Dr. Eugene, I have no words to thank you for this video! My name is Ana Carolina, and I am watching this video in September 2024. I am a Brazilian biologist pursuing a master's degree in environmental engineering. My thesis depends on this index to move forward. I couldn’t manage to do it on my own nor find anything on the internet that helped so clearly. Thank you so much, truly!
I feel so blessed and honored with you kind words. It means a world to me knowing that my small attibutio could make a difference. I appreciate your appreciation and I thank you so so much
Very nice explanation! I'm studying this Index and I wasn't trusting the F3 values I was getting... ... I find the distribution of F3 values very strange... For example: if I have all samples with twice the default... my F3 will be 50%... ... I think this greatly alleviates the problem of double overflowing the parameter.
Thank you very much (@Dr. Eugene ) for a clear explanation I have the following questions as per BIS 10500:2012, for turbidity, the acceptable limit is 1, and the permissible is 5. Why did you select 1 it will make a lot of difference you're using an acceptable limit for chlorides, i.e 250. plz clarify this Sir what to take BOD =5 in BIS not available thank you
Thank you very much for your efforts. I have a question about the number and type of parameters that can be used to calculate this index. Here, you have used 10 parameters.
Many thanks for the great video, could you please tell us about the protocols to measure all the mentioned parameters and the limits values with references? Thanks in advance
Hi @benchohra Maamar. The standard protocol for analyzing water quality parameters is the American Public Health Association, 2005 (The Bible of water quality analysis). Thank you
Thanku for the video.. an excellent presentation. I still have a doubt regarding the standard of water quality parameters. while calculating the indices, we must consider values of acceptable and permissible limits of water quality standards?
Appreciate it very much. It means a lot your kind words. Thanks a lot for that. For the values, first consider AV and if no AV, consider the HV. Ok thabk you all the best.
Sir, sorry for pointing this out, can explain why you didn't calculate the excursion=objective/failed test value -1 (for the cases in which the test value must not fall below the objective.)? is it not necessery or you skipped it?
Step 3.1 only one of the two is to be adopted and the readings obtained fits the first of 3.1. And if you try with the second formula you will get you data in negative.Thank you
Determining the WQI for that particular paramter (having permissible limit of zero) will be futile. it better to not incorporate parameters having 0 standard limits. I hope this will help you. Thank you 😊 for supporting 🙏
Could you Please explain, how use this method in case of irrigation because SAR, Pi, SSP, RSC and MR are calculated in meq/l and the heavy element are expressed in mg/l? I don't know how to deal with different unit?

Hello Sir If we have the data of same month of two different years then what will be the no of test? If no of parameters are 12 Then it will be multiplied by two or not?
Hi Siraj If for 2 Seasons and in each season you have 12 parameters analyzed Then the mean values fitted into the calculations is 12 ×2 = 24 Therefore no of test will be 24 Thank you 😊
can be used this method for one sampling time for each points? it means only wet season I have collected 40 water samples and I wished to analyze the using CCME WQI method. is it possible??
Hi Dilan. CCME WQI is best for >1 season of sampling. With one time sampling, no. of fail variables will be inconsistent. So the answer is no. Thank you Dilan Sir
Is it possible to use data between years instead of seasons? If possible, can data between seasons and years be used together to calculate the water quality index?
@Azzeddine Sir, to my understanding of our query, In a year you will analyze the water samples for different seasons. So technically your seasonal data made up your yearly data. Thank you
Hi @ Anti-Fool. There are four seasons in a year. Accordingly, you can divide the months and classify your data (if your sample collection is of course) seasonal in nature. Thank you.

Can I use this index to study and evaluate irrigation water?
If possible then where can I find quality categories -table- (good / poor-Excellent...)

Thank you so much... excellent
You're most welcome and I appreciate it very much Thank you 😊 🙏
many thanks for you , could you please explain the negative value of CCME .WQI ?
Hi Eissa
The index value ranged from 0 to 100.
So technically there is no way to obtain a negative WQI value thank you 😊
Thanks 👍👍
Sir, sorry for pointing this out, can explain why you didn't calculate the excursion=objective/failed test value -1 (for the cases in which the test value must not fall below the objective.)? is it not necessery or you skipped it?
Please respond !!
Step 3.1 only one of the two is to be adopted and the readings obtained fits the first of 3.1.
And if you try with the second formula you will get you data in negative.Thank you
When calculating the C= Excursion value, what should I do if a standard value is 0 (B value=0 for A/B)?
Determining the WQI for that particular paramter (having permissible limit of zero) will be futile. it better to not incorporate parameters having 0 standard limits. I hope this will help you. Thank you 😊 for supporting 🙏
Sir,
Here you said 12 parameters * 2 seasons.
But my data is bimontly in a year then what shold i do
11 parameters* 12 month
My data are just an examples. You can input your data according to the no. Of season or sites or year studied. All the best and thank you 😊
Hello doctor, can you send me this excel file that you are working with?
thank you for the video. its great.
Thank You so much @Oliver. Your appreciation inspire me to perform better day by day. thank a lot
Sir, if I have collected data two time in a year with 10 parameters then no. of test will be 10*12 or 10*2?
Hello and it will be 20. 10 parameters *2 seasons. Ok. Thank you 😊
Excellent presentation.
Thank You so Much Sir, Appreciate It
Could you Please explain, how use this method in case of irrigation because SAR, Pi, SSP, RSC and MR are calculated in meq/l and the heavy element are expressed in mg/l? I don't know how to deal with different unit?
Sir if I have monthly data with 12 parameters then no. of test will be 12*12 like for 3 seasons it is 12*3
Hi, 12 *12 is correct. But 12 *3 is not.
It will be 12 *12 only in your case ok. Thank you 😊
Excellent work
Thank you so very much @GiS. It means a lot to me
Excellent Job

@@JustLikeASteam not season Sir
Two data sets of same month (January) of 2019 and 2020.

@@ghazalasiraj8861 it's not a good set of data for Using WQI. Because data are from different months and year .Thank you

You can avail these from any prescribed standard you selected for your study
BIS or WHO or EPA etc
Thank you 😊
