Landowner Guidance is an informational resource. It is not personalized legal, engineering, environmental-health, or regulatory advice.

Rules and recommendations can depend on property facts, system type, permit status, effective dates, and state or local authority. Use the applicability and source information on each page, and consult the relevant agency or a qualified professional when your situation requires a definitive determination.

Government information can change. A last-reviewed date describes this site's review history; it is not a guarantee that no source has changed since that review.
