Sustainable groundwater abstraction. Review report

GEUS and six Danish water companies have established collaboration with the long term goals of enhancing the scientific foundation for assessment of sustainable groundwater abstraction and contributing to an improved knowledge based water management practice in this field. The present report is the first output of this collaboration.

The report has been prepared between October 2012 and March 2013 by Hans Jørgen Henriksen and Jens Christian Refsgaard. The work has been financed by the six water companies with a Steering Committee comprising

- Troels Kjærgaard Bjerre, Vandcenter Syd (formand)
- Anne Scherfig Kruse, HO-FOR
- Jørn-Ole Andreasen, Aarhus Vand
- Charlotte Schmidt, TRE-FOR Vand A/S
- Peter Madsen, Esbjerg Forsyning
- Per Grønvald, Aalborg Forsyning

The report was subject to peer review by two international experts

- Dr. Mike Dunbar, Environment Agency, UK. Mike Dunbar is a recognized expert in environmental flow.
- Professor Roland Barthel, University of Gothenburg, Sweden. Roland Barthel is a recognized expert in aquifer safe yield.

The project progress has been discussed at a kick-off meeting and two workshops with participation of the Steering Committee plus the following additional persons (some participated in only one of the workshops)

- Jens Rasmussen, HO-FOR
- Christian Ammitsøe, Vandcenter Syd
- Michael Rosenberg Pedersen, Aarhus Vand
- Ole Silkjær, TRE-FOR
- Eva Hansson, Roskilde Forsyning
- Mads Kjærstrup, Ringkøbing-Skjern Forsyning
- Bo Lindhardt, Nordvand
- Claus Vangsgaard, DANVA
- Henrik Nielsen, Naturstyrelsen
- Martin Skriver, Naturstyrelsen
- Dirk-Ingmar Müller-Wohlfeil, Naturstyrelsen
- Niels Philip Jensen, Kommunernes Landsforening
- Martin Olsen, GEUS
- Anker Lajer Højberg, GEUS

The first workshop on 12 December 2012 focussed on basic concepts and preliminary results. The international peer review was presented by the two reviewers and discussed at the second workshop on 7-8 February 2013, which made conclusions on necessary modifications and improvements of the report that have been implemented in the present final version.
