Introduction
The Florida Septic Tank Contractor Licensing Exam evaluates the competency
of professionals responsible for installing, repairing, and maintaining onsite
sewage treatment and disposal systems (OSTDS). The assessment measures
knowledge of Florida regulations, soil evaluation, system design, installation
procedures, environmental protection standards, and contractor ethics. Questions
combine foundational theory with applied field scenarios to assess decision-
making in real-world situations. The exam consists of multiple-choice questions
that require candidates to analyze site conditions, apply engineering principles,
follow regulatory requirements, and demonstrate professional judgment.
Successful candidates show both technical proficiency and an understanding of
public health and environmental protection responsibilities.
,Section 1 (Questions 1–35)
1. A septic system is primarily designed to perform which function?
A. Transport sewage to municipal plants
B. Store stormwater runoff
C. Treat and disperse wastewater onsite
D. Produce fertilizer for agriculture
Rationale: Septic systems treat household wastewater through settling and soil
filtration before dispersing it into the soil.
2. Which component of a septic system is responsible for separating solids
from liquids?
A. Distribution box
B. Drainfield
C. Septic tank
D. Inspection port
Rationale: The septic tank allows solids to settle as sludge and lighter materials to
float as scum.
3. The drainfield primarily treats wastewater through which process?
A. Chemical chlorination
B. Ultraviolet sterilization
C. Soil filtration and biological activity
D. Evaporation
Rationale: Soil microbes break down contaminants while the soil filters remaining
particles.
, 4. A soil with very slow permeability would most likely cause which issue?
A. Excess infiltration
B. Surface ponding of effluent
C. Reduced tank settling
D. Tank corrosion
Rationale: Slow soils cannot absorb wastewater quickly enough, leading to surface
ponding.
5. Which agency primarily regulates onsite sewage treatment systems in
Florida?
A. EPA
B. County zoning board
C. Florida Department of Health
D. Department of Agriculture
Rationale: Florida’s OSTDS program is administered by the Florida Department
of Health.
6. A contractor performing septic installation without a license in Florida may
face which consequence?
A. System redesign requirement
B. Fines and legal penalties
C. Drainfield replacement
D. Permit suspension only
Rationale: Licensing laws impose financial and legal penalties for unauthorized
work.
