The analysis of indirect inspection data is a critical factor in conducting a successful ECDA process. Any “out of range” data must be validated prior to being considered an ECDA indication. Furthermore standard methods of validating the accuracy of the field data must be reviewed under special conditions.This paper covers a number of lessons learned by dealing with less-known sources of measurement error during nine years of ECDA application on more than 100 projects.Topics like “clipped” gradients during the DC Voltage Gradient Survey AC current drain by well casings during influence testing and sharp drops in potential suggesting the presence of an underground isolating flange are discussed in detail in this paper. Keywords:  ECDA CIPS DCVG AC interference DC interference isolating flange.
