Hello,

I've been working on a well to build a compressorless geothermal cooling system for my house and I could use some advice. Here goes: Using a hand auger with extentions that a friend and I built, I've dug down to the water table (32'). Along the way, we had some problems with cave ins and I happened across some soon to be discarded pvc pipe (6 inch internal diameter and very heavy duty). We've used this as well casing with the bottom 10' cut to serve as well screen and it now lines the full 32'. However, I seem to be stuck. Every time I send the auger down and pull it out the suction at the bottom of the well pulls more sand and gravel up into the tube so that the net result is that I am no longer getting anywhere though I presume I'm creating a cavity around the bottom of the pipe. Additionally, the casing may be bound up some and doesn't seem to be moving any further down (this may be because the casing is bound or because there is no where for the casing to drop down into since the vaccum draws up more sand and gravel under and into it). Ideally, I'd like to get the casing and screen another 20' down so that I have alot of water column. I have a submersible deep well pump that needs a minimum of 4'' casing but if I can't get the well casing down any further I'm not sure what my best option is. Finding a way to get my casing and screen down further would be ideal and driving a 2'' well inside my 6'' casing is a second best option. Any advice on what and how to proceed would be helpful. By the way the soil is all loose sand and gravel where the gravel is mostly less than 1'' in diameter but occasionally larger. Help?
