Pure water = 18.2 M-Ohm-cm.

"De-ionized" water has the highest resistivity you can get in water. When water is exposed to air it absorbs carbon dioxide and becomes acidic and its resistivity drops, so it must be continuously filtered to remain pure. It also drops due to dissolved minerals, lead, etc.

By contrast, superconductors have exactly zero resistance.

Cheers,
Scott.
