Free ions in mineral waters

["Tobias Oberstein" <Tobias.Oberstein@xxxxxx>]

Dear water experts,

I've successfully compiled your PHREEQC package from source
on a OpenBSD/Intel box (though the test suite reports
some diffs : http://www.brainthat.com/check.out).

I've looked at some examples, but honestly I'm a bit lost.

What I'd like to do (in a first step) is ..

-------------------------------------------------------
Compute free ions and complexes in mineral waters
of natural origin (that is ground waters, deployed
for human consumption).
-------------------------------------------------------

Further, I'd like to calculate the above stuff not
only for the measured pH of the water, but for an
pH of 7.5, as this might be a realistic value for
the mileu in small intestine, where water/minerals
are absorbed.

Could you please give me a hint on what example to
use as a template e.g. ?

I'm willing to make the results available as an
online service both via HTML-Forms and remote calling
via XML-RPC / SOAP (my programming know-how is much greater
than that in geochemistry ;)

Further, I've got data for 165 natural mineral waters
from germany.

Thanks a lot, Greets
