Abstract:

Mining activity is suspected of contributing sulfate and total dissolved solids (TDS) to ground water downgradient of the Pima mining district. High ionic concentrations in tailing impoundments suggest that tailings-pond recharge may be a source of the contamination. Experiments indicated that sulfate is not significantly produced by inorganic sulfide oxidation in the tailings ponds. Tailings pond water chemistries were compared with historical water quality analyses in the Pima district. The U.S.G.S. computer program PHREEQE modeled saturation indices for anhydrite, calcite, fluorite, and gypsum in water chemistries throughout the study area. Well water downgradient of the mines had lower saturation indices than tailings pond water which discredits the claim that tailings-pond recharge is acquiring salts as it percolates to the aquifer. Evidence supports the opinion that tailings pond seepage is contributing to the sulfate and TDS content in ground water downgradient of the ponds.

Abstract:

The objective of this thesis has been to analyze whether booms in the iron ore market has any significant effects on local labor markets in certain municipalities in Norrbotten County during the time period 2000-2016. Previous research has established that certain types of booms and busts influenced local labor markets. The analysis was done by using panel data and regression models where the results where compared over non-mining and mining municipalities. The results gave a vague response with both conclusive and inconclusive results over the variables investigated. The main conclusion is that although the mining industry is a big part of local labor markets in Norrbotten County, it is important for firms and policymakers to understand that the mining industry is not the only important factor and that decisions should not be entirely based on the mining industry and its markets.
Målet med denna uppsats var att analysera ifall booms i järnmalmsmarknaden har någon signifikant påverkan på lokala arbetsmarknader i utvalda kommuner i Norrbotten under tidsperioden 2000–2016. Tidigare forskning har fastställt att vissa booms och busts kan influera lokala arbetsmarknader. Analysen har genomförts med paneldata och regressionsmodeller där resultat jämförts mellan gruvkommuner och ickegruvkommuner. Resultaten gav otydliga resultat då vissa var konklusiva medan andra inte var konklusiva. Den huvudsakliga slutsatsen som nåtts är att även om gruvindustrin är en viktig del av de lokala arbetsmarknaderna, är det viktigt för företag och beslutsfattare att förstå att gruvindustrin inte är den enda påverkande faktorn och att framtida beslut och satsningar inte enbart ska baseras kring gruvindustrin och dess marknad.

Abstract:

