Mining produces significant amounts of solid mineral waste. Mine waste storage facilities are often challenging to manage and may cause environmental problems. Mining waste is often linked to contaminated mine drainage, including acidic waters with more or less elevated concentrations of trace metals such as lead. This work presents a study on the mobilization of lead from waste from two typical mining sites: Zeida and Mibladen, two now-closed former Pb–Zn mines in the Moulouya region of Morocco. Our research investigates the mobilization potential of Pb from the waste of these mines. The study involved acid–base neutralization capacity tests (ANC–BNC) combined with geochemical modeling. Experimental data allowed for the quantification of the buffering capacity of the samples and the mobilization rates of lead as a function of pH. The geochemical model was fitted to experimental results with thermodynamic considerations. The geochemical model allowed for the identification of the mineral phases involved in providing the buffering capacity of carbonated mining waste (Mibladen) and the meager buffering capacity of the silicate mining waste (Zeida). These cases are representative of contaminated neutral drainage (CND) and acid mine drainage (AMD), respectively. The results highlight the consistency between the ANC–BNC experimental data and the associated modeling in terms of geochemical behavior, validating the approach and identifying the main mechanisms involved. The modeling approach identifies the dissolution of the main solid phases, which impact the pH and the speciation of lead as a function of the pH. This innovative approach, combining ANC–BNC experiments and geochemical modeling, allowed for the accurate identification of mineral phases and surface complexation phenomena, which control the release of lead and its speciation in drainage solutions, as well as within solid phases, as a function of pH.

Background. Three villages in Yunnan Province were identified to have abandoned arsenic mines severely contaminating the local water supplies. Other villages in the Province had similar problems causing the Yunnan Environmental Protection Bureau (YEPB) to seek assistance in developing a remedial strategy. Objectives. Identify the immediate hazards, develop practical remedial approaches, with focus on human health impacts associated with contaminated drinking water. Develop a blueprint for dealing with other isolated mine pollution problems in the mountains of Yunnan. Materials & Methods. A technical team from Blacksmith Institute, TerraGraphics Environmental Engineering and Yunnan Environmental Protection Bureau (YEPB) visited the sites and conducted environmental sampling. TerraGraphics prepared a technical review of each site, a discussion of human health risks and objectives for remedial actions, using United States Environmental Protection Agency (USEPA) guidance for waste site evaluations. From the recommended interventions for each site, YEPB selected a site for construction remediation. Results. Samples of wastes, soils and water indicated high metals contamination at all three sites. The closed arsenic refinery in Wenshan County was selected for a demonstration cleanup project. Subsequent analyses showed significant improvements in metals levels and achievement of remedial objectives. The site is recognized as a model for other mining sites in Yunnan. Conclusions. The success of the demonstration project was recognized and has provided direction and momentum for a wider effort by the Province to address mining pollution and water contamination challenges. It demonstrates the success of using known techniques for environmental remediation in the US, with local partners in China responding to their communities' health and environmental problems.

How does climate change affect the politics of military bases? The United States alone has hundreds of overseas bases that require continuous coordination with host governments. I argue that climate change can create knock-on environmental problems associated with a base’s infrastructure or waste. Those knock-on problems create a mix of subnational, international, and transnational political contestation that raises the political costs of overseas bases and could even rupture an international relationship. I probe the plausibility of the theoretical framework using new evidence from Greenland. Between 1953 and 1967, the US Army maintained secret bases in Greenland as precursors for a nuclear ballistic missile complex. The bases were eventually abandoned, leaving considerable waste behind. Climate change is now poised to remobilize these pollutants into the surface water, creating a risk for human settlements. The case could be the proverbial canary in the coal mine for future politics surrounding overseas military bases.

