Abstract:

Monitored natural attenuation is a cost-effective remediation strategy for the risk reduction of chemicals of concern (CoCs) in contaminated land and waters. This study considers three genuine sites in Germany, undergoing remediation. The objective was to measure a suite of physicochemical and biological parameters, and characterise the sites based on these data. The sites differed by their prevalent type of CoC, with one site impacted by polycyclic aromatic hydrocarbons (PAH), and two sites, situated in Hilden, impacted by BTEX. Sampling of microorganisms was performed using the industrial partner's newly developed matrix. This matrix was used for measurements of microbial respiration rate, ATP content, and 14C mineralisation rate, while groundwater samples were used for microbial luminescent biosensor assays (applying Escherichia coli HB101 pUCD607, Pseudomonas putida F1 Tn5, and Pseudomonas putida F1 TVA8), and for the chemical analysis of CoC, nitrate, iron, manganese, sulphate, and phosphate concentration. Microbial biosensors and respiration tests performed well in the identification of BTEX impacted wells at the Hilden sites, while the results for ATP content and 14C mineralisation were more ambiguous. Factor analysis showed a high impact of sulphate concentration. However, several strong correlations existed between measured parameters, so no single driving force, but a set of environmental influencing factors could be identified at the sites. The remediation progress could be demonstrated by the changes in cluster analyses between two time points. Sulphate and redox potential, the most influential parameters of the Hilden physico-chemical data set, were highlighted and confirmed by multiple linear regression, using a calculated attenuation rate as the dependent variable. Based on this outcome, a reduced sampling regime was proposed. This approach has the potential to reduce sampling costs and time at hydrocarbon contaminated sites, and has adequately demonstrated the use of statistical methods in assessing the remediation progress at a site.

Abstract:

Aromatic hydrocarbons are a prevalent constituent of crude oil. The refined products of crude oil such as petroleum and diesel can find their way into groundwater though oil-spillages and are also present in the oil and gas industry’s produced water. These aromatics are biorecalcitrant, however upon ingestion with water, may be metabolised to toxic intermediates that are carcinogenic or mutagenic in nature. Although some treatment technologies are available most of these are under development and are yet to be proven in the field. This illustrates the need for novel, economical and environmentally friendly technologies to be developed with a view to remediating aqueous systems that have been polluted with aromatics hydrocarbons. The supramolecular cyclodextrin molecule, with its hydrophobic interior and hydrophobic exterior seems to be an excellent molecule for the trapping of the pollutant molecules, however the inclusion complexes with this cyclic sugar are water-soluble therefore there is a need for the cyclodextrin to be rendered waterinsoluble. A study of the aqueous solubilities of some aromatic hydrocarbons that may be present in crude oil has been carried out and shows that the majority of these molecules have a degree of water solubility that may increase upon environmental weathering. The successful reaction between a solid-phase resin and the β-cyclodextrin molecule has been achieved, with the total dryness of the system being required including Soxhlet extraction of the resin with anhydrous acetone before the reaction. The reaction between β-cyclodextrin and a range of isocyanates proved unsuccessful, but a range of symmetrical aryl ureas were synthesised from their isocyanates with the influence that different activating or deactivating groups on the ring have on the propensity to form the ureas being shown. The successful alkylation between β-cyclodextrin and a series of haloalkanes has shown the effect of increasing chain length on the degree of alkylation. This reaction involved the deprotonation of the cyclodextrin by sodium hydride in anhydrous dimethyl sulphoxide followed by reaction with the alkyl iodide. Increasing the equivalents of hydride or iodide, or the reaction time did not have a noticeable effect on the degree of reaction indicating that steric constraints were limiting the degree of reaction. Testing several of these alkyl iodides gave an indication as to their tendency to uptake and remove several model pollutants that had been dissolved in water with the propylated β-cyclodextrin displaying potential for the remediation of aqueous systems that had been polluted. Several of these results were very promising leading to the conclusion that further derivatives of these alkylated sugars may be even more suitable for future research into the remediation of organically polluted aqueous systems.

