The BGS has been involved with research into the hydrogeology and hydrogeochemistry of arsenic in a number of high-arsenic aquifers across the world.
This work has been funded by a number of organisations, including the UK government's Department for International Development, NERC, World Bank, Danida and Unicef.
Investigations have been carried out in areas with naturally occurring arsenic contamination and in areas where mining has altered groundwater systems.