Internationally it has become recognised that diffuse source water pollution from mining activities severely affects the degradation of water quality especially with regards to acidification and metal loading. South Africa is facing major problems with regard to the management and treatment of contaminated mine water. Very little has been published for South Africa about the quantities and qualities of diffuse source water pollution by the mining industry. Furthermore the available information has not yet been compiled into a consolidated overview that presents the total picture. Some of the problems that limit the use of the available information and would necessitate further processing to normalise the data, derive from the fact that the investigations producing the information were done at different times, to different levels of detail and using different approaches. A further complicating factor is that data for some mining commodities may not be available and may necessitate further investigation. The overview of the quantities and qualities of non-point source effluent production by different sectors needs to be interpreted in terms of the effect the effluent can be expected to have on receiving water quality (both surface and groundwater). It would thus be necessary to categorise waste types according to their effect on water quality and synthesise the data to obtain an estimate of the threat that different sectors and sub-sectors pose to receiving water quality.

A study on sorption of heavy metal ions: Lead (Pb2+), Copper (Cu2+) and Cadmium (Cd2+) from mine wastewater by activated carbons prepared from coconut husk was conducted. The activated carbons were prepared by carbonisation of the husk at 900 ºC pyrolysis temperature, followed by steam activation of the pyrolysis derived char. Activation was also performed at 900 ºC for various durations at steam addition rate of 0.2 mol/h/g in a Gas Fired Static Bed Pyrolysis-Activation Reactor. The derived activated carbons were contacted with mine wastewater containing heavy metal ions to assess their heavy metal ions adsorption potential. The results show that the activated carbons efficiently adsorbed the heavy metal ions from solution, reducing concentrations of Pb2+, Cu2+ and Cd2+ from 1.56 mg/L, 1.87 mg/L and 0.69 mg/L respectively to below Ghana Environmental Protection Agency (GEPA) standards of 0.10 mg/L, 1.30 mg/L and 0.03 mg/L for Pb2+, Cu2+ and Cd2+ respectively. The significances of this study are that, the conversion of the coconut husk to activated carbons provides a solution to environmental problems associated with dumping of the waste and also provides valuable products capable of reducing the effects of heavy metals in wastewater. Keywords: Coconut Husk, Activated Carbon, Heavy Metal, Adsorption

The technological processes of coal mining, enrichment and use, in particular coal combusting is accompanied by formation and release of significant amounts of dust and gases. Atmospheric air protection is one of the most urgent problems of the nowadays technological society, as scientific and technological progress and expansion of production is associated with an increase in negative anthropogenic impacts on the atmosphere. The paper presents a new solution to the current scientific problem of reducing carbon-containing dust content based on the disclosure of the laws of the aerodynamic interaction of dust and water flows in gravitational and electrostatic fields. The authors show in this study the causes of atmosphere pollution with coal-containing dust; main issues of atmospheric air protection at enterprises located in the controlled territory of Ukraine. The data of the first quarter of the 2020 year are presented in the research. The biggest part of the facilities that pollute the atmospheric air are focused in Donetsk and Lugansk regions. It is estimated that the air environment of the underground mine surface complex is filled with exhaust ventilation air of approximately 200.000 m3 per minute with a dust concentration of approximately (5-7) mg / m3, which is equal to 1.5 tons of dust per a day. It is here that the possibility of transporting pollutants over long distances is most often realized. Coarse dust discharged through the ventilation systems of mines is intensively deposited in the sanitary protection zones of mines. Fine dust is carried by the wind outside them, polluting the environment on the distance of up to 3500 m from the coal mine. Emissions of carbon dust into the atmosphere are almost always a major part of transboundary environmental pollution. Mine waste also poses an environmental threat. Technologies of reduction air pollution at the source of carbon-containing dust formation should be used in all new industries of economy. The results obtained reveal the mechanism of interaction of the sprayed liquid with coal dust and can be used in the development of new effective means of controlling the carbon-containing dust. The principles and practices of sustainable development, coupled with local research, will help to contain or eliminate health and environmental risks resulting from air pollution by carbon-containing dust.