Full text

Abstract:

Providing access to clean drinking water will continue to be a challenge for civil engineers for generations to come. Since many communities around the world rely on groundwater as a source of drinking water, remediation technologies must be implemented at sites where groundwater contamination exists due to years of mismanagement of hazardous waste. Using nanosized zero-valent metals such as iron and zinc embedded within and on the surface of functionalized (PAA) membrane filters has shown to be an effective dechlorination technique for contaminated groundwater. Introducing a noble metal such as Pd or Ni increases reaction rates by acting a catalyst for the dechlorination reaction. This study focuses on the treatment of contaminated groundwater at a hazardous waste site in Louisville, Kentucky. Once a chlorinated organic chemical manufacturing plant, the site now operates a treatment system for the contaminated groundwater to prevent migration into the nearby Ohio River. A portable membrane treatment system, built at the University of Kentucky, incorporates this functionalized bimetallic membrane technology for treatment of the groundwater found at the former manufacturing plant. Three bench scale tests were performed with membrane treatment system using DI water spiked with the chemical trichloroethylene (TCE). Results showed that using the functionalized Fe/Pd membranes significant decreased TCE concentrations over time. While further tests should be conducted to verify the results of the preliminary bench-scale tests, the membrane treatment system shows potential for use at the hazardous waste site in Kentucky.

Abstract:

Extractive processes can permanently and significantly reduce the volume, toxicity and mobility of contaminated materials at affected sites. Ethylenediaminetetraacetic acid (EDTA), N-2 (acetamido)iminodiacetic acid (ADA), pyridine2,6-dicarboxylic acid (PDA), and hydrochloric acid (HC1) were evaluated in batch studies for their ability to remove lead (Pb) and cadmium (Cd) from a Superfund soil. The extraction of Pb as a function of time was limited and the order of Pb removal was EDTA > ADA > PDA > HC1. Repeated extractions did not treat the soil below the Pb regulatory limit (1,000 mg/kg); however, the Pb remaining occurs in an immobile form. All extractants treated the soil below the proposed Cd regulatory limit (40 mg/kg) within 1 h. Lead recovery from solution was accomplished by hydroxide precipitation in the presence of excess calcium, and recovery at pH 11 was 70%, 98%, and 97% from the EDTA, ADA, and PDA complexes, respectively.

Full text

Abstract:

Hydrazine (HZ) and monomethylhydrazine (MMH) are used extensively as hypergolic propellants at Kennedy Space Center. These highly reactive fuels are considered highly toxic, and potentially carcinogenic. Consequently, the transport, handling, and disposal of hydrazines is strictly regulated to protect personnel and the environment. Currently, KSC generates large volumes of hydrazine-laden wastewater for disposal. This waste is contained and shipped on public highways for subsequent disposal by incineration presenting a potentially catastrophic threat to the environment and the general public in the event of an accidental release. Other existing remediation methods include oxidative and reductive pathways as well as biodegradation in fixed film reactors. Each of these methods has associated drawbacks and limitations that make them unsuitable for industrial use. Recently, hydrazine neutralization by reaction with alpha-ketoglutaric acid (AKGA) to form the stabilized pyridazine derivatives PCA and mPCA has been explored. The applicability of this technique for use at KSC has been established and procedural considerations for implementation have been addressed. Experimental evidence based on worst case scenario decontamination processing simulations and reaction characterization has suggested that AKGA can cost effectively function as a drop-in replacement for current neutralizers with minimal modification to existing infrastructure and operating procedures. Further work will be necessary to satisfy permitting requirements and verify that the reaction product stream is non-hazardous in light of limited toxicity data.

