Leaking Engine Coolant?

I did a walk-around on my 97 Lumina and I noticed that a neon greenish-yellowish fulid was leaking onto my driveway. I kind of located the source of the spill comming from near the alternator. Engine coolant maybe? What could this be and whats the best solution for this?

engine coolant.
and it could be a water pump or the intakes leaking........

I had coolant leaking from the same area last year. Turned out to be a leaky gasket on the water pump. The coolant was falling onto the serpentine belt and getting thrown up against the hood and carried back towards the alternator. Replacing the pump and gasket fixed the problem. I hope yours is that simple.