The search for unconventional energy resources such as coalbed methane (CBM) is on the rise in Poland due to the demand for energy resources and protection of the environment. CBM production has a lower impact on the environment when compared with coal production. Its development is known to be cost effective due to its use of shallow depths with large gas quantities. Sand is one of the by-products (waste) from open-pit mining operations. Conventional disposal of this material is achieved by storage in heaps and its deployment as landfill as well as filling material for mine pits. This paper investigates the potential use of sand (filler) as a proppant for hydraulic fracturing in coalbed methane formations in Poland through crush test measurements in both single and cyclic loadings. The crush test helps to identify proppant strength under various load applications. Test results show that the sand qualifies for the 4 K (maximum allowable stress is 27.58 MPa) and 3 K (maximum allowable stress 20.68 MPa) crush classifications under single and cyclic conditions, respectively. This finding shows the viability and potential of the investigated sand as a proppant for hydraulic fracturing in shallow coalbed methane formations in Poland. Furthermore, its use could help filler-providing companies to maintain their production level and save jobs. Notably, it would contribute to the reduction of environmental problems associated with the management of waste, such as that from open-pit mining operations.

Tailings are ground rock particles from which the valuable minerals or metals have been extracted. An historical overview on hard rock mines shows that since the 1930s, it has become current practice to pump the tailings into storage areas circumscribed by dykes made of the tailings themselves. However, numerous physical and chemical stability problems were observed mainly owing to the particular hydrogeotechnical and mineralogical properties of the tailings. Therefore, modifications to the conventional methods were proposed, but these were relatively costly, not always efficient, and sometimes difficult to implement. New management methods that improve the physical and (or) chemical stability have hence been developed to reduce environmental risks associated with tailings storage, namely, densified tailings, environmental desulphurization, covers built with tailings, and co-disposal of tailings and waste rock. Even if many aspects need to be optimized, these approaches can be considered today as interesting alternatives to conventional tailings management approaches.

The main environmental problems associated with the mining activities are related to the production of large amounts of wastes; Different pathways are responsible for heavy metals dispersion, by air due to wind action, by water mediated by acid mine drainage and erosion, and the metals could be mobilized in the soil by different transport mechanisms. Different remediation alternatives have been studied and reported in literature. In situ stabilization is a cheaper method. The heavy metals stabilization enables the decrease of metal mobility, reactivity and toxicity in the soil, decreasing heavy metals availability and phytoavailability. Sulphate reducing bacteria (SRB) have been successfully utilized in groundwater bioprecipitation of heavy metals. In this study, this biological agent has been used in the immobilization of heavy metal in the subsurface of the soil due to its dissimilative metabolism. SRB produces hydrogen sulfide that reacts with soluble metals present in the media, generating as final product low soluble metal compounds (metal sulfides). The bio-stabilization was studied at pilot scale to determine the stabilization efficiency using biological agent, SRB. The metals studied were Fe, Cu, Pb and Zn in the contaminated smelter soil. Bioaugmentation and biomagnification were applied. After 4 months, the metal stabilization efficiency was determined by leaching with acid solution at different pH to stimulate the metal mobility. The remediation pilot scale system showed that copper, lead and iron were much more stable at pH 3.0, with only 3.7% and 1% of total metal eluted, and compared with the system without biological agent. In the case of zinc, the elution was similar with or without remediation. The metal stabilization using biological agent was successful in the contaminated smelter soil and these results are promising antecedents for full scale in situ remediation strategy.

Abstract Exploitation of coal deposits in Upper Silesia is associated with production of large quantities of waste deposited at dumps. The tested samples from five dumps showed different radioactivity from each other. Radioactivity measurements made it possible to analyze the degree of risk with the factors specified by UNSCEAR such as radium equivalent activity Raeq, internal Ein and external Eex occupancy factor. There is a raised level of radiation in dumps as compared with outside dump areas. In the study area, however, there is no risk associated with elevated levels of radiation in relation to standards established by the Council of Ministers of the ionizing radiation dose limits.

