Evaluating Microbial Transport in Saturated Aquifers for Greywater Reuse through Integrated Experiments, Modeling, and Risk Assessment

ABSTRACT

This project aims to evaluate microbial transport in saturated aquifers as part of greywater reuse initiatives, focusing on public health concerns related to groundwater contamination. It is divided into three main components: laboratory experimentation, simulation modeling, and risk assessment. The lab work involves studying microbial transport in controlled environments, while simulations (possibly using tools like MODFLOW) predict real-world impacts on groundwater. Risk assessments evaluate the potential public health risks associated with greywater reuse, particularly in spray irrigation systems, factoring in pathogen exposure through inhalation and other means.

Some Important results

Seasonal risk of exposure to L. pneumophila

In conclusion, this project provides a comprehensive assessment of microbial transport in aquifers for greywater reuse, addressing critical public health concerns. Through a combination of laboratory experiments, simulation modeling, and risk assessment, the study aims to bridge knowledge gaps in groundwater contamination and inform safe water management practices. The results highlight the potential risks associated with microbial contamination in greywater reuse, particularly through spray irrigation, and emphasize the importance of careful monitoring and mitigation strategies to protect public health.
