1. It's otherwise unuseable, and you're not diminishing a valuable resource
2. The pollutants could help the process by ionizing the water
3. The process leaves behind the pollutants in a purer concentrated state to be dealt with

I've realized that this likely will not work. If the solution is ionized in order to conduct electricity well the conducted electrons will not be available for work (dissolution of water) resulting in Faradic ineffeciency.

Worse still, it is possible the current or thermal energy from Joule heating might drive chemical reactions producing unfavorable products.
