‘open-loop’ system uses groundwater orlake waterdirectly as a heat source in aheat exchangerand then discharges it into another well, a stream, or lake, or even on the ground. The installation of horizontal coils requires relatively large surface area and extensive earthworks (digging the ...
This well was located near an unsewered commercial area; wastewater from local businesses that use PFASs in paints, textiles coatings, or floor waxes may have been a source of PFASs to this well. The results from our wells show the complex interactions among multiple sources of OWCs and ...
Tubewell ID-17 became too tight to pump water (due to an increase in the height of the barrel of the handpump) after the installation of Zimba. We received complaints from household users that they were unable to pump water. Only three water samples in household storage containers had ...
The interception of aquifers during borehole heat exchangers installation may cause the contact of swelling or soluble layers with groundwater and trigger consequent hazardous phenomena. The transformation of anhydrite into gypsum is one of the well-known swelling phenomenon, characterized by an increase...
Uncertainties in the analysis method are attributable to the inherent limitations of matheEmneargtiiesc2a0l17m, 1o0,d20e4l4s used to determine ground conductivity and borehole resistance16 vofa5l3ues as well as the duration of thermal response tests. In References [100,120,128], detailed ...
