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