, physical, and chemical processes. However, pore characteristics play a major role in the distribution within the soil matrix. Restoring land use after spills necessitates remediation using cost-effective technologies. Several remediation technologies have been demonstrated at different scales, and research is ongoing to improve their performances towards the reduction of treatment costs. The process of removing the contaminants in the soil is through one or a combination of containment, separation, and degradation methods under the influence of biological, physical, chemical, and electrically-dominated processes. Generally, performance improvement is achieved through the introduction of products/materials and/or energy. Nevertheless, the technologies can be categorized based on effectiveness period as short, medium, and long term. The treatment cost of short, medium, and long-term technologies are usually in the range of $39 – 331/t (/tonne), $22 – 131/t, and $8 – 131/t, respectively. However, the total cost depends on other factors such as site location, capital cost, and permitting. This review compiles cost-saving strategies reported for different techniques used in remediating petroleum hydrocarbon polluted soil. We discuss the principles of contaminant removal, performance enhancing methods, and the cost-effectiveness analysis of selected technologies.

Abstract:

Heavy metals, such as lead, chromium, zinc, cadmium and cooper may cause hazardous harm to human health and the environment because of their dissolubility and mobility. Selection of the most appropriate soil remediation method depends on site characteristics, concentration, types of pollutants to be removed and the final use of a contaminated medium. This paper reviews soil remediation technologies, such as isolation and containment, solidification/ stabilization technologies, soil washing and flushing technologies, electrokinetics and phytoremediation.

Abstract:

Groundwater contamination is one of the most concerning issues from uranium mining activities. Radionuclides cannot be destroyed or degraded, unlike some organic contaminants (and similar to metals). Besides, sites, where radionuclides may be found, are mainly radioactive and mixed waste disposal areas, and therefore many other contaminants may also be present in groundwater. The state-of-the-art of environmental technology is continually changing, and thus a review on technologies application is of utmost relevance. This work gives an overview of the available remediation technologies for groundwater contaminated with radionuclides resulting mainly from uranium mining. For each technology, a theoretical background is provided; the state of development, limitations, efficiency, and potential adverse effects are also approached. Examples of application and performance monitoring of remediation progress are described, and criteria for the selection of the appropriate remediation technology are given. The most effective remediation technology will always be site-specific as a result of the multitude of geographic and operational factors that influence the effluent quality and impact the technical feasibility of treatment methods. Ion exchange, chemical precipitation, and membrane filtration have been considered by the U.S. Environmental Protection Agency (US EPA) as best demonstrated available technologies for radium and uranium removal. Several factors have been demonstrated to influence the selection of a remediation technology (technological aspects and non-technical factors), but even for the technologies demonstrated or industrial proven, two important challenges remain; the (still) mobile radionuclides and the generation of secondary wastes. Besides, remediation technologies are constantly evolving, but future advancement depends on rigorously monitored, documented efficiency, and results achieved. Therefore, the technologies approached in this paper are by no means exhaustive.