Abstract:

This thesis presents research findings on current environmental management practices used by the South African National Defence Force (SANDF). Two case studies are presented; the first is the Grahamstown Military Installation (6 South African Infantry Battalion) and the second the South African Army Combat Training Centre (42 Brigade). A combination of three sampling techniques, namely, the stratified, purposive and link-tracing (snowball) samplings were employed and structured questionnaires and semi-structured interviews with key SANDF officials were used as primary data. In addition, secondary data sources in the form of inter alia the first and second editions of the Environmental Management Plan for Defence (2001 & 2008 respectively); the development and implementation of environmental education and training in the military: a joint United States-Republic of South Africa Environmental Working Group Project (2003); Overarching Strategic Statement for 2011; Integrated Environmental Management Information Series: Linking Environmental Impact Assessment and Environmental Management Systems (2004); The Department of Defence Strategic Plan (2010): Republic of South Africa and the South African Defence Review (2012) were studied. In addition, field observations were also carried out within the two military installations training areas between July, 2011 and November, 2013. Primary data on the conditions of training areas, waste removal after training exercises, pollution prevention measures, and rehabilitation efforts to restore degraded training ranges were collected. Furthermore, composite surface sediment samples and water samples were collected for analysis. A total of fifty-six surface sediments and thirty water samples were analysed for the concentrations of heavy metals using the ICP-MS. These attitudes and perceptions are predominantly positive. Statistical analysis (ANOVA) did not reveal any significant differences in responses, especially, between military ranks. However, sporadic significant differences were found in five of the statements in the questionnaire from respondents with different service periods. Furthermore, the emphasis placed on environmental protection within defence force activities worldwide has compelled the South African Department of Defence and Military Veterans (DoDMV) to regulate the management of the environment within its properties. Yet, these efforts have faced numerous challenges ranging from financial to human resource deficiencies. It was found that environmental management practices and programmes at different military installations vary significantly. Consequently, six environmental management programmes were identified at South African Army Combat Training Centre, while only one environmental management programme was identified at Grahamstown Military Installation. This programme is a collaborative effort between the SANDF/DoDMV and the Department of Water Affairs and Sanitation to eradicate invasive alien plant species. In the light of the analysis of official documents and interviews with respondents, it was established that the DoDMV does not have a budget for environmental management services and environmental management is yet to be incorporated into formal military training programmes. There is a severe shortage of environmentally qualified and knowledgeable personnel within the SANDF. Subsequently, all these drawbacks lead to the failure of the implementation of the Defence Force’s Environmental Management System (EMS) and inadequate management of the environment at military installations of the SANDF. Consequently, these challenges have severely compromised the commitment of the SANDF to honour its environmental management obligations. Such deficiencies tend to undermine the sustainable utilisation of the national assets entrusted to the Defence Force. Therefore, this thesis argues that environmental management programmes for the SANDF are based on a very weak foundation. This thesis proposes an ideal model for the successful implementation of the EMS and management of the environment at SANDF military installations. The analysis of water and soil samples led to the identification and quantification of heavy mental pollutants. The concentrations of heavy metals in water samples were varying between <0.01 to <0.05mg/l, but generally constant. Thus, no significant or meaningful statistical results were obtained. Pearson’s correlation coefficient was used to analyse the concentrations of heavy metals obtained in the sediment samples.

Abstract:

Restoration ecology continues to become ever more relevant as legislation demands we prevent biodiversity losses. Post-industrial restoration sites pose a number of additional challenges, including balancing ecological need with logistical and financial constraints. In the North of Scotland, one such site is the Dounreay Nuclear Power Plant, now undergoing decommissioning. The intention is to restore cliff-top habitat with native vegetation, blending in with its surroundings and necessitating minimal maintenance. The overall objective of this PhD research was to help develop a plan for the restoration of the site. A key challenge in this particular case was the residual low level radioactivity at depth in some areas, and a restoration layer is required to prevent contamination of bioreceptors at the surface, however, topsoil availability is limited. The cliff top site, and exposure to salt spray driven by strong winds, meant the identification of suitable vegetation communities for different areas could be crucial to its success. Vegetation and soil surveys across nine reference sites along the North coast of Scotland identified five non-peat vegetation communities suitable for Dounreay's restoration.

