Dipole tracer tests to examine flow and transport between wells

Dipole tracer tests to examine flow and transport between wells
In many older landfills in the UK, significant depths of saturated waste exist (and are permitted) in sites benefiting from natural containment created by surrounding geology with low permeability. In order to accelerate solute flushing in these sites, the introduction of water and removal of leachate between vertical wells is a practical option. The basic hydraulic unit for such systems is a simple well-pair, whereby one well injects fluid and a second abstracts at the same rate. Such a pair is often called a dipole or a doublet. It is useful to understand flow and solute movement in this basic unit, which can thereafter be used to design more elaborate field-scale systems.

In this study, the hydraulic and contaminant transport properties of dipoles were examined at varying scales in a landfill by running dipole tracer tests using Rhodamine WT dye.

Abstract

In many older landfills in the UK, significant depths of saturated waste exist (and are permitted) in sites benefiting from natural containment created by surrounding geology with low permeability. In order to accelerate solute flushing in these sites, the introduction of water and removal of leachate between vertical wells is a practical option. The basic hydraulic unit for such systems is a simple well-pair, whereby one well injects fluid and a second abstracts at the same rate. Such a pair is often called a dipole or a doublet. It is useful to understand flow and solute movement in this basic unit, which can thereafter be used to design more elaborate field-scale systems.

In this study, the hydraulic and contaminant transport properties of dipoles were examined at varying scales in a landfill by running dipole tracer tests using Rhodamine WT dye.
