PRESS RELEASE: Danish model used to find water in India

The CSIR-NGRI (CSIR-National Geophysical Research Institute of India) in collaboration with Aarhus University has subcontracted SkyTEM Surveys of Denmark to map aquifers in six strategically selected areas of India beginning in March 2013. The objective of Aquifer India Mapping Project (AQUIM) is to acquire 13,800 line kilometres of airborne geophysical data and apply advanced data processing techniques in order to assess a Danish helicopter borne technology for aquifer mapping in the country.

The study is being managed under a collaborative research program between CSIR-NGRI in India, the HydroGeophysics Group, Aarhus University in Denmark as well as the Ministry of Water Resources, Government of India. The airborne data is being collected to locate the aquifers in order to assess their status and their vulnerability to human activities. There is a strong need to design effective management programs for aquifer systems worldwide and to respond to that need a thorough knowledge of the various aquifer systems, including their volume and dimensions, is required.

Flemming Effersø, SkyTEM’s CEO reported that “India needs to ensure a clean water supply to over 1 billion people and are using the Danish model and method for mapping much needed fresh water resources so that they can be protected now, and for future generations.”

About SkyTEM Surveys

SkyTEM is a helicopter borne geophysical system designed in Denmark in the late 1990s specifically to map water resources. SkyTEM is recognized as an advanced airborne technique for aquifer mapping as well as for mapping other buried resources. The method has been employed to map groundwater in Antarctica, Australia, Canada, the USA, Thailand and several European countries. The SkyTEM method delivers accurate high resolution images of the earth’s subsurface and is used worldwide to map mineral resources and to collect earth data critical for geotechnical and environmental engineering projects.

About Aarhus University

The HydroGeophysics Group (HGG) of Aarhus University conducts high level research and development of geophysical methods for hydrogeophysical and hydrological mapping. The group supports the ongoing national mapping of groundwater resources in Denmark and also works with research partners overseas. HGG has developed highly sophisticated data processing techniques for geophysical and geological applications together with a number of novel instruments for geophysical measurements.

About the National Geophysical Research Institute

CSIR-National Geophysical Research Institute (CSIR-NGRI), a constituent Laboratory of CSIR, was established in 1961 with the mission to carry out research in multidisciplinary areas of Earth Sciences. The Institute plays a pivotal role in the exploration of Hydrocarbons, Mineral and Groundwater resources in addition to studies in Engineering Geophysics, Seismology, Geo Dynamics and Geo Environment. The Institute has carried out a large number of projects both at national and international levels including its contribution to the national program of Technology Mission on drinking water. The CSIR-NGRI is an internationally reputed organization carrying out state-of-the-art research with unique collaborations such as establishment of an Indo-French Centre for Groundwater Research and a similar centre with Denmark in the pipeline.
