The proposed model has higher 
for any one of scales of L1, L2 and L3 for most of the pollutant factors as seen in Table 4.
Table 4
Correlation of THE proposed health risk score to pollutant factors
| Pollutant factor |  | Fitness |
|---|---|---|
| SO2 | L2 = 0.89 |  |
| NO2 | L1 = 0.84 |  |
| Total dissolved salt (TDS) | L2 = 0.98 |  |
| Fluoride (F) | L2 = 0.81 |  |
| Total hardness (T.H.) | L1 = 0.86 |  |
| Iron | L1 = 0.88 |  |
