Groundwater Remediation: Dichloromethane Time Series Analysis and PFOA Permeable Reactive Barrier Simulation

❮ ❯

Summary: This report showcases advanced analytical and simulation skills applied to environmental remediation. Utilizing R statistical software, a time series analysis of dichloromethane (DCM) in groundwater revealed a significant negative trend and a 99% reduction in concentrations, indicating improved groundwater quality. Complementing this, I developed and simulated groundwater remediation scenarios using HYDRUS-1D software, focusing on perfluorooctanoic acid (PFOA) removal with a zero-valent iron permeable reactive barrier (ZVI-PRB). This simulation confirmed ZVI-PRB's high effectiveness, decreasing PFOA concentrations below Australian health guidelines within 300 days. The project outcomes underscore proficiency in environmental data analysis, statistical modeling, and contaminant transport simulation, offering key insights for ongoing and future remediation strategies.
