| PRACTICE TEST
1. A property owner submits an application for an on-lot sewage disposal system
permit. What is the FIRST step the Sewage Enforcement Officer (SEO) should take?
A. Issue the permit immediately
B. Conduct a site evaluation and soil testing
C. Approve system design plans
D. Notify the DEP of approval
════════════════════
Correct Answer: B. Conduct a site evaluation and soil testing
Rationale:
The first step in the permitting process is evaluating site suitability through soil testing
and field investigation to determine if the land can support an on-lot sewage system.
,Permits and design approval cannot occur before confirming soil conditions. Options A,
C, and D occur later in the regulatory process.
════════════════════
2. Which soil characteristic most directly affects wastewater percolation rates?
A. Soil color
B. Soil texture
C. Soil temperature
D. Soil odor
════════════════════
Correct Answer: B. Soil texture
Rationale:
Soil texture (sand, silt, clay composition) determines pore space and permeability,
directly impacting how quickly wastewater infiltrates. Color, temperature, and odor are
not primary indicators of percolation capacity.
════════════════════
,3. What is the primary purpose of a percolation test?
A. Determine groundwater contamination
B. Measure wastewater flow rate in pipes
C. Evaluate soil absorption capacity
D. Test septic tank durability
════════════════════
Correct Answer: C. Evaluate soil absorption capacity
Rationale:
A percolation test measures how quickly water drains through soil to assess suitability
for on-lot wastewater disposal. It does not evaluate pipe flow, contamination levels, or
tank strength.
════════════════════
4. Which agency primarily regulates on-lot sewage systems in Pennsylvania?
A. EPA only
B. Local school district
C. Pennsylvania Department of Environmental Protection (DEP)
D. Federal Housing Authority
, ════════════════════
Correct Answer: C. Pennsylvania Department of Environmental Protection (DEP)
Rationale:
The Pennsylvania DEP establishes regulations and oversight for on-lot sewage systems,
while local SEO officers enforce these regulations at the municipal level. EPA provides
broader environmental guidance but does not directly regulate local permits.
════════════════════
5. A soil profile shows high clay content. What is the most likely implication for sewage
disposal?
A. Rapid drainage suitability
B. High infiltration rate
C. Poor drainage and potential system failure
D. No impact on system design
════════════════════
Correct Answer: C. Poor drainage and potential system failure
Rationale:
Clay soils have very low permeability, leading to slow drainage and potential effluent
backup or surfacing. This often requires alternative system designs or soil remediation.
