CSI compliance and site inspector.

I have come across a well pump water supplied home and found green deposits over much of the copper piping and on supply line feeds to faucets. Where can I find some site information explaining this problem

Would need more information about the problem to offer advice. Start with some good, clear, close-in photos of the copper piping, and detailed information about the home, such as location, age, typical water chemical composition for wells in the area, etc…
