Ouch. I've seen some flooding in commercial and in houses. Commercial can be somewhat easier to deal with.
With that colour water and mix of fluids, I'd definitely be looking at pulling that carpet too, and maybe going with a plain floor, at least until you're sure things are clean and dry. Odd smells and mold would suck.
Nothing wrong with investigating a drip either! But how'd they manage to turn it into a flood?