South Africa is one of the most biologically diverse countries in the world. However, biodiversity is suffering under the huge demand for natural resources and the increasing dependence of rural communities on these same resources. It has also become apparent that an alarming number of species are threatened, endangered or even destroyed. Surveys have revealed that 34% of the country’s 440 terrestrial ecosystems are threatened. The three severest threats to biodiversity are overexploitation, overgrazing and mining. There is however a range of international, regional, national and local laws and best practice guidelines that aim to protect and preserve the natural faunal and floral diversity of the various rural areas and regions. The prescription of sustainable practices enables communities that depend on the services of ecosystem in their area, to utilise without depleting the resources provided by nature. South Africa is a signing party to more than seven conventions and treaties that either protect or govern biodiversity. In addition to this, the South African government has promulgated eighteen pieces of legislation and guidelines to protect and govern the use of biodiversity. The focus of this study was on the impacts platinum mining have on biodiversity and how effectively these impacts are managed. Data for the case study was obtained from Impala Platinum. Impala leases its land from the Royal Bafokeng Nation and inter alia shares it with the people who use the areas in between for grazing and other subsistence activities. The aim of the study was, in the first place to identify how Impala Platinum’s Environmental Management Plans (EMP’s) and Closure Plan (which manages current and post mining activities and their impacts) are aligned with the various international, national and local requirements for biodiversity management, and secondly to evaluate the effectiveness of the current management measures put in place, which regulates activities impacting on biodiversity. To give effect to the above outcome it was necessary to first identify the various international, national and local treaties, legislature and guidelines. Secondly, an environmental risk assessment was conducted where the current management measure were weighed against the various international, national and local requirements in order to deduce the level of effectiveness of the current EMP’s and Closure plan. It was found that the majority of the EMP’s compiled under the Environmental Conservation Act No. 73 of 1989 (ECA) lack substantive management and preventative measures. It was only in the later EMP’s (between the years 2000 - 2004) that the prescribed management measures improved and became more effective. This was because the Environmental Impact Assessment (EIA) process had matured in South Africa and an entire new regime of more descriptive EIA regulations had been promulgated under the National Environmental Act No. 107 of 1998, which repealed the majority of the outdated ECA regulations. It was also found that the environmental standards, management objectives and priorities that were developed in the EMP’s did not contingently and specifically reflect the conditions in relation to the environmental, developmental and biodiversity contexts to which they apply. The Closure plan on the other hand, was a regurgitation of the same unimaginative objectives focusing on remedying past legacies instead of providing a lasting solution to sustain and improve the environmental conditions left by the mine, and most importantly it does not address the social issues that result from mine closure. For example, the overexploitation and overgrazing of the areas in between the various mining operations by the Royal Bafokeng Nation’s people is a crucial aspect that has not been thoroughly addressed in the respective documents. Habitat disturbance, which was not addressed for instance, requires a wide range of actions e.g. educating local communities on pasture management, post–rehabilitation monitoring, amelioration etc. To improve compliance with current legislation and adherence to the guidelines proposed by best practice initiatives, various recommendations are put forward to control both the negative activities brought on by the Royal Bafokeng and Impala Platinum. These include the implementation of: Biodiversity (inclusive) impact assessment, good environmental governance, the precautionary approach, the ecosystems approach, sustainable biodiversity management practices through conservation planning, biodiversity action plans, stewardship and land care tools, conservation plans, biodiversity offsets, effective mine closure planning and the forming of a Biodiversity Action Steering Committee (BASC). Finally, an eight step model is proposed as a tool to evaluate the effectiveness of specifically the platinum mine’s EMP’s and Closure plans to manage activities affecting biodiversity. The model is based on the concepts of direct and indirect drivers of change and the Deming cycle and is an elaboration of the model proposed by UNEP and the International Association of Impact Assessment. The model focuses on both the natural and anthropogenic drivers that may affect biodiversity and will aid the management of a mine to supplement the shortcomings of these documents. As an indirect outcome the model may possibly even improve, the relationship between the specific company and the communities with which it shares its land.

Abstract:

The purpose of this dissertation is to evaluate the feasiblity of alumina production in Ghana to replace imported alumina for the production of aluminum. It spells out the conditions which led to the existing bauxite-alumina-aluminum trade in the country. The structure of the economy of Ghana is examined to show the contributions of the important sectors to the total income of the country, and its dependence on a few export commodities for revenue. The plan to build a dam for the generation of hydroelectric power was linked to the establishment of an integrated aluminum industry based on the exploitation of domestic bauxite reserves. As the country could not finance the project alone, foreign assistance was sought. VALCO, a subsidiary of Kaiser and Reynolds, was formed to undertake the project. The agreement reached with VALCO was that a smelter would be built to use imported alumina for ten years, during which time a refinery would be built to feed the smelter from domestic sources. However, after ten years this could not be achieved, and the smelter continues to use imported alumina. A model of the world aluminum economy is used for analyzing the sensitivity of price to production and consumption expansion. The results show that industry demand is sensitive to the level of industrial activities in the developed countries, and less sensitive to the own price and cross price variables of aluminum in both the short and long run. On the other hand, supply is inelastic to the own price and the rate of capacity utilization in the short run, but elastic to both variables in the long run. An appraisal of opening a bauxite mine and an alumina refinery at Kibi is undertaken. The results show the levels of bauxite and alumina prices and the costs of construction at which the project is feasible. The shadow values and weights used are permittd to vary with changes in the economy's foreign trade and the balance of payments.

