What is a sign that water may be corrosive to lead pipes?

Soft and acidic water is a significant indicator that water may be corrosive to lead pipes. This type of water has low mineral content and a low pH, which can lead to an increased ability to dissolve certain materials, including metals like lead. When water is soft and acidic, it is often less buffered against changes in pH, allowing it to corrode pipes more readily. This corrosion can release lead particles into the drinking water, posing health risks.

Understanding the characteristics of corrosive water is essential for lead risk assessors, as it directly relates to the safety and quality of drinking water systems that may involve lead piping. Identifying signs of corrosive water in relation to lead is crucial for effective assessment and intervention strategies in environments where lead exposure could occur.
