NEBRASKA SOIL EVALUATOR EXAMINATION
COMPLETE QUESTIONS AND DETAILED SOLUTIONS
LATEST UPDATE THIS YEAR JUST RELEASED
1.
During a Nebraska onsite wastewater soil evaluation, which
characteristic is most important for determining whether the soil can
adequately treat and disperse effluent?
A. Soil color alone
B. Design-controlling soil and subsurface characteristics
C. Property tax classification
D. Vegetation height
Answer: B
Rationale: A soil evaluation examines design-controlling characteristics
such as soil type, structure, permeability, absorption capacity, and
limiting subsurface conditions that influence system performance. (
2.
Which Nebraska agency administers professional certification
requirements for individuals performing regulated onsite wastewater
soil evaluation activities?
A. Nebraska Department of Agriculture
B. Nebraska Department of Transportation
,C. Nebraska Department of Water, Energy, and Environment
D. Nebraska Game and Parks Commission
Answer: C
Rationale: DWEE administers Nebraska's Onsite Wastewater Program,
including professional certification for Soil Evaluators and other onsite
wastewater professionals. (
3.
What is the primary purpose of evaluating soil and subsurface
conditions before selecting an onsite wastewater absorption area?
A. To determine property resale value
B. To establish suitable wastewater treatment and dispersal conditions
C. To estimate annual rainfall
D. To identify landscaping preferences
Answer: B
Rationale: Soil evaluation identifies conditions controlling treatment
and dispersal so that an onsite absorption system can be appropriately
located and designed. ()
4.
Which soil characteristic generally describes how readily water can
move through connected soil pores under appropriate conditions?
,A. Soil permeability
B. Soil color
C. Soil temperature
D. Soil organic residue
Answer: A
Rationale: Permeability describes the ability of soil to transmit water,
making it an important consideration when evaluating wastewater
absorption suitability.
5.
Why should a Soil Evaluator identify restrictive or limiting layers
beneath a proposed absorption area?
A. They can influence wastewater movement and available treatment
depth
B. They determine the property's assessed value
C. They establish the property's zoning district
D. They eliminate the need for field observations
Answer: A
Rationale: Restrictive layers can impede vertical movement, reduce
treatment capacity, alter groundwater interactions, and affect whether
conventional absorption is appropriate.
6.
, Which condition would generally warrant particularly careful
investigation during an onsite wastewater soil evaluation?
A. Deep, uniform soil with favorable structure
B. Shallow groundwater or a restrictive subsurface layer
C. Recently mowed grass
D. A large mailbox
Answer: B
Rationale: Shallow groundwater and restrictive layers can substantially
affect treatment, dispersal, separation distances, and system suitability.
7.
Under Nebraska Title 124 terminology, what does “soil evaluation”
include beyond simply examining surface soil texture?
A. Only laboratory chemical testing
B. Investigation of soil and subsurface design-controlling characteristics
C. Only measuring property boundaries
D. Only measuring annual precipitation
Answer: B
Rationale: Nebraska defines soil evaluation broadly to include
investigation, examination, testing, and reporting of soil and subsurface
characteristics controlling system design. (DWEE NE)