Abstract:

Various filtering and integration techniques were used to analyze geologic, geophysical and geochemical data from the Twin Peaks area located in the DeLamar mining district in Southwestern Idaho. In particular rank correlation and favorability analysis were employed in this study. The data analysis was used to delineate target areas considered favorable for epithermal gold-silver mineralization. The interpretation of geophysical data was emphasized because of the importance of subsurface geologic features and complications caused by post mineral cover. Field investigation of the target areas provides strong evidence supporting the potential for significant mineralization in four of the twelve target areas selected.

Abstract:

The aim of the thesis "Peru: developing country with mineral wealth" is to analyze the most prosperous economic sector in Peru, which is the mining industry. Although Peru is a developing country in the world known for its rich history, also has big economic potential, which still faces many challenges. Peru belongs to the world's ten largest producers and holders of the world's reserves of silver, copper, zinc, lead, tin, and gold. In addition, this sector is important to the global level, it has a big impact on the Peruvian economy After obtaining independence in 1821, Peru has undergone periods of political unrest, financial crises and phases of stability and economic growth. During the colonial period was indigenous people often exploited and their culture suppressed. Today the indigenous population of about half the population live mostly in the traditional way of life in mountain areas and Amazon jungle. Liberalization reforms in the 90s opened Peru doors to economic prosperity, but also a deepening social differences. The work uses the methods of analysis, synthesis and comparison and is divided into four chapters. The first chapter of the thesis deals with the general definition of the developing world, with an emphasis on developing region of Latin America. Second chapter is focused on Peru's political, economic and social development. Third chapter belongs to the most significant sector of the Peruvian economy, mining industry and its impact in the world and domestic economy. This sector faces big problems as informal mining and social conflicts because of the pollution. Last chapter aims to assess the future development of the mining industry in Peru, which affect the internal and external influences of the global and national economic situation.

Abstract:

Within the last decade text mining, i.e., extracting sensitive information from text corpora, has become a major factor in business intelligence. The automated textual analysis of law corpora is highly valuable because of its impact on a company's legal options and the raw amount of available jurisdiction. The study of supreme court jurisdiction and international law corpora is equally important due to its effects on business sectors. In this paper we use text mining methods to investigate Austrian supreme administrative court jurisdictions concerning dues and taxes. We analyze the law corpora using R with the new text mining package tm. Applications include clustering the jurisdiction documents into groups modeling tax classes (like income or value-added tax) and identifying jurisdiction properties. The findings are compared to results obtained by law experts.

Full text

Abstract:

In 1996, an estimated 400,000 people in a gold mining community in rural Tanzania were forcibly evicted from the area to allow for the development of a large-scale gold mine project to take place. The good-intentioned project was based on the idea of putting national development and public interest before the individual or community development and private interest. This thesis set out in 2006 to investigate how the livelihoods of the displaced community were affected by this development project. The main conclusion is that the displaced individuals had become poorer in 2006 than they were before the eviction. National development has impoverished and underdeveloped them.

The study was guided by the theory of political ecology, which I used in combination with the impoverishment risk model, focusing in particular on livelihoods. Data for this study was collected through qualitative methods as well as from secondary sources.

Using political ecology, I have been able to argue that the case study reflects a conflict over land resources, and struggles and contestations over power and meanings in society. The apparent local conflict should also be understood from the global political economy perspective.

The findings confirm the impoverishment risk model which argues that during displacement or resettlement, unless mitigative measures are taken, it is likely that the displaced people would become landless, homeless, jobless and food insecure among other negative elements. These risk elements have been found in the study area, and according to the respondents, they were a result of the displacement. On the other hand, the livelihood analysis shows how individuals and communities have been able to cope in the face of change. One of the main lessons from the study is that the project-affected people have some agency and are eager to develop themselves rather than wait for development to be brought to them by government or foreign investors. Their key concern at the moment, however, is lack of a fair compensation.

