Anti freeze leak in small plastic box connected to pump by a thin rubber hose. The small plastic box is located under the pump, near the alternator.

If the box looks similar to this and the leak is a steady one you need a new water pump. The box is a reservoir that connects to the weep hole in the pump and is supposed to catch any small amount of coolant that gets through the pump seal.
Normally it will not leak as there should not be any large amount of coolant in it.
