water sitting in the back and front driver side floor

You'll need to determine if this leak is from outside the vehicle, as in with rain occurring or a car wash -- check for moon roof drains being clogged for one example of an easy place to check. There are many places leaks can originate from, though, so testing is required hands-on. Secondary: you could have evaporative water from your climate control system not draining properly, allowing it go get inside the vehicle also. Again, testing is needed.