The research outlined in this thesis is concerned with the environmental aspects of groundwater re-establishment as a consequence of surface mining. No principal effects which have been identified as being detrimental to the restored land area are as follows; i). The vertical and horizontal displacements of backfill materials following restoration, and ii). The pollution of groundwater from contact with weathered rockfill materials. The research into settlement has attempted to classify the types of movement which may occur within a backfill mass, in particular the differential movements which are of great importance to the stability of proposed structures or surface drainage. The field results from 10 opencast mine sites are presented, 3 of which were instrumented for detailed field investigations. It has been shown that backfill movements do not necessarily show similar trends under similar conditions, and reasons for this are proposed. A variety of instrumentation schemes have been devised to examine backfill displacements, both vertically and horizontally. Permeability testing has been conducted at different horizons the backfill mass in order to locate the zones of collapse settlement due to groundwater recovery. A critical review of the instrumentation utilised in the investigations is presented, with suggestions for improvement. Investigations into groundwater pollution have been devoted to examining the qualities of groundwater flowing into British surface mines and evaluating its likely reactions with fill materials. An insight into general groundwater pollution and treatment techniques is presented together with a critical analysis of their applicability, to British conditions. An investigation into water qualities in each of the six geographical regions of the opencast mining industry of Great Britain is detailed. Finally some suggestions for future research areas are indicated.

[Truncated abstract] Establishment of vegetation and ecosystem functioning is central to the mitigation of environmental impacts associated with mining operations. This study investigated the ecophysiological functioning of mature plants in natural vegetation and applied this knowledge to diagnose problems affecting plant health and causes of poor plant cover at a mine-rehabilitation site. Ecophysiological parameters, including plant water relations and mineral nutrition, were studied in conjunction with soil physical, hydraulic and chemical properties. The natural ecosystem at the study location in the Great Sandy Desert is characterised by sand dunes and interdunes with distinct plant communities on each. One of the most notable features of the vegetation is the presence of large Corymbia chippendalei trees high on the dunes and relatively small scattered shrubs in the interdunes. Triodia grasses (spinifex), dominate the vegetation in both habitats but different species occur in each; T. schinzii is restricted entirely to the dunes, and T. basedowii occurs only in the interdunes. It was hypothesised that the deep sandy dunes afford greater water availability but lower nutrient supply to plants in this habitat compared with those occurring in the lower landscape position of the interdunes. Water-relations parameters (leaf water potentials, stomatal conductance, d13C) revealed that dune plants, particularly woody species, displayed higher water status and water use than closely related and often congeneric plants in the interdunes. Nutrient concentrations in soils were significantly higher in the interdunes, but concentrations in foliage were similar for related species between habitats. It is concluded that the dunes provide a greater store of accessible water than the soil profile in the interdunes. ... Following an experimental wetting pulse equivalent to a summer cyclone event, A. ancistrocarpa plants displayed significant increases in stomatal conductance, leaf water potential and sap velocity in lateral roots within three days of irrigation at the natural site and two days at the rehabilitation site. Secondary sinker roots originating from distal sections of lateral roots were evidently supplying water to maintain hydraulic function in laterals, thus enabling a fast pulse response. This was accentuated at the rehabilitation site where roots were confined closer to the surface. These results indicate that plants at the rehabilitation site are more dependent on small pulses of water and have less access to deep reserves than plants at the natural site. It is concluded that high runoff losses and insufficient soil depth are major factors contributing to plant water stress, and combined with the direct impacts of erosion, are largely responsible for plant death and ultimately poor plant cover. These issues can be alleviated if cover soil depth is increased to more than 0.5 m and slope angles are reduced to <12o. This study demonstrates the value of an ecophysiological approach for diagnosing problems affecting plant establishment at mine-rehabilitation sites. Furthermore, it has provided recommendations that will improve the rehabilitation strategy and lead to the development of a well vegetated, resilient ecosystem on a stable and non-polluting land form.

