Career Summary

Biography

As an early career researcher the resultant publication outputs have been lower than expected due to both the logistics involved in the research and the nature of large scale experimental research. For example, an entire research facility had to be built before any experimentation could begin. The design and construction of the Georemediation Research Facility took approximately two years to complete as stringent NSW EPA guidlines had to be met before conscent was given to build the facility. The Georemediation Research Facility, which is a key part of the Priority Research Centre for Geotechnical and Materials Modelling, was established in 2005 with funding from Hydro Aluminium as an extension of an existing linkage project worth approximately $1.0M since 1998. The facility will eventually provide information on innovative technologies for the remediation of contaminated soils and groundwater and plays a major role in the Centres funding profile. Since there is no equivalent facility available nationally, this project will ensure the University of Newcastle remains at the forefront of environmental engineering research and practice. Pilot scale experimental testing has also been slow to progress due to the current drought. With little rainfall over the last three years, extracting the necessary volumes of contaminated groundwater from the industry partner (Hydro Aluminium) site has been very slow with only 21 kL extracted in 2 years when approximatley 120 kL was expected initially. Research Expertise
Research expertise consists of laboratory and field work in the area of Environmental Engineering with a specific focus on groundwater, geochemistry and water pollution. Research into new technologies to remediate inorganic contamination (heavy metals, fluorides, cyanides etc) of aqueous media and the development of geochemical models to aid in design and implementation of the new remedial technologies are investigated.

Teaching Expertise

Copyright © 2015 Published by Elsevier B.V. All rights reserved. Industrial wastewaters often consist of a complex chemical cocktail with treatment of target contaminants complicated by adverse chemical reactions. The impact of metal ions (Cd<sup>2 +</sup>, Ba<sup>2 +</sup> and Mn<sup>2 +</sup>) on the kinetics of fluoride removal from solution by natural zeolite was investigated. In order to better understand the kinetics, the pseudo-second order (PSO), Hill (Hill 4 and Hill 5) and intra-particle diffusion (IPD) models were applied. Model fitting was compared using the Akaike Information Criterion (AIC) and the Schwarz Bayesian Information Criterion (BIC). The Hill models (Hill 4 and Hill 5) were found to be superior in describing the fluoride removal processes due to the sigmoidal nature of the kinetics. Results indicate that the presence of Mn (100 mg L<sup>- 1</sup>) and Cd (100 mg L<sup>- 1</sup>) respectively increases the rate of fluoride sorption by a factor of ~ 28.3 and ~ 10.9, the maximum sorption capacity is increased by ~ 2.2 and ~ 1.7. The presence of Ba (100 mg L<sup>- 1</sup>) initially inhibited fluoride removal and very poor fits were obtained for all models. Fitting was best described with a biphasic sigmoidal model with the degree of inhibition decreasing with increasing temperature suggesting that at least two processes are involved with fluoride sorption onto natural zeolite in the presence of Ba.

© 2015 Elsevier Ltd. All rights reserved. Groundwater contaminated with spent pot liner leachate (SPLL) was treated with calcite (CaCO3) and CO2 in a series of free drift batch reactor kinetic experiments with the aim of optimizing fluoride removal. In order to better understand the reaction kinetics for SPLL, the pseudo-second order (PSO), four and five parameter Hill (Hill 4 & Hill 5) models were applied to observed fluoride removal as a function of CO2 partial pressure and stirring rate. To account for differences in the number of model parameters, model fitting was compared using the Akaike information criterion (AIC), the Schwartz Bayesian information criterion (BIC) and the statistical F-test. In every case, the best fitting model order was found to be Hill 5 > Hill 4 > PSO due to the ability of the Hill models to accommodate sigmoidal kinetics. Removal of fluoride from SPLL under atmospheric CO2 conditions was found to be inhibited with no removal occurring for the first 3000 min with the inhibition times, based on the reaction half-life, reducing with increased CO2 partial pressure and stirring rate. X-ray diffraction (XRD) analysis revealed that the residual solid filtrate consisted of trona (Na3(CO3)(HCO3)·2H2O) a potentially valuable mineral kogarkoite (Na3SO4F) and fluorite (CaF2) accounting for fluoride removal, and unreacted calcite (CaCO3).

Free-drift batch reactor experiments using calcite (limestone, CaCO 3) were used to study fluoride removal through precipitation as fluorite (CaF2) from solutions with concentrations reflective of an industrially contaminated site. The influence of CO2 partial pressure (pCO2), stirring rate, and fluoride concentration were investigated in this paper. Equilibrium modeling shows that in wastewaters with high fluoride concentrations (~2,000 mg/L), the flux of CO2(g) to CO 2(aq) could not keep up with the consumption of CO2(aq), resulting in an initial disequilibrium with experimental pH reaching equilibrium quickly, while fluoride removal lagged. Increasing stirring rate significantly decreased the extent of disequilibrium and the time at which the CaCO 3-fluoride-CO2 system attained equilibrium due to the increased rate of transport of dissolved CO2 to the CaCO3 surface, and simultaneously the rate of transport of the dissolved CaCO 3 to the bulk solution. Optimal fluoride removal occurs at pCO 2~10-0.52 [30% (mol% CO2)] with 96% of the initial 2,000 mg/L fluoride load removed in less than 80 min with a stirring rate of 300 revolutions per minute. Increasing pCO2 to ~100 (100% CO 2) resulted in very little gain, less than 2%, in fluoride removal, or in the time required to reach equilibrium and therefore significant remediation cost savings can be obtained by using pCO2 30% when compared to 100%. © 2013 American Society of Civil Engineers.

This paper reviews methods for understanding, assessing and controlling the exposure of workers to airborne contaminants while involved in the remediation of contaminated sites. Contaminants reviewed include asbestos, the oxides of chromium, beryllium and silica. Initial assessment should involve the collection of information on the types of contaminants present, their form and likely concentrations as well as their toxicity and exposure pathways. Measures are then considered for minimising exposure.
