New Jersey Environmental
Practice Questions & Answers (2026)
Environmental questions on the New Jersey exam cover both federal environmental laws and New Jersey-specific disclosure requirements. Federal topics include lead-based paint (pre-1978 housing), asbestos, radon, underground storage tanks, and CERCLA liability. New Jersey has additional state-level environmental disclosure requirements enforced by the New Jersey Real Estate Commission — including ISRA (Industrial Site Recovery Act) compliance. Environmental questions trip up candidates who studied only federal law without reviewing the NJ-specific overlay.
