material would be a better aquitrd, unconsolidate clay or sandstone rock?

Where is the water table exposed on the earth's surface?

Answer
OK, an aquifer is generally a porous substance (lots of open spaces), so:

which is more porous, the rock or the unlithified gravel?

The second is a bit trickier, because both materials are relatively non-permeable and thus may be aquitards. However, the rock can have fractures and bedding planes whereas the clay won't.

For the third question, think about an open, hand dug well. What is it like in that well where it intersects the water table? Ever dig in the sand at the beach and hit the water table? And then connect your little pond to the nearby lake?

The water table is exposed on earth in pretty well any body of water, although there are exceptions of course (a water body can be disconnected from the water table but usually isn't)

Rivers or lakes for swimming in missouri?

Me and a couple friends are wanting to go on a day trip to a river or lake to hang out and swim maybe. Were in st louis so any place within like an hour of here would be great :)

Answer
There are a number of rivers that have float trips by canoe, kayak or inner tube. Like the Merrimack.
Check out the state parks near st louis. Many of them do have beaches. Mark Twain, Table Rock and Truman all have beaches.
