ground cable close to gas line?

Ground wire attached by water meter and runs back to the panel next to, and in contact with a 1" gas main that runs thru my basement.

Is there any concern having the ground this close to gas?

Actually, I believe not.

This seems to be very common on water heaters. They use the copper water line as a ground to complete the circuit if not a conduit available. It's a safety ground line in case of surge or lightning strike.

This ground cable (a grounding electrode conductor) touching your gas line is not a problem.

In fact, your gas plumbing system needs to be grounded also. One method is running a similar ground cable (typically a #6 copper bare wire) from the gas pipe to the same place (neutral bus bar) in the panel. Should this new cable first reach an existing GEC, here, less then a foot* away, it may be clamped on there rather than continue all the way to the panel. The gas pipe exiting the house does not count as a grounding electrode. The cable you attach to the gas pipe, although installed in the same manner as that running to the water pipe is called a bonding jumper rather than a GEC.

If you have a gas appliance (such as a furnace) that uses electricity and has up to date wiring to a branch circuit with ground, then no bonding jumper is needed.

*Wires and cables should be attached to the wall rather than float freely among or away from other objects.