Doctor of Philosophy in Science to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, 1985This volume contains a record of research carried out over the past two decades into problems associated with civil engineering and mining construction materials. Although the various parts of the work were initiated as a result of problems that arose in the Witwatersrand region, the results of the research have in many cases evoked intense interest from other parts of the world. For example, the work on soluble salts in road bases has been taken up in Saudi Arabia and other desert regions, while that on the stability of waste rock dumps has been adopted as a basis for rock dump design in the United States of America. The research revolves entirely about materials, usually, waste, either produced by the mines and reused or disposed of by civil engineers; or reused to provide support by the mines · themselves. The main aim and end result of the research has been a more effective and efficient use of materials and better protection and control of the local environment.

The monograph examines the problems of sustainable development and energy efficiency using the scientific and methodological approach proposed by the authors for the development of regional fuel and energy programs based on the KhMAO, the Sverdlovsk region, and the oil and gas production enterprise JSC Yuganskneftegaz, and presents the results of the environmental and economic assessment. This approach allows us to evaluate and select the most effective investment project for the utilization of associated petroleum gas from the point of view of energy, environmental and climate security on comparable indicators (tons, rubles). The authors proposed to distinguish from more than 200 UN indicators four basic indicators: the change in the green area (country, region, city, household) for the year; the level of energy efficiency; the amount of pollutants released per year; the annual amount of greenhouse gas emissions. It is proposed to consider the possibility of using the" energy " ruble of S. A. Podolinsky (kW / h) as a possible world reserve currency. Taking into account the unique experience of the region's participation in various projects of sustainable development, energy-efficient and low-carbon economy, it is proposed to create a market for waste and greenhouse gas emissions on the basis of the trade exchange of the Sverdlovsk region as a pilot platform for the implementation of the green economy. The history of the term "green economy", the essence of this concept is considered; the results of the application of green economy in different countries are shown. The international experience of green solutions and technologies is analyzed, the psychological aspects of the transition to a green economy are studied. For all those interested in the environmental development of the economy.

Various chemicals and heavy metals are released into the environment through industrial and manufacturing processes, agricultural use, the use of industrial and consumer goods, and the mismanagement and dumping of wastes. Such releases can cause major environmental and human health problems, both at the local level and across national borders. International cooperation can be a way of addressing the risks posed by hazardous substances and wastes. States and intergovernmental organizations (IGOs) have engaged in technical collaboration and policy-making on these issues for more than a century. Today, a host of IGOs work on policy-making and management of hazardous substances and wastes, including the International Labor Organization, the Intergovernmental Forum on Chemical Safety, and the Global Environment Facility. Multilateral cooperation on hazardous substances and wastes takes place under three separate treaties: the 1989 Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal, the 1998 Rotterdam Convention on the Prior Informed Consent Procedure for Certain Hazardous Chemicals and Pesticides in International Trade, and the 2001 Stockholm Convention on Persistent Organic Pollutants. A substantial amount of scholarly literature covers numerous issues associated with hazardous substances and wastes, such as multilateral and national waste controls, persistent organic pollutants, and regional environmental policy developments. The case of hazardous substances and wastes can be used to further investigate the characteristics of vertical and horizontal institutional linkages and linkage politics, as well as the diffusion of principles, norms, ideas, and regulatory approaches across multilateral forums and national societies.

Mineral resources are important material resources for the development of national economy, but the long-term linear and extensive mining mode leads to low exploitation and utilization of resources and serious waste of resources on the one hand; on the other hand, the environment of mining areas is deteriorating, and safety problems are prominent. Correctly handling the relationship between mineral resources, environment, and economic development has become the main problem of sustainable development of mineral enterprises. There are still some problems in the mine. Therefore, it is particularly necessary to explore the construction path model of green mine under the background of the new era. Based on the coordinated development of resources, environment, and regional economy, this chapter studies the green mine construction mode by using the knowledge of resource economics, mining science, and sustainable development theory, combining theory with empirical analysis and qualitative and quantitative analysis.

