Oh dude... Believe me when I say to you that you don't want to know. My wife drives the '02 vintage which I'm confident are similar. I've had two coolant related issues between 60k and 80k on the odometer. The first was a bad water pump (very expensive because they use a special kind that you won't find used or remanufactured easily). The second time was a stem at the back of the block that was cracked. Each time the coolant leaked slowly (but in an accelerating manner).
I hope it's something simple for you, but I kinda doubt it.

My 1st guess would be the lower intake gasket. They usually leak near the drivers side . Your car needs to be pressure tested to make a proper diagnosis, but make sure you mainly check for that, and small leaks from the water pump, also very common. Note- if your intake is leaking, it is a costly repair, GM has extended the warranty on it up to 70k. Dont put it off it the intake is leaking, they can also leak internal from the gasket being broken and the coolant getting into the oil can cause severe engine damage. Good luck

If you can't see it, it's leaking through an intake or head gasket.
On the ground it typically is around the hose connections or pierced radiator. Could be the water pump seal around the shaft or its gasket.

your most likely problems with that car are water pump, look on passenger side when car is hot and radiator under pressure if you dont have a pressure tester it will be leaking onto the drive belt from bottom of waterpump, or look on drivers side where engine and trans connect there are some pockets on top of trans where it will collect if its the intake leaking. these are common and any reliable shop or dealership will know these

Water pump, heater hoses, radiator hoses, radiator, heater core, head gaskets, frozen block, heads, loose hose clamps. If you'd like to find out quickly go to your Pontiac Dealer and get a cooling system pressure check

your best bet:
radiator or hoses.
Check the floor and the dashboard and any compartments to make sure it isnt leaking into your car:]
good luck!
It could have to do with your intake gasket
