I think Undine's Spring would still be polluted after three years. Undine said it would take years for the spring to cleansed and goes there every day to help purify it, although she didn't specify or estimate how long and she's not trying to rush it. The spring's inhabitants are taking refuge at Plansect.

Then again, freaking Promestein and her technology could probably speed it up.
