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 exa

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

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 nanocrystallin

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

The goal of this dissertation was to examine transport of gas-phase contaminants and the processes causing nonideal transport. With one exception, all experimental work was performed with synthetic porous media (glass beads). I performed experiments with methane, trichloroethene, benzene, and toluene. Transport experiments for gas-phase contaminants in dry homogeneous and heterogeneous porous media were performed to study dispersion of gases during transport. Axial diffusion was found to be a primary contributor to dispersion at gas velocities < 20 cm min⁻¹. Conversely, mechanical mixing was t