Modern hospital practices with galloping growth in medical technology facilitate increase human life span, decrease mortality rate and increase natality rate. Life supporting health services generates potentially hazardous and infectious hospital wastes like pharmaceuticals, cottons, food, paper, plastics, radionuclide, sharps, and anatomical parts etc. These wastes are complex in nature with maximum part of municipal solid waste and small part of biomedical waste (anatomical parts, body parts etc.). Improper conduct and management of hospital waste create several problems and nosocomial diseases to human beings and harms environment. Traditional practices included for management are open burning, mixing waste, liquid discharge and waste disposal without treatment normally. Hence, this issue comes in lime light and several guidelines come to sort out this problem. Thus, challenges associated with traditional hospital waste management techniques and modern techniques for management are assessed in general and association with human society in particular in this chapter.

Thailand covers an area of 513,120 km2 and is located in the southern region of the continent of Asia. The total population was around 67.2 million in 2016. With increasing population growth, city expansion and rapid industrialization, generated 27.37 tonnes of waste in 2017. Thailand government has recognized problems associated with solid, hazardous, and electronic waste generation and issued policies/regulations to support the waste management system. Initiatives such as roadmap for municipal and hazardous waste, national master plan on cleaner production and cleaner technology, and national integrated e-waste management strategy have been introduced to improve the waste management system. However, there are many issues preventing the implementation of a successful waste management system in Thailand. Society has suffered from waste mismanagement because of lack of awareness and realistically applicable technology. There are also weaknesses in the processes of public participation, policy implementation, and institutional support.

This chapter describes how environmental pollution is the major problem associated with rapid industrialization, due to which the quantity of solid waste generated from the industries is increasing substantially. Solid wastes generated in leather industries are briefly classified into pre-tanned and post-tanned wastes. Although landfills, composting, anaerobic digestion and thermal incineration are available for disposal of these solid wastes, they do again pose severe environmental and financial burdens to the tanners. Microbe-mediated tannery solid waste management points to the recovery of value-added products from these wastes. Microbial valorization of tannery solid wastes for the production of saleable products would be a convincing, challenging and eco-friendly opening for its utilization when compared to that of chemical and thermal hydrolysis. Exploitation of traditional chemicals could be reduced and innovative products could be recovered, enabling sustainable solid waste management. This would ultimately alleviate the solid waste disposal problems and financial crisis faced by the tanners.

During 1990-2020, the global auditing/accounting and management consulting industry sectors experienced significant structural changes which have had un-even effects among large, medium and small auditing firms. The first section of this chapter summarizes the structural changes. The second section summarizes the antitrust problems. The third section discusses some of the climate-change and environmental pollution problems that are significantly affected by regulation of accounting firms and consulting firms; and introduces new solutions. In many countries, accounting firms have the primary responsibility for auditing firms' compliance with mechanisms such as emissions credits, environmental/sustainability accounting and compliance with environmental regulations; and consulting firms (by advising boards-of-directors and senior executives) informally and substantially influence firms' policies and procedures pertaining to waste/pollution and climate-change. The topics of the three sections (structural change, antitrust and the auditing/consulting firms' role in external audits and strategy pertaining to pollution, climate change and waste-management) are linked and or can have symbiotic effects on each other.

Biodiesel production or synthesis by non-edible oils has been introduced recently due to its potential to overcome the problems associated with first generation of feedstock, especially the competition between food and transport biofuel. The production of this non-edible resource could be done without major investment and benefit many parties involved: agricultural sector, job creator, biodiversity, and many other benefits. Microwave-assisted technique has been found as one of the methods that has the potential to be a highlight due to its ability to reduce the cost production and produce higher quality biodiesel as well. This method has been identified to enhanced and accelerate the transesterification process in order to obtain higher yields in the biodiesel synthesis. Continuous process in the other hand seems to be more significant when compared to batch solution. This review is an attempt to gather and summarize the existing literature and study the natural heterogeneous catalyst as one of the green and economic methods using microwave irradiation method.

