Hey all. I recently drilled my own well to about 20' using the popular DIY method using a 3/4" water supply and a 2" PVC pipe drill. I live only a few feet above sea level on top of soft clay and consequently the water table is only about 8 feet below. While it literally takes me less than 10 minutes to drill to the 20' depth, that's as far as I can go. It seems that I hit a very soft and porous sandy layer and the water just disperses into the sand, essentially turning my drilling rig into an injection well. I plan on renting a 200GPM mud pump to continue down, but I'm afraid I'll have the same problem in 5-10 more feet.
With that said, is it possible to reverse the pump to suction and essentially suck my drill down though the sand? I have a feeling I'll get further by pumping the sand out rather than pumping water into the sandy layer. Is this possible, or will the sand be to much for the pump to evacuate even at that small of a lift?
I prefer to go deeper to reduce surface contaminants and improve water quality.
Thanks!
