Reduction of lead and copper in potable water systems has been mandated by the USEPA. One component of this program is the use of chemical treatment to reduce corrosion of piping and solder to prevent entry of these metals into solution. Field application of electrochemical noise corrosion monitoring in these systems is demonstrated in side stream test loops. The quality of the electrical isolation of the measuring instrument is critical to obtaining usable information.
