A 25 mm (1 in.) copper coupling had been uniformly degraded around most of the circumference of the bell and partially on the spigot end. One penetration finally occurred through the thinned area on the spigot end of the pipe. Investigation supported the conclusion that although the pipe was buried in noncorrosive sandy soil, it was found to incur stray currents at 2 Vdc in relation to a Cu/CuSO4 half cell. Recommendations included eliminating, moving, or shielding the source of stray current.
