Probably a leaking heater core.
your heater core is leaking i would replace it.
Sportage has a drain plug on the bottom of the pan. which will drain most of the fluid out.
Either the heater core is leaking or you have a leak at the windshield or the cowl. If the fluid tastes sweet it is coolant and your heater core is leaking.
Have you used your air conditioning lately? The most common reason for water to appear to be leaking on the passenger floorboard is that the condensation drain for the air conditioning is plugged. Unfortunately, the drain is pretty much inaccessible to the average person and I have yet to discover a reasonable method of clearing it other than paying the dealer or a mechanic to do it. The other, less common causes for that type of leak is that the heater core is leaking, in which case the fluid will be antifreeze rather than water, or the door seal on the passenger door may be leaking, or the windshield gasket may be leaking.
The most likely culprit is the heater core.. its usually located under the dash on the passenger side.. if it starts leaking you will have water on the passenger side floorboard.. also the radiator fluid will be low.. Another possibility is the drain from the ac is clogged... alowing condenced water from the ac process to dump in the passenger side floorboard.. the heater core and the ac drain are located in the same area...
Heater core leaking or "bad"/ repair/replace. 4-8 hours labor + parts... pain in the rear (not the cars)

If you are driving and need to brake, but find your brake pedal is getting closer and closer to the floorboard, you need the check your fluid. Eventually your brakes will not have enough fluid to create the pressure needed to apply the brake pads properly and you risk accidents.
The water will boil when the fluid gets hot. Steam in the fluid will causes a loss of hydraulic pressure.
