Reaction time between groundwater and minerals

(1/1)

Matsumoto:
Hello everyone.
I am a university student in Japan and I am studying the mechanism of water quality formation in a particular spring.

I would like to know how long it takes for the minerals present in the study area to dissolve and form the known water quality.
Is it possible to measure the residence time, etc. with PHREEQC?

Thank you for your reply.

dlparkhurst:
I think it is unlikely you can estimate residence time from the chemical composition alone. Usually, tracers like tritium, CFCs, SF6, or carbon-14 are used to estimate residence time for ground-water.

Matsumoto:
Thank you for your response!
I see that residence time cannot be measured using PHREEQC.
