CVES Resistivity Investigations for Optimizing Groundwater Protection at Highway Construction

På svenska

Author

Summary, in English

CVES resistivity has been used to achieve a continuous image that reflects the hydraulic properties of the ground along a road stretch. The purpose was to map the vulnerability for pollutants to penetrate into the precious groundwater magazine under the Kristianstad plains. The investigation shows that a large part of the area is covered by impermeable layers in the form of a thick clay till. Large parts of the area is covered with sandy till over clay till, and this sequence has been determined to have a permeability that gives sufficient protection of the aquifer below. In parts of the area, close to the Linderöd horst where soil cover is thin or non-existent and at the glaciofluvial deposits at and around Helgeåsen it is motivated to construct the road so that the ground water is protected. In about 10 % of the investigated area it will be necessary to perform further investigations to define the need of groundwater protection as part of the road design.
