In connection with the detailed planning of new double track railway tunnel approx. 23.5 km long from Oslo to Ski, the Geological Survey of Norway (NGU) on request from the Norwegian Rail Road Authority (Jernbaneverket Utbyggingsdivisjonen) conducted an upgrade of the geological and geophysical background material at a regional scale and delivered it in a digital form in 2007 (Lutro et al. 2007).
28 samples of groundwater from bedrock boreholes in three distinct Norwegian geological provinces have been taken and analysed for content of 222Rn, U and Th, together with a wide variety of minor and major species. Results are documented in NGU reports 93.121 and 93.126. This resport documents the locations and further details of the sampling points.
During June, 1997, a helicopter geophysical survey was carried out over Krokskogen, an area immediately northwest from Oslo. The purpose of the survey was to provide geophysical information to be used with geological datao to help determine the best route for tunneling from Sandvika to Hønefoss. Approximately 900 line-kilometers of radiometric, magnetometric and electromagnetic data were acquired, coverinbg an area of approximately 180 sq km. The average flying height was 80 m.
In August, 1998 and July, 2000, helicopter geophysical surveys were carried out over an area of about 560 km2 immediately west of Hurdalssjøen and the Garder- moen airport. The purpose of the surveys was to provide geophysical informa- tion for improved geological mapping. The data were collected by The Geological Survey of Norway (NGU) personnel and processed at NGU. A combined total of 2780 line-km of VLF, radiometric, and magnetic data were acquired using a nominal 200-m line spacing.
Rapporten gir en generell informasjon om naturlig radioaktiv stråling og hvordan denne måles. Videre gir rapporten en forenklet informasjon om radon i bomiljø. Det praktiske opplegget for NGUs målinger av naturlig gammastråling langs vei er beskrevet. Tolkningskart over naturlig stråling innenfor kommunen bygger på disse målingene og på berggrunnsgeologiske tolkningskart. Innenfor deler av Gjerdrum kommune er det påvist noe forhøyet stråling.

Thermal response tests (TRT) are widely used to measure the effective thermal conductivity and borehole resistance in a well. The gained data serve as the basis for the dimensioning of larger ground-source heat-pump installations with closed loop systems. The influence of groundwater flow on a TRT in fractured aquifers is not well understood. An attempt to quantify the influence of groundwater was done by pumping of groundwater from a nearby well during the TRT.
During June, 1997, a helicopter geophysical survey was carried out over part of Nordmarka, an area immediately northwest from Oslo. The purpose of the survey was to provide geophysical information to improve geological mapping in the area. Approximately 3260 line-kilometers of VLF, radiometric, magnetometric, and electromagnetic data were acquired, covering an area of approximately 650 sq km, mostly over the area covered by NGUs Oppkuven mapsheet.
The degree of saturation of groundwater with respect to a wide range of solid phases is calculated for 240 private and public bedrock wells in Akershus and Østfold counties, southeastern Norway. The samples were collected by the local Næringsmiddeltilsynene (Public Hygiene Control Office) in cooperation with the Geological Survey of Norway (NGU).

Chemical analyses of main, minor and trace elements have been made of Ordovician black (alum-) shale samples collected at two different localities and one waste pile in the greater Oslo area. The study is aimed at identification of differences between black shales from different localities by using main and trace element concentrations in whole rock for "fingerprinting".

Timely identification of subsidence is important in order to ensure that remediation efforts are successful. Even if subsidence cannot be prevented or stopped, it must be accounted for in new construction planning. Identification and monitoring of ground deformation can be accomplished using a number of surveying techniques. Levelling and GPS are both expensive and the number of benchmarks that can be controlled is limited.
