IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Technology of Groundwater Treatment in the Aquifer for Drinking Water Supplies
Author : Valery V. Kulakov
The technology of subsurface iron and manganese removal (in situ) is the saturation of groundwater by oxygen of air. As result, biogeochemical zones (barrier) are formed, and iron and manganese are oxidized and remained in aquifer. Besides, such barrier prevents the entry of potentially hazardous contaminants transported with the river filtrate. Organic substances in the river filtrate are transformed by biogeochemical processes to carbon dioxide and water in the contact zone "river bottom sediment-aquifer" and during moving inside the aquifer. Despite a complex hydrochemical composition of the Tungus groundwater site (Khabarovsk, Far East of Russia) concentration of iron and manganese were reduced to below the normative values without the use of reagents and bulky ground facilities.
