Heater valve, rust holes?
Do a taste test to see if it is coolant.

the notorious rear arch rust?

Just noticed OP says rear!
There's two big round metal plugs in the rear floor pan; one each side.
These come loose or rust and let water in.
Depending on what state they are in, they can be refitted and sealed, or remove them completely and weld plates over the holes.
