DATA MANAGEMENT FOR UNDERGROUND LEAD PIPE DETECTION

Abstract: a probe provides one end of an electrically conductive path with a ground stake defining a second end. the probe is supported on a tip of a cable rotatably supported by a snake, with the snake including a conductor routed toward the ground stake. a spool can optionally be located between the conductor and the ground stake. a voltage source and a current sensor are located upon this electrically conductive path. the current sensor senses current flow between the probe within the underground pipe and the ground stake. analysis of the current flowing in this electric circuit allows for determining if underground pipe material includes lead, based at least partially on electrical conductivity of pipe segments through which the probe passes. conductivity data is transmitted between a local processor, such as a smart phone, and a remote processor for analysis, including a prediction as to lead presence in the pipe.
