o Prohibited areas: Floodplains 100-year, within 100 ft of water supply wells, 50 ft of streams/reservoirs, on steep slopes (>25% for conventional, >15% alternative with restrictions)

  • System Sizing Requirements: o Bedroom count + fixture units → daily design flow (gpd) o Absorption area (sq ft) required = design flow / loading rate o Trench length = absorption area / trench width o Loading rate (gal/day/sq ft) based on percolation test or soil texture (fast = 1.2; slow = 0.2 gpd/sq ft)

3. What is the minimum required depth for a deep-hole soil test to identify limiting zones? A) 48 inches B) 60 inches C) 72 inches D) 36 inches Answer: B Rationale: PA DEP regulations require deep holes to be excavated to a minimum of 60 inches or until a limiting zone (bedrock, seasonal high water table) is encountered. 4. Which of the following is considered a "limiting zone" for a conventional on-lot sewage system? A) Sandy loam soil to 48 inches B) Seasonal high water table (SHWT) within 60 inches of the surface C) Gravel layer at 36 inches D) Red clay at 48 inches Answer: B Rationale: Seasonal high water table is a limiting zone; systems require a minimum separation of 12 inches above SHWT or 24 inches depending on design.

5. The "perc test" (percolation test) measures: A) Nutrient content of the soil B) The rate at which water moves through the soil (minutes per inch) C) Soil pH D) Depth to bedrock Answer: B Rationale: Percolation tests determine the soil's absorption rate, used to size the absorption area. 6. A conventional absorption trench must be set back a minimum of how many feet from a private water supply well? A) 50 feet B) 75 feet C) 100 feet D) 150 feet Answer: C Rationale: PA Title 25 Chapter 73 requires a minimum 100-foot horizontal separation from the absorption area to a water supply well.

9. What is the maximum allowable slope for a conventional on-lot sewage system (absorption trench)? A) 10% B) 15% C) 25% D) 35% Answer: C Rationale: Conventional absorption trenches are not permitted on slopes exceeding 25%. 10. The "scum layer" in a septic tank should never exceed what fraction of the liquid depth? A) 1/ B) 1/ C) 2/ D) 1/ Answer: B Rationale: Excessive scum (more than 1/3 of liquid depth) indicates need for pumping.

11. The "sludge layer" depth in a septic tank can be measured by: A) Visual inspection only B) Sludge judge or other calibrated stick C) Using a shovel D) Smelling the tank contents Answer: B Rationale: A sludge judge or calibrated stick is used to measure sludge depth. 12. The primary function of a distribution box is to: A) Separate solids from liquids B) Evenly distribute effluent to multiple absorption trenches C) Filter out bacteria D) Store scum Answer: B Rationale: A distribution box splits effluent equally among trenches to prevent overloading one line.

15. When conducting a deep-hole test, the SEO must record: A) Soil texture and color B) Depth to bedrock or seasonal high water table C) Presence of mottling (redoximorphic features) D) All of the above Answer: D Rationale: All observations (texture, limiting zones, mottling, structure) are required. 16. What is the minimum vertical separation distance between the bottom of an absorption trench and a limiting zone (e.g., SHWT or bedrock)? A) 6 inches B) 12 inches C) 24 inches D) 36 inches Answer: B Rationale: PA regulations typically require 12 inches of undisturbed soil above the limiting zone.

17. A sewage enforcement officer observes "mottling" (redoximorphic features) in a soil pit at 24 inches. This indicates: A) The soil is well-drained B) Seasonal high water table at that depth C) High organic content D) Bedrock presence Answer: B Rationale: Mottling (gray/orange splotches) indicates periodic saturation – evidence of seasonal high water table. 18. What is the maximum allowable percolation rate (slowest) for a conventional absorption trench system? A) 30 minutes per inch B) 60 minutes per inch C) 90 minutes per inch D) 120 minutes per inch Answer: D

Answer: B Rationale: Surface breakout indicates system failure; repair permit is required.

21. The formula used to calculate required absorption area (square feet) is: A) Design flow (gpd) × loading rate (gpd/sq ft) B) Design flow (gpd) ÷ loading rate (gpd/sq ft) C) Loading rate ÷ design flow D) Trench length × trench depth Answer: B Rationale: Absorption area = design flow ÷ loading rate. 22. For a site with a perc rate of 30 minutes per inch, what is the typical loading rate? A) 0.2 gpd/sq ft B) 0.5 gpd/sq ft C) 0.8 gpd/sq ft D) 1.2 gpd/sq ft

Answer: D Rationale: Faster perc (30 min/inch) allows higher loading rate (1.2 gpd/sq ft).

23. For a site with a perc rate of 120 minutes per inch, the loading rate is typically: A) 0.2 gpd/sq ft B) 0.4 gpd/sq ft C) 0.6 gpd/sq ft D) 1.0 gpd/sq ft Answer: A Rationale: Slow perc (120 min/inch) requires lower loading rate (0.2 gpd/sq ft). 24. A 4-bedroom home requires a design flow of 600 gpd. With a loading rate of 0.4 gpd/sq ft, what is the required absorption area? A) 150 sq ft B) 240 sq ft C) 1,500 sq ft D) 2,400 sq ft

Answer: B Rationale: Trenches are typically 18-24 inches deep to the bottom of gravel.

27. When a property is located in a floodplain (100-year flood zone), the SEO must: A) Approve a conventional system B) Deny the permit unless an elevated system (mound) is used C) Ignore floodplain status D) Approve any system Answer: B Rationale: Conventional systems are not permitted in floodplains due to flooding potential. 28. Which soil structure is most favorable for wastewater absorption? A) Massive (no cracks) B) Platy C) Granular / blocky D) Prismatic

Answer: C Rationale: Granular or blocky structure allows water movement; massive structure restricts it.

29. The primary function of an aerobic treatment unit (ATU) is to: A) Remove solids only B) Provide secondary treatment (break down organic matter) using oxygen C) Store effluent D) Pump effluent to a holding tank Answer: B Rationale: ATUs use oxygen to treat wastewater to a higher level (secondary treatment). 30. In an elevated sand mound system, the "pressure distribution network" serves to: A) Increase flow to the mound B) Uniformly distribute effluent over the sand bed C) Aerate the sand D) Remove scum

Answer: B Rationale: Mounds require 12 inches of sand fill above the natural soil limiting zone.

33. A low-pressure pipe (LPP) system is characterized by: A) Small-diameter laterals with small orifices B) Large trenches with gravel C) Aeration tank only D) Drip tubing above ground Answer: A Rationale: LPP uses 1.5-2 inch laterals with small orifices (0.125-0.25 inches) for even distribution. 34. The "sludge judge" is used to measure: A) Scum thickness B) Sludge depth in a septic tank C) Liquid depth D) Effluent clarity

Answer: B Rationale: A sludge judge is a clear tube with a flap that captures sludge and liquid.

35. When should a septic tank be pumped? A) Every year B) Every 3-5 years (or when sludge/scum exceed limits) C) Never D) Every 10 years Answer: B Rationale: Pumping frequency depends on tank size, usage, and sludge/scum accumulation. 36. An SEO issues a permit based on a site evaluation. If the homeowner builds a garage over the absorption area, the SEO should: A) Ignore it B) Issue a violation notice and require removal/relocation C) Approve the garage D) Revoke the permit retroactively
