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

Q1. Lead-based paint disclosures are required in Nevada when selling a home built before:

Federal law (Residential Lead-Based Paint Hazard Reduction Act) requires sellers of homes built before 1978 to disclose known lead-based paint hazards and provide an EPA pamphlet to buyers.
Q2. Radon is a naturally occurring radioactive gas that enters buildings primarily through:
Explanation
Radon seeps into buildings through cracks and openings in the foundation from the underlying soil. Nevada has areas with elevated radon levels, and testing is recommended for buyers concerned about radon exposure.
Q3. CERCLA (the Superfund law) imposes liability for hazardous waste cleanup on:
Explanation
CERCLA imposes strict, joint, and several liability on potentially responsible parties (PRPs) including current owners, prior owners, operators, and arrangers. Nevada properties near mining or industrial sites may have CERCLA concerns.
Q4. In Nevada's desert environment, which environmental issue is commonly disclosed during real estate transactions in older commercial properties?
Explanation
Underground storage tanks (USTs), especially older ones at former gas stations and industrial sites, are a significant environmental concern in Nevada. Leaking USTs can contaminate soil and groundwater and create significant cleanup liability.
Q5. Asbestos in Nevada properties built before 1980 presents a health risk primarily when:
Explanation
Asbestos poses the greatest health risk when it is friable — crumbling or disturbed — releasing microscopic fibers that can be inhaled and cause mesothelioma and other diseases. Intact, non-disturbed asbestos is generally less hazardous.
Q6. The Seller's Real Property Disclosure (SRPD) in Nevada requires sellers to disclose:
Explanation
Nevada's SRPD form (required under NRS 113) requires sellers to disclose all material facts, conditions, and defects known to them that could affect the property's value or the buyer's decision to purchase, including environmental concerns.
Q7. Mold in a Nevada property is considered a material fact that must be:

Known mold conditions are material facts that must be disclosed on Nevada's SRPD. Mold can cause health problems and structural damage, making it a significant factor in a buyer's purchasing decision.
Q8. In Nevada's arid environment, which environmental factor is unique to desert real estate transactions?
Explanation
Water rights are a critical issue in Nevada's desert environment. Water rights may be appurtenant to land or separately owned/transferred. The type, seniority, and quantity of water rights significantly affect property value and permitted uses.
Q9. Which federal law regulates the disclosure and remediation of hazardous substances in real property transactions?
Explanation
CERCLA (Superfund) is the primary federal law governing hazardous substance cleanup and imposes liability on property owners for remediation costs. It is relevant to Nevada properties near mining operations, which historically used hazardous chemicals.
Q10. The EPA requires sellers of pre-1978 homes to give buyers how many days to conduct a lead-based paint inspection?
Explanation
Federal law gives buyers of pre-1978 homes a 10-day period (which can be waived in writing) to conduct a lead-based paint inspection or risk assessment before becoming obligated under the purchase contract.
