Abstrakt
The arsenic content in groundwater of the Red River floodplain decreases
with the burial age of the aquifer sediment over a 6000 year period.
This decrease is caused by diminishing reactivities of both sedimentary
organic carbon, Fe-oxides as well as CaCO3. Here we present a
1-D reactive transport model developed in PHREEQC-3 that quantifies the
resulting changes in groundwater bulk chemistry as well as arsenic
content over the last six millennia.
