Well Drilling and Construction Standards

What this domain tests

This domain tests the construction and licensing rules a Nevada well driller must apply before, during, and after drilling. The exam focuses on NAC 534 requirements: who may drill, when a permit is needed, how casing and annular seals protect the well, and how wells are developed, tested, and abandoned.

Core rules and concepts

  • Nevada requires a licensed well driller for construction, deepening, repair, and abandonment of water wells. Licensing is not a substitute for the project-specific permit.
  • In a designated groundwater basin, an appropriative permit from the State Engineer is generally required before drilling. Domestic-use exemptions are narrow and do not waive construction standards or reporting.
  • Casing must be structurally sound, centered, and seated into competent material. The annular space is sealed with an approved grout, typically neat cement or bentonite, placed from the bottom upward so it displaces drilling fluid rather than bridging.
  • The well must have a sanitary seal, and the casing must terminate above finished grade so surface water cannot enter.
  • Development removes drilling fluids and fine material; disinfection follows construction. The driller must then test yield and static/pumping water levels and file the well log.
  • Abandonment requires an approved method, usually filling and sealing so that the borehole cannot transmit water between aquifers.

Worked example

A proposed domestic well is 60 feet deep in a designated basin. A shallow septic plume is present at about 15 feet. The driller must obtain the applicable approval, set casing through the shallow zone, and seal the annular space from total depth to ground surface. A short casing stopping above the plume would leave a vertical pathway for contamination and would fail the protective-seal purpose.

Traps that cost marks

Treating a domestic well as exempt from every Division requirement; grouting from the top down; assuming casing alone seals the annulus; and failing to file an abandonment record.
