My dissertation addresses how engineers, scientists, and bureaucrats generated knowledge about pollution, crafted an institution for environmental protection, and constructed a collective identity for themselves. I show an important shift in regulators\' priorities, from stringent health-based standards to flexible technology-based ones through the development of end-of-pipeline pollution control devices, which contributed to the emergence of economic incentives and voluntary management programs. Drawing on findings from archival documents, published sources, and oral history interviews, I examine the first decade of the EPA amid constant organizational changes that shaped the technological and managerial character of environmental policy in the United States. Exploring the EPA\'s internal research and development processes and their relationship with scientific and engineering communities sheds light on how the new fields of environmental engineering and policy were co-produced in the 1970s.
I argue that two competing approaches for environmental management, a community health approach and a control technology approach, developed from EPA\'s responses to bureaucratic, geographical, and epistemic challenges. I focus on researchers and managers from the Office of Research and Development at Research Triangle Park, North Carolina, as they were engaged in (1) controversy about integrated aerometry and epidemiology research intended to correlate air pollution and health, (2) intra-agency debate about the government\'s responsibility for introducing catalytic converters for tailpipe emissions reduction and responding to the potential environmental and social consequences, and (3) inter-agency activities for the demonstration of scrubbers for smokestack emissions and further application of the control technology approach in energy-related environmental problems.
My principal conceptual contribution is "regulatory engineering." I define regulatory engineering as an approach to sociotechnical problems in which engineering practices are incorporated into regulatory and organizational changes, which in turn influences technical knowledge and identity formation. As EPA activities became closely associated with energy and economic issues toward the end of the 1970s, I argue that engineers took the initiative in demonstrating and evaluating control technologies for pollution abatement and energy development, scientists carefully studied environmental and health effects of these technologies, and regulators set up pollution standards and attainment deadlines accordingly. Studying the co-production of knowledge, institution, and identity through the lens of regulatory engineering helps us to understand technoscientific and managerial aspects of environmental governance beyond the 1970s EPA where technical feasibility considerations, economic incentives, and cooperative management expanded into legislation and regulation.

Environmental engineering is a relatively new engineering discipline. The engineering profession increasingly recognises the importance of engineers moving from their traditional stereotypical technical focus and becoming broader skilled and more responsive to society's needs, particularly regarding the environment. This is often encapsulated as the new engineer. Environmental engineers should be well placed to make a significant contribution to this goal. The nature of engineers and engineering is briefly discussed before tracing the evolution of environmental engineering. This new branch of engineering has evolved from the earlier dominance of sanitary or public health engineering and now incorporates a broader, holistic approach to the solution of environmental issues. A literature review is presented on society~s awareness and concern with the environment. This leads to an investigation of the relationship between engineers and the environment. A review of environmental engineering education follows. The education of engineers to improve their environmental credentials is contentious. A common theme is that all engineers require a better environmental education. However, there is less consensus regarding the need for separate environmental engineering degrees at undergraduate level. Despite this, environmental engineering degrees have proliferated in Australia in the past decade. Yet little is known about the graduates and their transition into an engineering profession which is largely founded in traditional engineering values. This research addresses the lack of knowledge about environmental engineers. Using a number of concepts from sociology, particularly professional socialisation, a theoretical framework was developed to suggest what environmental engineers may experience both as students and in professional practice. This theoretical framework was tested using a case study of forty-four recent graduates from the School of Environmental Engineering's undergraduate degree in environmental engineering at Griffith University in Brisbane, Australia. This environmental engineering degree is considered unique in this country because of its breadth and diversity of subject material, which is underpinned by the host school's location in the Faculty of Environmental Sciences. This contrasts with the common approach of either slightly modifying existing civil engineering degrees to produce an environmental strand or creating a hybrid environmental engineering degree through combinations of other engineering programmes. In both these cases, the environmental engineering is normally located in an engineering faculty and is thus more influenced by traditional engineering values.
The research in this thesis is qualitative in nature. This approach was adopted to ensure a rich picture emerges of the professional socialisation of enviromnental engineers. The data presented are based on interviews with the graduate environmental engineers and follows the graduates chronologically through university and into professional practice. Environmental engineering students enter university with considerable diversity of knowledge, interest and commitment. The degree programme exerts a strong socialising influence in raising environmental awareness and capabilities. However, the outcome is not uniform and a number of socialisation failures can be identified, particularly where graduates are concerned about their identity and lack confidence as engineers at the end of their studies. The path to professional socialisation as environmental engineers is further influenced by the widespread lack of recognition of the qualifications and capabilities of environmental engineers in the profession and employment. Professional socialisation also varies considerably with the diversity of employment situations. In general, the process of organisational socialisation into the norms of an employment culture is stronger than the socialising influences of the profession. Socialisation is also affected by individualism. Thus, overall there are a spectrum of professional socialisation successes and failures.
Environmental engineering is plagued by considerable uncertainty as to its nature. This is apparent throughout the engineering profession and employer organisations. This uncertainty has a significant impact on environmental engineers and consequently many are unsure regarding their identity as engineers.
Despite the uncertainties regarding identity and professional socialisation, the generalist skills, environmental commitment and capabilities, and social responsiveness of many of the environmental engineering graduates typify the attributes of the new engineer. A minority could not be considered as meeting these attributes, particularly where they identify more strongly with traditional engineering values. However, on balance, it is evident that environmental engineers are making a significant contribution to the paradigm change that the engineering profession must make to better reflect societ~s needs and aspirations. The thesis concludes with a range of recommendations designed to indicate areas of further research to complement and extend this study.

