“…The thirteen (13) significant parameters selected for the determination of the WQI were EC, TDS, pH, TA, TH, Mn, Fe, Ca 2+ , Mg 2+ , Cl − , F − , NO 3− , and SO 4 2− . Equation (1) ([ 49 , 50 ];, 2020; [ [19] , [20] , [21] , [22] ]) was used to calculate the weighted arithmetic water quality index based on Ghana Standard Authority (GSA) water quality requirements for the different parameters. Where W i denotes the unit weight for every parameter, q i is the 0–100 subindex rating for each variable, and n is the number of consolidated subindices.…”
