Why should water be non-corrosive according to state recommendations?

Water should be non-corrosive according to state recommendations primarily to ensure safety in plumbing systems. Corrosive water can react with metal pipes and solder, leading to the leaching of harmful metals such as lead and copper into the drinking water supply. This not only poses health risks to consumers but can also cause structural damage to plumbing infrastructure over time. By ensuring that water is non-corrosive, utilities can help maintain safe drinking water standards and protect public health.

The other factors, while they may have certain effects on water quality, do not reflect the primary safety concerns that drive the recommendation for non-corrosive water. Taste issues, mineral content, and filtration requirements are secondary considerations when compared to the urgency of preventing contamination and maintaining the integrity of plumbing systems. Therefore, emphasizing non-corrosiveness is critical in the context of health and safety regulations.