Plastic, one of the most preferred materials in today's industrial world, is posing a serious threat to the environment and consumer health in many direct and indirect ways. The global plastic production increased over years due to the vast applications of plastics in many sectors. More than 50% of the plastic waste generated in the country is recycled and used in the manufacture of various plastic products. The remaining half is disposed of at landfill sites or simply burned in incinerators. The burning of plastics, especially PVC, releases this dioxin and also furan into the atmosphere. In this chapter, the authors examine the environmental and health effects and harm caused by the burning of plastics in detail. It focuses on the current status of plastic waste management in India and industries working under the extended producer responsibility. Therefore, an attempt has been made to review the current practices prevalent in India to deal with this plastic waste and problems associated with it.

Nutrients contribute to the wellbeing of water bodies. However, excessive enrichment of water bodies by nutrients could harm aquatic organisms. Some of the severe environmental problems caused by nutrients on water bodies include eutrophication and algal bloom. In children, consumption of nitrate-polluted water causes methaemoglobinemia. Consumption of food irrigated with nutrient-polluted wastewater has been associated with several health implications. These nutrients primarily originate from point and non-point sources. Several biological-suspended treatment systems have been developed to reduce nutrients to acceptable limits prior to discharge into water bodies. These treatment systems are associated with several merits and demerits. This chapter explores the implications of water body enrichment by nutrients and their impact on health, economy, and environment. Furthermore, some suspended growth treatment systems applied for the treatment of nutrient polluted wastewater were explored.

Recent population growth and economic development are extending the problems associated with land degradation, pollution, urbanization, and the effects of climate change over large areas of the earth’s surface, giving increasing cause for concern about the state of the environment. Many problems are most acute in tropical, equatorial, and desert regions where the surface environment is particularly fragile because of its long history of intense chemical weathering over geological timescales. The speed and scale of the impact of human activities are now so great that, according to some authors, for example, McMichael (1993), there is the threat of global ecological disruption. Concern that human activities are unsustainable has led to the report of the World Commission on Environment and Development Our Common Future (Barnaby 1987) and the establishment of a United Nations Commission on Sustainable Development responsible for carrying out Agenda 21, the action plan of the 1992 Earth Summit in Rio de Janeiro, Brazil. Considerable research into the global environment is now being undertaken, especially into issues such as climate change, biodiversity, and water quality. Relatively little work has been carried out on the sustainability of the Earth’s land surface and its life support systems, however, other than on an ad-hoc basis in response to problems such as mercury poisoning related to artisanal gold mining in Amazonia or arsenic poisoning as a result of water supply problems in Bangladesh (Smedley 1999). This chapter proposes a more strategic approach to understanding the distribution and behavior of chemicals in the environment based on the preparation of a global geochemical baseline to help to sustain the Earth’s land surface based on the systematic knowledge of its geochemistry. Geochemical data contain information directly relevant to economic and environmental decisions involving mineral exploration, extraction, and processing; manufacturing industries; agriculture and forestry; many aspects of human and animal health; waste disposal; and land-use planning. A database showing the spatial variations in the abundance of chemical elements over the Earth’s surface is, therefore, a key step in embracing all aspects of environmental geochemistry. Although environmental problems do not respect political boundaries, data from one part of the world may have important implications elsewhere.

