13th International UFZ-Deltares Conference on

Sustainable Use and Management of Soil, Sediment and Water Resources

9–12 June 2015 • Copenhagen, Denmark

Tour 1A: Sustainable exploitation of natural resources - Securing high quality drinking water and natural resources for Copenhagen and creating recreational facilities for the community at the same time


1’st stop Kallerup Gravelpit

Kallerup Gravel pit is situated in the socalled Hedeland Region, which is the largest system of Gravel pits in Denmark mainly supplying the capital region of Denmark with essential raw material (gravel, sand and limestone) for constructing buildings, roads, tunnels, etc. The Kallerup Gravelpit offers unique views of the complex geological setting most of Denmark is situated on. Namely glacial deposits and prequaternary marine settings like the limestone basement. We will be looking at the clay till covering the glaciofluvial sand and gravel, and discuss the potential for contaminant transport through these types of geneally low permeable deposits.


2’nd stop Hedeland

The Hedeland Area is famous for reestablishing former gravel pit areas. Today the former wasteland is transformed into a recreational area containing: plains, forest, fishing lakes, skiing resorts, Golf courts, racing tracks, open air theaters, and even a railroad with oldfashion steam engines is transporting tourist around.

 We will visit the open air theater and give a presentation on an example of how large “wounds” in the landscape may be transformed into a highly recreational area.


3’rd stop Lejre water works

The area near Lejre provides an excellent example of the sustainable management and protection of the Danish groundwater resources. In addition to groundwater for the municipalities own drinking water, the area of Lejre exports about 6 million m3 of water on a yearly basis to Copenhagen and its surrounding communities. The heavy abstraction has impacted the groundwater resources, streams and freshwater ecosystems in the area. At this stop the cooperation on the management of groundwater resources at the national and municipal level will be discussed. The different roles will be presented, with The Danish Nature Agency describing their role as assessment of what actions need to be taken, Lejre Municipality describing their role in designing and administering the action plans, and HOFOR (supplier drinking water to Copenhagen) describing how they are involved in implementation of the action plans.
