Water on the floor could come from bad door weather striping. It could come from a plugged sunroof drain hose. It could come down the firewall from a dry weather seal in the cowl. It come from rust holes in the fire wall.

My '96 Alero had the leaking cowl and it took a couple years to find it. The water ran down the firewall behind the carpet. It would rain and a puddle formed on the drivers side floor. --- I drilled a hole through the carpet and floor to drain it.

after taking a closer look it seems to be leaking out of the floor air vents because my drivers foot just got wet. also saw water dripping from underneath glove box area. would this problem occur with no rain outside because its been dry for a week now.

That would be your HVAC heater core drain. There's a rubber hose low and centered on the firewall behind the engine. They sometimes plug up. -- If it smells sweet like coolant, it could be a heater core leak.

Same problem with my 2005. pulled back the front carpet and discovered the drain hose from A/C was pulled out of the rubber grommet where it goes through the floor board. Condensation was running under the front carpet and seat and collecting in rear passenger side. Hose could come out with powerful suction when cleaning carpet. Added duct tape to prevent reoccurrence. Easy test would be to run A/C and see whether or not the condensation is dripping on the pavement under the car.
