Wyoming Environmental
Practice Questions & Answers (2026)
Environmental questions on the Wyoming exam cover both federal environmental laws and Wyoming-specific disclosure requirements. Federal topics include lead-based paint (pre-1978 housing), asbestos, radon, underground storage tanks, and CERCLA liability. Wyoming has additional state-level environmental disclosure requirements enforced by the Wyoming Real Estate Commission — including Wyoming-specific environmental conditions that affect property use and disclosure. Environmental questions trip up candidates who studied only federal law without reviewing the WY-specific overlay.

Q1. Wyoming's major environmental concern for real estate is:
Explanation
Radon is a naturally occurring radioactive gas that can accumulate in homes. Wyoming has geological formations that can produce elevated radon levels, making radon testing an important part of property inspections.
Q2. A Wyoming property near a former gas station may have:
Explanation
Former gas station sites often have underground storage tank contamination from petroleum hydrocarbons, which can migrate through soil and groundwater. This is a significant environmental issue affecting property value and marketability.
Q3. Under CERCLA (Superfund), an 'innocent landowner' defense in Wyoming protects a property owner who:
Explanation
CERCLA's innocent landowner defense protects buyers who performed appropriate due diligence (typically a Phase I Environmental Site Assessment) before purchase and had no knowledge of contamination. This protects against Superfund liability.
Q4. A Wyoming homebuyer purchases an older home built in 1970. The buyer should be concerned about potential exposure to:
Explanation
Homes built before 1978 may contain lead-based paint, and older construction commonly contained asbestos in insulation, floor tiles, and other materials. Federal law requires lead paint disclosure for pre-1978 homes.
Q5. A Wyoming property owner near an active natural gas operation may need to test well water for:
Explanation
Properties near oil and gas operations in Wyoming may have well water affected by methane or other hydrocarbon contamination. Testing well water for these compounds is an important due diligence step.
Q6. LUST (Leaking Underground Storage Tank) issues in Wyoming primarily affect:
Explanation
Leaking underground storage tanks, which store petroleum products, can contaminate soil and groundwater. Properties near gas stations, farms, or industrial sites with historical fuel storage are at risk.
Q7. Wyoming has significant uranium deposits. A former uranium mine site near a property may indicate risk of:
Explanation
Former uranium mining sites in Wyoming can have elevated radon levels and radioactive soil contamination (including uranium, radium, and thorium), posing risks to nearby property owners.
Q8. A Wyoming property near a coal mine may have a risk of:
Explanation
Coal mining operations can create underground voids that lead to subsidence (sinking or shifting of the ground surface). Wyoming properties near coal mines should be evaluated for this risk.
Q9. A Phase I Environmental Site Assessment (ESA) is designed to:
Explanation
A Phase I ESA identifies recognized environmental conditions (RECs) through research of historical records, agency databases, and a site visit. It does not include soil or water sampling (that is Phase II).
Q10. Wyoming's wind resources have led to rapid growth in wind energy development. A wind energy easement on a property typically:
Explanation
A wind energy easement grants a developer the right to harness wind resources above a property. Landowners receive lease payments, and the easement may restrict certain structures that would interfere with wind flow.
Q11. A Wyoming property in a FEMA Special Flood Hazard Area (100-year floodplain) is:
