More than likely it is your door seals and the water is taking the path of least resistance, you should also check the windshield area for leaks.
It should connect at the back of the sunroof under the headliner and I think the hose drains out of the trunk near the rear wheel well.
You have the infamous "Wet Carpet Syndrome". Check your cowl for leaks.
There is a drain tube that goes through the firewall and comes out under the car. Use a piece of wire to stick up there and unclog it, water will run out when you have got it.
Consider mold growing in the jute (soft padding under the carpet) after exposure to water. Also check for water leaks at windows (including windshield) around doors or in the trunk.

The most prosaic explanation is that something spilled there and the water soaked through the carpet.
