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