FLORIDA SEPTIC TANK CONTRACTOR EXAMINATION
COMPLETE QUESTIONS AND DETAILED SOLUTIONS
LATEST UPDATE THIS YEAR JUST RELEASED
1.
Before beginning construction of a new onsite sewage treatment and
disposal system, what should a septic tank contractor verify first?
A. That the homeowner has purchased a maintenance contract
B. That the required construction permit has been properly issued
C. That the drainfield has already been covered
D. That the septic tank has been pumped
Answer: B
Rationale: Construction should proceed according to an approved
permit and authorized design, ensuring required site and installation
conditions are satisfied.
2.
Which primary purpose does an onsite sewage treatment and disposal
system serve when properly designed and constructed?
A. Increasing groundwater pressure
B. Eliminating all household wastewater production
C. Treating and disposing of wastewater without creating public-health
hazards
D. Providing drinking water storage
,Answer: C
Rationale: A properly functioning OSTDS treats wastewater and
disperses effluent while protecting public health and environmental
resources.
3.
Why is a suitable soil evaluation important before selecting the location
of a conventional septic drainfield?
A. Soil conditions influence wastewater absorption and treatment
performance
B. Soil determines the household's daily water consumption
C. Soil eliminates the need for a septic tank
D. Soil determines the contractor's registration expiration date
Answer: A
Rationale: Soil characteristics strongly affect hydraulic conductivity,
treatment capability, groundwater protection, and appropriate
drainfield construction.
4.
A contractor discovers that actual site conditions differ substantially
from the approved construction plan. What is the most appropriate
response?
A. Proceed using personal judgment without documentation
B. Modify the system without notifying anyone
,C. Stop and obtain appropriate approval for the required change
D. Cover the system immediately
Answer: C
Rationale: Significant field changes can affect compliance,
performance, and permitting, so unauthorized deviations should not
simply be constructed.
5.
Which component normally receives wastewater first after it leaves a
building through the building sewer?
A. Drainfield
B. Septic tank
C. Groundwater monitoring well
D. Soil absorption mound
Answer: B
Rationale: In a conventional septic system, wastewater generally enters
the septic tank before clarified effluent moves toward dispersal.
6.
What is the primary function of a septic tank during normal wastewater
treatment?
A. Completely disinfecting all wastewater
B. Separating solids and allowing anaerobic treatment before effluent
, dispersal
C. Increasing wastewater temperature
D. Pumping wastewater directly into groundwater
Answer: B
Rationale: Septic tanks provide settling, flotation, and anaerobic
decomposition while retaining solids and transmitting liquid effluent.
7.
Why should a contractor prevent construction equipment from
unnecessarily compacting the designated drainfield area?
A. Compaction can reduce soil infiltration and hydraulic performance
B. Compaction increases septic tank volume
C. Compaction disinfects the soil
D. Compaction improves wastewater treatment automatically
Answer: A
Rationale: Excessive soil compaction can alter pore structure and
reduce the soil's ability to accept and transmit effluent.
8.
Which condition would most likely create a serious concern when
selecting an onsite sewage disposal area?
A. Adequate suitable soil
B. Appropriate separation from limiting conditions