The approach to addressing many environmental problems requires a strong foundation in chemical science and engineering. A prime example is the developing subject of environmental engineering, where a multidisciplinary field is led by chemists and chemical engineers. This thesis presents a collection of research publications, which are of both an applied and multidisciplinary nature, primarily directed towards developing technology for energy and environmental sustainability. This has included the development of sensors for in-situ environmental monitoring and the application of nanocrystalline semiconductor photocatalysts for treatment of air, waste and potable waters. The development of laser processing methods for catalyst production and modification and the design and assessment of advanced photocatalytic reactors is also presented. Research on the reduction of carbon dioxide to fuel products is also considered. Real time in-situ sensors for environmental monitoring are an area that has seen a significant growth over the past twenty years. In this thesis, I detail my research into optical and electrochemical sensors for detection of organic chemicals and heavy metals in both the marine environment and in contaminated land. The other key research theme is the topic of water remediation using semiconductor photocatalysis. This has included treatment of industrial effluent, drinking water and water used in aquaculture. In particular, I have led research on the photocatalytic removal of cyanotoxins in water, a technique pioneered at RGU. These highly toxic chemical metabolites of cyanobacteria have been responsible for the deaths of animals and humans through ingestion of contaminated water.

This research investigated the adsorption mechanisms of hydrophobic chlorinated contaminants in mineral micropores and on iron metal surfaces. Activated adsorption and desorption of trichloroethylene (TCE) in mineral micropores was studied using experimental and molecular modeling techniques. Adsorption of TCE on a silica gel adsorbent was measured using a frontal analysis chromatography technique at atmospheric and elevated fluid pressures. The results showed that the increase in pressure was able to rapidly induce the formation of a desorption resistant fraction. Grand Canonical Monte Carlo (GCMC) modeling was used to elucidate the nature of water and TCE behavior within silica micropores. TCE adsorption was energetically most favorable in pores that were minimally large enough to accommodate one TCE molecule. A molecular level study of the interactions between hydrophobic chlorinated contaminants and sediments was performed. GCMC simulations were preformed to investigate water and TCE adsorption in slit micropores confined by charged and uncharged silica surfaces. Gas-phase single-sorbate simulations with water or TCE were performed as well as mixture simulations of bulk water containing TCE at 1% of its saturation concentration. Aqueous-phase TCE at a concentration equal to 1% of its saturation concentration was able to completely displace adsorbed water in uncharged pores. In highly hydrophilic pores, TCE at this concentration was able to displace up to 50% of the adsorbed water. Metallic iron filings are becoming increasingly utilized as reactive agents for reductive dechlorination of solvents in contaminated groundwaters. This research also used molecular modeling to study chemical adsorption of TCE and PCE to iron surfaces. Quantum mechanical calculations were performed to determine the thermodynamic favorability and resulting structures for chemical adsorption of TCE and PCE to iron surfaces. Molecular mechanics modeling was used to study the effects of atomic hydrogen on the thermodynamic favorability for chemically adsorbed TCE and PCE. Because TCE and PCE react with iron surfaces, their adsorption to iron cannot be investigated experimentally. This makes molecular modeling approaches a useful complement to experimental investigations of chemical reaction phenomena.

A large-scale experimental, state of the art storage facility was constructed on the Macdonald Campus of McGill University. This storage facility will serve as a tool to further investigate many of the laboratory experiments performed in agricultural and food science topics, by providing a representation of actual storage facilities in use in the industry today. The storage facility was fully instrumented to provide valuable data of the stored commodity and it's environment. A custom control software was developed with a user friendly graphical interface. This fully automated software allows data acquisition and control of temperature and relative humidity of the experimental storage facility. Experiments were performed and the control software provided an adequate temperature and relative humidity control. The controller was based on a conventional PID or proportional, integral and derivative controller. To further improve the control of the storage facility, a novel multivariable PID controller was developed using enthalpy as the process variable, which encompasses both temperature and relative humidity. The novel controller was tested using a mathematical model developed. Simulations were performed comparing the performance of the novel multivariable controller to two other conventional controllers. The results demonstrate that the novel multivariable PID controller is capable of controlling temperature and relative humidity better than the other two conventional control techniques.
