I am pounding a Sand Point well. I need an idea of a depth.
I am in MN, Forest Lake. I am using 2'' diameter.
thanks

If you are doing this outside make sure you secure your ankle with some 1/4" chain to another pipe or something to keep the skeeters from flying off with you. A frying pan will usually drive them off if they try draining your blood on the spot.
Seriously, check with the city or extension agents and they should be able to help.

I've been waiting for someone else to answer you but......anyway, this is my $0.02 worth.
Why would you "pound" a sand point well tip? Why not wash it down? That is a lot easier...assuming you don't have rock to deal with. If you have rock you will ruin your point/tip before you pound it down far enough anyway. I have experience in using both the metal tip and the plastic/PVC type of tip. Both are good for washing and the metal tip is superior for pounding although it does take a considerable amount abuse on the way down and the viability/condition of the tip/point, when in the water table, is directly related to the efficiency of the well in relation to GPM. If you are installing a pump (Above ground since you are using a 2" pipe.) you'll need to know your GPM before you select a pump so you can match your GPM to the application (irrigation, household use, etc.) or you'll be hampered by cavitation.
As for the static water depth...every place/geography is different. I put one in for my sprinkler system in Rockport Tx. and had water at 8.5 ft. Of course, the water was not potable at that depth but it was fine for irrigation. I actually washed my well down to 24 feet because I already had the pipe available. Regardless of whether you pound or wash you should check every length of pipe you install to see if you have water. You do this with a washer tied to a string and just drop the string and washer down the pipe, securely holding one end of the string, and listen for the splashing sound. Once you hear splashing, make a note of the string length in relation to the ground level and that will be your static water level.
You'll need to check with the local water well guys to inquire the potable water level in your area. I'm now in Kerrville TX. and my well is 799 feet deep! I wouldn't recommend pounding to that depth.

Somewhere between 10 and 1000 feet. Like Torque1st said, check with the city or extension agents and they should be able to help.

Check out http://climate.umn.edu/ground_water_level/ and look at the blue colored wells. That should give you a good idea for your area. Generally, most sand-points are probably dropped in the 20-25' range in that area, I would guess. That provides for enough depth so that recovery is fast enough, although you'll probably reach water before that. It somewhat depends how close to a lake you are, too, which Minnesota has plenty...

When I was a teenager I worked with a driller. Depths producing sufficient volumes can vary greatly. Once you are sufficiently below static depth, you can generally tell if you have a good well by how much water feed by a hose the pipe will handle. If it takes the full volume of a hose without overflowing pipe, you have a good well (after screen is cleaned by sending a hose down to point).

Probably fairly accurate. Around here in a normal year, we find water at 100-300 ft. The last 3 years we have had extremely heavy rain and snow, so I could likely dig a well in my back yard with a shovel. Right now, 6 feet would get me an artesian well with more water than I could use, but 10 years from now, it would most likely be a dry hole again.

In most of mn about 20-25 ft will get you plenty of good water. I'am in princeton and going to put one in this summer in my shop. I left a 2x2 hole in floor so I could do it at a later time. I put one in Ramsey back in the early 80's and at 25 ft I had 2" of clear water out of a engine driven pump for as long as you wanted to let it run.

In Minnesota you must be deeper than 25 feet to clear surface water. I pounded my own 18 years ago and i went to all my neighbors to see what depth they were at, i found water at the same depth as them. I'm up in Grand Rapids.
