Electro-bioremediation of nitrate and arsenite polluted groundwater.

The coexistence of different pollutants in groundwater is a common threat. Sustainable and resilient technologies are required for their treatment. The present study aims to evaluate microbial electrochemical technologies (METs) for treating groundwater contaminated with nitrate (NO) while containing arsenic (in form of arsenite (As(III)) as a co-contaminant.
