Even though it's not saltwater, I'd get your lenses to a service shop ASAP. That water looks like a good candidate for disolved and/or suspended organic matter, which can not only lay a murky film on glass when it dries but lead to eventual mold or decomp products.
I've dunked far too many lenses in my career, and anything short of distilled water is likely to affect internal optics even if you manage to get the lenses completely dry, which I doubt you can manage without help.
Now on to the topic of your NEXT insurance policy.....
Sorry for your mishap, but as you said, better to lose the stuff than a loved one.
