What are the criteria for identifying the value of the parameters' weight in Weighted Arithmetic Water Quality Index (WA-WQI) ?

07 June 2023 0 2K Report

For Weighted Arithmetic Water Quality Index:

Is there a reference to select a value from 1 to 5 for the weight of water quality parameters?

I want to give weight (wi) to the chosen water parameters (LIKE: EC, TDS, Fe, Na, Tur., ……and so on) according to their relative importance in the overall quality of water for drinking purposes. So I wonder if there is a specific table for this.