The paper will start with an overview of the organisational and financing framework established in Spain for the safe and efficient management of radioactive waste and decommissioning of nuclear installations. Since its creation by Royal Decree in 1984, ENRESA, the Spanish Radioactive Waste Management Agency, is in charge of both activities. ENRESA is a state owned company whose shareholders are CIEMAT (Centro de Investigaciones Energe´ticas, Medioambientales y Tecnolo´gicas) and the State Industrial Holding (SEPI), both governmental institutions. In Spain the Directorate General for Energy Policy and Mines of the Ministry of Economy (MINECO) plays the leading role in controlling nuclear activities, since it is the body responsible for awarding licenses and permits for installations and activities within the framework of the existing nuclear legislation. The Nuclear Safety Council (CSN) was set up in 1980 as the only competent body in matters of nuclear safety and radiological protection, and is generally responsible for the regulation and supervision of nuclear installations. Any license granted by MINECO is subjected to the mandatory and binding report of the CSN. The paper will review the steps undertaken for solving the national problems associated with the management of radioactive waste and decommissioning of nuclear installations, including uranium mining and milling facilities, and will address the lessons learnt from the activities developed by ENRESA and the future goals to be met. Regarding the L/ILW (Low and Intermediate Level Radioactive Waste) programme, the main milestones of El Cabril L/ILW disposal facility will be described highlighting the most relevant events as well as the foreseen activities, most of them focus on optimizing the capacity of the already operating installation. The elaboration and signature of a Protocol, at the end of 1999, for collaboration on the radiological Surveillance of Metallic Materials in order to detect the possible presence of radioactive materials is worth to be mentioned because of the involvement and agreement of several public and private organisations as well as the administration. Concerning the SF and HLW (Spent Nuclear Fuel and High Level radioactive Waste) programme, the solutions adopted in order to solve the insufficient capacity of the storage pools at NPPs will be described as well as the evolution of the final disposal programme since its beginning and the foreseen goals to be achieved before the year 2010. The last activities will deal with the experience gained during the decommissioning of Vandello´s I NPP and the future decommissioning projects. The decision taken in 2002 by the Spanish authorities to close down Jose´ Cabrera NPP in April 2006, before its 40 years lifetime, has had an impact on ENRESA’s activities.

Abstract Uranium mineralization is associated with the gold deposits in South Africa that have been mined for more than a century. Investigations of the radiological impacts on the environment reveal that the various radioactive wastes — mostly of low activity — associated with gold and by-product uranium production do not warrant the application of anything more than basic control measures. Non-radiological pollution of the water environment is a growing problem, however, aggravated by the closure and flooding of mines. Control measures to address this problem should, as a spin-off, limit the release of radionuclides, thus helping to control future radiological pollution.

The Gunnar Mine and mill site was the largest of some 38 now-abandoned uranium mines that were developed and operated in Northern Saskatchewan, Canada, during the Cold War years. During their operating lifetimes these mines produced large quantities of ore and tailings. The Gunnar mine (open pit and underground) produced over 5 million tonnes of uranium ore and nearly 4.4 million tonnes of mine tailings during its operations from 1955 through 1963. An estimated 2.2 to 2.7 million m3 of waste rock that was generated during the processing of the ore abuts the shores of Lake Athabasca, the 22nd largest lake in the world. After closure in the 1960s, the Gunnar site was abandoned with little to no decommissioning being done. The Saskatchewan Research Council has been contracted to manage the clean-up of these abandoned northern uranium mine and mill sites. The Gunnar Mine, because of the magnitude of tailings and waste rock, is subject to an environmental site assessment process regulated by both provincial and federal governments. This process requires a detailed study of the environmental impacts that have resulted from the mining activities and an analysis of projected impacts from remediation efforts. The environmental assessment process, specific site studies, and public involvement initiatives are all now well underway. Due to the many uncertainties associated with an abandoned site, an adaptive remediation approach, utilizing a decision tree, presented within the environmental assessment documents will be used as part of the site regulatory licensing. A critical early task was dealing with major public safety hazards on the site. The site originally included many buildings that were remnants of a community of approximately 800 people who once occupied the site. These buildings, many of which contained high levels of asbestos, had to be appropriately abated and demolished. Similarly, the original mine head frame and mill site buildings, many of which still contained the original machinery and equipment, also had to be dismantled. Remediation options for the accumulated demolition debris have been assessed, as have remediation options for the waste rock and tailings, all of which form part of the environmental assessment. The regulatory requirements include the environmental assessment processes, a complex public involvement strategy, and licensing from the Canadian Nuclear Safety Commission (CNSC) with the long-term goal of releasing the property in a remediated and stable state to the Province of Saskatchewan. Prescribed environmental and land-use endpoints will be determined based on the environmental assessment studies and remediation options analyzed and implemented. Ultimately, the site will be released into an institutional controls program that will allow long-term government management and monitoring.
