MIN3P Verification Examples: Ion exchange (comparison of MIN3P
simulated data to observed data)
This example, described in detail by
Valocchi et al. (1981) compared field observations from the Palo Alto Baylands
groundwater recharge site to simulated data.
At the Palo Alto site, an advanced wastewater treatment facility and an
injection/extraction well field has been studied to determine whether direct
injection of municipal effluents is a reliable and feasible strategy for
producing potable water. Inorganic and
chemical changes due to ion exchange processes have been observed at the site,
and a mathematical simulation model of the transport of ion-exchanging solutes
was developed and tested to understand and predict these chemical changes
(Valocchi et al., 1981).
Figure 1 shows the field observations
of the breakthrough of Ca2+ and Mg2+ at the Palo Alto
site with MIN3P simulated data.
