We present an overview of the risks that underground thermal energy storage (UTES) can
impose on the groundwater system, drinking water production, and the subsurface …

Variable-head permeability tests are performed in monitoring wells (MWs) or open holes
between packers to assess the local value of hydraulic conductivity, K, of gravel, sand, and …

This paper deals with sandy aquifers. It explains how to use parameters of borehole
samples, and data of mechanical tests performed in boreholes, to assess the in situ values …

The PVC screens of recent monitoring wells (MWs) have thin slots and a low open area,
usually in the 2–8% range. The MW screen and filter pack may cause important head losses …

Methods for the estimation of groundwater level (GWL) are often based on knowledge-and
data-based approaches, which are largely affected by the representativeness of input …

Depth-dependent water-quality and borehole flow data were used to determine where and
how contamination enters public-supply wells (PSWs) at study sites in different principal …

The use of shallow geothermal energy (SGE) systems to acclimatize buildings has
increased exponentially in the Netherlands and worldwide. In certain areas, SGE systems …

1.1 Background Shallow geothermal energy (SGE) systems use the subsurface as a source
for thermal energy or as a medium to store seasonal heat. These systems provide heating …

The slug test is a common field technique for obtaining local hydraulic parameters near
wells, applied, for example, for the hydrogeological investigation at contaminated sites …

Deep saline aquifers can provide the capacity for disposal/storage of undesirable surface
fluids. To maintain containment and thereby prevent leakage of the injected fluids, the target …
