| 1 | HCO3 and Ca dominant; indicates recharging waters groundwater | 14 | 66.67 | 10 | 55.56 | 4 | 22.22 | 9 | 50 |
| 2 | This water type is dominated by Ca and HCO3 ions. Na is significant, ion exchange is presumed | 3 | 16.67 | 4 | 22.22 | 2 | 11.11 | 0 | 0 |
| 3 | HCO3 and Na are dominant, normally indicates ion exchanged water, although the generation of CO2 at depth can produce HCO3 where Na is dominant under certain circumstances | 0 | 0 | 0 | 0 | 1 | 5.56 | 0 | 0 |
| 4 | SO4 dominates, or anion discriminate and Ca dominant; mixed water or water exhibiting simple dissolution may be indicated. | 0 | 0 | 2 | 11.11 | 10 | 55.56 | 5 | 27.78 |
| 5 | No dominant anion or cation, indicates water exhibiting simple dissolution or mixing | 0 | 0 | 0 | 0 | 1 | 5.56 | 3 | 16.67 |