Full text

Abstract:

The majority of research studying the ecological impacts of the coal mining industry on freshwater systems has focused on abandoned-mined land, and the associated acid drainage and metals toxicity. Treated discharges from active mining and preparation facilities, however, can also impair lotic ecosystems through total dissolved solids (TDS) toxicity, caused primarily by the reagents used for pH modifications and the oxidation of reduced sulfur. Such impairment was best detected through application of (1) benthic macroinvertebrate surveys using metrics of biotic impairment such as relative Ephemeroptera abundance and Ephemeroptera-Plecoptera-Trichoptera (EPT) minus the tolerant caddisfly family Hydropsychidae (2) in situ growth of Corbicula fluminea during 96-d exposure and (3) laboratory testing using Ceriodaphnia dubia. Traditional metrics such as total taxa richness, EPT, diversity and biotic indices were not sensitive to elevated TDS levels.

Further study using strength of evidence, regression analysis and manipulation of laboratory formulated media, indicated that the mine effluent was the primary causal agent of the observed biotic impairment, and its toxicity could be attributed to sodium/sulfate-dominated TDS, which is significantly ameliorated by water hardness. Finally, although testing with lentic cladocerans, such as Ceriodaphnia, is consistent, cost-effective and sensitive to TDS related toxicity, the ecological relevance and protective capability of such testing is questionable when assessing contaminant effects on sensitive macroinvertebrates indigenous to lotic systems. A more ecologically relevant laboratory bioassay using the mayfly, Isonychia bicolor, in simulated lotic microcosms provided more sensitive endpoints than Ceriodaphnia and Pimephales promelas. Although the heartiness of Isonychia in laboratory conditions is poorly understood relative to standardized test organisms, these results, along with potential toxic impacts from numerous sodium/sulfate-dominated wastewaters discharging into freshwater systems, may have important implications to future national pollution discharge and elimination system (NPDES) permit testing. Currently, however, strong recommendations can only be made using Ceriodaphnia endpoints. Potential acute toxicity to aquatic organisms in high hardness solution (~790 mg/L as CaCO3) is possible where sodium/sulfate-dominated TDS levels exceed ~7000 uS/cm (5167 mg/L), with potential chronic toxicity occurring at ~3200 uS/cm (2342 mg/L). These endpoints were significantly reduced in solutions of lower hardness (88 mg/L as CaCO3), with acute and chronic toxicity occurring at 5100 uS/cm (3754 mg/L) and ~2100 uS/cm (1523 mg/L), respectively. Point source discharges causing instream TDS concentrations to exceed these levels risk impairment to aquatic life.

Abstract:

This embedded mixed method research was aimed to investigate the artisanal and small-scale mining related recordable injuries, associated risk factors and socio-economic consequences. 236 participants were surveyed, followed by interviewing of 33 severely injured miners. The results demonstrated that certain personal and operational risk factors influenced the likelihood of injuries, severity and frequency of injuries. Also, severely injured miners experienced negative socio-economic impacts. Improved strategies for injury prevention and post-injury consequences management are advised.

Abstract:

How do we account for foreign firms that are successful in politically “risky” countries? While traditional political risk indices may tell us why a country is considered a difficult operating environment, they tell us very little about why some foreign firms are nevertheless able to operate successfully in such countries over long periods of time. In fact, risk indices by their very nature make “success” almost impossible to capture due to their sole focus on “host country” behavior. Rather, as this thesis argues, the political risk is in the relationship between the firm and a series of stakeholders within a given country, not the country itself. This is a thesis of deviant cases: it holds the “successful relationship” between a foreign firm and its stakeholders as the constant dependent variable in the “significantly risky” country of Kazakhstan. Success is defined as the ability of each actor to pursue its own goals to a self-satisfactory degree, with the resources an actor mobilizes to achieve those goals and the constraints that restrict those resources as the independent variables. Three self-contained cases of “successful” foreign mining firms operating in Kazakhstan are analyzed here to determine the distinct causal pathways that led each firm to seeming “success”; the thesis then pivots to a between-subjects examination aimed at drawing out the common themes among the three different foreign firms. Within international relations theory, the relationship between the foreign firm and its stakeholders is considered here as a window into the intersection of the international political economy and the domestic political economy of a country in transition, but critically, allotting agents and structures equal ontological status. Thus the ultimate aim of this investigation is to enrich our understanding of social behavior – here, co-existence – within the context of the agent- structure debate in larger social scientific inquiry.

