Why is there water on passenger floor boards on 2000 Chevrolet Tracker

When I drive my car 30 miles or more the floorboard becomes soaked with water and I have no clue what to do for it. Any suggestions are appreciated

if you have ac i would check to see if the drain hose is plugged if not your heater core could be leaking
