Answers:    Green or blue water is usually cause by corrosion of copper plumbing. If corrosion is occurring,
dripping water will depart from a bluish-green stain on porcelain fixtures. Certain metals, such as copper, that
get into drinking marine from corrosion may pose a health concern. The problem could be within the home¡¯s
piping or corrosive water from the utility. If you suspect corrosion, contact your dampen utility or a