Abstract:

Most people are at least aware that, in the past, companies that owned mines, lumber mills, and other large-scale industrial projects in isolated areas also ran company towns. For many people, such towns conjure up images miserable working conditions, exploitative company stores, and inadequate shacks for most workers, while managers live in relative luxury up on “snob knob.” Most people are also fairly certain that such towns, at least in the United States, died out about the same time as the horse and buggy. Several industries in Wyoming, however, continued to support company towns through the end of the 20th century, with one such town surviving into the early 2000s. This project looks at two of these towns supported by the uranium mining and milling industry that dominated central Wyoming’s economy for about 30 years starting in the mid-1950s. These towns, Gas Hills and Jeffrey City, along with Wyoming’s other modern company towns represent a new era in the history of these communities. Furthermore, they actually had many advantages for inhabitants, companies, and the local economy, especially compared to a small conventional community located near a resource boom. Often, and in contrast to the towns in this thesis, conventional towns must scramble to meet the demands of a massive migration, only to be left with unpaid bonds when the resource dries up or becomes no longer profitable.

Abstract:

During the historic mining episodes at Cagle Saltpetre Cave, wooden leaching vats needed for the lixiviation of calcium nitrate from mined sediments (from which saltpeter was then produced) were constructed and used in the cave. When mining operations ceased, these features were abandoned and preserved in situ, some remaining virtually intact. Their remarkable preservation enabled tree-ring dating of timbers associated with these vats to be accomplished. Tree rings from oak planks used in the construction of the leaching vats were measured to 0.001 mm precision on a Velmex measuring system. Using COFECHA software, we crossdated the measurement series to both the Norris Dam State Park and Piney Creek Pocket Wilderness white oak reference chronologies, spanning the years from 1633 to 1982, obtained from the International Tree-Ring Data Bank. Graphical comparisons via scatter plots were inspected to ensure correct temporal placements. The final chronology developed from 39 dated series correlated very highly with the Norris Dam State Park reference chronology (r = 0.49, n = 170 yrs, t = 7.29, p < 0.0001) and verified that our site chronology extends from 1692 to 1861. The results of our analyses indicate that saltpeter was mined and processed at the site during separate episodes throughout the 19th Century. Additionally, saltpeter-processing technology changed throughout the course of the mining operations.

Abstract:

Reduced intrusion-related gold (RIRG) deposits have been documented around the globe, and have been best studied in Alaska and Yukon, but few examples have been documented in Nevada. One occurrence in Nevada is the Jurassic Bald Mountain deposit in eastern Nevada; however, for most Nevada occurrences there has been insufficient work that establishes a genetic connection to intrusions or determines their age.

Buffalo Canyon is a gold prospect located near the historic Berlin mining area in northern Nye County, Nevada, where gold, silver, copper, lead and zinc were mined in the past from mesothermal quartz veins. Buffalo Canyon contains the more recently discovered Everson prospect, a poorly defined gold deposit, which has characteristics of RIRG deposits. The district includes a series of intrusions emplaced into Triassic metasedimentary and metavolcanic rocks. These previously undated intrusions vary in composition from diorite to granodiorite and granite. U-Pb dating of zircons by LA-ICPMS has revealed distinct intrusive events in the Jurassic, Cretaceous, and Oligocene. Metaluminous, biotite-pyroxene diorite stocks to porphyritic granodiorite dikes have been dated at 162.03 + 0.91 Ma and 158.72 + 0.94 Ma, respectively. Peraluminous, ilmenite-bearing leucogranite plugs and dikes have been dated at 81.96 + 0.43 Ma and 82.9 + 0.30 Ma, respectively. A variety of Oligocene dikes and small plugs that include quartz-monzodiorite, quartz monzonite, dacite and granite are metaluminous to peraluminous and locally ilmenite-bearing. Four dates of Oligocene intrusions fall within error of each other. They yielded dates of 25.13 + 0.29, 24.9 + 0.30, 24.8 + 0.40 Ma and 24.6 + 0.30 Ma.

