Pure water is almost an insulator. Extremely small amounts of dissolved salts, gases or metal ions increase the conductivity tremendously. For instance try this. Take some DS and measure the conductivity. Then let it set in a glass for a few minutes and you will find that the conductance has increased several times over due to the dissolving of minute amounts of carbon dioxide. Dip your finger into a gallon of distilled water and you might find that the conductivity has increased significantly due to the traces of salt on your skin. If water is distilled using any metals, such as copper, for condensation, or in the piping, that will add copper ions and increase the conductivity.
