How does lead get into the drinking water?
Not all drinking water contains lead. When household plumbing contains lead solder, and the water is in contact with the solder for long periods like overnight), their may be some lead that does dissolve and enter the water. This is also a function of the corrosivity of the water. Very hard water tends to from a scale on the walls of the pipes, and seals the solder. Lead solder has been outlawed since 1986. Testing in Amador Water Systems has not detected any lead or copper in the system above action levels set by EPA.
