Nev. Admin. Code § 534.378 - Construction of well: Measures required if artesian condition is encountered
1. If an artesian condition is encountered in
a well, the well driller shall, in addition to complying with the provisions of
subsections 2 and 3 of
NRS
534.060, ensure that unperforated casing
extends through the confining strata above the artesian zone. The annular space
between the casing and the walls of the borehole must be sealed by placing neat
cement, cement grout or bentonite chips by tremie pipe in an upward direction
from the top of the artesian zone to the level necessary to prevent the leakage
of artesian water above or below the surface. If bentonite chips are used, the
chips must be placed in accordance with the manufacturer's
specifications.
2. Any flow of
artesian water must be stopped completely in the manner set forth in subsection
3 of
NRS
534.060 before the drill rig is removed from
the drill site.
