Possible heater core leak. That would make the water radiator fluid. if just clean water some look for the nearest hose.

got a sunroof in this? If so, clean the drain tubes.

Leaking water on teh drivers side indicates a cracked block or cracked head in most cases. Unless you have a water injected motor, I don't remember Ford using one, there are no water ports on that side of the motor. It could be the water pump leaking and being pushed back when the vehicle is running so check for leaks around the water pump. You need to check the heads, side of the engine block and the freeze plugs to make sure there are no cracks or leaks around the head gasket seal.

If the fluid is a bright green or yellow colour, it is coolant fluid. Check the water pump, there should be a seal leak drain hole under it, look for signs of a leak. If there is a green/yellow track leading from below the water pump. you need to have the water pump replaced. A leak from the engine would be dark brown to black an a transmission leak would be red tp very dark red. Coolant would tend to dry up while oils spills do not. The water pump is located on the side of the engine where the belts are. I do not know if your car is left or right hand drive.

Generally, water on the passenger side is the A/C drain tube.
Driver side generally means widshield or sun roof seal leak.
Did you wash the Mazda or did it rain prior to puddling?
Before disassembling the windshield seal, test ... with a water hose (Remove floormat and place a towel on newspapers on the driver's side floor).
There is a "smoke" test" that can more accurately find the leak. See if you local AutoZone will rent one (maybe free) to you.

heater core and or backed up evaporator drain tube.

It is possible that the ac drain is clogged blowing some compressed air can clear it and allow water to flow again it is also possible the ac box may be leaking

when installing new o-ring on tube, lubricate o-ring and stick it in water pump. Then pull pressure back on tube and then tighten hold down clamp. problem solved

check out your door seals may need replacing. drive it thru a carwash to locate the spot.