Vegetation and soil surveys across nine reference sites along the North coast of Scotland identified five non-peat vegetation communities suitable for Dounreay's restoration. This prompted the development of a novel concept: that of utilising restoration sites as 'protorefuges' or 'protorefugia', i.e. restoration sites where threatened species at the leading edge of climate change can be translocated ahead of the climate changing. There, they would be joined by individuals of the wider population naturally dispersed as the climate shifts. Overall, these results enabled the development of a refined restoration plan for Dounreay, which takes into account the particular setting, constraints and timelines involved. With the decommissioning of an increasing number of nuclear sites across Britain and Europe taking place in the coming years, this research should be developed further. In particular our novel concept of protorefugia could even be put into practice, benefiting both restoration and conservation.

Abstract:

Type 2 diabetes has reached epidemic proportions in adults and youths. Persistent organic pollutants and endocrine-disrupting chemicals (EDCs), such as pesticides, dioxins, and organochlorines, are omnipresent and persist in the environment with potential for human exposure via contaminated air, waterways, soil, and human food supply. EDCs have been correlated with diabetes incidence and risks. Residential proximity to hazardous waste sites (HWS) has been correlated with increased hospital admission rates for diabetes. The study used a sample population (N = 1,724), ages ≥ 12 years from the 2005-2012 Continuous NHANES and HWS data from the National Priorities List of Superfund Sites. The ecosocial theory of disease distribution, and geocoordinates provided theoretical support. Mann-Whitney U test and binary logistic regression analysis were used to investigate the relationship between residence ≤ 1 mile compared with residence >1 mile from a HWS in NHANES surveyed counties of NJ, PA, NY, and CA on the outcome abnormal A1c ≥ 5.7% while controlling the effect of the moderators: abnormal body mass index (BMI), age, sex, and race/ethnicity on the relationship. Participants with a BMI ≥ 28.95 kg/m2 were 1.8 times and persons ≥ 58 years of age were 2.1 times more likely to have an A1c ≥ 5.7%. Also, non-Hispanic Whites residing >1 mile of a HWS had 82.1 % reduced risk of abnormal A1c compared with the same group residing ≤ 1 mile of a HWS. The results forge opportunities for future studies to consider border distance between residence and HWS. In addition, the results may promote positive social change through diabetes risks education, environmental health education, and practices and raise dialogue about social justice and the geographic distribution of hazardous waste sites.

Abstract:

Nitroglycerin (NG) is a toxic explosive commonly found in soil and contaminated groundwater at old manufacturing plants and military ranges. When NG enters an aquifer, it behaves as a dense non-aqueous phase liquid (DNAPL). Nitroglycerin is an impact sensitive explosive and therefore excavating the area to remove or treat the contaminant can be dangerous. In situ bioremediation and natural attenuation of NG have been proposed as remediation alternatives and it is therefore necessary to understand the degradation mechanisms of NG in contaminated soil and groundwater and investigate the potential for using bioremediation at contaminated sites. Many bacteria have been isolated for the ability to transform NG as a source of nitrogen, but no isolates have used NG as a sole source of carbon, nitrogen, and energy. We isolated Arthrobacter JBH1 from NG contaminated soil by selective enrichment with NG as the sole growth substrate. The degradation pathway involves a sequential denitration to 1,2-dinitroglycerin (DNG) and 1-mononitroglycerin (MNG) with simultaneous release of nitrite. Flavoproteins of the Old Yellow Enzyme (OYE) family capable of removing the first and second nitro groups from NG have been studied in the past and we identified an OYE homolog in JBH1 capable of selectively producing the 1 MNG intermediate. To our knowledge, there is no previous report on enzymes capable transforming MNG. Here we show evidence that a glycerol kinase homolog in JBH1 is capable of transforming 1 MNG into 1-nitro-3-phosphoglycerol, which could be later introduced into a widespread pathway, where the last nitro group is removed. Overall, NG is converted to CO2 and biomass and some of the nitrite released during denitration is incorporated into biomass as well. As a result, NG can be now considered a growth substrate, which changes the potential to bioremediate NG contaminated sites. The magnitude of the effect of biodegradation processes in the fate of NG in porous systems was unknown, and we have been able to quantify these effects, determine degradation rates, and have evidence that bioaugmentation with Arthrobacter sp. strain JBH1 could result in complete mineralization in contaminated soil and sediments contaminated with NG, without the addition of other carbon sources. Site specific conditions have the potential to affect NG degradation rates in situ. Experiments were conducted to investigate NG degradation at various pH values and NG concentrations, and the effects of common co-contaminants on NG degradation rates. Arthrobacter JBH1 was capable of growing on NG at pH values as low as 5.1 and NG concentrations as high as 1.2 mM. The presence of explosive co-contaminants at the site such as trinitrotoluene and 2,4-dinitrotoluene lowered NG degradation rates, and could potentially result in NG recalcitrance. Collectively, these results provide the basis for NG bioremediation and natural attenuation at sites contaminated with NG without the addition of other sources of carbon. Nonetheless, careful attention should be paid to site-specific conditions that can affect degradation rates.

