Okay, so this is where I stand. Finally finished cleaning the railing cups in the shallow end. Now, everything is clean with good tight connections on the visible part. I even cleaned the copper at the equipment pad as well as the split bolts and put them back together (SWCG and pump are now both connected to the copper wire coming out of the ground at the equipment pad). Still reading between 0.2 and 0.4 volts when pool deck concrete is wet and put one meter end in the water and touch the other end to the wet concrete. The rebar that was put in to secure the new concrete to the old concrete is no less than 39" from the pool wall. However, that rebar was NOT connected to the bonding grid when it was installed. There is still a ground rod driven into the earth next to my equipment pad that I have not been able to remove, yet.
Three questions.
1) Could the grounding rod that was "installed" by the electrician who came out be causing any issues?
2) Could the connections of the pump and SWCG to the bonding grid within 6" of each other cause any issues?
3) Could having a high PPM of salt cause any issues?
My suspicion is that I will need to cut a channel about an inch wide in the new concrete, connect the new rebar to a new #8 bare copper wire, connect that new copper wire to the existing copper wire at the equipment pad, and bury it 4"-6" below grade. Would this be an accurate assessment given the voltage reading we are still getting? What would be the long term implications of this should people swim? Would the bonding grid not fully work because of the rebar in the new concrete and thus potentially allow high voltages to enter the "area" causing possibly hazardous shocking potential?
