Mineralogical Evidence of Galvanic Corrosion in Drinking Water Lead Pipe Joints
The importance of galvanic corrosion as a mechanism of toxic lead release into drinking water has been under scientific debate in the U.S. for over 30 years. Visual and mineralogical analysis of 28 lead pipe joints, excavated after 60+ years by 8 U.S water utilities, provided the first direct view of galvanic …
