The next day I went back out to run the actual perc test. Now in a perc test, after the soil (or in this case, the garbage) has been saturated you fill the hole with water and measure the time it takes for the water to drop i.e. minutes per inch. So I filled the hole with water and before I could fill the next hole, the water level, as it had before, dropped completely. I concluded that garbage has a really low (or in other words, a really fast) perc rate.
I decided to switch gears and try running a perc test in the native soil. I dug two holes in the native soil and started saturating them.I'm pretty sure these tests are going to be much different. I saturated the holes but didn't have time to run the tests the next day, (I'll have to start over) but came back four days later to see that one of the holes still had water in it. I think this soil is a little less permeable than the garbage.
