Biochar effectively sorbs organic contaminants such as trichloroethylene and tetrachloroethylene. Therefore, it is a potential low-cost option for soil and water remediation. Depending on the target compound, biochar properties could be tailored through the selection of different feedstock materials to fit the contaminant of interest.
Major drinking water source of Dhaka city is endangered by the Cr pollution from approximately 150 tanneries in Hazaribagh area, in the western side of the capital. Groundwater, surface water and pore water samples, as well as borehole soil samples, were collected in 2012-2013 in order to assess the situation and to describe the Cr behaviour in the soil and groundwater.
FREEWAT was a HORIZON 2020 project financed by the EU Commission under the call WATER INNOVATION: BOOSTING ITS VALUE FOR EUROPE. The main result of FREEWAT is an open source and public domain GIS integrated modelling environment (the FREEWAT platform) for the simulation of water quantity and quality in surface water and groundwater with an integrated water management and planning module.
Taihu Lake surrounding is one of the most developed regions in China. Thus the serious contaminant input is causing the problems in the lake ecosystem. The aim of the current project is to demonstrate and adopt German water technologies and management concepts in the area.
A training network for enhancing the understanding of complex physical, chemical and biological process interactions in the hyporheic zone was formed in frames of Marie-Skłodowska-Curie program. In our laboratories, a batch and column experimental setup are used to study the sorption of micropollutants to hyporheic biomass in order to gain a mechanistic understanding of sorption processes in the hyporheic zone.
Managed aquifer recharge (MAR) is an emerging technology for recharging depleted aquifers using alternative water sources. One of our tasks within the MARSOL project was to perform column experiments simulating MAR to investigate water quality changes when treated wastewater is infiltrated through soil from a possible future MAR site in Greece.
Naturally occurring hydrocarbons in the soil are affecting the environment and the health of the people, who live in Kirkuk region in northeast Iraq. A current project examines the effect of natural hydrocarbon seeps and oil brine seeps on surface water, groundwater and as well as physical and chemical properties of soil.