Abstract:

Hazardous waste site remediation cost estimation requires a good estimate of the contaminated soil volume. The United States Environmental Protection Agency (U.S. EPA) currently uses deterministic point values to estimate soil volumes but the literature suggests that probability bounds analysis (PBA) is the more accurate method to make estimates under uncertainty. The underlying statistical theory is that they are more accurate than deterministic estimates because probabilistic estimates account for data uncertainties. However, the literature does not address the problem of selecting an optimal decision point from the interval-valued PBA estimates. The purpose of this study was to identify the optimal PBA decision point estimator and use it to demonstrate that because the PBA method also accounts for data uncertainties, PBA estimates of remedial soil volumes are more accurate than the U.S. EPA deterministic estimates. The research questions focused on determining whether the mean or the 95th percentile decision point is the optimal PBA estimator. A convenience sample of seven sites was selected from the U.S. EPA Superfund Database. The PBA method was used to estimate the remedial soil volumes for the sites. Correlation analyses were performed between the mean and 95th percentile PBA estimates and the actual excavated soil volumes. The study results suggest that the lower bound 95th percentile PBA estimate, which had the best R2-value of 89%, is the optimal estimator. The R2-value for a similar correlation analysis using the U.S. EPA deterministic estimates was only 59%. This confirms that PBA is the better estimator. The PBA estimates are less contestable than the current U.S. EPA deterministic point estimates. Thus, the PBA method will reduce litigation and speed up cleanup activities to the benefit of the U.S. EPA, corporations, the health and safety of nearby residents, and society in general.

Öffentlich Private Partnerschaften (PPP) werden als Mittel zur Mobilisierung brach liegender Grundstücke thematisiert. Eine zentrale Rolle spielt der Begriff der „Initialbrachfläche“. Erfährt die Initialbrache einen öffentlichen Nutzungszweck mit Hilfe einer PPP, hat dies positive Auswirkungen auf benachbarte Brachen in einem definierten Umfeld. Am Beispiel des Chemnitztales mit seinem hohen Brachenbestand wurde ein PPP Projekt konzipiert. Es wird weiterhin eingegangen auf Aspekte privaten und privatwirtschaftlichen Engagements für Altstandorte und Brachen, z.B. unter dem Schlagwort Corporate Social Responsibility. Darüber hinaus wird die naturschutzrechtliche Eingriffsregelung angesprochen: Ausgleich für Flächeninanspruchnahme soll künftig verstärkt zugunsten der Renaturierung von Altstandorten erfolgen. Schließlich wird die technische Neuentwicklung eines Geokunststoff Gabions vorgestellt, bei dem Bauschutt aus Flächenrecyclingprojekten als Füllmaterial eingesetzt wird. Als Einsatzbereich des transportablen Geokunststoff Gabions wird ein mobiles Hochwasserschutzsystem skizziert.

