Muhammad Rumi Azhari Nur Irfani

Hello,

I just calculated the WQI number through pH, temperature, and TDS/TSS parameters in Microsoft Excel some days ago.

Would you like to try my formula in Excel file? I can send you through your email.

The Excel file is courtesy to my study in Water Quality Assessment from my University.

Thank you,

regards.

Sal Mangiafico

Which WQI are you using ? Do you have a link to it ?

Swagata Chakraborty

Muhammad Rumi Azhari Nur Irfani, Thanks for your reply, I would like to try your formula.

Please connect me at chakraborty[dot][email protected]

Thanks,

Sal Mangiafico, sir, I need the formula for the analysis.

Muhammad Rumi Azhari Nur Irfani , would you be able to share, briefly, the formula you used, how the WQI was developed (if developed by you), or a source for the WQI you used (if it's a published index) ?

Sal Mangiafico I am sorry if I can't say much about it, since it was developed by someone else from my university, as it was only given to me to assess the local river quality index. Also, the context of my WQI formula is for classification according to Malaysian WQI Standard, but it should be enough to give you a picture of how the calculation is formulated.

I will send the file to you personally through a private message. Thanks.

Thanks for the file Muhammad Rumi Azhari Nur Irfani . As mentioned there, the index is specific for the water quality standards of Malaysia, for rivers, and for the specific water quality parameters measured. ... This is one of the difficulties in using WQI. That they are usually developed for specific regions and purposes, and require the input of experts to make a meaningful index.

Muhammad Rumi Azhari Nur Irfani, thanks for your information.

Chaitali Thali

Please share the WQI excel on [email protected].

Musaab A. A. Mohammed

It's possible to calculate different WQIs. For instance, Weighted arithmetic WQI can be measured by applying unequal weights and then calculating each parameter's relative weight. Please follow the reference provided and it hopefully will be clear.

Thank you so much, Musaab A. A. Mohammed

For water quality index ,need to be total chemical analysis. for example Na,K, Ca, Mg, Fe. Chloride, sulfate, bicaronate and others.
