The results are the same. What you see is a bore-hole of about 45 meter depth, and it is actually active, it is the effective part of the bore-hole is not starting already at 45 meters, it starts to recharge to the bore-hole at about 29 meter. And, what you see here, is that, first of all, there is not a homogeneous aquifer prevailing here.
You have the geological cross-section, and in the geological cross-section you see under the top soil the thick weathered part of the granitic area and then you have the fractured zone of the granitic body, and here is the basement in the depth of more then 40 meters. And the recharge, the active part is not in the hard rock part, it is in the weathered zone, and it again, it shows you that not the whole depth of this weathered zone is active, just part of it is active and in this case 2.5 meters from here to here is an inflow at about 5 meters, so it means from about 23 meter to 18 meter, again you have a recharge.
Of interest was our sampling before we started: the water table at the beginning had been at 5 meter and 87 and, before pumping started, so under natural understood conditions, we made a sampling in the depth of 6 meter and in the depth of 40 meter.
We made analyses of these 2 water samples and it was astonishing for us that the both samples had the same isotopic composition in O-18 -2.2 and in Deuterium around about -15.4 showing that this whole body must be very well mixed. It was not pumped before, so therefore no mixing happened by pumping, this well was kept under quite conditions and therefore this kind of, this must be mixing under natural conditions, though most probably we can find here relatively high velocities in the saturated zone of the weathered part.
