CHEMISTRY OF GROUNDWATER IGNEOUS ROCK
<
2009/10/29
Within an area of about 5 km2, 25 wells were drilled to depths of about
90 m for groundwater observation. The wells were sampled and analyzed,
and from the results it could be concluded that the ion...

The content of 222Rn in drinking water from 118 wells in southeastern
Sweden has been measured. The radiation dose from 222Rn is completely
dominant in comparison with the dose from other nuclides e...
Chemical changes in water circulating deep in the fissures of the solid
rock are studied. The ultimate chemical composition is determined by
the conditions of percolation through the soil zone. For ...
Experiments have been made in the field to determine the way in which
fuel oil No. 1 spreads in some common unconsolidated deposits in Sweden,
such as esker material, bottom varves of glacial clay a...

During the last decades several wells giving yields up to 100,000 llh have
been drilled in the reddish Brumunddal Sandstone, which covers an area
of approximately 10 km2 near lake Mjosa, Southern No...
Movement and leaching of residual nitrogen in soil has been studied in some
details in a lysimeter experiment. Profile measurements of soil water and of
nitrogen concentration in addition to measure...
