The operation of the Washington D.C. rapid rail transit system has produced stray current activities on limited portions of Washington Gas Light Co.'s underground gas system. As a result of selective maintenance activities, there has been a significant reduction in stray current at pickup and discharge areas along the pipeline system. This article explains how stray current mitigation can prevent the necessity for mitigation bonds and some of the undesirable side effects that could result from the further spread of stray currents to distant parts of a gas system.
