Water Lab Analysis

The drinking water lab results provide an analysis of the output water from the Modit RO system, sourced from Perth (Darch) scheme tap water. The supply water exhibits a Total Dissolved Solids (TDS) of 420PPM, a pH of 7.2, alkalinity around 60PPM, and an Oxidation-Reduction Potential (ORP) of 665mV.

It's important to note that slight variations in the final water parameters may occur depending on the supply water's TDS and the maintenance of the system. However, barring extreme circumstances, the following parameters represent the typical range you can expect to encounter.


As per Envirolab's guidance, the ORP is measured onsite at the time the sample is taken, as its value can change over time. The submitted sample's ORP value was recorded at -307mV.
