ground surface to the total depth of the drilled borehole, the elevation and
designation of geological formations, water levels, formations penetrated, and
other details to describe the proposed well completely;
(vi) Screen locations, size of screen
openings, and screen intervals;
(vii) The location of any blast charges, if
available; and
