I had a soil guy come out and found out what was wrong. I am apparently in the Mississippi Glacier melt or something along those lines. What I thought was clay was a silt matter. The core sample below my water line showed 20-25% clay which was holding water. At the water level that I can't seem to surpass is this silt. I have no specific leak other than everywhere at that level. He suggested that I put sodium bentonite in as high as I want the water to go. Also to cover down into the bottom to make sure that it doesn't well up from pressure. Now I need to find a Semi Load of Bentonite that will deliver to Southern Illinois. Any suggestions from the experts. Bulk suppliers that are local?
