Frequently Asked Questions about COPPER in Water
A5. Since natural levels of copper in New York State water supplies are low, copper in drinking water usually results from the use of pipe and fitting materials in water systems. Water in the plumbing system can dissolve copper from pipes and solder. This is called leaching. Soft, corrosive or acidic (low pH) water is more likely to cause leaching.
