pH values on the gwh excel file

[Oscar Matias Benavente Zolezzi]

Hi Mike,

After solving the issue with the gwh.py file, I was able to run the pitlakq_tut_gwh project. However, few second later I got the following message:

  File "C:\Anaconda3\envs\pitlakq34\lib\site-packages\pitlakq\numericalmodels\existingmodels\w2\w2_proxy.py",
line 89, in get_shared_data    value = getattr(self.w2_fortran.shared_data, name)
AttributeError: 'fortran' object has no attribute 'phssgw'

Apparently, this error is related with the fact that is not possible to introduce a pH field in your gwh excel file. After taking this field out of the file I was able to run the project without any issue.

I'm not sure why is not possible to introduce a pH values to your gwh.xlsx, when it is possible to do it in the  groundwater_concentration.txt, mytribname_concentrationtxt or precipitation_concentration.txt

Could give some lights, please?

Cheers,
Oscar

Hi Oscar,

The pH is not a species that is transported. It is calculated from
the charge balance. So, if you would like to have certain pH, you need
to assemble an appropriate solution. Run PHREEQC and check that the pH
is correct. Typically, you need to adjust one specie such as chloride
or sulfate that you don't care about. In fact that is what PITLAKQ
is doing before the simulation with the initial lake water as well
as in the reprocessing step with the inflows. This explained in more
detail in the documentation [1].

Best,
Mike

Hi Mike,

Thank you for responding. I was almost sure about you answer, but my confusion arose from the fact that it is possible to add pH values in the other files.

Cheers,
Oscar
