  1. Wash Boring* Method -sorry- What I don't understand about this method is where the soil sample is going. "A casing is driven with a drop hammer. A hollow drill rod with chopping bit is inserted inside the casing. Soil is loosened and removed from the borehole using water or a drilling mud jetted under pressure." Is The soil removed mixed with the jetted water?? I mean completely mixed, with no form like the shelby pipe, but a liquid with soil particles? Or How exactly, step by step, is the sample extracted? D: Please help, I really dont understand.
