I just went over the water quality report of my water supplier and checked the numbers.
It's tested at our local pumping station.
The conductivity is 23,8 mS/m wich i calculated is about 152 TDS.
In the list of dissolved stuff is says Waterstofcarbonaat 107 ppm (which is carbonic acid).
What i can find about this acid is that it gets picked up when you measure conductivity.
What i understand about this is according to these numbers, 107 out of 152 of my waters TDS is harmless co2, which leaves me with 45 TDS.
Am i right about that ?
