PSI means..,Pollutant Standard IndexProvide;
◦Accurate & easily undesirable information about air quality
six pollutant parameters◦sulphur dioxide (SO2), ◦particulate matter (PM10) ◦fine particulate matter (PM2.5)◦nitrogen dioxide (NO2), ◦carbon monoxide (CO) ◦ozone (O3)

Water Quality Index (WQI) The WQI is based on the results
chemical tests:1. Dissolved Oxygen (DO)2. Fecal Coliform (FC)3. pH4. Biochemical Oxygen Demand (BOD)5. Turbidity6. Total Dissolved Solids (TDS), etc.
These tests were chosen because they significantly impact aquatic organisms

Water Quality Index’s (WQI) Formula

SIi =the subindex of ith parameterqi = the rating based on concentration of ith parameter n = the number of parameters