Country rocks at Buffalo Canyon, particularly those near Jurassic intrusions, are metamorphosed to biotite hornfels. Biotite hornfels is overprinted by sodic-calcic alteration that is likely related to Jurassic intrusive activity, and consists primarily of actinolite + albite in veins and disseminated patchworks. Mesothermal quartz veins have a Au-Ag-(Sb-Pb-As-Cu) geochemical signature, are composed predominantly of moderately deformed, recrystallized quartz and contain liquid CO₂-bearing fluid inclusions. Mesothermal quartz veins are hosted within Jurassic intrusions and are post-Luning-Fencemaker thrust (mid-Jurassic) deformation. Small volumes of Oligocene intrusive rocks are variably altered to muscovite-tourmaline or propylitic assemblages. Base-metal sulfide mineralization occurs as veins and replacements, both of which are associated with tourmaline as a dominant gangue mineral. Base-metal sulfide mineralization has a Ag-Pb-Zn-Sb-As-(Au-Bi-Cu-Mo) signature.

Free gold within low sulfide, 1-10cm thick, sheeted, crack-seal quartz veins with locally developed sericite-tourmaline envelopes define the bulk of the Everson gold mineralization. Other gangue minerals in these veins include muscovite, tourmaline and fluorite. The veins have a Au-Te-(Mo-Bi-Sn) signature and high Au:Ag ratios (>1:1). The quartz in these gold-bearing veins contain common hypersaline brine and coexisting vapor-rich fluid inclusions, indicative of trapping within the two-phase brine + vapor field. Combined with estimated thicknesses of older and coeval Oligocene volcanic rocks, the fluid inclusions suggest the deposit formed at <~3 km paleodepth. The Everson-related quartz veins also cross-cut mapped Jurassic intrusive rocks, sodic-calcic veins, base-metal sulfide mineralization, and Oligocene granitic intrusions. Muscovite and tourmaline + fluorite associated with alteration and mineralization suggest a greisen-like style of alteration and mineralization. The preponderance of evidence suggests that most gold mineralization at Buffalo Canyon is Oligocene in age, related to a felsic intrusion that only crops outs locally, but is likely extensive in the subsurface. Buffalo Canyon bears strong similarities to typical RIRG systems, and there are likely additional unknown examples within Nevada. A significant outcome of this study is that Buffalo Canyon formed in the Oligocene, related to volcanism during slab rollback that led to the ignimbrite flare-up in the central Nevada. Though most RIRG systems in Nevada could indeed be Mesozoic, the research on Buffalo Canyon opens the possibility that similar deposits may also be related to much younger intrusions that may be largely covered by coeval Tertiary volcanic rocks.

Abstract:

This thesis examines processes of political change in the Murton miners' and mechanics' branches of the National Union of Mineworkers (NUM) between 1978 and 1988. During this period both branches swung from the right of the NUM's political spectrum to the left. Recent debates in human geography - and the social sciences more generally - have drawn attention to the importance of place in analysing social developments. However, a review of the literature reveals a surprising lack of detailed studies undertaken at the local level. In order to understand the constraints under which events at a local level take place, it is necessary to place them in context. The coal industry is therefore located at the centre of a complex set of institutionalised relationships between capital, labour and the state known as the "post war settlement" (PWS). As economic crisis deepened in the 1970's, the PWS came under attack. In the coal industry this led to the progressive destabilisation of a characteristic "indulgency pattern" which had built up in the post war years. At Murton, this destabilisation created the room for left wing activists to build support in miners' and mechanics' branches. However, their impact was unevenly distributed among the workforce because miners from different backgrounds were affected in different ways by the crisis in the industry. Cleavages of age and residence led to significant differences in miners' and mechanics' understanding of the crisis facing the industry. This thesis examines the interaction between local union branch leadership, the changing situation in the coal industry, and divisions within the workforce during three distinct periods: from 1978 until the eve of the 1984/5 strike; the strike itself; and the period since the strike until the end of 1988.

