Kazakhstan (the example r Ilek) Summary: Provides a comparative description of technological solutions for cleaning
groundwater river valley. Ilek from hexavalent chromium and boron modern methods
geotechnologies on materials made LLP "health center and Ecodesign" in 2008-2009. feasibility
studies and analysis of the results of pilot experiment in 2013 to clean up groundwater from
hexavalent chromium. Need to take measures to clean up groundwater and boron stresses the
danger of contamination with boron sludge reservoir Aktobe that releasing adsorbed boron at
high water releases contaminate water intakes of drinking water values. Provides payment
