There are many reasons for finding manganese at levels above action levels in soils and groundwater. There are anthropogenic and non-anthropogenic sources. In the case of non-anthropogenic, the hydrogeology plays an important role, as noticed in the article. As far as anthropogenic sources, historical land use plays a critical role as well as well construction (i.e. well casing materials).
