Drinking water corrosivity, aggressiveness

The increased requirements of drinking water in large cities becomes necessary to use sources of very soft water and because of its low salinity and pH are very aggressive and can bring on corrosion phenomena in the pipes of the pipeline, with the appearance of colour and turbidity... 

If a proportion of the water from the old well is too high, the mixed water shows sulfate and nitrate concentrations exceeding drinking water standards (bold), if it is too low, the mixture is calcite aggressive (bold), which may lead to pipe corrosion. The optimum ratio is between 40 60 to 60 40, where the water can be discharged to the drinking water distribution net without any further treatment. 

Drinking water will wear away at more of the lead it is exposed to if the water has certain characteristics. Water is referred to as AGGRESSIVE or CORROSIVE if it tends to eat away at the... 

Since replacing plumbing in homes, or municipal water distribution pipes, is very expensive, it makes sense to control the problem of high concentrations of lead in drinking water by controlling the water s aggressiveness. This is referred to as corrosion control.