Abstract:

The first diamond mine in North America was discovered in 1906 when John W. Huddleston found two diamonds on his farm just south of Murfreesboro in Pike County, Arkansas. Experts soon confirmed that the diamond-bearing formation on which Huddleston made his discovery was the second largest of its kind and represented 25 percent of all known diamond-bearing areas in the world. Discovery of the field generated nearly a half century of speculative activity by men trying to demonstrate and exploit its commercial viability. The field, however, lacked the necessary richness for successful commercial ventures, and mining was eventually replaced in the early 1950s by tourist attractions that operated successfully until 1972. At that time the State of Arkansas purchased the field and converted it to a state park. Thus this work tell the rich and complicated story of America'a once and only diamond field, analyzes the reasons for the repeated failures of efforts to make it commercially viable, and explains how it eventually succeeded as a tourist venture.

Full text

Abstract:

The coal industry exercises a pervasive influence on mining communities in Appalachia, even though it exerts enormous damages on the environment and makes limited contributions to employment and the advancement of the communities. One explanation for this paradox offered by Bell is a depletion of social capital among coalfield residents in Central Appalachia (2009). Her data suggests that the “ripping away” of the region’s strong union identity lead to a resocialization, “from a ‘we’ mentality to an ‘I’ mentality, thus demising the store of social capital” (2009:655). My research aims to interpret how social capital resources among union miners was translated to solidarity in the mining community, and how the union generated social capital and fostered solidarity among miners and their families. This research finds that the union was both a creator and a preserver of social capital. The coalfield residents demonstrated a high degree of social capital and solidarity in terms of a sense of reliability, dedication to collective activities, and intimate extended networks. Furthermore, the union’s strategies of holding regular meetings, organizing large-scale strikes, promoting collective identity, securing public benefits, and electing charismatic leaders were of great significance for the production of both social capital and solidarity.

Abstract:

Deep row incorporation of biosolids is an alternative land application method that may allow higher than currently permitted mine land reclamation application rates. Biosolids treated by various processes possess characteristics that uniquely affect metal solubility and mobility due to their influence on metal speciation. The objectives of this research were to compare the effects of biosolids stabilization type and rate on heavy metal solubility, mobility, and speciation. Two rates each of Alexandria, (Virginia) anaerobically digested (213 and 426 dry Mg ha-1) and Blue Plains (Washington, DC) lime-stabilized (329 and 657 dry Mg ha-1) biosolids were placed in trenches at a mineral sands mine reclamation site in Dinwiddie County, Virginia in June and July 2006. Vertical and lateral transport of heavy metals from the biosolids seams were determined by analyzing leachate collected in zero tension lysimeters below the trenches and suction lysimeters adjacent to the trenches. Chloride (Cl-), sulfate (SO42-), nitrate (NO3-), phosphate (PO43-), dissolved organic carbon (DOC), and pH were also determined within the dissolved fractions (< 0.45 Âµm) collected on September 8, 2006, November 3, 2006, January 5, 2007, June 8, 2007, and September 7, 2007 as input for the speciation program MINTEQA2. Silver, Cd, Pb, and Sn did not move vertically or laterally to any significant extent. Lime-stabilized biosolids produced higher cumulative metal mass transport per sampling period for Cu (967 g ha-1), Ni (171 g ha-1), and Zn (1027 g ha-1) than the anaerobically digested biosolids and control during the 15-month period following entrenching. Barium mass loss was similar for both biosolids. All metals moved primarily with particulates. MINTEQA2 predicted the majority of the metals within the dissolved fraction were present as free ions. As pH decreased and time increased, the amount of association with fulvic acids decreased allowing more free ions and binding with inorganic ligands. Little movement into groundwater demonstrates that anaerobically digested and lime-stabilized biosolids can be land-applied at high rates with little concern of heavy metal contamination of groundwater under these conditions.
