Choose microbiological and physicochemical parameters according to whether the water is for drinking, processing, RO, ice, discharge or another purpose.

The exact parameter list should be matched to the intended use and applicable standard.
| Physicochemical | pH, TDS, hardness, conductivity and other product/use-specific parameters. |
|---|---|
| Microbiological | Total coliforms, E. coli and other indicators/pathogens where applicable. |
| Environmental | Wastewater parameters selected for the discharge/compliance requirement. |
