To be sure, either search for "bucket test" on the forum, or take a 5 gal bucket. Drill a bunch of holes in the bottom, of varying size, 1/8" to 3/8". Take about 4"-6" of your dirt and pack it in the bottom of the bucket. Set it on a couple of bricks or something else to get it up off of the ground a bit and fill'er up with water. check in 24 hrs and see how much leaked out.
