Tingle / Shock from inground pool

Posted by on May 9, 2007, 10:50 pm

I have an inground pool with concrete decking. If you have a cut or
scrape on your body you can feel a mild shock or tingling sensation
while touching the decking or aluminum coping. For example, if you
have a cut on your hand and put this hand in the pool water, then
place your other hand on the concrete decking, you feel a mild shock.
This cannot be felt unless the skin is broken. A woman who has
recently shaved her legs will also feel the tingling. The is about .
8v of current detected with a meter from the pool water to the
concrete deck. Do you think this is some type of ground issue, etc?
I can provide many more details to anyone who has suggestions or think
they know what the problem is.

AC current. It ranges from .600 to .900 at different times.

do your service wires to the house run underground? if you shut off
your mains to the house do you still get the tingle? if yes you might
need to contact your power company. i had a similar service call, i
was getting 4 volts ac i know they drove some ground rods (several) to
try and bleed off the stray current. dont know what came of it but i
havent been sent back.

Yes, service wires are underground. I have shut off the the mains and
the shock/tingle still exists. One problem is that I do not know how
the pool itself was grounded. Also, the person who did the concrete
did not ground the rebar (I think). Any thoughts on how to do this
after the fact, or any other tests I can do? I called the power
company and they are supposed to come out within a week. The other
odd thing is that stray voltage isn't supposed to be a problem unless
its 4+ volts. My voltage is less than 1 and I can still feel it, but
only if you have an area of broken skin that contacts the water. All
around my house I get a 1 volt reading by putting a meter probe in the
ground and the other on a bare metal piece of a downspout.
