I currently am suffering from a coolant leak, and when I originally took the front passenger wheel off to get a better look, it appeared it was coming from the water pump. I scheduled an appt with an independent shop, and asked to have them not only do some routine maintenance (serpentine belt, tensioner, idler pulley), but also to investigated the leak I had.
Turns out, I have two coolant leaks (and as a result, they have to order some more parts, and then everything will be taken care of, so nothing was done which was fine). One is the water pump, but the other is the crossover pipe above the water pump where the thermostat is. It is possible you have a leak either at the water pump, or the crossover pipe for the thermostat. Turns out I have leaks on both, but both coolant hoses themselves that go to the water pump were bone dry, so I knew it wasn't them.
If you're still unsure, I would contact an independent shop you trust, and have them take a look at it to be sure.
