ABSTRACT
The paper presents a residue-free kind of water treatment process for the removal of metals like arsenic, iron and manganese and other water constituents like ammonia which may deteriorate drinking water quality. In this process the underground body, i.e. the aquifer, is used as a natural reactor. The results of field experiments of two technical-scale in-situ groundwater treatment plants are reported.
