I'd first have the water tested, then see what you may have to do to make it potable. It's possible all you need is something like a sand filter to remove a few particles.
You may want to ask this in the pumps and wells section...you'll probably get more helpful responses there.
Basically, most well pumps should handle that rise and distance. You'd need a bladder tank for some pressurized storage in the cabin so the pump doesn't have to run when you just want to brush your teeth.
