Method of Locating Buried Lead Water Pipes using Infrared Analysis

摘要

A method of locating lead goose neck pipes connected between a water main and a water service line buried under a surface comprising, using infrared (IR) photography to scan the surface above the buried pipes; wherein the water main and water service lines are constructed of a metal having a higher thermal conductivity than lead; and determining the presence of lead by differences in surface temperatures of the lead pipe and the water main and/or the service line as indicated by the infrared photography.
