Abstract

A bioelectrochemical system device may be used to enhance groundwater pollutant chemical removal or degradation. Such a bioelectrochemical system may be inserted into the environment to be remediated through a variety of techniques, such as through insertion into wells or other access points, trench insertion, direct insertion, borehole insertion, or combinations thereof. In some aspects, the bioelectrochemical system device may have a hollow-tube configuration with an outer ring anode and inner ring cathode. In further aspects, the bioelectrochemical system device may have a modular form that can be combined with multiple other modules such one or more bioelectrochemical system devices.
