1. 1A Virginia master-exam applicant documents 48 hours of formal vocational training. What minimum supervised practical experience must also be verified?

   1. A. One year
   2. B. Three years
   3. C. Six years
   4. D. Eight years

   Answer: C

   Explanation: The controlling regulation requires "Six years of practical experience in the drilling, installation, maintenance, or repair of water wells or water well systems under the supervision of a certified master water well systems provider or other equivalent experience as approved by the board and 48 hours of formal vocational training in the trade" for the master examination. One and three years are lower certification thresholds.

2. 2While planning bore advancement for local geology and aquifer conditions, which certified role makes the method decision?

   1. A. The water well systems provider
   2. B. The water-testing laboratory
   3. C. The pressure-tank manufacturer
   4. D. The utility owner locating an easement

   Answer: A

   Explanation: Virginia assigns the judgment directly: "The method of advancement of the well bore ... shall be determined by the water well systems provider relative to local geologic and aquifer conditions." The other parties have different roles.

3. 3What three functions must Virginia well casing perform?

   1. A. Maintain the bore, convey water, and protect withdrawn-water quality
   2. B. Develop the aquifer, disinfect the system, and analyze coliform
   3. C. Store pressure, control pump current, and vent the tank
   4. D. Locate utilities, establish property lines, and issue the permit

   Answer: A

   Explanation: The casing rule requires it to "maintain the well bore by preventing its walls from collapsing, provide a channel for the conveyance of water, and protect the quality of the water withdrawn." The other groups belong to different tasks.

4. 4A bored Virginia hole finds no water and casing was never installed. What abandonment plug is required?

   1. A. A two-foot-thick grout plug placed at least five feet below ground
   2. B. A one-foot clean-fill cap placed at the water level
   3. C. A twenty-foot filter pack placed from the surface
   4. D. No plug if the cuttings are returned

   Answer: A

   Explanation: The rule requires: "A two-feet-thick plug of grout shall be placed at a minimum of five feet from the ground surface." Cuttings or clean fill occupy the remaining intervals.

5. 5A Virginia well is constructed in a floodplain. What minimum vertical protection is required at its terminus?

   1. A. 18 inches above the annual flood level
   2. B. 12 inches above ordinary ground regardless of annual flood level
   3. C. 6 inches above the seasonal high water table
   4. D. Flush with the annual flood level

   Answer: A

   Explanation: Floodplain construction must include "extending the well terminus 18 inches above the annual flood level" and positive drainage. The alternatives use other references or change the elevation.

6. 6Where must the sample tap for a Virginia Class III well be located relative to treatment equipment?

   1. A. At or near system entry and before treatment devices
   2. B. After all treatment devices
   3. C. Only at the pressure-tank drain
   4. D. Only at the farthest fixture

   Answer: A

   Explanation: The rule says: "A sample tap shall be provided at or near the water entry point into the system so that samples may be taken directly from the source" and permits a nearby first tap only if it precedes treatment devices. The other points can reflect treated or distributed water.

7. 7Before a master assigns a crew member to operate drilling machinery, what qualification must be confirmed?

   1. A. Qualification by training or experience
   2. B. Authorization to enter the private-well property
   3. C. Training to collect a bacteriological water sample
   4. D. Approval to mix and place annular grout

   Answer: A

   Explanation: The machinery rule permits "only those employees qualified by training or experience to operate equipment and machinery." Site access, sampling, and grouting are real qualifications or permissions, but they do not establish machinery-operating competence.

8. 8Which load categories must Virginia private-well materials have enough strength to withstand?

   1. A. Hydraulic, lateral, and bearing loads
   2. B. Only axial pump weight
   3. C. Only internal tank pressure
   4. D. Only screen-collapse load

   Answer: A

   Explanation: The general materials rule requires "sufficient strength to withstand hydraulic, lateral, and bearing loads." The alternatives cover only narrower or different system loads.

9. 9Which component set remains within the defined water-well system up to its building-system connection?

   1. A. Well, pump, tank, pipe, and wire
   2. B. Bore, casing, screen, and annular grout
   3. C. Sample tap, treatment device, and house plumbing
   4. D. Drill rig, drill stem, bit, and mud pump

   Answer: A

   Explanation: A water-well system includes "the water well to reach groundwater and the well pump and tank, including pipe and wire" through its connection boundary. The alternatives are real well-construction, distribution, or drilling-equipment groups rather than the defined system set.

10. 10Which Virginia certification level requires proof of at least six years of supervised practical water-well experience?

    1. A. Master
    2. B. Journeyman
    3. C. Trainee
    4. D. All three levels

    Answer: A

    Explanation: Section 54.1-1129.1 establishes "(iii) master, which shall require proof of at least six years of practical experience" under a certified master. The journeyman and trainee thresholds are three and one years.
