During a radio interview I gave, the question was asked if I thought water had any bearing on paranormal activity. At the time, I hadn't given the idea much thought. But if you consider that paranormal activity seems to be electrical in nature (draining batteries, pulling from heat energy, more prevalent during solar weather and causing changes to EMF) and water can be a good conductor of electricity, then it stands to reason that water could help fuel a haunt.
First, we need to clear up the science of water's ability to conduct electricity. Water itsself does not conduct electricity. It's the impurities in the water (minerals, pollutants, etc.) that conduct electricity. So the more impurities you have the more conduciveness you have. The Discovery Channel's "Ghost Lab" show featured the theory of water fueling the paranormal on their "Murky Waters" episode. It was found that the waters of the Mississippi River near the Nottoway Plantation had a high level of conduciveness. But what about other paranormal "hot spots"?
So the next time you're out investigating, think about checking to see what bodies of water might be in the area.
