My 1994 Jeep Grand Cherokee 4x4 is leaking water

Just recently picked up a 94 Jeep
Grand Cherokee and noticed some
fluid leaking on the ground after
driving it around for a good hour.
Upon further inspection it seems as
though the fluid that is slowly
dripping onto the ground is water
(doesn't taste like anything water).
It's a small consistent drip that
tapers off and stops after about an
hour of being parked.
We've checked the antifreeze
reservoir and the levels haven't
dropped, our temperatures have all
been fine, there doesn't seem to be
any pressure issues with the rad
itself...so this is just all kind of
confusing! Perhaps someone can
shed some light on the situation for
me? :)
