1. 1A contractor is siting a new private drinking-water well in New Hampshire. What area must be maintained around the well?

   1. A. A protective well radius
   2. B. An effluent disposal area
   3. C. A state highway right-of-way
   4. D. A recorded property easement

   Answer: A

   Explanation: We 602.06(b) states, "a protective area designated as the protective well radius shall be maintained around every private commercial or non-commercial drinking water well." Therefore the required area is the protective well radius.

   Reference: We 100-800 — We 602.06(b)

2. 2Site conditions prevent full setbacks. What quality must guide selection of the alternate well location?

   1. A. It places the well at the parcel center
   2. B. It minimizes the length of the access road
   3. C. It is closest to the building foundation
   4. D. It maximizes setback distances to the greatest extent possible

   Answer: D

   Explanation: We 602.13(a) requires the contractor to identify an alternate location that "maximizes setback distances to the greatest extent possible." That criterion controls the selection.

   Reference: We 100-800 — We 602.13(a)

3. 3During bedrock drilling, which fracture-related occurrence must be observed and recorded?

   1. A. Depth to static water before pump installation
   2. B. Depths to fractures yielding readily observable water
   3. C. Depth to bedrock below unconsolidated material
   4. D. Total depth of the completed well

   Answer: B

   Explanation: We 602.20(b)(3) requires recording the "Depths to fractures yielding readily observable amounts of water." This is a direct drilling observation.

   Reference: We 100-800 — We 602.20(b)(3)

4. 4During construction of a drilled gravel well, what formation information must be recorded?

   1. A. Treatment chemical dosages
   2. B. Only the final pump model
   3. C. Only the owner's water bill
   4. D. Material types and layer thicknesses

   Answer: D

   Explanation: We 602.23(c)(1) requires recording the "Types of materials encountered during construction and the thickness of the layers." Those observations describe the formation.

   Reference: We 100-800 — We 602.23(c)(1)

5. 5During construction, when must well yield be measured before the final test?

   1. A. Whenever a readily observable change in yield occurs
   2. B. At fixed ten-foot drilling intervals only
   3. C. Only when casing is delivered
   4. D. Only after the completion report is filed

   Answer: A

   Explanation: We 602.33(a) states, "Well yield shall be measured periodically during well construction when there is a readily observable change in yield." Observable yield changes trigger measurement.

   Reference: We 100-800 — We 602.33(a)

6. 6When may a well casing be terminated below grade under We 602.35?

   1. A. Whenever the well is more than 100 feet from a house
   2. B. Whenever the owner prefers a hidden wellhead
   3. C. When an above-grade termination would pose a hazard
   4. D. Only when the casing is plastic

   Answer: C

   Explanation: We 602.35(a)(1) requires that "The location of the well would pose a hazard if the casing extended above the ground surface." Owner preference alone is not the stated condition.

   Reference: We 100-800 — We 602.35(a)

7. 7Who may seal a well in New Hampshire?

   1. A. A water well contractor licensed in New Hampshire
   2. B. Any property owner with excavation equipment
   3. C. Any licensed electrician
   4. D. Only a pump manufacturer

   Answer: A

   Explanation: We 604.02(b) states, "A well shall be sealed only by a licensed New Hampshire water well contractor" holding a valid license under RSA 482-B. The work is restricted to that license class.

   Reference: We 100-800 — We 604.02(b)

8. 8Which location information is required on a New Hampshire well completion report?

   1. A. Geographic coordinates only
   2. B. Geographic coordinates, available emergency-service address, and tax map and lot number
   3. C. Emergency-service address and tax map and lot number, but no coordinates
   4. D. Geographic coordinates and emergency-service address, but no tax map and lot number

   Answer: B

   Explanation: We 801.01(a)(3) requires location by "Geographic coordinates provided by global positioning technology," the available enhanced 911 address, and the tax map and lot number.

   Reference: We 100-800 — We 801.01(a)(3)

9. 9A proposed protective well radius fits entirely within the parcel. Which placement satisfies the listed containment options?

   1. A. Wholly in a public-road surface
   2. B. Wholly on-lot
   3. C. Wholly in an unrecorded neighboring yard
   4. D. Wholly in a future building footprint

   Answer: B

   Explanation: We 602.08(b)(1) expressly permits the radius to be contained "Wholly on-lot." The other choices do not match the rule's listed containment methods.

   Reference: We 100-800 — We 602.08(b)(1)

10. 10Before constructing at a reduced-setback location, what risk must the contractor communicate to the property owner?

    1. A. The possibility of higher annual license fees
    2. B. The potential for contamination at the alternate location
    3. C. The chance that the board will change exam dates
    4. D. The likelihood of a property-tax reassessment

    Answer: B

    Explanation: We 602.13(b) directs the contractor to "Alert the property owner of the potential for contamination at the proposed alternate location." The notice concerns contamination risk.
