IN-GROUND: Inexpensive monitoring of Groundwater pollution in Urban African Districts


This NERC sponsored international collaboration between researchers in Tanzania and the United Kingdom will develop and test an inexpensive microbial fuel cell biosensor, for the on-site, real time, monitoring of urban groundwater quality. The biosensor will be able to detect water pollution emanating from different sources such as pit latrines. The project will focus on monitoring urban areas, as latrine coverage and the related groundwater pollution affects, proportionally, more people than in rural areas. It is estimated that 70% of urban settlements in Tanzania are unplanned. The problems of urban unplanned areas include lack of centralised sewerage and the inaccessibility of emptying services for onsite technologies.
