pH
A core chemistry parameter influencing metal solubility.
What is pH?
pH describes how acidic or alkaline water is on a logarithmic scale.
Why test for it?
pH influences corrosion and how readily metals dissolve, so it supports the interpretation of metals results.
Where can it come from?
- Source water geology
- Treatment processes
- Contact with pipework materials
How is it measured?
Measured electrometrically as soon as practicable after sampling, as pH can drift on storage.
What does my result mean?
pH is best read as part of a chemistry set with alkalinity, hardness and conductivity.
