Hi

As water is slightly alkaline it may of now damaged the carpet.

But, you could try a low moisture like bonneting or EnviroDri, with just a pre spray.

Its wickback.  Was it a low profile carpet?  You need to go back and bonnet them.

Mike,

Might be worth hand drying the edge of the tide mark with a terry towel. You'll be amazed how much crap comes off even after you have extracted and bonneted and this should help it blend into the rest of the carpet. Definitely sounds like wick back to me.
