AWWA (American Water Works Association) Cross
Connection Control Specialist exam 1 questions with
accurate answers
1. What is the primary purpose of a cross-connection control program?
A) To reduce water consumption
B) To prevent contamination of the potable water supply
C) To improve water pressure
D) To reduce water treatment costs Ans✓✓✓ B) To prevent
contamination of the potable water supplyExplanation: The main goal of
a cross-connection control program is to protect the public water system
from potential contamination due to backflow.
10. Which of the following is NOT a common type of backflow
prevention device?
A) Pressure vacuum breaker (PVB)
B) Reduced pressure zone (RPZ) valve
C) Double check valve (DCV)
D) Flow restrictor valve Ans✓✓✓ D) Flow restrictor valve
11. Which of the following types of backflow prevention devices would
be appropriate for a high-hazard system where both backsiphonage and
backpressure are possible?
A) Double Check Valve Assembly (DCVA
B) Pressure Vacuum Breaker (PVB)
C) Reduced Pressure Zone (RPZ) Valve
, D) Atmospheric Vacuum Breaker (AVB) Ans✓✓✓ C) Reduced
Pressure Zone (RPZ) Valve
12. What should be done if there is no accessible shut-off valve before
the backflow prevention device in a system?
A) The backflow preventer should be installed anyway, as it is the most
important part of the system.
B) A shut-off valve should be installed before the backflow preventer.
C) The system should be left without a shut-off valve and rely solely on
the backflow preventer.
D) The backflow preventer can be installed at any point in the system,
regardless of the shut-off valve location. Ans✓✓✓ B) A shut-off valve
should be installed before the backflow preventer.
13. Which type of backflow prevention device is required for an
irrigation system that uses chemical additives?
A) Atmospheric Vacuum Breaker (AVB)
B) Double Check Valve Assembly (DCVA)
C) Reduced Pressure Zone (RPZ) Valve
D) Pressure Vacuum Breaker (PVB) Ans✓✓✓ C) Reduced Pressure
Zone (RPZ) Valve
14. Which of the following is NOT a factor in determining the hazard
level of a cross-connection?
A) The potential health risk posed by the substance in the system.
B) The location of the cross-connection in the water distribution system.
