Safe disposal of high-level radioactive nuclear waste (HLW) is crucial for human health and
the environment, as well as for sustainable development. Deep geological disposal in …

During the past few years, the number of regional and national assessments of groundwater
quality in regard to saltwater intrusion in coastal aquifers has increased steadily. However …

Fluvial sedimentary successions represent porous media that host groundwater and
geothermal resources. Additionally, they overlie crystalline rocks hosting nuclear waste …

We report compositional, microstructural and seismic properties from 24 samples collected
from the Middle Allochthon (Seve Nappe) of the central Scandinavian Caledonides, and its …

Contamination of the Paleozoic carbonate aquifer at Walkerton (Ontario, Canada) by
pathogenic bacteria following heavy rain in May 2000 resulted in 2,300 illnesses and seven …

The deep biosphere hosted in fractured rocks within the upper continental crust is one of the
least understood and studied ecological realms on Earth. Scarce knowledge of ancient life …

To characterize the coupled hydromechanical behavior of rock fractures, the step‐rate
injection method for fracture in‐situ properties (SIMFIP) was conducted with a specialized …

Flowing fluid electrical conductivity (FFEC) logging is a hydrogeologic testing method that is
usually conducted in an existing borehole. However, for the 2,500-m deep COSC-1 …

Single borehole dilution tests (SBDTs) are an inexpensive but effective technique for
hydrogeological characterization of hard‐rock aquifers. We present a freely available, easy …