Abstract:

In this thesis I estimate a monetary value of the risk attached to living near a hazardous waste

site in the town of Teckomatorp. This site is the result of hundreds of rusty leaking barrels of

toxins being buried in the ground by the company BT Kemi in the 1970’s. Ever since then the

site has been remediated in several steps and is still contaminated today. For estimating the

perceived risk of living near this site I use a hedonic price model (HP) which is a form of a

revealed preference approach. In a HP model the price of a market good is a function of

different utility-bearing characteristics and the estimated parameters can be used to calculate

the implicit prices of these characteristics. In this case I use a data set from the National

Swedish Institute for Building Research (IBF) and regress property price on a number of

housing characteristics. I compare an estimated town-effect for Teckomatorp with the

estimates for two control towns: Billeberga and Anderslöv. I can confirm my hypothesis that,

after controlling for housing characteristics, there is a negative effect on prices of property in

Teckomatorp. I find that property prices are on average 46878 SEK lower in Teckomatorp

than in the two control towns.

Full text

Abstract:

Hazardous waste sites and aging wastewater infrastructure are common in the United States. There are hundreds of thousands of contaminated sites and more than a million miles of sewer pipes. Populations living close to hazardous waste sites often suffer from increased risk of adverse health effects due to exposure to contaminated environmental media. Vapor intrusion is one process by which nearby populations can be exposed to volatile organic compounds (VOCs). Aging wastewater infrastructure is important for vapor intrusion site assessments because sewer pipes can serve as preferential vapor transport pathways. Near contaminated sites, pipe deterioration allows migration of contaminants into sewers and potential accumulation of chemical vapors in sewer gas and nearby buildings. The objectives of this study are to develop a screening-level method to identify contaminated sites where additional evaluation of vapor intrusion is necessary, and then conduct field sampling at these sites to investigate sewers as potential vapor intrusion pathways. Sampling was conducted at four study sites, which consist of former and current dry cleaning facilities located in Lexington, Kentucky. The results of this study demonstrate that preferential vapor intrusion pathways such as sewers can facilitate the spread of vapor intrusion exposure risks beyond source areas of contamination.

Abstract:

Thesis is submitted in partial fulfilment for the degree of Master of Architecture to the Faculty of Engineering and the Built Environment, School of Architecture and Planning at the University of the Witwatersrand, Johannesburg, 2018
This thesis aims to understand the role that Independent Power Producers (IPP’s) can play in the renewal of architectural firms in creating new realities and how these firms can once again become drivers of social change. Kathu (Northern Cape), a steel mining town, is facing the reality that it will have to survive without a mining house and the community funding that results from its operations soon. There are three IPP’s within a 50km radius of Kathu. Under the current funding structure all 3 IPP’s have to contribute to socio-economic development (SED) and enterprise development (ED) within Kathu. According to the Independent Power Producers Procurement Programme (IPPP’s), IPP’s are required to provide 1% of gross turnover to community funds for SED and ED development programmes. Where this funding differs from funding obtained from mining houses is that renewable energy is effectively limitless. Despite IPP’s having a projected lifespan of 20 years they will continue to be redeveloped and upgraded. These upgrades will allow for longevity of revenue, which in turn allows for sustained support for the communities surrounding them. Funding structures that are being used to disseminate mining house funds to the communities are suffering from governance issues. This means that the communities do not receive the most effective or necessary forms of development. Through a new typology of architectural practice, the way these funds are managed and utilised can create better environments for those communities. This new typology of architectural firm must move away from the corporate and profit driven nature of modern architectural firms and more towards a ‘Rural Studio’ model. This is where the primary focus is on the community and how to best serve the needs of the people. In doing so SED projects would be more effective in bringing about social change, creating new realities for communities and drivers of sustainability in post-mining towns in South Africa.
