black charred coloring on wires

[rick herweier]

Has anyone ever run across black like powdery substance on wires . This is in a residence, when I pulled out the plugs or switches the wires had a black substance on Very strange but other than the last time there was a wellsite blowout and some silverware went blackish there is no explanation .

It could be related to the drywall if this is a newer building. Take a look here:
