In relation to electrical conductivity, what happens when total dissolved solids content is high?

When the total dissolved solids (TDS) content in water is high, the electrical conductivity of the water also increases. This is because electrical conductivity is directly related to the concentration of ions in the water, which are primarily derived from dissolved solids. Higher ion concentrations enhance the water's ability to conduct electricity, thereby increasing its conductivity.

With increased conductivity, the potential for corrosion also rises. This is due to several factors: water that is highly conductive can more easily carry electrical currents, which can lead to electrochemical reactions that cause materials, such as metal pipes or fixtures, to corrode over time. Additionally, the presence of various ions, such as chlorides and sulfates, often associated with high TDS, can exacerbate the corrosive effects on metals.

In summary, the correlation between high total dissolved solids content and increased corrosion risks is well-established, as the presence of more conductive ions facilitates and accelerates the corrosion process in various materials water typically comes into contact with.
