(iii) The well test method and allowable tolerance;

(iv) The locations of all caisson construction joints and porthole assemblies on drawings, if a radial water collector is proposed;

(v) From the 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

(viii) Existing well test data, including:

(A) Test pump capacity-head characteristics;

(B) Static water level;
