Have a pressure test performed on the cooling system. It will expose any leaks pretty clearly. If needed, dye can be added to the coolant to pin point a leak's source. Good luck!

It's definetly your water pump going bad. It a fairly easy job when you get the fan clutch removal tool from Autozone. They loan it to you for free.
