and pH Tests

Conductivity is an indirect measurement of total dissolved solids.

The typical value (approximately) for untreated distillates is 50 μS/cm. Water from shore sources should have around 500 μS/cm. Seawater has about 50,000 μS/cm.

Therefore, a high conductivity could indicate seawater ingress. A too low conductivity value should trigger an evaluation of corrosive processes in the piping and the presence of heavy metals due to corrosion

The pH value of water is a measure of how acidic or basic it is, and it depends on the types of substances that are dissolved or suspended in it.

The pH value affects the effectiveness of chlorine as a disinfectant, as well as the mineral content and the corrosion potential of water.

If the pH value is higher than 8, or 10^(-8) mol/L in hydrogen ion concentration, chlorine cannot kill bacteria and viruses in the water properly.

A high pH value also indicates that the water may lack essential minerals, such as calcium and magnesium if it is produced by distillation or reverse osmosis.

These minerals help to balance the pH and prevent the corrosion of pipes and metals.

Check the water quality further by using other tests, such as conductivity, hardness, alkalinity, and turbidity.
