What are the major causes of corrosive water?

The major causes of corrosive water primarily relate to its ability to corrode materials it comes into contact with, and this is effectively represented by the correct option. Dissolved oxygen content plays a crucial role in the corrosion process, particularly in the form of oxidative corrosion where oxygen interacts with metal surfaces leading to deterioration. Electrical conductivity is also a significant factor, as it indicates the presence of ions in the water which can facilitate the movement of electrons and thus enhance corrosion reactions. The aggressiveness of water refers to its capacity to cause corrosion, which can be influenced by various chemical properties and environmental factors, making this combination particularly relevant to corrosive water.

Understanding these factors is essential for managing water quality, especially in terms of infrastructure and plumbing systems, where corrosion can lead to significant damage and health risks.
