PhD Candidate, Civil and Environmental Engineering
University of Waterloo

Andrea Marrocco is currently pursuing a PhD degree in the Department of Civil and Environmental Engineering at the University of Waterloo, with an emphasis on groundwater remediation. Her research is focused on better understanding the effectiveness of carbon based injectate (CBI) technology by investigating the relationship between (1) the sorption of petroleum hydrocarbons (PHCs) in groundwater to activated carbon, and (2) the anaerobic microbial biodegradation of sorbed mass to facilitate AC regeneration and sustained, long-term PHC sorption. Andrea received a Bachelor of Science in Environmental Sciences from the University of Guelph and an Honours Diploma in Environmental Technology from Georgian College. She has worked for industry and government agencies in the field of contaminant hydrogeology and groundwater resource management.


Carbon Based Injectates for the Treatment of Petroleum Hydrocarbons in Groundwater

Carbon based injectate (CBI) technology is gaining attention as a remediation solution for contaminated groundwater and involves the interplay between sorption of groundwater contaminants to activated carbon and microbial biodegradation. Our work aims to provide a clear understanding of CBI’s potential for the remediation of aqueous petroleum hydrocarbons (PHCs) in anaerobic environments. To accomplish this, a series of batch and column experiments and a pilot scale field trial are being performed. Batch experiments are used to determine sorption isotherms and kinetics for several PHCs, as well as the rate of anaerobic PHC biodegradation by indigenous and cultured microbial consortia. Column experiments are used to mimic field conditions and explore: microbial community dynamics, biofilm development, and CBI performance with variable PHC loading. The field trial will provide an enhanced understanding of CBI performance under natural environmental conditions. This presentation will include an overview of the research project and key findings to date.
