Why Lead solder in plumbing can leach into drinking water, particularly from the first draw of cold water after periods of non-use Is Correct

Answer B: Lead solder in plumbing can leach into drinking water, particularly from the first draw of cold water after periods of non-use

Older plumbing systems may contain lead solder (used before 1986 when the Safe Drinking Water Act banned lead solder). It can leach lead into drinking water, especially during first draws after the water sits in pipes.
