In case you were wondering, clean pure water does not conduct electricity.
While Griswalds' statement is correct, your pool water, no matter how clean and pure you think it may be, should never be mistaken for distilled water, or considered non conductive.
Lets be perfectly clear here. Tap water, your
pool water, lets say for arguments sake all water is or should be considered conductive,
unless....

Since
distilled water is purified and does not contain any impurities, it is unable to conduct electricity. Water molecules on their own have no charge and as a result they cannot swap electrons. Without the swapping of electrons, electricity is unable to travel through distilled water.
Salt water, on the other hand, is considered a good conductor of electricity because it contains ions in it. Although it doesn't taste salty,
Tap water, can also conduct electricity because it isn't pure. The water from the kitchen sink often has traces of minerals such as calcium, Ca2+, and magnesium, Mg2+ and can help conduct electricity. However, what needs to be noted here is that not all water is the same nor will it conduct electricity at the same rate.
