1. Which Virginia agency administers the regulatory program for water
well systems providers?
A. Virginia Department of Transportation
B. Virginia Department of Health
C. Virginia Department of Labor and Industry
D. Virginia Department of Environmental Quality
Answer: B. Virginia Department of Health
Rationale: The Virginia Department of Health regulates private wells and
water well systems through its applicable environmental health and well-
construction programs, including requirements governing individuals who
construct, alter, repair, or abandon wells.
2. What is the primary purpose of Virginia's water well regulations?
,A. Establish standards for swimming-pool construction
B. Protect groundwater resources and public health by regulating the
construction and management of water wells
C. Regulate municipal electrical distribution
D. Establish residential property tax rates
Answer: B. Protect groundwater resources and public health by regulating
the construction and management of water wells
Rationale: Water well regulations are intended to protect groundwater
from contamination and ensure that wells are properly located,
constructed, maintained, repaired, and abandoned.
3. What is a water well primarily intended to accomplish?
A. Collect surface runoff only
B. Obtain groundwater from a subsurface water-bearing formation
C. Store treated municipal wastewater
D. Divert stormwater into a sewer
Answer: B. Obtain groundwater from a subsurface water-bearing
formation
Rationale: A water well provides a controlled means of accessing
groundwater from an aquifer or other water-bearing formation for an
approved beneficial use.
, 4. Which condition presents the greatest direct risk to groundwater
quality around a poorly constructed well?
A. Properly sealed casing
B. An uncontrolled pathway allowing contaminated surface water to enter
the well or aquifer
C. Correctly installed sanitary protection
D. Proper well development
Answer: B. An uncontrolled pathway allowing contaminated surface water
to enter the well or aquifer
Rationale: Improperly sealed annular spaces, damaged casing, inadequate
grout, or poor surface protection can create pathways for contaminants to
enter groundwater.
5. What is the primary purpose of well casing?
A. Provide structural support and isolate the well from surrounding
formations and undesirable water entry
B. Increase electrical voltage
C. Store disinfectant permanently
D. Measure groundwater temperature
Answer: A. Provide structural support and isolate the well from
surrounding formations and undesirable water entry
, Rationale: Casing stabilizes the borehole and helps protect the well from
collapse and contamination. Proper casing materials and installation are
essential to maintaining well integrity.
6. What is the annular space in a water well?
A. The space between the well casing and the borehole wall
B. The inside diameter of the pump column
C. The space inside the electrical conduit
D. The volume inside the pressure tank
Answer: A. The space between the well casing and the borehole wall
Rationale: The annular space surrounds the casing within the drilled
borehole. It is commonly used for grout or other sealing materials to
prevent unwanted vertical movement of water and contaminants.
7. What is the primary purpose of grouting the annular space?
A. Increase pump horsepower
B. Seal the annular space and help prevent migration of contaminated water
along the outside of the casing
C. Increase the well's electrical conductivity
D. Reduce the pressure-tank volume
Answer: B. Seal the annular space and help prevent migration of
contaminated water along the outside of the casing
