Abstract
The passive flux meter (PFM) enables the measurement of cumulative water and
contaminant mass fluxes in porous aquifers. It consists of a sorbent material,
which is installed in a monitoring well to intercept groundwater flow. Tracer
losses and contaminant retention on the sorbent are used to estimate water and
contaminant mass fluxes through the device. In the multi-layer PFM different
(sorbent) materials are used in an annulus (layer-type) configuration. This allows
leached tracers inside the PFM (no tracer release into aquifer) to be retained and
facilitates simultaneous deployment of different sorbent types in a single device.
In order to estimate undisturbed ambient fluxes in the aquifer, measurements
need to be corrected for flow convergence or divergence induced by the well and
PFM components. We make use of an analytical solution to the potential flow
